Use of Industrial Abrasives

Jun 8, 2008
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.

There are a number of different industries which will use abrasives in their manufacturing processes and the chemical and physical makeup of them will vary from one to the next. As well as many industries using abrasives to polish items others use them for grinding, honing, buffing, sanding, cutting, drilling and sharpening.

As we mentioned before the majority of industrial abrasives being used today are made from hard minerals and has achieved a Mohs rating of seven or more. But as well as abrasives being made from minerals there are some which are made from synthetic stones as well.

The actual physical and chemical composition of these synthetic stones is very similar to those found in minerals. However, they cannot be classed as minerals as they have not been made naturally but rather produced through the use of chemical processes.

Of all the types of abrasives used for industrial purposes today diamond is the most commonly used. As well as being made naturally this particular abrasive material can also be produced synthetically as well. Most of the diamonds that will be dug from the ground have been made from corundum, whilst those that have been produced by man will have been made using bauxite.

Diamond is one of the hardest abrasives known to man, but there are plenty of much softer minerals which can be used as an abrasive. One such soft mineral is calcium carbonate and this is often used as a polishing agent in toothpaste. It is this mineral in your toothpaste which helps to improve the whiteness of your teeth.

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.
