Key Engineering Advantages

  • ✓ Extra-wide 400 mm bedway width providing massive torsional rigidity during heavy roughing
  • ✓ Headstock features 3-speed manual gear shift with frequency-variable stepless spindle speeds for huge low-end torque
  • ✓ Dual V-way and flat-way combination delivering exceptional guidance accuracy under heavy cutting forces
  • ✓ Precision ball screws with central automatic cyclic lubrication manifold
  • ✓ Independent heavy-duty MT5 tailstock supporting long workpieces with optional pneumatic/hydraulic quill feed

Primary Industrial Applications

Medium-heavy machinery shafts, motor rotors, and agricultural axles
Oilfield drill pipe threading, API casing repairs, and coupling turning
Hydraulic cylinder tubes, piston rods, and large flange turning
Mining equipment roller pins and paper mill conveyor rollers

Engineering Overview

The Mainland CNC CK6150 is renowned for its unyielding mechanical toughness. Where light-duty lathes struggle with chatter during heavy cuts in 4140 or stainless steels, the CK6150’s 400 mm wide induction-hardened bedways absorb heavy cutting forces with total structural stability.

Geared Headstock High Torque

By combining a 3-step manual mechanical gearbox with a 7.5/11 kW frequency inverter or servo drive, the CK6150 delivers huge low-speed torque below 150 RPM, making it ideal for deep boring bar passes and coarse thread cutting in tough forgings.
