PMK Liner Cut OD machines are precision CNC grinders developed for outer-diameter (OD) machining of liners, sleeves, and cylindrical components. The system ensures uniform wall thickness, precise geometry, and consistent surface finish.

These machines deliver exceptional roundness and surface finish through high-speed precision spindles and rigid mechanical alignment systems, with optimized feeds and automation compatibility for batch production.

Key benefits

• Performance: optimized for OD finishing with micron-level accuracy.
• Precision: fine feed system ensures consistent diameter control.
• Rigidity: stable base and spindle system for smooth cutting action.
• Productivity: quick setup and high repeatability for batch production.
• Minimal material deformation during fine finishing.

Applications

• Engine cylinder liners and sleeves.
• Hydraulic and pneumatic cylinder machining.
• Outer diameter finishing of bearing rings and liners.
• Automotive, compressor, and pump part finishing.
