High-Precision Cylinder Liner Cutting Machine

A high-efficiency, high-precision automated cutting machine specially designed for the engine cylinder liner manufacturing and remanufacturing industry. Utilizing advanced cold-cutting technology, it completely replaces traditional sawing and flame-cutting methods, effectively eliminating issues such as burrs, deformation, heat-affected zones, and dimensional inaccuracies. This ensures a flawless end face on cylinder liners, significantly enhancing downstream machining efficiency and final product quality.

Scope of Application

  • Cast iron cylinder liners, steel cylinder liners, alloy cast iron cylinder liners
  • Wet cylinder liners, dry cylinder liners
  • Fixed-length cutting for new cylinder liners
  • Cylinder blocks of various engines such as automotive, marine, construction machinery, generator sets, etc.

Core Advantages

✅ Burrs-free and Zero Deformation

Utilizes high-speed cold cutting with hard alloy tools, resulting in a smooth and flat cut surface without extrusion burrs or heat-affected zones. No need for secondary deburring, it can directly proceed to the honing process.

✅ Ultra-high Precision

Repeatability positioning accuracy reaches ±0.02mm, with controllable length tolerances, ensuring each cylinder liner's dimensions are highly consistent, meeting precise assembly requirements.

✅ High Efficiency and Energy Saving

Single piece cutting time only takes 10—30 seconds, with efficiency being 3—5 times higher than traditional saw machines, and energy consumption reduced by over 60%.

✅ Easy Operation, Intelligent Control

Equipped with a Human-Machine Interface (HMI), multiple cylinder liner specification parameters can be preset. One-button start automatically completes clamping, feeding, cutting, and tool retracting. Ordinary workers can operate after simple training.

✅ Durable and Easy Maintenance

The whole machine is made of steel structure, with key components optimized through finite element analysis for strong anti-vibration. Modular design makes maintenance and repair convenient.
