The machining of chamfering, rounding and grooving of all mechanical parts is inseparable from the rotary carbide file. The rotary carbide file can also clean the pipe and clean the inner hole surface of finishing mechanical parts, and the effect is also very good.
To improve the grinding efficiency of the rotary file, slow feed grinding is used to increase the radial feed of the grinding wheel and the slow workpiece feed speed, so as to increase the number of grinding particles involved in cutting at the same time.
Hard alloy rotary file should be sharp cutting edge, the surface should not crack, Nick, chipping edge and other defects affecting the performance, handle teaching part should not rust. There should be no lack of penetration in the welding.
