Common Problems With CNC Drilling Machines


CNC drilling machines are excellent pieces of equipment. They are reliable but can be very complex for the inexperienced operator. CNC stands for Computer Numerical Control and the machines that make use of this technology can perform very intricate tasks. Rather than the machine being controlled manually by a person moving hand wheels or levers, the actions are controlled by a computer programme. With such a complex technological devices there are a number of common problems that can occur. There are a number of things to look out for, but most problems are the result of either a lack of maintenance or user error.

How to Avoid the Most Common CNC Machine Problems

There are a number of things to look out for if you want to reduce CNC drilling machine problems.

Chatter – this is the name used when the CNC machine vibrates when being used for a job. It could be the whole machine that is chattering or the tool being used. If the chatter is allowed to continue it will effect the quality of the finished products. The life of the tool will also be severely affected, as well as that of the machine itself.

A Never-Ending Learning Process – it can take a lifetime to learn how to operate a CNC machine, and it is very rare for there to be true masters of the process. With such a machine and the processes it can perform, there will always be new situations and new thinking that needs to be adapted to. As part of the adaption it’s important to always learn from mistakes and not to make them again.

Burns on the Outside Edge of the Material – if this happens it is an easy fix. The burns will be caused by a blunt tool or a feed speed which is too low. Replacing the tool or increasing the feed speed should quickly fix this issue.

Overheating – the internals of a CNC machine get extremely hot when the the machine is being used. Allowing the filters to become clogged with debris will only make this worse. Regular maintenance should reduce the chances of this happening. A regular cleaning schedule is therefore very important. It is also vital to clear away metal shavings and cutting fluid as part of that schedule.
