The manufacturer of HRC70 ballnose end mill tells you that due to the small gap between the end mill and the tool holder, the tool may vibrate during the machining process. The manufacturer of HRC70 ballnose end mill tells you that the vibration will make the cutting amount of the end mill circular edge uneven, and the cutting and expanding amount will be larger than the original value, which will affect the machining accuracy and tool life.

The manufacturer of HRC70 ballnose end mill tells you that when the width of the machined groove is too small, the tool can also be vibrated on purpose, and the required groove width can be obtained by increasing the amount of cutting and expansion, but in this case, the maximum width of the end mill should be used. The amplitude is limited to less than 0.02mm, otherwise stable cutting cannot be performed. In normal machining, the smaller the vibration of the end mill, the better.
The manufacturer of HRC70 ballnose end mill tells you that when the milling cutter vibrates, you should consider reducing the cutting speed and feed rate. If there is still large vibration after both have been reduced by 40%, you should consider reducing the amount of cutting. The manufacturer of HRC70 ballnose end mill tells you that if the machining system has resonance, the reason may be due to factors such as excessive cutting speed, low feed speed, insufficient rigidity of the tool system, insufficient clamping force of the workpiece, workpiece shape or workpiece clamping method, etc. At this time, measures such as adjusting the cutting amount, increasing the rigidity of the tool system, and increasing the feed speed should be taken.
