1 "ABEC" is applied for ball bearings and "RBEC" for roller bearings. Notes 1: JIS B 1514, ISO 492 and 199, and DIN 620 have the same specification level. 2: The tolerance and allowance of JIS B 1514 are a little different from those of ABMA standards.
Thus, the grinding pressure of a grinding roller can be measured at any time without stopping the coal grinder, and the loading capacity can be controlled at any time. A maintainer does not need to reenter the cavity of the coal grinder for measuring the deform capacity of the spring. Thus, the safety is ensured.
The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.
