  • Reasons for Abnormal Noise in the CNC Machine

    2019-3-30 · One thing to understand is noise will travel. Make sure it is the spindle and not something inline with it. I had a fan on top of my Fanuc spindle that was filthy and had a bearing that was bone dry. The fan would make random noise and often at higher RPM. After removing the fan assembly, cleaning it and repacking the bearing it has gone away.

  • Spindle is making an inconsistent noise.

    Noise. Noise is the first warning sign of a transmission problem. The sooner the problem is caught and repaired, the better: fewer parts will be affected and any repairs will be less expensive. Bearing, gear and shaft wear are the most common causes of noise. As gear tooth faces and bearing races wear, they develop groves and small pits.
