The intelligent conversation window software of the worm grinder can flexibly design the tooth shape trimming and grinding conditions required by the customer. In addition to the common cylindrical worms of various tooth shapes of ZA, ZN, ZI, ZK, our technical core is in processing tooth thickness Different double-lead precision indexing worms and Niemann worms (ZC toothed worms). The double-lead worms are the key parts of the solar tracking system and the fourth-axis indexing disk of the machine tool. The Nieman worms are equipped with tangential large leads The worm gear is the core component of high-speed rail and subway escalators that can withstand the turbulence of people in an instant. The machining accuracy of general mass-produced worms can reach DIN level 4, and the highest can reach DIN level 2.
