Spheroidal graphite cast iron piston

Spheroidal graphite cast iron piston

Commercial cast iron piston for diesel engines using spheroidal graphite cast iron!

We offer "spheroidal graphite cast iron pistons" that can withstand high cylinder pressures of over 20 MPa. These pistons utilize our unique mold casting technology, achieving improved thermal and mechanical strength compared to aluminum pistons. Additionally, they are more cost-effective than forged steel pistons. 【Benefits】 ■ Compatible with high cylinder pressures over 20 MPa ■ Excellent thermal load performance ■ Heat insulation effect due to the low thermal conductivity of cast iron ■ Superior tribological properties (lubrication, friction resistance) due to the graphite contained in the metal structure compared to steel pistons ■ Improved wear resistance is also possible with gas soft nitriding treatment *For more details, please download the PDF or contact us.

Aluminum cutting processing, brake master cylinder piston (aluminum), etc.

Aluminum cutting processing, brake master cylinder piston (aluminum), etc.

We accommodate various materials from aluminum bar stock to aluminum die casting!

Nisshin Seiki Co., Ltd.'s "Aluminum Cutting Processing" accommodates various materials from aluminum bar stock to aluminum die casting. By using single-purpose machines and NC lathes, we achieve cost-effective and high-performance processing. Additionally, by utilizing tools developed uniquely by Nisshin Seiki, we can consistently maintain high precision in inner diameters. Typical processing examples include spool valves, brake pistons, and sleeves for automatic transmissions. The brake master cylinder piston (aluminum) is a crucial component that converts the force applied to the brake pedal into hydraulic pressure. Due to its soft aluminum material, we take great care to avoid scratches during processing. For more details, please contact us or refer to our catalog.

Piston (hard turning processing)

Piston (hard turning processing)

The material is chromium-molybdenum steel SCM415! It has undergone carburizing and quenching, achieving a hardness of over HRC60!

The process of performing grinding-level machining through turning is called "hard turning." Pistons used in hydraulic systems for construction machinery require extremely high precision, with outer and inner diameter tolerances of ±2 microns, surface roughness of Ra0.4 microns, coaxiality of inner and outer diameters of 3 microns, and perpendicularity between the end face and outer diameter of 3 microns as the required specifications. At our company, after heat treatment, we simultaneously machine the outer diameter, inner diameter, and both end faces using NC lathes, achieving machining equivalent to grinding through turning. By consolidating four processes into one, we enable process shortening and cost reduction. Additionally, simultaneous machining allows us to guarantee the coaxiality of the outer and inner diameters and the perpendicularity to the end face. We have a shipping record of 10,000 units per month and can accommodate orders of up to 100,000 units. *For more details, please refer to the PDF document or feel free to contact us.
