MORI SEIKI SL-403B/800 CNC LATHES

Technical Description

This CNC lathe features a robust 15" chuck with a maximum spindle speed of 2,400 RPM and a swing capacity of 39", allowing machining diameters up to 27.9" over the bed. It accommodates bar stock up to 4.25" diameter through a 4.5" spindle bore with an A2-11 spindle nose, providing substantial bar capacity for varied turning operations. The machine offers a machining length of 44" with a single spindle and a single turret holding 12 total tool positions, enabling versatile tooling configurations. Axis travels include 13.7" on the X-axis and 36" on the Z-axis, with rapid traverse rates of 787 IPM and 944 IPM respectively, ensuring efficient positioning and reduced cycle times. Notably, the lathe operates without a tailstock, emphasizing its use for longer or heavier workpieces supported by the chuck and steady rest if necessary. Control functions are managed via the Mori MSG-501 CNC control system, known for precise and reliable machining performance. This setup is ideal for medium to large part manufacturing where flexibility in tooling and moderate spindle speeds are required, making it suitable for applications such as automotive, aerospace, and general precision engineering.
