Why Choose Our CNC Solutions

Key Features

  • Mega-Size Worktable (Ø2200mm): Accommodates large components up to Ø2400mm in rotation range, such as wind turbine flanges, generator housings, and reactor seals.
  • Vertical Grinding Structure with Ultra-Rigid Frame: Gravity-assisted layout minimizes part deformation, ideal for flatness and concentricity control in massive parts.
  • Multi-Axis CNC System: Supports face, OD, ID, taper, and chamfer grinding in one setup, reducing time and clamping errors.
  • Heavy-Duty Grinding Wheel (Ø500–600mm): Ensures deep cut capability, consistent pressure, and long dressing cycles even on hard alloys or large surfaces.
  • High Torque, Servo-Controlled Rotary Table: Maintains rotational stability under high part weights and speeds.
