Abstract
The invention discloses a machining process of a milling cutter with a coating. The machining process comprises the following steps: 1) carrying out external grinding for coarse material steel to obtain blank; 2) rolling grooves in the blank, cutting into the needed length, and obtaining a workpiece with a blade groove; 3) carrying out coarse external grinding for the workpiece with the blade groove; 4) edging the workpiece after coarse external grinding; 5) carrying out accurate external grinding for the edged workpiece; carrying surface treatment for the workpiece after accurate external grinding; 7) putting the workpiece after surface treatment in high-oxidation-resistance hard coating sol for 10-15 times of dipping, and then drying; keeping each time of dipping for 30-65 seconds, and keeping the drying temperature at 85-155 DEG C; and 8) putting the workpiece with the coating in a vacuum furnace to sinter at 1250-1450 DEG C to obtain the finished product milling cutter. The machining process is simple, and the machined milling cutter has high toughness, hardness and strong high temperature oxidation resistance.
