Product Description
The CK40-1000 Slant Bed CNC Lathe is a high-performance machine designed for turning medium- to large-sized workpieces requiring longer machining lengths. Its 30° slant-bed design ensures optimal chip flow and improved structural rigidity, making it suitable for demanding machining environments in automotive, aerospace, and mechanical manufacturing industries.
This model features a 4000 RPM high-speed spindle driven by a 7.5 kW motor, with a spindle bore of Φ65mm and equipped with an 8-inch hydraulic chuck capable of handling bar stock up to Φ48mm. It supports a maximum machining diameter of Φ400mm and a machining length of 900mm, offering flexibility across various component types.
The use of precision linear guideways ensures rapid feed rates of 20 m/min on both X and Z axes, contributing to higher productivity and reduced cycle times. The tailstock features manual movement with a long 800mm travel range and a 120mm hydraulic/manual sleeve stroke, providing reliable support for long workpieces.
All CK series machines undergo stringent quality control, including over 48 hours of continuous operational testing and advanced diagnostics such as laser interferometry and circular testing. Every machine is backed by a complete traceability record, ensuring superior after-sales service and efficient spare part supply.
