Heavy Duty CNC Railway Underfloor Wheel Lathe
Lathe Introduction This lathe is mainly used for flange,tread and inner surface of wheel set with 1520 wheel distance.The wheels have to be disassembled to fix wheel flange and tread. It is composed of bed,headstock,CNC tool rest,lifting jack,hydraulic system,electrical system and lubrication system.CNC system is SIEMENS 828D(or customize).Feeding system is driven by AC servo motor. Main Characteristics Main Parameters of Underfloor Wheel Lathe The lathe adopts separate transmission.Left and right chucks drive the wheel set at the same time.There`re two set arc claw on each chuck to clamp the wheel set. Longitudinal and transverse travel of left and right tool rest is driven by AC servo motor.Automatic operating can be realized by inputting diameter of wheel set and other parameters. Tool rests are from Sweden Sandvik,high quality and low cost.When processing inner surface of the wheel set,tool should be changed into end surface tool. This lathe is one of our mature products.Design,manufacture and material satisfy relative standards.Product quality is controlled by ISO 9001-2000 quality system. This lathe has functions such as programming of wheel outline curve,processing,memorizing invoking and display. CNC tool rest is equipped with auto~tool setting and measuring device.Automatically achieve the longitudinal and transverse positioning of tools. Main Parameters
