Although there are many kinds of plane grinding machinery, they have different advantages and disadvantages, and most disadvantages are that grinding disc can become deformed and uneven naturally, and the service life of motor and drive mechanism cannot reach the budget.

PZM850 Plane Vibration Grinder of the latest design has following advantages:

1. The material of grinding disc is HT150 cast iron. When grinding, the grinding sand grains will be extruded into the dispersed shrinkage of cast iron, which makes the formation of silicon carbide grinding surface on the surface of grinding disc, thus the machine doesn't change its grinding disc throughout its service life.

2. Producing vibration mechanism adopts polyurethane block, with amplitude equalization, thus vibration and jump of workpieces will not occur.

3. Drive mechanism adopts vinylon connection block as couping, with 100% transmission efficiency, and does not have impact on the service life of motor.

Repair is not required by PZM850 plane vibration grinder under continuous operation for 7700 hours, and the machine enjoys free maintenance within three years.

Processing scope:

It can be used in grinding of plane, conocave plane, raised plane and all kinds of plastics, rubber molds, blades, valve seat of compressor valves, valve block, PEEK valve block and plain sealing elements of valves. The maximum diameter in grinding is 650mm, with a thinnest thickness of 0.2mm for workpieces. Different materials can be ground by changing corresponding abradant materials, the highest precision can reach 0.002 with flatness optical measuring of Level 0.
