The piston is one of the important components of the engine, and aluminum alloy is a special alloy that has a series of advantages such as light weight, low thermal expansion coefficient, good thermal conductivity, corrosion resistance, and wear resistance. Its main material is aluminum silicon alloy, with a silicon content of over 12%, which is mostly used in automotive engines.

PCD tools have always had advantages in processing aluminum, cast aluminum, aluminum alloys, and other aspects, and the processing life of PCD groove cutting tools is several times that of hard alloy tools.

LINKUT PCD tools have many advantages in cutting aluminum pistons. Firstly, they have advantages such as high hardness and wear resistance. Secondly, the sharp cutting force of the tool is small, and the surface roughness can meet the process requirements of aluminum pistons, improve processing efficiency, and also lower costs, Therefore, PCD tools have been widely used in the processing of aluminum pistons, especially for manufacturers of batch processing.
