Deburring Polishing Media and compounds
  • Polishing Medias are used for -
  • Cutting  Media which can cut, remove burrs and
    can smooth surfaces. Deburring media refers to
    materials that enable burr removal while not
    harming the other parts of the material or parts
    surface.
  • Luster  designed to promote luster on the
    surface of metal parts.
  • Part separation  To separate parts during the
    de-burring, cutting, surface improving or
    burnishing operations
  • Surface scrubbing  Media have the unique ability
    to scrub surfaces and physically assist compounds
    in their cleaning function
  • Widely used Polishing media are
  • Aluminum media  Aluminum media are typically
    cast parts and are available in a wide variety of
    shapes and sizes. Aluminum scrubs parts and can
    work in conjunction with cleaning compounds to
    clean parts
  • Preformed Ceramic  manufactured by mixing clay
    materials and water with abrasives, forming the
    mud into shapes, drying the shapes, and firing
    them at high temperatures to vitrify the binder
  • Preformed resin- bonded media Plastic or
    resin-bonded media utilize a wider range of
    abrasive types and sizes than preformed ceramics.
    The most popular grades are those using Aluminum
    oxide, silicon carbide and other abrasives.
  • Steel Case hardened, Available in a variety of
    sizes and configurations. Balls, balls with flat
    spots, diagonally cut wire similar to angle-cut
    cylinders, ball cones and cones and pins are the
    most commonly used and are being more widely used
    for light de-burring applications and cleaning.
    Compounds are available to keep steel burnishing
    media clean and bright for extended periods.
  • Synthetic random shaped media Most popular
    synthetic random media is fused aluminum oxide,
    which is available in a number of grades. The
    more loosely bound, coarse-grained materials are
    characterized by fast cut and high depreciation
    rates.
  • Natural Random-shaped Media  Granite, quartz,
    limestone, emery and other naturally occurring
    abrasive materials are also used in vibratory,
    tumble finishing applications
  • Cob Meal, walnut-shell flour  These are used for
    drying applications because of the natural
    ability of these materials to absorb water from
    metal surfaces. These can also be blended with
    abrasives and used for fine-polishing
    applications in vibratory, barrel, or spindle
    finishing equipment.

Ceramic deburring and polishing media for surface
finishing
  • made by mixing clay and other vitreous material
    with different abrasives, used for all types of
    metals and gives various finishing from light cut
    to aggressive deburring and cutting depending on
    the grade of abrasive, Ceramic Deburring and
    Polishing Tumbling Media is recommended for
    general purpose polishing, light and heavy
    deburring of ferrous and nonferrous metal surface
    made of lost wax casting, forging or sand
    casting.This media use leads to extra fast
    deburring and ultra-aggressive metal removal from
    the surface. Ceramic media is best for heavy
    cutting and hard metals. When a small media is
    required (under 3/4"), ceramics offer the best
    selection. Ceramic media supports very heavy
    parts better than plastic media due to its
    hardness and abrasive properties.Advantages of
    Ceramic Tumbling Media are its Durability,
    inexpensiveness and highly versatile, ceramic
    finishing media is the most common media used in
    mass finishing. It is manufactured in a wide
    variety of precise shapes which assists in
    separation and elimination of lodging
    problems.Ceramic Deburring, polishing and
    finishing media is made of silica and other
    minerals and abrasives that are combined, formed
    and fired at a high temperature producing a very
    hard cement-like product. Most ceramic preformed
    shapes such as triangles, stars and ellipses are
    extruded and cut to the desired length. The
    density of ceramic preformed shapes is usually
    determined by the amount of abrasive incorporated
    into the mix prior to firing the more abrasive
    the higher is the density and darker the color of
    the media. This is important because the higher
    the density the more aggressive the media will
    be (faster cutting and rougher surface) and the
    quicker it will wear. Therefore, dense media is
    only practical where the objectives cannot be
    achieved by any other way or where the reduction
    in cycle time brings a greater value than the
    extra cost in media consumption.The type and
    quantity of abrasive grain can be varied to
    accomplish particular tasks, depending on the
    bond material selected and used in manufacturing
    of the media, It can be supplied in small or
    large quantities such as Tumbling stones, ceramic
    chips, deburring media, polishing balls are all
    synonyms for ceramic tumbling media available in
    many sizes, shapes and formulations for immediate
    delivery. High density ceramic media is also
    available as per the product deburring and
    polishing requirements.Preformed Ceramic
    manufactured by mixing clay materials and water
    with abrasives, forming the mud into shapes,
    drying the shapes, and firing them at high
    temperatures to vitrify the binder.

