Concrete grinding cup wheels is a kind of metal bond sintered diamond grinding tool, which is used for rough grinding of cement and terrazzo floor. With fast grinding speed and high efficiency, concrete grinding cup wheel is usually used on hand-held grinders or walk-behind floor grinders to grind or polish green concrete floor or refurbish old concrete floors.
Technology features of concrete grinding cup wheels:
There are two main sintered technologies for concrete grinding cup wheel: cold pressed and hot pressed.
The cold pressed sintering pressure is big and the sintering time is long.
Generally, overall cold pressed sintered is applied. The segments with hot pressed sintered are welded on the base by high frequency welding technology.
Also, there is welding technology for concrete grinding cup wheel.
For base, there are steel base and aluminum base.
