How to distinguish the quality of the floor grinder?

The floor grinder is mainly used for related construction work on the ground. It can effectively grind terrazzo, epoxy mortar layer and concrete surface, etc., to make the floor more flat, smooth and clear. Compared with the previous manual grinding of the floor, the time cost is greatly reduced, the work efficiency is improved, and the grinding effect of the floor is also obvious.
So how to distinguish the quality of the floor grinder? What brand do you recommend buying? We analyze from the following aspects:

Efficiency and durability are the key to buying a floor grinder. There are four main factors that determine efficiency:
1. Grinding area
2. Machine weight
3. Motor power
4. Whether the gearbox is integrated or split.

The integrated gearbox generally adopts one-stage gear transmission, which means that the output of the motor can be transmitted to the grinding disc to the maximum extent.
In addition, it depends on the after-sales service. No matter how good the manufacturer is, they can’t guarantee that all equipment will not have problems during use. Once there is a problem, if the after-sales service fails, they will often return to the factory for repairs, not to mention whether there are maintenance costs and round-trip fees. How much, just a few days of delay in work will not be enough for workers to eat, live and pay, and the construction period will be delayed, so after-sales must be in place.
On the premise of efficient and durable after-sales service, we need to look at other configurations, such as:
1. Can the frequency be converted
2. Whether the motor is iron shell or aluminum shell
3. Whether the motor has overload protection and over temperature protection
4. What are the dust prevention measures?
5. How many oil seals are there in the gearbox?
6. Whether there will be oil leakage
7. Is the counterweight iron integrated and adjustable?
