PCD turning tool processes the combustion chamber on the top of the piston
If the engine is the heart of the car, then the piston can be called the "center" of this heart.
The piston, piston ring, piston pin, and other parts form a piston group, and together with the cylinder head, cylinder wall, and other parts, form a combustion chamber, which bears the pressure of the combustion gas and transmits it to the connecting rod through the piston pin to drive the crankshaft to rotate, completing the working process of the internal combustion engine.
The piston is the busiest part of the engine in a working environment with high temperature, high pressure, and high reciprocating inertia force, and its material performance requirements are very high.
The early piston material was mainly cast iron, but with the development of lightweight automobiles, aluminum alloys gradually replaced it.
Aluminum pistons have the advantages of being lightweight, having low thermal expansion coefficient, good thermal conductivity, corrosion resistance, and wear resistance, but in the processing process, problems such as sticking, built-up edge, large deformation of the workpiece, and deterioration of processing accuracy and surface roughness often occur.
In this regard, the PCD tools provided by Moresuperhard can easily solve these difficult processing problems.
Advantages and characteristics of Moresuperhard's PCD tools:
1. Efficient processing: While ensuring the life of the tool, high-speed processing is achieved to improve efficiency. The life of PCD tools is 10-15 times or even more than that of alloy tools.
2. Stable product quality: While controlling costs, ensure stable product quality, sharp tooltips, and good surface roughness control.
3. Reduce vibration: Less vibration, avoiding screw damage and the trouble of frequent tool changes.
Recently, Moresuperhard received an inquiry from a Thai customer for PCD turning tools to process the combustion chamber on the top of an aluminum piston. The drawings are as follows.
The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form.
Gasoline engines mostly use flat-top pistons, and diesel engine pistons often have various pits on the top.
The figure below is a customer's workpiece processing diagram.
Moresuperhard's engineers confirmed the 3D diagram of the tool with the customer and shared some related cases of piston processing tools. The customer trusts the solution provided by Moresuperhard very much.
Moresuperhard can provide customers with a complete set of piston processing tool solutions. The relevant processing technology is very mature, and targeted suggestions can also be provided for problems that often occur during processing.
The quality requirements of the piston are strict, and the processing technology and precision are inseparable from the performance and life of the engine. Moresuperhard always takes customer needs as its starting point and can provide tools and services that exceed customer expectations.
