Dealing with Common CNC Machine Repairs

Updated: Aug 23, 2019


What is a CNC machine? CNC stands for computer numerical control; it is a machine used for making precise cuts of a specific material programmed into the computer of the machine. The most common issues for these machines are caused by user error and lack of maintenance. Below we outline the three most common issues customers encounter.


User Error

Not properly maintaining your CNC machine and thoroughly cleaning it after each project can lead to problems. For example, when your device becomes clogged with dirt or any debris, it can clog the filter. When the filter becomes clogged, it can cause the machine to overheat. An overheated machine can be the culprit for more significant repairs if not dealt with immediately or prevented in the first place. Your CNC machine will begin to overheat around 150 degrees Fahrenheit. In the event, your machine does overheat let the system cool down then remove the filter and clean out the debris. Also, clean anywhere else on the machine that grime may be building up.


Machine Chatter (Vibrations)

If your machine begins to chatter while in use there are a few solutions you can try to get the vibration to stop. Not dealing with this issue can significantly reduce the life of your machine.


First, try to cut the width and depth refraction to 1/1000th of an inch. Many machinists will slow down the RPMs to reduce the chattering. Others may even attempt to speed the machine up to solve the problems. Either of these solutions works and are up to the machinist and what makes them more comfortable when dealing with the repair.


Damaged Edges of Your Work

If you are creating a new piece and the edges of your work are being burned, this is a sign the tool is damaged. By repairing or replacing your tool with a sharper one should resolve this problem. You can also try running the machine at a lower speed if replacing the tool isn't an option at that very moment.


RouterCAD is the manufacture of the American made BOSS CNC Router. Their machines come with everything a machinist needs to get the job done without having to buy all the additional parts separately. They also have many CAD/CAM software available to use with your new machine.
