During machining, the occurrence of the vibration due to the follow reasons:
- The big gap of the main axis shaft bearing, causing the vibration of the main shaft; Adjustment shaft
bearing gap or replacement shaft bearing.
- The rough and uneven surface of the workpiece, the unstable cutting feed caused the unstable cutting force,
so occurred the vibration; The workpiece need to be honed or machining one time firstly.
- The revolution speed, feed rate and cutting force, all the factors effects have the synchronic effect of the CNC
natural vibration; at this time, the whole CNC will have big vibration, the CBN inserts vibration is seriously too.
The federate change is necessary.
- The elasticity of the CBN inserts, the tool holder force of the CBN inserts, happened the vibration frequency
with the cutting force, the part vibration was also caused; the vibration will be eliminated by changed one of
