Computer Numeric Control (CNC) ID grinders are extremely precise machines that are designed to get work done quickly and efficiently. However, without adequate maintenance, CNC ID grinders can malfunction and disrupt production. At Maximum Advantage-Carolinas, we don’t want you to run into this problem. Here are three common malfunctions associated with CNC ID grinders that we want you to be aware of.

Workpiece Burns

If you experience burns on the sides or edges of your workpieces, this is an indication that the grinding wheel has lost its sharpness or that the feed rate is too slow. Inspect and check whether the grinding wheel needs replacing or adjust the feed rate of the machine.


Though a CNC ID grinder is designed to handle pressure, it can be damaged if the temperature gets too high. If the average temperature of a CNC ID grinder gets above 150°C, then the machine is malfunctioning. Inspect the grinder, clear the machine to remove leftover swarf, and make sure there’s no dirt or dust in the filters.


Vibrations, also known as chatter, are the noise that a CNC ID grinder makes when it is in operation. This problem generally occurs because of too much deflection. Though it does not affect the quality of work, loud vibration noises indicate that there is an issue with the machine. This can shorten the lifetime of a CNC ID grinder. Inspect the machine and ensure that deflection is kept under 1/1000th of an inch.
