Gearbox is one of the core parts of automobile.
Gearbox housing is the basic parts of transmission. Its main function is to support each transmission shaft, to ensure the center distance and parallelism between each shaft, and to ensure the correct installation of the gearbox housing parts and the other parts which connected to them. It also affects the working accuracy and service life of the car, so the quality of the gearbox housing should be very good. It is particularly important to use the proper and superior tools.
The shape of the gearbox housing is complex, and most of them are thin – walled. The tool design should fully consider to avoid the phenomenon of vibration caused by low rigidity and low strength. Due to the complex shape and large quantity holes, it requires numbers of tools.
PCD tool has good cutting performance and chip breaking and chip removal, it can obtain high dimensional accuracy and surface roughness. At present, die-cast aluminum gearbox housing is one of the mainstream materials, and PCD tools are recommended to process this kind of material.

Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