Corncob Polishing and Drying Media for surface
finishing
  • This media is used mainly for drying
    applications, polishing, shinning because of the
    natural ability of these materials to absorb
    water and oil from metal surface and is also very
    effective in removing the tarnish from brass
    castings. It being environment friendly has long
    life and is reusable. Both treated with polishing
    paste and untreated corn bob media is available
    whereas in treated media comes with polishing
    compound already mixed or blended with abrasives
    and used for fine-polishing applications in
    vibratory, barrel or spindle finishing equipment
    and getting treated media is best option to avoid
    worrying about the polish mix quantity to be
    added for a particular job of polishing. our
    unique  processing provides the most accurately
    sized, screened and air-washed grit in the
    industry with strict management of the quality
    control to ensure product consistency and
    customer satisfaction with customized production,
    bagging and blending.
  • The hardest part of the corncob is useful for
    abrasive applications with grinding and polishing
    paste whereas the pith and chaff are the most
    absorbent parts of the corncob for drying water
    and oil on the product surfaces.
  • Different cob grit sizes are available as per the
    customer requirements, whereas the larger grain
    size media has negative effects compared to
    smaller or finer media size for tumbling and
    vibrating, in the vibrator the corncob media
    cleans better as it is constantly being shaken
    and the quantity of the media in vibrator is also
    a major experience so that the contact of media
    with the product to be polished is most and
    pieces dont strike with each other, generally
    the tumbler capacity is divided by six parts in
    which 4 parts of media is used and 1 part of the
    product to be polished and 1 part is free for
    movement of the media to avoid scratching of the
    castings by volume. Life of corncob media depends
    proportionately to the time span of use as with
    the dirt, oil or tarnish the polishing process
    slows over a time, when the required finishing is
    not acceptable the media should be changed and
    recharged with the polishing compound or paste we
    should charge or treat the media first with the
    compound and then use the same for polishing and
    shinning processes

Glass Beads polishing and deburring media
  • Glass beads high polishing media, these are
    silica and lead free used as abrasive media for
    deburring, cleaning, polishing and blasting.
    Mainly used on metal, glass, plastic and rubber
    surfaces for a uniform and smooth shinning with
    bright finishing.

High density Polishing and shinning Media for
surface finishing
  • High density Polishing and shinning Media are
     zirconium oxide ceramic micro beads, zirconium
    silicate ceramic micro beads, Zirconia Toughened
    Alumina Beads and 92- 99 plus Purity High
    Alumina Ceramic balls,  formed by using ultrafine
    powder as a raw material and then densified by
    high-temperature sintering between 1400-1600
    degrees,  it is a High density polishing and
    shinning media combined with the shining
    compounds and are suitable for each type of
    metal, has  remarkable advantage to eliminate the
    problem of oxidation that usually involves in the
    traditional stainless steel balls,  with this
    product there is no transfer or oxidization of
     metal during the process, therefore no more acid
    degreasing and there is a minor discharge of
    water. The remarkable hardness and the low
    specific gravity permits to obtain a very fine
    finish without the orange peel phenomenon that
    frequently involves the traditional treatments
    with stainless steel balls. Another important
    characteristic of this material is that it allows
    the processing of very thin and fragile objects
    (i.e. in the gold industry), assuring with one
    single step smoothing and shining without
    modifying the color and the natural
    characteristics of the metal, this high density
    polishing media is free from pin holes, cracks
    and has  dense homogeneous internal micro
    structure which leads to satin smooth surface
    finish,The media is extremely gentle to
    expensive polishing parts as wear of polishing
    parts is extremely low or negligible and reduces
    abrasion resulting in lasting life which is
    approximately 300-350 times longer than glass
    beads, it has higher density as compared to any
    other ceramic micro milling and polishing beads
    so can generate considerable heat during
    polishing process and which may affect physical
    properties of ingredients being polished hence it
    is  recommended to provide suitable cooling or
    polishing solvent to the polishing tumbler also
    Smaller the media size larger the number of
    contact points resulting in reduced polishing
    time, enhanced productivity and intensity of the
    shinning ideally suited for shot peening
    treatment on metal surfaces, metal polishing,
    contact eye lenses polishing and a host of many
    other applications. It is highly resistant to
    chemicals, most acids, Corrosive liquid, most
    solvents

