Grinding tooling encompassing everything from tools used to aggressively rip up coatings to finely polish concrete and stone. Grinding tooling comes in a variety of shapes and sizes to suit different machines. In general cup wheels are used on hand grinders and grinding shoes are used on floor grinders. There are a number of factors that are universal when assessing what grinding tooling is required.
The matrix that holds the diamonds in place must wear away fast enough to expose new diamond but not too quickly or the diamonds will fall out before they are completely used.
As a general rule:
Hard material = Soft Bond
Soft material = Hard Bond
All else being equal a softer bonded tool will cut faster than a harder bonded tool, however a softer bonded tool will also wear away faster than a harder bonded tool.
We offer out grinding tooling in 5 bonds; Super Soft, Soft, Medium, Hard and Extra Hard
All else being equal a grinding tool with fewer segments will cut faster than the same tool with more segments, however the tool with fewer segments will wear away faster. It is important to consider the weight of the machine you are using and the effect you are trying to have on the material. The more grind pressure you are able to exert on the surface, the more aggressive the cut will be. An easy way to think of grind pressure is using this formula – Grind Pressure = weight / number of segments
All else being equal the more vertices (points) a segment has, the more aggressively it will cut. This is particularly evident when it comes to coating and glue removal. Tooling with few vertices, such as the coffin segment, will struggle to cut through coatings and are more likely to get clogged. However, the coffin shaped segment will produce a much finer honed finish.
The grit size is specified in US mesh sizes according to the aperture size of the sieve that is used in the sorting process. The lower the grit the more aggressive the segment will be. We offer grinding tooling in 5 grits; 6, 16, 30, 60 and 120. Grits 6, 16 and 30 are primarily used for floor preparation and aggressive material removal. Grits 60 and 120 are used when polishing or honing concrete.
