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.

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
