Development of Modern Hobbing Technology and Reasonable the of Hob
Xu Zhenguang
NC technology Promotes the development of hobbing technology.With the application of solid hobs with multi-grooves, gear machining technology come up to a new level.Although built-up hobs are being replaced by solid hobs with multi- grooves in advanced countries, built-up hobs with high Precision and high efficiency are still superior to standard solid hobs. At present, advocating the use of built-up hobs in the efficient way to enhance the gear machining level in China.
