How to choose a floor grinding machine?
The most important part of floor grinding machine is gear box. If
the gears are good quality, if the gear would leak oil... these are
related with machinery technique, workcraft, and factory
management.
Honway gears are made by world top gear processing equipment
Reishauer. (The processing equipment decides the gear accuracy) The
gears grinding is seventh grade, which guarantees that the gears
are solid, still keeps flexibility, but not elastic. Gears'
accuracy and solidity make sure that gears drives precise like a
Rolex watch. (I come across a case that the gears of upper plate
are easily broken when the machine hits steel rebar under floor.
This is not the most bad situation, if the hit is violent, the
gears of upper plate are broken and the hit is transferred to the
gears of below plates, the gear box has to open and replace gears).
The thing which happens easily for the floor grinding machine is
the gear box leaks oil. Oil leak is very boresome, as floor will be
stained with oil. The gear box can't completely sealed, as it needs
to contain gears and be connected to grinding plates. So it has the
gas to leak oil. (This is why some America and European companies
use belt driven, not gears driven. But belt driven has some
disadvantages. So people makes gear driven machine). The only
solution now is to stem these gaps. It is not a easy job. It is
related with many factors as I told previously: gears, design,
worker's workcraft. Only a little negligence would cause problem.
For example, Honway once had the design of single seal, if the seal
needs to replace, the gear box has to open (all knows that gear box
is not easy to open). Now Honway had the design of double seal,if
oil seal gets old, or problems, just take out the grinding plates
and replace seals, which is easy to operate, and the customers
could do it in their floor site. Honway has solved many problems of
leak oil, which are not seen from the machine outlook. Honway knows
it well from the old customer's feedbabck, and always improve,
otherwise the customers will be lost.
The bearing insides are Japanese brand '' NSK'', not Chinese
bearing; the oil seal are TTO, a Taiwan brand. Why Honway adopt the
famous brand? even if the others brand also could use, and no
problem sometimes. The problem is: these spare parts are used, to
reduce the occur chances of problems.
The machine has a problem, it is the after sell service. Honway
made all parts are easy to disassembly and repair.
This year, the water tank is mirror stainless steel, three or four
times higher than iron tank and plastic tank. This kind of water
tank is only used in high grade machines.

They are many details about the floor grinding machine. Details
decides success and failure.
