JP20A/25A/28A Single-shaft Grinding Polisher
Mainly used for the grinding and polishing of large plane and large spherical mirrors, as wellas the precision grinding and polishing of metal or non-metal moulds.
Spindle speed, swing shelf swing times can be adjusted according to the needs of machining parts separately frequency conversion, and the pressure of the swing shelf should be controlled by pneumatic pressure or be adjusted by using the balancing weight. (Optional touch screen and knob for operation)
