Hob tooth relief grinder

Dec 10, 2020

May 12, 2021 Abstract. Gear hob is an important tool that is most used in gear processing. Hob accuracy directly exerts an overwhelming influence on the quality of the processed gear. Generally, the hob tooth profile accuracy is mainly determined by relief grinding process
