AMERICAN TURNMASTER SBS-790-35 CNC LATHES

Technical Description

This is a CNC turning center engineered for heavy-duty production work, featuring a robust 50 HP spindle motor capable of delivering sustained cutting forces across a wide range of applications. The spindle operates at a maximum of 1200 RPM, making it particularly well-suited for large-diameter workpieces and interrupted cuts where lower speeds provide superior surface finish and tool life. The 35-inch swing over bed accommodates substantial components, enabling efficient machining of mid-to-large sized parts in a single setup. The CNC control system provides full automation and repeatability, eliminating manual operator input and enabling complex multi-axis machining cycles. This integration ensures precise dimensional accuracy and consistent part quality across production runs. The machine likely features a 2-speed gear-driven spindle arrangement, optimizing torque delivery across the operating range while maintaining efficiency. The combination of 50 HP and 1200 RPM generates approximately 209 foot-pounds of torque, enabling aggressive cutting parameters with rigid tooling. The substantial swing capacity indicates a machine designed for industrial production environments, likely equipped with box-way construction and anti-friction bearing surfaces for extended service life. Typical applications include CNC turning of shafts, bushings, flanges, and other cylindrical components in ferrous and non-ferrous materials. The specifications suggest compatibility with industrial chuck sizes ranging from 12 to 24 inches, providing flexibility for various workpiece geometries. This class of machine is commonly found in job shops, OEM suppliers, and dedicated production facilities requiring reliable, precise turning capabilities with minimal setup time.