Plastic Deburring Polishing and smoothing Media
for surface finishing
  • Plastic Deburring Polishing and smoothing
    tumbling media is a preformed resin-bonded
    abrasive media, more commonly recognized as
    plastic media is utilized in a wider range of
    abrasive types and sizes than preformed ceramics.
    The most popular grades are those using quartz as
    an abrasive. Aluminum oxide, silicon carbide
    along with other abrasives. Usually, low-cost
    polyester resins are employed as the binder and
    the various shapes are produced by casting the
    resin bonded media in different grades and sizes
    which is good for all metal surfaces deburring
    and polishing.
  • This Deburring and polishing media is a
    petroleum-based plastic media used for low micro
    finishing and where the polishing must be free of
    impingement damage in nonferrous metals and other
    soft materials, a blend of urea formaldehyde
    resin and abrasive material of aluminum or
    silicon carbide is added in plastic deburring
    media and has lower specific gravity making it
    useful for delicate items, Plastic media are
    softer, more flexible and therefore normally used
    exclusively on non-ferrous products.
    manufacturing process of plastic media shapes is
    the same as ceramics, plastic comes in  different
    types of bonds and many more shapes because they
    are molded rather than extruded like their
    ceramic counterparts. The two types of bonding
    materials used are polyester and urea, one good
    feature of plastic media is that it is formulated
    with colors for easy identification of
    compositions or coarseness and abrasive
    properties of the media.
  • With wide range of different types of plastic
    media chips and compounds for different finishing
    requirements it is majorly used for solving
    challenging finishing, burnishing, edge breaking,
    radiussing, polishing, de-flashing and deburring
    of nonferrous metals such as silver, gold,
    aluminum and brass items and is less hard than
    the ceramic media therefore leading to less
    pressure on the parts as it works by weight and
    pressure on the parts also helps to form a
    cushion around each part in polishing machine
    avoiding collision between the parts being
    polished, has longer life as are wear resistant
    and leads to surface smoothing with minimum
    material removal from the product surface giving
    uniform finishing. Plastic polishing media use is
    a wet process in which a small amount of liquid
    compound with water is used to damp the media and
    keep the process clean with brighter surface

Surface Polishing, Etching and Blast media
  • Abrasive blasting is the general term applied to
    finishing processes in which high-pressure
    propulsion of a stream of abrasive material
    called media is shot onto the surface of a
    workpiece with or without water. This process
    serves many surface finishing purposes as
    removing contaminants, previous coatings and
    paints, waterjet cutting, powder coating,
    porcelain coating and light rust removal without
    altering the shape and for roughening the
    surface, matte finish etc.  We offer different
    types of blast media such as metallic, plastic,
    glass bead, fused alumina, walnut shell, corncob
    and ceramic media etc. that enables our customers

