φ4000mm Swing · 0.5–106 rpm Spindle · High Torque

The CK61 Series is a heavy duty cnc lathe machine designed for machining extra-large and ultra-heavy components with exceptional precision and rigidity. Featuring a swing diameter over tool carriage of up to Ø4000mm, a stepless spindle speed range of 0.5–106 rpm, and high-speed axis traverses, it excels in slow-speed torque-driven heavy cutting—making it ideal for wind turbine hubs, marine shafts, industrial rollers, and metal processing cylinders.

Why Choose Our CNC Solutions

Key Features

  • Ultra-Large Swing Diameter (φ4000mm): Accommodates massive parts such as large steel rollers, impellers, and circular structural components.
  • High-Torque Spindle (0.5–106 rpm): Stepless speed control allows precise low-speed heavy-duty cutting of high-resistance materials.
  • Wide-Area Rapid Traverse (X: 2500mm/min / Z: 3000mm/min): Enables efficient tool positioning and fast rough-to-finish operations on long workpieces.
  • Stable Structure for Large Loads: The rigid box-type bed and large-span guideway system ensure outstanding vibration damping.
  • Optional Tailstock or Steady Rest: Supports long shafts and irregular heavy parts to maintain axial stability.
