SUNMASTER CHC-2240 CNC LATHES

Technical Description

This CNC lathe features a 21.65-inch swing, allowing the machining of parts up to that diameter over the bed. It supports a maximum turning diameter of 12.8 inches, making it suitable for medium-sized cylindrical workpieces. The machining length is 34.25 inches, defining the maximum length of the workpiece that can be turned between centers or with the tailstock support. The bar capacity is 3.07 inches, enabling the feeding of raw material bars of this diameter for bar-feed operations. Powered by a 14.75 hp motor, this lathe delivers sufficient cutting force for a broad range of machining tasks, with a maximum spindle speed of 3,500 RPM for efficient turning and surface finish. It operates on a 2-axis CNC control system, typically controlling movement along the X (cross) and Z (longitudinal) axes, suitable for standard turning and facing operations. The inclusion of a tailstock enhances workpiece support for longer shafts and drilling operations, improving accuracy and reducing deflection. The CNC control ensures precise, repeatable, and automated machining processes, optimizing productivity and part consistency. This combination of moderate swing, substantial machining length, robust power, and CNC control makes the lathe versatile for manufacturing components in automotive, aerospace, and general engineering sectors.