  • Few of the most appropriate material for your
    specific finishing requirement are as following
  • Steel Shot and steel Grit   steel media is among
    the cost effective alternative to other abrasives
    media, it is very tough and recyclable, used on
    variety of surfaces to remove contamination,
    cleaning, stripping and improving metal surfaces
    and get required texture before plating, also
    used as peening media to get the surface
    hardness, here the correct shape, size and
    hardness of the media  plays a significant role.
    steel shots are round in shape resulting in
    smooth surface, peening with steel shot produces
    improved compressive strength on metal surface
    also used  for  Heat Treat Removals, Mill Scale
    Removal, Paint Removal, Sand Removal from
    Castings, Pre-Paint Adhesion, Peening etc.
  • Aluminum Oxide   It is a long lasting media with
    highly sharp angular properties used for
    profiling ,etching, industrial application as a
    blast media, predesigned for abrasive pressure
    blasting of almost all types of substrate  for
    deoxidizing, Cleaning of investment castings,
    Scale removal in steam turbines, Surface
    preparation for thermal spray coatings, Rust
    removal, Hard oxide removal from titanium and
    zirconium metals, Mill scale removal, Heat treat
    scale removal, antiskid etching, Glass etching or
    frosting, Matte finishing, pickling and surface
    preparation of marble, steel, glass, granite etc.
    It has superior hardness and strength  and has an
    ability to deep etch on the metal product surface
    so used for surface polishing prior to painting
    and coating to increase the surface roughness of
    the metal part before paint and coating, helps in
    deburring and cleaning paint and lacquer
    layers, Aluminum Oxide is widely used as a tough
    recoverable media and When propelled by air it
    acts as a powerful multi-edged abrasive tool that
    will penetrate the work piece while leaving an
    exceptional clean and etched surfaces. It is used
    on metal, glass, ceramic, marble, granite and
    other stone surfaces.

Surface Polishing, Etching and Blast media
  • Glass beads  the shape of this media is
    spherical and is non porous, it is hard and has
    very low abrasiveness suitable for cleaning and
    polishing of small metal parts of soft metal.
    Media is silica free used for satin and matt
    finish with minimum stress on parts, this media
    is not as aggressive blasting media as other
    materials such as steel shot or aluminum oxide
    but is an excellent choice for applications that
    require a softer, brighter finish. Media can be
    recycled multiple times. This media generally
    gives a brighter matte finish. It maintains
    tighter work piece tolerances cleans and prepares
    the surface of metal parts without changing
    tolerances or imparting ferrous pollutants.
    Combines cleaning, finishing and peening in one
    operation. creates a wide range of unique surface
    finishes that are easy to reproduce also reduces
    the tensile stress in metal parts and increasing
    the fatigue limit.
  • Crushed Glass   This media is  made from
    recycled glass very economical and mainly used
    for stripping purpose the angular nature of glass
    media allows for aggressive surface profiling and
    removal of coatings and surface contamination
    paint stripping, rust removal, etching on
     aluminum and stainless with wet blasting.
  • Plastic media  Plastic blast media is soft and
    very soft in nature with various hardness and
    aggressiveness characteristics mainly used in
    automotive applications Plastic abrasive is a dry
    thermoset cleaning media made from crushed urea,
    polyester and acrylic. Each varying and available
    in a range of hardness and particle size,
    generally regarded as the best media for mold
    cleaning, blasting of plastic parts and in
    applications where the removal of the substrate
    material is not permitted such as aircraft Paint
    Removal Removes, most types of paint from typical
    aircraft parts and leaving anodized surfaces
    intact, Paint stripping from aluminum, fiberglass
    and dense hardwood hulls, It cleans brass of
    oxides and other coatings. Burr Removal Removes
    light burrs from components while maintaining
    integrity of finished parts, it is the only media
    capable of removing resin bleed without opaquing
    surface, Composite Structures Can strip paint and
    surface coatings from fiberglass, epoxy, and
    other resin rich components without bloom or
    fiber damage.
  • Silicon carbide  An extremely aggressive media

