1. It is high technology product first invented domestically by KEDA at the end of 2007.It is mainly used for granite、microcrystal and compound quartz slab calibrating.
2. The machine uses rough grinding head that has reasonable structure and high efficiency, which is a breakthrough for long time of low calibrating efficiency; it also reduces abrasive consumption that cut down the cost.
3. Cycloid pin-wheel reducer for speed regulating，position meter for lift displacement，the head lift height can be controlled precisely，that ensure calibrating correctly with high efficiency.
