Industrial abrasives are usually made from hard minerals which can then be utilized for shaping or completing a piece of work by rubbing it. This actually causes part of the surface of the item to be worn away which results in a smooth and reflective surface. However, sometimes the surface may end up slightly more rough and this will result in a matte, satin or beaded finish to the work.

Today abrasives are used in a number of different industries and the actual physical and chemical composition of them will vary from one industry to the next. But although most abrasives will be used as a way of polishing the surface of a particular object they are also used to buff, grind, hone, drill, sharpen, sand or cut into them as well.

As mentioned previously most industrial abrasives today are made from hard minerals that have achieved a rating of seven or above on the Mohs scale. This scale is used as a way of testing and classifying just how hard a mineral is. Whilst there are other abrasives used for industrial purposes today which are made from synthetic stones.

The majority of synthetic stones used in abrasive materials have a similar chemical and physical composition to those of the minerals. However, the major difference between these two types of materials used in abrasive products is that minerals occur naturally.

The most common type of abrasive that is used for industrial purposes is the diamond. This particular abrasive not only occurs naturally but can also be synthetically produced. In nature the diamond will have been constructed from corundum but those which are manufactured are made from bauxite.

The diamond is one of the hardest substances known to man and yet there are plenty of minerals which are far softer than this and which can also are used for abrasive materials. One of the softest minerals being used today is calcium carbonate and this is frequently used as a polishing agent in toothpastes. It is this mineral in the toothpaste which will actually help to improve the whiteness of a person’s teeth overtime.

There are a number of different factors to be taken into consideration and these will affect just how effective the industrial abrasive is. The main one of these is the size of each grain that is used in abrasive methods. The actual size of each piece will vary from method to method. Some pieces are as little as 40micrometers whilst the largest pieces of abrasive grit (grain) will be no more than 2mm. In order to get the right size pieces of grit for use in industrial abrasives the minerals or synthetic stones will be crushed. The actual piece of the mineral or synthetic stone which comes into contact with the surface is very small this means much more pressure can be placed upon it.

When industrial abrasives are being used the force which is applied to each of the grains that make it up will cause part of the item on which they are rubbing to break away. But not only does the surface of the item begin to wear away so does the surface of the abrasive and this means that after a period of time the actual abrasive will need to be replaced.
