Technical Advantage
1.Have the natural frequency of each machine bed, so that avoid grinding resonate which makes the quality worse;Built-in synchronization work spindle and grinding spindle with high accuracy, high dynamic performance, large range of speed regulation and positioning control.
2.The speed can be adjusted 10~3000 RPM infinitely,driven without belt and easy installation and maintenance
3.Internal grinder adopts high frequency synchronous electric spindle with constant power,higher grinding efficiency of 30 ~ 40% is more than asynchronous high frequency electric spindle;
4.Loading and unloading cycle time is less than 1s;
5.High static and dynamic precision of slide, Straightness: 1.0 μ m/ total travel(80~250mm),Repeatability of linear displacement: 0.5μ m, Stiffness:3000N/μm
6.Linear servo motor used for dressing, can dress the single radius contour ,multi-radii contour , hyperbola and logarithmic contour.
7.Automatic conveyor system for the line with high efficiency and stable running.
