The first rule of thumb in precision grinding with vitrified bond wheels is to select the right wheel speed. Vitrified bonds can withstand high temperatures, but excessive speeds can lead to premature wear. …
Bernoulli's energy equation can be used to predict the pressure that creates the desired jet velocity. For example, a grinding wheel moving at 12,000 sfm (3,657 m/min.) requires a nozzle pressure close to 270 psi (18.6 bar) for the coolant jet to match the wheel speed. Lower wheel speeds require lower pressures.

Most bench grinding wheels are vitrified/glass bonded products and are very strong, but brittle. Do visually check all wheels for cracks or damage before use. In addition to the visual inspection, "Ring Test" all wheels before mounting on the bench grinder. Do check machine speed against established safe operating speed marked …
A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in …
The requirements generally apply to resin bonded grinding wheels for use on hand-held machines. EN 12413 specifies required values for the single-point side load and the working capacity depending on the type of grinding wheel. ... rotate freely without jamming on contact with the grinding wheel. The test chamber must be sufficiently large ...
In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine's speed is at or below the maximum …
The requirements generally apply to resin bonded grinding wheels for use on hand-held machines. EN 12413 specifies required values for the single-point side load and the working capacity depending on the type of grinding wheel. The side load capacity is verified by the single-point side load test and the impact test.

Higher wheel speeds, such as employed in high speed grinding, are predicated on the use of special grinding wheels and on machine design, including reinforced wheel guards, adapted to such operations. The infeed rates listed in Table 1-7.1 refer to the penetration of the grinding wheel into the work material.

Therefore, a fixed speed angle grinder, no matter the speed it is fixed at, will only be ideal for a few specific tasks. For instance, a 7,000 RPM angle grinder is fine for grinding and cutting hard metals, but won't work well on soft metals and for sanding wood, which requires a much lower speed, as low as 2,000 or 3,000 RPM.
