CK84100S

DESCRIPTION

The Uses and general introduction 1.The machine is special-purpose machine for machining wheel sets profiles, journals and inside of locomotives ,and gauge of which is 1435mm. It is suitable for manufacturing and repairing factory of railway and transport department concerted，The machine can meet turning of wheel set profiles, journals, and meet related standard of Ministry of Railway. 2.CNC Wheel lathe consists of lathe bed、left/right headstock、left/right tool carriage（include tool-setting measuring device）、jack、hydraulic system、electrical control system、lubrication system etc. Main drive can be driven by two AC frequency conversion motors, and spindle realize stepless speed change within 7.5～42r/min by precision planetary gear reducer. Machine CNC System adopt SIEMENS 828D（other CNC Systems are available on the request of customer），feed system is driven by servo motor.
