HW-G5/G7 220/380V Square Plates Concrete Grinder

New HW-G5/G7 doesn’t leave trace on floor. The old products usually leaves trace on floor, this is because the disc plates don’t cross very well, which is not seen in coarse grinding, but in finish grinding.

HONWAY grinding and polishing machine with the square plate is a good solution to break up the deposits of grease, dirt and industrial contaminants, and to level up the uneven surface, Square plate series is suitable for preheat and level the concrete surface before epoxy coating.

HW-G5, 10hp, grinding width 600mm, 4 grinding plates, 12 pieces of diamond tool. With the magnetic disk and Velcro, It is very easy and shift to change diamond tool. The design of square disc plate could 100% touch wall and grind corner.  HONWAY square plates would not leave trace on floor,  as I know some machines like HW-G5 usually leaves trace on floor,  which is caused by the design problem, as the disc plate can’t cross very well. HW-G5 would have not this problem.

HW-G7, 15hp, grinding with 700mm, 4 grinding plates, 12 pieces of diamond tools. HW-G7 has the quickest motor speed, from 300 to 1800rpm, so it is most powerful machine in HONWAY grinding and polishing equipment, it is good for grinding and polishing in large area, and greatly consume time and labor.

Application

For coarse grinding, medium grinding, fine polishing, crystallizing, preparation, maintenance of all kinds of floor;

Remove painting, coating, epoxy, urethane, glue, polyurethane, mastic with PCD tools on all kinds of floor.

HW-G5/G7 has 4 heads square plate has 12 diamond pad, very suitable for floor preparation-leveling floor before epoxy resin. Gear box is made totally by aluminum alloy, very durable and reliable.  It is easier and more comfort to operate than counter rotating machine. The month of water tank is especially made,  much super than old design to prevent the water leakage when pour water.  The working way can do forward and backward.

HW-G5/G7 concrete grinder general introduction

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

HW-G5/G7 concrete floor grinder machines have the key features: the gear box is the soul of the concrete floor grinder.

 

 

 

 

 

 

 

 

 

The quality and performance of floor grinding machine 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.

 

 

 

 

 

 

 

 

 

 

 

how to prevent the problem of oil leak?
Oil leak of the gear box is a very troublesome problem for contractors, but it is also a unavoidable problem. The rotation of gears causes high temperature and high pressure inside the gear box, the oil insides will penetrate to outside to release the pressure.
leak oil from sides,leak oil from shafts, leak oil from seals
Oil leak is also related with the gearbox: its design on leak oil, manufacture, porcess, etc, even with the assembly.
HONWAY 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 machine? No, they protect human beings

Concrete 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 electrical suppliers not only provides products, but also participate in the design of HONWAY electrical system, for the safety of human beings and machine.

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.

 Sunye 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.
