As the provider of driving energy, the automobile engine is known as the heart of the automobile. The processing quality of its parts determines whether the engine can output power economically and efficiently to drive the vehicle.
In the processing of automobile engine cylinder block and cylinder head parts, milling is very important. Mainly reflected in the following aspects:
1.Milling processing takes a long time and has a greater impact on the processing cycle of the entire production line
2.The consumption of milling blades accounts for a large proportion of the entire part processing cost
3.The milled surface will be used as the positioning datum between processes, which has a greater impact on the quality of the final product
4.The milled surface is still an assembly benchmark, and its surface quality directly affects the assembly accuracy and performance of the engine
More cutting tools has developed face milling cutter solutions for different workpiece materials based on the characteristics of engine parts.
Aluminum alloy material processing
This tool directly welds the PCD blade to the tool holder, and the axial runout of each tool tip can be precisely adjusted through the adjustment mechanism on the tool holder. The tool holder is locked on the cutter head radially with screws, which occupies a small space, can achieve a dense tooth design, and improve processing efficiency. The blade installation groove is designed as a dovetail groove structure, the tool will not fly out even if the locking screw damages the blade during high-speed processing, ensuring the safety of personnel and equipment.
The cutter head is made of aviation aluminum alloy material, the weight of the cutter head is greatly reduced, and the stability during high-speed processing is improved. The surface of the cutter head has been anodized, and the wear resistance is significantly improved, which is beneficial to improve the service life of the cutter head. The cutter head is designed with an internal cooling structure to ensure a good cooling and chip removal effect.

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.
