Product Description

The CK6140 Flat Bed CNC Lathe is engineered for precision and power, delivering robust performance for medium to heavy-duty turning operations. Featuring a maximum swing over bed of φ400mm and a machining length of up to 2000mm, this machine is ideal for complex, long-part production in automotive, aerospace, and machinery manufacturing industries.

Equipped with a high-capacity spindle offering optional bore sizes of φ52mm or φ70mm, the lathe supports a wide range of workpiece diameters. The spindle features a stepless frequency-converted drive system that enables speed control across 60 to 1600 RPM for superior adaptability across material types and cutting conditions.

Its precision feed system delivers X-axis and Z-axis positioning accuracy to within 0.001mm, ensuring consistent and high-quality machining. A rapid traverse rate of 6 m/min (X-axis) and 10 m/min (Z-axis) improves cycle times, while the 4-position (or optional 6-position) tool turret with 25×25mm tool capacity enhances operational efficiency.

The CK6140’s tailstock features a φ65mm sleeve with an MT4 taper and 130mm travel, making it suitable for deep-hole drilling and shaft work. Backed by a rigorous quality control process—including 48+ hours of continuous testing, laser interferometry, and circular interpolation verification—each lathe is built for long-term performance and easy maintenance with full production records.
