CNC FLOOR-TYPE CENTRE LATHE BASIC PARAMETERS 4-guideways bed Max. torque on spindle Max. weight carried between centres Turning length In its basic version the TZL 420 horizontal centre lathe – thanks to the innovative mechanical solutions and advanced control systems – is a multi-purpose lathe that guarantees productive rough and finish machining. PURPOSE The TZL 420 CNC lathe is designed for workpiece machining in the range of turning in accordance with the machine tool specifications, especially machining of large-size shafts and large-diameter workpieces. When delivered with special equipment it can operate as horizontal machining centre with turning, drilling and milling capabilities. It can be equipped with an automatic tool head, tool and workpiece measuring systems, controlled C axis, workpiece steady rests. CONTROL SYSTEM The application of the state-of-the-art CNC system allows for automatic, precise and productive workpiece machining according to a program. GRUPA RAFAMET
