Customer BNow I enjoy our work. Only buy your end mills. Not so much, but only you.
Customer RToday I tested 50HRC 3 flutes end mill for aluminum. It was very very good. Cuts very good. It barely makes a sound.If you stop watching the machine, you cannot say it is cutting.

Common Milling Problems and Solutions
Excessive Chatter: Vibration and sound are excessive when the tool engages the workpiece.
Increase your feed
Reduce your cutting forces by reducing speed and/or feed or axial and/or radial depth of cut
Increase your system′s rigidity by changing over to a stub length end mill or improving your workpiece fixturing
Change geometry - use an end mill with variable flute spacing or a small circular margin
Poor surface finish
Surface Finish: Work surface looks uneven and feels rough.
Increase system rigidity
Change to higher helix geometry
Change to an end mill with more flutes
Excessive Wear of End Mill
Excessive Wear of End Mill: Tool is wearing at cutting edges causing poor performance.
Reduce Speed - A 50% reduction in speed will almost double the tool life
Increase/decrease feed - A feed rate that is too light will cause excess rubbing
Change geometry of the tool - Number of flutes, helix angle, length of cut
Change material grade and/or add a coating.
