CNC Machining Process for Pistons

As a leading CNC Machining service provider, EMAR specializes in precision manufacturing of piston components for various industrial applications. Our advanced piston machining process combines cutting-edge technology with rigorous quality control to deliver components that meet the most demanding specifications.

The Critical Role of CNC in Piston Manufacturing

Pistons require extreme dimensional accuracy and surface finish quality to function properly in engines and hydraulic systems. Our 5-axis CNC machines achieve tolerances within ±.005mm, ensuring perfect cylindrical geometry and optimal ring groove dimensions.

Key Stages of Our CNC Piston Machining Process

1. Material Selection: We work with high-grade aluminum alloys (4032, 2618) and steel alloys depending on application requirements.
2. Rough Machining: Initial shaping with high-speed milling to remove bulk material efficiently.
3. Precision Finishing: Critical features like skirt profiles and pin bores are machined using diamond-tipped tools.
4. Surface Treatment: Optional anodizing or thermal spraying for enhanced wear resistance.
