Hard Gear Finishing has made some progress in machining accuracy and machining efficiency.


In recent years, a variety of hardened gear surface finishing has made some progress in machining accuracy and machining efficiency, while some new hardened gear surface finishing methods have also appeared. Due to the low efficiency and high cost of grinding, in recent years, foreign countries have begun to study the hardened hobbing process, the use of carbide hobbing can improve the machining efficiency, currently in Japan, Germany and other production has been applied. Domestic in recent years is also actively studying the hardened hobbing process, and has made some progress in the factory production has been applied.


We have used the hardened hobbing process instead of rough grinding, processing efficiency is about 5 to 6 times higher than the conical grinding wheel gear grinding machine. Hardened hobbing process requires hobbing machine tool rigidity, high precision, only in the cutting technology, tools and machine tools and other aspects of the correct coordination, so that the cutting process to achieve the best state, hardened hobbing accuracy can reach 7.

The biggest problem of hardened hobbing is the low precision of tooth shape and unstable machining accuracy. The main reason is: the original formation of the gear involute contour of the internal contact drive chain is realized through mechanical institutions. With the emergence of CNC technology, CNC technology makes each movement of the machine tool to join a servo motor, through the CNC machine tool CNC system, to each servo motor to send pulse commands, each servo motor to get the command, through the motor rotation drive ball screw to realize the movement of the machine tool, so that the original, the formation of the gear involute contour, the internal linkage of the drive chain of the mechanical mechanism to eliminate errors, so that machine tool movement accuracy has been improved. So that the machine tool movement accuracy has been improved. The new CNC hobbing machine will be widely used.

Our professional team of research and development of the second tool hardened hobbing technology has been applied to the factory, through a period of mass production verification, hardened hobbing precision and surface roughness stability is very reliable, representative models YK3612CNC.YK3120CNC.G150CNC and G200CNC.
