What is a planetary grinder?

 

The base of a planetary grinder consists of a large main disc (the round gear box). 

Three or four smaller discs mount to the main disc, and these smaller discs turn at a different speed than the main disc. 

The smaller discs all lie along the same plane and make contact with the floor simultaneously, while the larger main disc lies on a different plane and does not make contact with the floor.

 

What's the advantage of JS planetary floor grinder?

 

Double layer gear, no belt

Aluminum integral casting gear box

Quick-change magnetic tooling systems

Variable-speed soft start

Both grinding and polishing, both wet and dry

Be good at high gloss and smooth surface polishing

 

Gear-driven forced planetary drive provides durability and flexibility of equipment. 

The double layer gear systems drive the grinding plates, large main disc (gear box) runs at 0-300 RPM, smaller discs run at 0-1800 RPM.

Planetary grinder can be used for all grinding and polishing applications (wet or dry), adhesives and coating removal, surface repair and flattening of concrete, terrazzo, etc.

1. Initial grinding with metal diamond #16 or #30, depends on the floor hardness.
2. Fine grinding with metal diamond #80, #150, #300 in steps.
3. Polish the floor with resin polishing pads #50, to repair the polishing scratch of metal diamonds.
4. Spray the hardener, keep the ground moist for 2 hours. If the floor absorbs the hardener quickly, please spray again.
5. Fine polishing the floor with resin polishing pads #150, #300, #500.
6. Super fine polishing with resin polishing pads #1000, #2000, #3000.
7. Spray the polishing cream after the super fine polishing #1000-3000. Apply the polishing cream with a heavy-duty brush broom, so the floor will be covered with the liquid evenly. The thinner the better.
After the polishing cream dry, use C8 high speed burnisher and DT021 black buffing pads to finish final polishing.
