Proven Stability & Economy for Every Job Shop
The Qingluan CK6140 Flat Bed CNC Lathe is the world’s most trusted configuration for small-to-medium batch manufacturing, toolroom prototyping, maintenance repair operations (MRO), and technical training facilities. Built upon a heavily ribbed one-piece cast iron bed with supersonic induction-hardened and ground guide rails, the CK6140 offers rock-solid cutting stability at an unbeatable investment cost.
Core Technical Advantages
- High-Hardness Supersonic Frequency Quenched Bed: The bed guide surfaces achieve a hardness of HRC 52–55 and are precision hand-scraped and ground to ensure ultra-low frictional resistance and decades of wear resistance without accuracy loss.
- Independent High-Precision Spindle Structure: Balanced three-point bearing support utilizing NSK precision bearings guarantees smooth, low-vibration operation across the full 150–2,500 RPM speed range, ensuring excellent roundness and surface finishes on stepped shafts, internal bores, and tapers.
- Comprehensive Thread Cutting Capability: Flexible electronic gearing cuts metric, imperial (inch), module, and diametral pitch threads with precise start/stop synchronization, eliminating thread damage and pitch errors.
