Main characteristics and functions of machine
1. Machine drive adopt separation drive,and wheel sets are driven by spindle
simultaneously. Two suits of arc claw bite wheel sets on each faceplate.
2. The longitudinal and lateral movement of tool carriage is driven by CNC methods. Automatic processing can be realized by inputting (manual operation) diameter and related parameter.
3.Tool carriage is equipped with Swedish SANDVIK special-purpose tools of railway,and it
can realize better result and lower the cost during machining. Facing tool should be
replaced while machining the inside of wheel sets.
4.Tool carrier equipped with special tools for machining and repairing inner brake disc of wheel sets.
5.The machine is equipped with special-purpose tooling for machining the wheel sets profiles, journals and inside of locomotives.
6.The machine is mature products of our company, manufacturing material meet the related safety,environmental standards of the State and Industry, and quality of products is controlled by the ISO9001-2000 Quality System. We guarantee to provide products with advanced technology,reliable performance,reasonable structure,safety,environmental protection to our customers.
7.The machine has functions of wheel outline curve programming,machining,memory,display, and also has functions of safety protection,preventing the false operation,alarm display.
