01 Advantages of aluminum piston

Piston is one of the important parts of the engine, aluminum alloy is a special alloy, it has light weight, low coefficient of thermal expansion, good thermal conductivity, corrosion resistance and wear resistance and a series of advantages, its main material for aluminum silicon alloy, silicon content is more than 12%, applied in the automotive engine.

02 Aluminum piston ordinary tools processing easy to wear

With the development of aluminum alloy materials for manufacturing aluminum piston, the cutting tools used for machining piston have been developing continuously.

The hardness and wear resistance of high-silicon aluminum alloy are higher than those of other aluminum alloys. When cutting, the tools alternately cuts the soft aluminum base and the hard silicon particles. It is easy to wear the ordinary tool.

03 Aluminum piston PCD tools processing advantages

PCD tools in processing aluminum, cast aluminum, aluminum alloy and other aspects has advantages, and the processing life of PCD tools is carbide tools several times ~ dozens of times, so PCD tools cutting aluminum piston has many advantages, first of all, it has high hardness, wear resistance and other advantages, followed by the tools sharp cutting force is small, processing surface roughness can meet the process requirements of aluminum piston, Improve the processing efficiency, but also pull down the cost, so PCD tools in aluminum piston processing has been widely used, especially in batch processing manufacturers.

Carbide tools life is several times ~ dozens of times worse than PCD tools

According to different processing requirements, Zhengzhou Halnn super hard not only has PCD blade, PCD milling cutter, PCD drill, PCD reamer, PCD forming cutter, PCD cutter and PCD non-standard cutter customization and other options, but also tailors a complete tools processing overall plan for customers, is the leading enterprise of super hard materials in China.
