A. Pizzi, C.C. Ibeh, in Handbook of Thermoset Plastics (Third Edition), 2014 Bonded and Coated Abrasives. Grinding wheel and emery paper are the major outlets for phenolic resins in bonded and coated abrasives. Leo Baekeland introduced the first phenolic resin-bonded grinding wheel in 1909. Today, phenolic resin-bonded grinding wheels are the most popular type of grinding wheel.

Product life is an additional factor in the choice of grinding wheel diameter. Larger-diameter wheels last longer. Especially in applications where the operator must run the grinding wheel for a sustained period, using a larger-diameter wheel can improve productivity by reducing the number of times the operator must stop and replace the abrasive.

Helically grooved grinding wheels have been shown to improve the performance of flat grinding processes by reducing the forces and spindle power during grinding. However, to date, helical grooves have never been applied to a profile grinding process. In this paper, we demonstrate experimentally that helical grooves are highly beneficial to profile, creep feed …

In general terms, the abrasive grit size range for grinding wheels runs between 12 grit for rough grinding operations, such as those found in steel mills, and 220 grit for very fine/precision grinding operations. 32A46- I 8VBE – The third part of the marking system identifies the grade or hardness of the wheel.
