Proper mounting procedures for grinding wheels
اقرأ أكثر• Check the grinding wheel before mounting it. Make sure it is properly maintained and in good working order. • Follow the manufacturer's instructions for mounting grinding wheels. • Keep face of the wheel evenly dressed. • Ensure that the wheel guard covers at least one half of the grinding wheel.
اقرأ أكثرThe proper mounting of a grinding wheel is very important. An improperly mounted wheel may become potentially dangerous at high speeds. The specified wheel size for the particular grinding machine to be used should not be exceeded either in wheel diameter or in wheel width. Figure 5-12 illustrates a correctly mounted grinding wheel.
اقرأ أكثرDON'T use excessive pressure when mounting a wheel. Tighten enough only to hold wheel firmly. DON'T alter a wheel hole or force it on a spindle. DON'T mount more than one wheel on an arbor. DON'T use any Type 1/41 or 27/42 cutting wheel for grinding. DO not apply any side pressure on a cutting wheel.

اقرأ أكثر2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

Flanges When mounting most grinding wheels, use flanges of equal diameter and bearing surface. For exceptions, see ANSI B7.1. Safety Gloves Grinding applications are conducted in harsh environments. The use of proper fitting gloves is recommended.

اقرأ أكثرGrinding wheels shall fit freely on the spindle and remain free under all grinding conditions. A controlled clearance between the wheel hole and the machine spindle (or wheel sleeves or adaptors) is essential to avoid excessive pressure from mounting and spindle expansion.
اقرأ أكثرThe proper use of blotters can aid in preventing wheel breakages. Blotters, by definition, are compressible ... In other words, wheel blotters should NEVER be smaller than the machine's mounting flanges. The grinding wheel is driven by the machine flanges. The forces that drive the wheel are transmitted through the bearing surface of the flanges.
