CK6163BT Heavy-Duty CNC Lathe: Precision Turning for Large Workpieces with Enhanced Stability

The CK6163BT Heavy-Duty CNC Lathe is engineered to deliver exceptional performance in machining large and complex workpieces, combining robust construction with high precision. With a maximum swing diameter over the bed of 630mm and a swing diameter over the cross slide of 410mm, it accommodates oversized components that demand stability during turning operations. The X-axis (transverse) travel of 420mm and a distance between two centers of 1000/1500mm provide ample space for processing both short and long workpieces, making it versatile for diverse industrial applications.
Equipped with an independent spindle unit featuring stepless speed change, the lathe offers flexible speed adjustment to suit various materials and cutting requirements. The A2-8/D8 spindle model, boasting a large φ105mm spindle bore and Metric No. 120 inner taper, ensures secure clamping and efficient power transmission. Its speed ranges—low (12-100 rpm), medium (70-300 rpm), and high (260-1200 rpm)—enable optimal cutting parameters for tasks ranging from heavy-duty roughing to precision finishing.
The lathe’s stability is enhanced by a 400mm-wide double-triangle guideway and an integrated machine foot, minimizing vibration and ensuring consistent performance even under high loads. Powered by a 7.5/11kw spindle motor, it delivers reliable power for demanding machining processes. Standard features include a manual 250mm three-jaw chuck for secure workpiece clamping and a turret with vertical 4 positions/horizontal 6 positions for quick tool changes, improving operational efficiency.
Precision is a hallmark of the CK6163BT, with repeat positioning accuracy of X-axis ≤ 0.01mm and Z-axis ≤ 0.015mm, roundness <0.007, and working accuracy of diameter consistency <0.03mm over 300mm length. Additional features such as a lengthened and thickened slide, adjustable front pressure plate gib, and automatic oil lubrication further enhance rigidity and cutting stability. Ideal for industries such as energy, aerospace, and heavy machinery, the CK6163BT excels in handling large-scale, high-precision turning tasks with reliability and efficiency.
