HW-G8 220V 380V planetary head concrete grinder polisher machines is driven by gears, planetary design. The planetary gearbox has three grinding disc. The gearbox and the three grinding disc rotate towards converse direction like a satellite or planetary, which gives more pressure on the three grinding disc, so it works more powerfully and effectively.HW-G8 220V 380V planetary head concrete grinder polisher general introduction
HW-G8 220V 380V planetary head concrete grinder polisher have the key features: the gear box is the soul of the concrete floor grinder.
The quality and performance of diamond floor grinder depends mainly on the gear box. We could say the gear box is the soul of the machine. The quality of gearbox is closely related with many factors: design, material, process, assembly, etc. HONWAY has a team of experienced gear engineers and processing workers, who participate on the improvement and quality control of gear box.

Oil leak is also related with the gearbox: its design on leak oil, manufacture, porcess, etc, even with the assembly.
HONWAY concrete surface grinder gear box, gears, shafts, and sleeves are precisely proceed and the tolerance is controlled carefully, for make sure the gap is very tiny.

Double seal design: around the output axis, two seals are put, for block oil. Good quality on seal and O ring-heat resistant, wear resistant. for example, the seals is TTO brand, which is from Taiwan enterprise.
Good quality on seal and O ring-heat resistant, wear resistant. for example, the seals is TTO brand, which is from Taiwan enterprise.

What the electrical elements protect? the concrete surface grinder machine? No, they protect human beings

diamond floor grinder needs people to operate very closely, and by hands, so the eletrical elements are extremely important for the safety of human beings. In actual grinding floor, the electrical conditions are very complex: overload, under-voltage, exceed current and so on, which threaten the safety.
HONWAY use pure copper motor, sunye inverter, IP67 industrial plugs. Motor factory is an old one with 50 years, and only uses pure copper as the material. The motor is built-in overload protection, leakage protection, phase loss protection.

inverter, one of top ten low-voltage inverters bands in China, is involved in the design of HONWAY high-performance current vector inverter.

IP67 industrial plugs, water proof grade, no problem for wet grinding environment. The wires are thick enough to afford big electrical current.

Brief introduction:

HW-G8 concrete grinder polisher is large size among the planetary gear structure series, the grinding width 750mm with 3 pieces of grinding disc, 15hp motor, 18.5hp inverter (220V), variable motor speed 300-1800rpm.

It is driven by planetary gear design. It is an versatile grinder suitable for many different applications.

The best walk behind dustless concrete floor grinder can be used for grinding and polishing many kinds of floors such as concrete, garage floor, commercial floor, Industrial floor, natural stone, .

Compared to non planetary concrete grinder, the planetary grinder is more powerful and effective, maximizing overall production hours and minimizing maintenance time.

Selection of the abrasives

There are two kinds of attachment for metal grinding pads for walk behind concrete grinder :

one is screws and magnet; one is Redi-lock.

Attachment for diamond resin polishing pads: by velcro, 9 pcs of switch plates are offered.

Honway supplies the diamond pads specifically designed for Honway machinery when grinding and polishing floors of concrete, terrazzo, marble and granite. Please contact us for suggestion the sizing of the diamond Pads.

Many contractors have trouble understanding how bonds work relative to different kinds of concrete.

If the bonding material used to hold the diamond is hard and the concrete is also hard, the bonding material cannot be consumed at a fixed rate, and the diamond cannot be exposed and effectively contact the concrete.

Therefore, hard concrete should be grinded with soft bond abrasives. Conversely, if soft concrete is grinded with soft bond, bonding material will be consumed too quickly.

Note: You must follow the proper grit sequence during concrete processing. For example, if you start with 30 grit, the next grit is 50 or 60, then 100 or 120, 200, 400, 800, etc. Skipping a grit step will seriously affect the result you get. Since Each grit is designed to remove the scratches of the previous grit.

Random accessories

2 pcs lifting rods, 1 pcs dust proof shroud, 9 pcs resin pad conversion disk, 1 iron weight.
