Tungsten Carbide Fluted Countersink Cutter Chatter Issue

During the machining operation, it is known that the chatter could be occurred easily even when adopting tungsten carbide countersink cutters in the cutting processes. The recommended setup in the machining is shorter and more rigid. Since the tungsten carbide fluted countersink cutters often have more than one flutes at an irregular pitching, which will reduce the smooth action of cutting edge set up. In addition the surface speed of the cutting edges, material type and the feed rate will affect the surface ripple, which is hard to remove once started.

Since if the feed rate is too small the chatter risk is likely to be increased, so the most suggested way to deal with chatter is decreasing the speed, meanwhile, increasing the feed.
