parts processing and the top end arc radius, generally speaking, cutter tooth crest blade and side of the blade is linked to wear pointed at high speed cutting processing, especially in the roll. And the top end arc radius of top gear to reduce heat, increase the contact with scraps arc length, thin thickness, improve the scraps tool wear resistance capability and impact resistance stability. Therefore, in the teeth were effectively curve starting round wheels, under the precondition of position requirement can increase tooth crest arc radius.

parts processing technology of cutting is a kind of intermittent rolling process in high-speed cutting, exacerbates the impact of cutter tooth, so we must improve the shock resistance strength knife. Let the flocks, not changing the scraps discharge under the premise of space, reducing groove depth, will let the flocks of tank design into the circular arc to increase the flexural strength of the method can enhance the impact resistance. With the increasing number of traditional rolling circumference, high-speed cutting cutting processing compared to roll the feeding and cutting depth is bigger, if still presses conventional design, then the circumference of each cutting teeth cutting load will then increase. Add circular gear cutting load is one of the effective ways.

parts processing passivation cutting edge tool grinding HSS general new blade obtuse radius for 8-16 muon m, and will have the tiny burrs, if not passivation cause cutting edge collapse of tiny cracks, and also on the blade in coating cannot "station", so the whole passivation need light. Due to the coating will increase after obtuse radius, the coating, the blade can passivation too general passivation to 20 ~ 30 mu m, this helps cut metal cutting edge inside have reduced to wear, before and after the blade knife at the same time, make the cutting edges quickly enter "zili" period, then smoothly into normal cutting period.

Hardware tools using small diameter hob, in a circular hob, linear phase when small diameter hob allows have higher gear hobbing spindle speed. In the production practice, according to the high-speed cutting roller in new situation, the new question and adopt corresponding measures pertinently, can design a really suitable for metal processing high-speed cutting processing of hob, to shorten the gap with foreign advanced hob.
