(For < Size 15) CNC Linear Guideway Grinding Machine

JL-20200CNC, JL-20400CNC

Adopting a double-column structure, the main structure is cast from high-grade FC30 cast iron material, ensuring excellent structural rigidity while effectively reducing thermal effects. This design allows the machine to maintain stable precision during prolonged operations.

The worktable employs a hydraulic control system and is equipped with a diamond roller dresser, allowing simultaneous grinding of both sides and the track surface of the linear guide.

Features

  • Hydraulic Control System: Ensure high precision motion control and real-time adjustment flexibility. Helps maintain machining accuracy.
  • Double Column Structure: Possessing superior structural rigidity and reducing thermal effects ensures that the machine maintains extreme stability in precision during prolonged operation.
  • High Structural Rigidity: Cast with advanced FC30 cast iron material, the machine exhibits superior stability.

Application

  • Suitable for workpieces of size 15 and below.
