Precision gear hobbing machining precision gear car chat
After heat treatment of automobile gear finishing needs to obtain the required size and precision drawing, so I chose Automotive gear finishing tool material is very important. As the saying goes "we must first of its profits", the importance of the tool machining automotive gears throughout the whole story, the choice for high-quality tool brings not only a complete automobile gear parts, more big improve work efficiency and save processing costs.
Select the appropriate tool material finishing automobile gear according to the hardness after heat treatment of automobile gear.
Processing after heat treatment hardness HRC45 the following automobile gear: Choose carbide cutting tools more appropriate, due to the low hardness of carbide cutting tool body itself, suitable for processing timing gear, or a car engine camshaft gear and other low hardness such as automotive crankshaft gear, such as high hardness processing tool car gears can not move or processed severe wear phenomenon.
After the heat treatment processing hardness HRC45 or more cars Gear: You can also choose ceramic cutting tools and cubic boron nitride cutting tools (CBN Tool), choose what kind of tool in accordance with its processing quality and economic decisions. Ceramic cutting tools have good thermal chemical stability, but not as cubic boron nitride cutting tools toughness and hardness. Hardness of less than 50HRC after heat treatment these small depths of cut and small feed when finishing car gear, ceramic tool is a better choice. For more than HRC50 hardness after heat treatment and the presence of intermittent automobile gear, choice of China Valin superhard cubic boron nitride cutting tools is more suitable. Valin cubic boron nitride cutting tools using non-metallic (ceramic) as a binder, as compared with conventional CBN tools increased toughness, finishing automotive gear only when high hardness, wear resistance and impact resistance, and precision high, enabling high-speed cutting, not only improve the processing efficiency and reduce processing costs. Viewed from above for precision gear hobbing still have some difficulty, Jiangsu Silver Leaf Transmission Ltd Precision gear hobbing technology is mature, with many being the trust of customers.
