ATRUMP OL-1220 CNC LATHE

Technical Description

This 2-axis CNC lathe is a compact horizontal turning center designed for precision machining of small to medium-sized components. Equipped with a CENTROID T400 CNC control system, the machine operates on dual linear axes—the X-axis controlling radial diameter adjustments and the Z-axis managing longitudinal workpiece positioning. The lathe features a maximum spindle speed of 4,000 RPM, providing versatility for various material types and cutting operations. With a swing capacity of 12.6 inches over the bed, the machine accommodates components up to this diameter, while the 20-inch machining length supports extended workpieces. The integrated tailstock enables between-center work, expanding application possibilities for longer parts and improving rigidity during heavy cutting operations. Powered by a 3.7 kW spindle motor, the machine delivers adequate torque for productive material removal. The CENTROID T400 control system provides ISO code programming with keyboard input, power-off protection, and comprehensive self-diagnosis functions. Servo motor-driven axes utilize precision ball screws for accurate, repeatable positioning. At 1,720 pounds, the machine maintains a manageable footprint suitable for job shops, toolrooms, and small manufacturing cells. This configuration is ideal for simple to moderately complex symmetrical parts, including shafts, bushings, and turned components requiring tight tolerances and consistent repeatability in high-volume production environments.
