The abrasive mop wheel‘s construction makes it perfect for achieving a smooth surface finish.
The abrasive mop wheel achieves a significantly smoother surface finish com- pared to that of a belt grinder. When choosing a grit size please select a grit size that is 2-3 sizes rougher than that used with a belt grinder.
Selection of the correct mop diameter
To be able to work at the optimal cutting rate (38-42 m/s) the selection of the abrasive mop diameter for machines, that are not equipped with RPM setting functionality, is based on the set RPM.
Machines that are equipped with RPM setting functionality are to be set according to the abrasive mop wheel diameter settings.
Attention! Before turning the machine on please check that the pre-set RPM does not exceed the maximum abrasive mop RPM setting.
Please refer to the adjoining table for the correct abrasive mop diameter settings for the optimal RPM range.
If the abrasive mop wheel is used at the optimal RPM setting, the grinding flaps stand up straight as result of the centrifugal forces around the core and provide optimum abrasive mop wheel grinding properties. Only the edges of the grinding flaps are subjected to wear and tear. This results in the use of new and sharper grits. This ensures uniform stock removal and surface finish – from the first to the last work piece.
Suboptimal RPM settings (too low) result in the incorrect positioning of the grinding flap as a result of tool / grinding pressure. This results in wear and tear on the grit side of the grinding flaps, and the area the abrasive mop wheel grinds is too large, which in turn results in higher friction between the workpiece and the grinding flaps. Consequently the workpiece and abrasive mop wheel are subjected to a higher thermal load and a higher degree of wear and tear on the grinding flaps.
Ultimately, this can result in the failure of the abrasive mop wheel and damaged grinding flaps.
Klingspor SM 611 abrasive mop wheels are certified for widths of ≤ 100 mm and maximum revolutions per minute of 50 m/s.
Optimal cutting rate: The abrasive mop wheel’s optimum performance range is a cutting rate between 38-42 m/s.

Factors influencing the grinding result
The surface finish is dependent upon a wide range of process parameters. The table below illustrates the different influencing factors and their affect on the grinding result.
Tool / grinding pressure
* Note: the essential parameters that affect the stock removal rate is the selection of a rougher (more stock removal) or finer (less stock removal) grit.
