‣Product Name: Piston
‣Quantity: Production available from 1 to 100 units
‣Material: S45C
‣Product Dimensions: φ132 x 123 mm

‣Process: Stress Relief → Lathe Machining → Machining → High-Frequency Quenching → Grinding → Lathe Machining → Grinding
‣Geometric Tolerance: Coaxiality 0.01

This piston is a component for machine tools (cylindrical grinders).

Due to significant dimensional displacement on the outer diameter caused by high-frequency quenching, stress relief is performed on the pipe material. Despite being thin-walled, it is fully ground to achieve a coaxiality of 0.01.