  • Walnut shell   is used for applications that
    require aggressive stripping or cleaning without
    damage or effect on the underlying substrate.
    Organic and biodegradable, Walnut Shell Grit is
    extremely durable, angular in shape but is
    considered a soft abrasive. Walnut Shell Grit
    sees utility in applications such as cleaning
    hard woods and aircraft and automotive stripping,
    this is a natural ecofriendly product derived
    after crushing the walnut shells and is harder
    than the soft abrasives, available in different
    grit sizes used for blast cleaning, de-flashing
    and polishing soft surfaces of soft metals, wood,
    plastic, fiberglass, epoxy and stone also used
    for polishing in centrifugal tumblers for
    polishing of jewelry, fiberglass, cutlery,
    plastic and resin products and for removal of
    graffiti from wood products.
  • Corncob  is an organic, soft blasting grit that
    is safe for delicate parts and soft substrates.
    As the preferred blasting media for log homes and
    other wood surfaces, Removing paint from delicate
    surfaces it offers excellent cleaning and
    stripping properties without damage to the
    substrate.
  • Ceramic Blasting Media  this media is very
    durable and highly efficient as blasting media
    giving smooth surface without contaminating the
    surface of the product where we achieve uniform
    surface profile with matte finish , is round in
    shape giving smooth surface. This blast media is
    recommended for stainless steel, aluminum ,
    magnesium, brass, copper and plastic products.
  • Blasting Media Selection Guide  It is important
    to know the differences in blasting media, since
    different abrasive blasting media are required
    for different applications. Blasting media can be
    used for purposes such as cleaning, stripping,
    etching, strengthening and polishing. In addition
    to the media type, grit or mesh size is another
    factor to consider for your application. The
    final choice of media depends on the nature of
    the work required and on the blasting equipment
    that is employed. The blasting media selection
    guide contains a list of the common blasting
    media and the differences in blasting media,
    Things to note for correct choice of blasting
    media to achieve the desired surface finish is to
    strike a balance between price and effectiveness
    of the blasting media and different factors play
    a major role in the final polishing results.

Porcelain high polishing Mediafor Surface
finishing
  • Porcelain polishing Media-
  • Porcelain polishing media is traditionally made
    of silicate mineral that gives it its plasticity,
    translucency, structure and hardness, it is also
    a non-porous option of ceramic media with pure
    aluminum oxide and has high durability due to
    firing at very high temperatures ranging from
    1200-1400 degrees, this media gives minimum
    abrasion depending on main composition  aluminum
    oxide in it  and is mainly used for polishing
    processes in vibrators and centrifugal disc
    polishing machines and is a great cleaner
    polisher for all types of metals, the chemical
    composition of this media makes it excellent
    choice for burnishing and polishing of plastic
    and metal components and is used mainly in the
    final step of different processes of metal
    finishing giving finer grinding and high gloss
    finish in wet polishing process with recommended
    polishing compounds.
  • Generally four different structures of porcelain
    media is used in different sizes depending on the
    component geometry to be polished and unlike
    steel polishing balls it does not dent the
    surface of the product, Porcelain polishing media
    is used on soft and hard metal as it polishes the
    surface without removal of the material giving
    high polishing effect and being used mainly for
    polishing- surface improvement and bright shinny
    surface, has no abrasive wear out and has high
    life. We can suggest the best polishing and
    deburring media to be used in the vibrators and
    disc polishing machines after evaluation of the
    product to be finished or polished. Media is
    available in different sizes and shapes as per
    your requirements and we can help you to find the
    best suitable media.

Steel polishing, deburring and burnishing media
for surface finishing
  • Stainless steel polishing media is used mainly
    for burnishing in vibratory and centrifugal
    tumblers and magnetic tumblers for surface
    finishing, Steel media is used for burnishing,
    deburring, de-flashing, pre-powder coating
    finishing, mirror and matt finishing, de-rusting
    and degreasing etc with the help of centrifugal
    and vibrator polishing machines eliminating
    manual buffing and improving the surface of the
    components, it is free of abrasive particles and
    mainly used for light deburring, lapping and
    cleaning articles
  • The stainless steel media is available in
    different sizes and shapes as per requirement
    such as ball, cones, diagonal pins, cross pin,,
    sphere balls, eclipses which help in polishing
    brass, zinc, steel , gold, silver and aluminium 
    parts ranging from thin delicate wires to
    roughest industrial components enhancing shine on
    varied metal surfaces.
  • Stainless steel Magnetic polishing media   steel
    pins and balls are specially made to work with
    magnets in the magnetic polishing machines with
    special chromium alloy steel avoiding rust of the
    steel media and free movement with the magnets of
    the tumbler, different thickness pins are
    available for magnetic polisher and application
    as larger size make heavier impact on soft metal
    surfaces therefor lighter pins are used for gold
    and silver products or soft metals, Most used
    magnetic polisher pin sizes vary from 3mm-10 mm
    length and diameter of 0.2 to 1.5mm depending on
    the product to be polished lower the size and
    thickness of these pins lower is the impact on
    the products, When using Stainless Steel Shot
    Pins the amount of media should be equivalent to
    the amount of parts used for tumbling. If these
    amounts are incorrect, it can affect the final
    finishing process of products and result in
    non-satisfactory results

