How to Maintain a CNC Machine
We all are familiar with the machines like lathe,
milling, drilling, etc. These machines require
human involvement to perform and be monitored.
This way, it consumes more time and has less
accuracy. To overcome this problem CNC (Computer
Numerically Controlled) machines were
manufactured. CNC machines can be defined as the
machines that are controlled by computer and the
operations are performed by inserting the
program. You can consider them as the brain of
the whole manufacturing process. This makes it
even more important to maintain them, because if
it goes down, all the other processes will stop
working. Such failures can cost businesses
thousands of dollars because they have to
instantly find the replacement parts, manage
missed deliveries, etc. To avoid such situations
what we can do is focus on the maintenance of the
machine on a regular basis. And if any part
requires replacement you can easily find good
quality Mazak parts, Fanuc parts, etc.
online. Moving further, let us learn about CNC
machine maintenance in detail.
What Parts of CNC Needs Maintenance? The
maintenance of the CNC machines is not as
complicated as it sounds. It is simple but
critical as no company can afford the cost a
small mistake can

cause. Hence, here is the complete list of the
maintenance steps you need to consider. Coolant
The parts of the machine move fast and this means
it will generate heat. So a fixed coolant level
must be maintained otherwise these parts can get
damaged. If they get damaged you can find good
quality Mazak parts, Fanuc parts, etc.
online. Cooling Oils The speed of the spindle is
around 10,000 RPM and it is obvious that it will
produce heat. Thus, to avoid this thermal energy
a right cooling system with the right
concentration of oils is needed. Lubrication The
moving parts of the machine can get dry and might
need lubrication to reduce unwanted friction.
Thus, using oil or grease on the parts moving
smoothly. The other fluids like hydraulic fluid
in the CNC machine also need replacement. If the
machine consumes fluid excessively, then it
indicates that the machine may have some
problem. Surfaces The grime will build up on the
surface if not cleaned regularly. To ensure a
clean working environment, a good grip and proper
visibility in the room, clean windows, doors,
handles, etc. are important. The other thing that
you need to care about is the sound of the
machine. If the machine is having any slight
mechanical failure, it will sound differently.
You should always consider it as a red flag and
check it intensively. And if any parts need
replacement, you can easily find Mazak
replacement parts, Fanuc replacement parts, etc.

How Often Do You Do Maintenance Checks? A CNC
machine's sensors, detector system, etc. also
gives signals if anything is wrong. Apart from
that you must indulge in a routine based on the
hours of machine used. To save yourself from
doing all the tasks at once, you can divide these
tasks strategically. We have made a list for you
but can change the time intervals as your work
requirements and usage of the machine. Daily
Maintenance tasks Check lubrication levels
and refill if needed Any part that looks dry
must be greased Check coolant concentration
and level add more if required Empty chip
hopper Check hydraulic system levels
Clean surface and the surroundings Monthly
Maintenance Clean or replace air filters
Clean coolant filters Clean radiators
Clean cooling fans Review the checklists for
unusual oil consumption Adjust chains or
conveyors Yearly Maintenance Completely
remove coolant tank and take out metal chips to
check for bacterial growth

Wrapping Up All CNC machines perform different
tasks but the processes like coolants,
lubrications, filters, etc. are common for almost
all CNC machines. Even if a small breakage
happens your in-house team will be able to repair
it in no time if you already have replacement
parts of your CNC machine handy. You will easily
find the Mazak replacement parts, Fanuc
replacement parts, etc. Hence, this way it
ensures your delivery schedule is not affected.
