YK7640 CNC GEAR GRINDING MACHINE

Features of machine

1.    Machine adopts modular design with consideration of factors such as  thermal equilibrium, temperature influence, the structure optimization to obtain the best performance.

2.    In adoption of  REXROTH IndraMotion MTX micro system to realize stable & reliable performance. Grinding spindle is driven by powerful built-in motor with max power 15 kw to achieve 60m/sec of cutting speed.

3.    Work table is driven by high precision worms delivering  high rigidity and precision,table is also designed with dampen mechanism

4.    Axial cutting tool movement combined with wider grinding wheel enable to dress upto 20 kinds of wheel shape at one time so that the frenquency of wheel dressing and wheel changeover could be greatly reduced for higher productivity.

5. Closed circuit control together with feartured dressing unit to be able to perform any contour of  wheel dressing.

6. Built-in temperature sensor  combined with special software to keep good consistancy of accurancy

7. Applying of infinite element anlyasis to achieve high stability of machine structure ,all base castings are of  high performance heat treated gray iron to obtain good rigidity and reliability. state-of-art wheel spindle design for high speed grinding

8. Special interface with manual input for easy operation, combinations of parameters are preset for selection, signal status could be easily checked on operation panel for convenient maintainence.

9. Available of online remote diagonosis function

10. Machine is designed to fit wide range of applications,mostly favorable in grinding internal cycloid wheel within specification of  No.7, spur gear grinding could be realized after changing of special profile grinding software.

11.  Compact design for easy installation at a samll floor space,machine is of high rigidity fit to small and large batch production

12.  complete enclosure of machine

13.  Simple and compact enclosure design with built-in hydraulic and piping system
