Nov 21, 2018 · 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 grinding process.
Grinding Wheel Materials provides a detailed overview of the various abrasive and bond materials used in grinding wheels. The properties of the abrasive grains and bond material are important factors in any grinding operation. Abrasives vary not only in type but also in size, hardness, and friability. Bond material can vary in porosity, strength, and amount.

(1) The strength of a grinding wheel (vitrified) is lower than that of glass or porcelain. Therefore care must be taken to prevent damage to grinding wheels during shipping, transport, and other handling. Because grinding wheels appear to be extremely strong, there is .
May 29, 2018 · The heat carrying capacity of the wheel is required to be higher for the higher temperatures generated due to grinding carried out at high speeds. If the porosity is kept higher for this purpose, when the grinding wheel rotates at a high speed, there is a possibility that the strength of the grinding wheel may be less.
Dec 01, 2006 · CBN grains do not chemically react with steels and retain their strength above with CBN wheels also improves the fatigue strength and extends the useful life of the cutting tool. However, before replacing an aluminum oxide wheel with a CBN grinding wheel it is important to make sure that the grinding system can take advantage of ...
Dec 15, 2000 · The strength of a bond is designated in the grade of the grinding wheel. The bond is said to have a hard grade if the spans between each abrasive grain are very strong and retain the grains well against the grinding forces tending to pry them loose.
We are emerging as a leading company engaged in manufacturing and supplying highgrade Grinding Wheel Strength Test Machine that is made from excellent grade components with cutting edge techniques. Offered machine is mainly designed for testing strength of grinding wheels which are used for polishing of items.
Grinding wheels are made from pressed and bonded composite material, forming a solid and circular shaped component for tools and machines. ... The highstrength grinding performance and capability to sustain the microedge power of the diamond abrasive grains for a long period reduce the number of grinding cycles, saving energy.

May 10, 2020 · Small wheels of 25mm diameter cost up to 10 for conventional abrasive and for diamond up to 200.; Large wheel of 500mm diameter and 250mm width, the cost is about 8000 to 20000.; Life of Grinding Wheel. When a grinding wheel is applied to the workpiece, the sharp edges of the abrasive grains which are cutting, will, in the end, lose their cutting effect and become dull.
Identify the grade of the grinding wheel. You can find out the strength of a bond in the grade of the grinding wheel. You can tell if a bond is hard if the spans between each abrasive grains are resilient and hold the grains well against the grinding forces that try to loosen them. You can also tell a softgrade bond if minimal force is all it ...
For example, nearly pure white wheels are the toughest, hard wearing and used for grinding heatsensitive and highstrength steels. Siliconcarbide based abrasives are used for cutting gray and chilled iron, cement, stone, and other nonferrous materials (copper, brass, soft bronze, aluminum, magnesium) and nonmetallic (ceramics, gemstones ...