Walnut Shell Dry Deburring and Polishing Media
  • Walnut shell polishing media is a fibrous and
    hard product made after crushing the walnut
    shells and is ground to different sizes from very
    fine to coarse as per the application for dry
    polishing and dry deburring, walnut shell
    polishing media is then treated with polishing or
    deburring paste which has varying additives of
    quartz and aluminum oxide in it for high and low
    abrasiveness even to mirror polish soft metal and
    alloys, plastic, glass, fiberglass, resin, stone,
    rock and many more products and untreated walnut
    shell media is used mainly to clean metal or
    nonmetal surfaces. It is used mostly in vibrating
    tumblers, rotating tumblers and centrifugal disc
    polishing machines mixed with creamy abrasive
    pastes of different properties as per the
    requirement of surface finishing. The walnut
    granules are recommended for deburring,
    smoothing, polishing and mirror shining. Walnut
    shell is widely used for cleaning and polishing
    of tarnished brass products, aluminum parts,
    shell cartridges, eyeglass frame and lenses,
    ivory products, mechanical parts, gems and
    jewelry of all metals with and without studding,
    watches, zinc castings parts. With coarse
    deburring paste to remove burrs wets, corners,
    edges without scratching or etching the product
    being polished, it is extremely durable
    multi-faceted and angular in nature and is known
    for its soft polishing nature advantages, it is
     ecofriendly biodegradable product and can be
    reused with long lasting life depending on the
    time used and roughness of the surface of walnut
    and product to be polished.
  • Most used process with walnut shell for polishing
    is dry deburring with high coarse polishing paste
    impregnated on it and subsequent polishing and
    smoothing or shinning with low coarse paste
    impregnated on the walnut shell media for final
    shine of the products i.e two different Dry
    polishing process- first for Dry deburring and
    second Dry Polishing or final polishing of the
    surface.
  • The recommended quantity is calculated as per the
    capacity of the vibrator or centrifugal tumbler
    where it is filled with 4/6 by polishing media
    and 1/6 is the product by volume and rest 1/6 is
    left empty for the media movement, after the
    media starts moving more products to be polished
    can be added with a precaution that they dont
    strike with each other leading to denting or
    scratching on the surface and each product should
    be completely surrounded by the polishing media
    throughout the entire run, too much of media will
    avoid the adequate tumbling action in the barrel
    and lesser amount of media will lead to products
    denting each other. Ratio of media to products
    and tumbler capacity can be concluded with
    experience.

  • Wooden Deburring and polishing Media is specially
    chosen and cut for optimal performance in dry
    deburring and polishing of studded jewelry items
    and light products of different materials, which
    in combination with Finishing and deburring paste
    is ideal for deburring and surface smoothing of
    metal (ferrous and nonferrous) and nonmetal
    products.Benefits no water required, near
    mirror finishing with consistent surface finish,
    light weight so does not dent the product surface
    and can be used in dry vibrators to polish
    plastic, resin, horn, acetate and metal frames,
    plastic goods , wooden items and different
    metals, dry deburring and polishing is done by
    removing the scratches and pits with abrasive
    paste where the abrasive particles are much
    harder than the product ( metal and nonmetal) to
    be polished and these particles work as tool bits
    and its size is so small that it does not dent or
    scratch the surface the product to be polished
    and it does so on the microscopic level and
    increases friction at the surface where it
    interface with media and heats a thin layer of
    the product surface that tends to flow rather
    than cut the surface.In dry polishing and
    deburring process the abrasive paste and wooden
    media grades play a major role to remove the
    deepest defects of the surface and then the finer
    grades are used to remove the scratches from
    deburring grade polishing paste used
    earlier.Wooden polishing media should be renewed
    regularly by removing the paste deposited on the
    wooden media surface or use fresh surface as per
    the requirements.
