Crashing Rollers, if we exclude diamond rollers, can be built in HSS, high-alloy steels or carbide.
In any case, to ensure acceptable performance, hardness should be no less than 64 HRC. They could be built in non-tempered steel, but for profiles with very tight tolerances, consistent wear would be very fast. The speed with which comes the wear of a roller depends on the depth and the type of profile, but to get an idea of the number of rollers that can be consumed, you can refer to the description of the profile of a grinding wheel, from peripheral surface of a cylindrical grinding wheel. In this case, at least two profiling rollers are needed to obtain good tolerability profile. Naturally, the rollers, then can be carried forward again with the grinding operation.
During profiling, with peripheral speed of 1 m / sec, it is very important that no sliding between wheel and roller occurs, because then, the roller will wear away.
The best system is that the wheel is motorized, and the roll is pulled. This is because the wheel has a larger diameter, and therefore has a greater tensile strength, thus being easily pulled by the roller having a smaller mass.
It could also move the roller motorizándolo, but in that case a greater roller pressure against the grinding wheel would be required, resulting in a dangerous slide, particularly in the case of a new wheel.
Progress against grinding roller must have a value of 0.5 to 1 .mu.m / spin wheel. Our represented miniToolsCoating (Italy) specializes in building and sharpening HSS rollers profilers.
With the continuous improvement of steels and coatings, it has developed an optimal combination of these two elements, obtaining excellent results lasting rollers.
Building Crashing Rollers in S390, and ALTICROME coating, the tools have been shown that the length of the roller is up to twice that others with the same working conditions.
