    transmission component in India since 1987. The
    facility comprises of 3 work shops of sizes 800
    sq. mts, 1000 sq. mts, 4000 sq. mts. With a
    complete stand by power for the entire premises.

MANUFACTURING PROCESS
  • HOBBING-

8
PROCESS
  • Hobbing is a machining process for making gears
    splines. which is a special type of milling
    machine. The teeth or splines are progressively
    cut into the work piece by a series of cuts made
    by a cutting tool called a hob. Compared to other
    gear forming processes it is relatively
    inexpensive but still quite accurate, thus it is
    used for a broad range of parts and quantities.
    It is the most widely used gear cutting process
    for creating spur and helical gears and more
    gears are cut by hobbing than any other process
    since it is relatively quick and in expensive.

9
SHAPPING-
10
PROCESS
  • A gear shaper is a machine tool for cutting the
    teeth of internal or external gears. The name
    shaper relates to the fact that the cutter
    engages the part on the forward stroke and pulls
    away from the part on the return stroke, just
    like the clapper box on a planer shaper. The
    cutting tool is also gear shaped having the same
    pitch as the gear to be cut.

11
BROACHING-
12
PROCESS
  • Broaching is a machining process that uses a
    toothed tool called a broach to remove material.
    This are two mainly type of broaching (Horizontal
    Vertical). It is the most common used process
    to cut internal gear quick and more accurate.
    Broaching is used when precision machining is
    required, especially for odd shapes. Commonly
    machined surfaces include circular noncircular
    holes, splines, key-ways and flat surface.

13
SHAVING-
14
PROCESS
  • Gear shaving is basically a finishing operation.
    This takes place after the operations of roughing
    with a hob or cutting with a shaper cutter is
    over. The Shaving process consists of the removal
    of tiny particles of metal from a gear teeth's
    working surface. Gear shaving produces fine hair
    like chips. The cutter comes in the form of
    helical gear. It has special serrations in the
    flank area of gear teeth. These serrations act
    as the cutting edges.

15
ADVANTAGES
  • Improves tooth surface finish.
  • Effective reduction in the noise of gears with
    modification in the tooth profile.
  • Increase the gears load capacity Improved safety
    and service life.

16
SHOT BLASTING-
  • Shot Blasting is the process after Heat
    treatment in which remove the product darkness
    which occurs in heat treatment process . In this
    Process 52 to 60 HRC stainless steel particles
    strike on product.

17
  • DEBBURING-
  • Gear deburring machines are designed to
    correctly remove burrs or sharp edges as a result
    of castings, drilled holes, cut grooves and other
    machining operations used to complete parts. The
    Deburring process of gears makes the parts
    capable of a performance for which they were
    designed. It eliminates all the unwanted elements
    that obstruct their productivity.

18
  • ROUNDING-
  • Rounding is a process in which the tooth sharp
    corner is cut by the
    rounding cutter. A rounding cutter is an
    exterior corner is called a "round" or a
    "radius.

19
  • LAPPING-
  • Lapping is a machining operation, in which two
    surfaces are rubbed together with an abrasive.
    The one type of lapping (called grinding),
    typically involves rubbing a brittle material
    such as aluminum oxide, emery, silicon carbide,
    diamond, etc., in between them. This produces
    microscopic conchoidal fractures as the abrasive
    rolls about between the two surfaces and removes
    material from both.

20
  • GRINDING MACHINE-

21
  • PROCESS
  • Grinding machine consists of a power driven
    grinding wheel spinning at the required speed.
    The grinding head can be controlled to travel
    across a fixed work piece or the work piece can
    be moved while the grinding head stays in a fixed
    position. Very fine control of the grinding head
    or tables position is possible using a vernier
    calibrated hand wheel, or using the features of
    numerical controls.

22
  • Turning machine-
  • Turning is the process where by a single point
    cutting tool is parallel to the surface. It can
    be done manually, in a traditional form of lathe,
    which frequently requires continuous supervision
    by the operator, or by using a computer
    controlled and automated lathe.

23
  • Hard turning 
  • Hard turning is a turning done on materials with
    a Rockwell C hardness is greater than 45. It is
    typically performed after the work piece is heat
    treated.
  •  
  • Soft turning
  • Soft Turning is turning done to soft materials
    which are without heat treatment process and its
    hardness is lower than Rockwell C hardness 45.

24
  • HEAT TREATMENT PROCESS-

25
PROCESS
  • Heat treatment process is a series of
    operations involving the heating and cooling
    of metals in the solid state.  Its purpose is to
    change a mechanical property or combination of
    mechanical properties so that the metal will be
    more useful, serviceable, and safe for definite
    purpose. By heat treating, a metal can be made
    harder, stronger, and more resistant. No one
    heat-treating operation can produce all of these
    characteristics. In fact, some properties are
    often improved at the expense of others. In being
    hardened, for example, a metal may become
    brittle.
