The superior range of grinding papers are designed to offer high quality grinding in preparation to metallurgical polishing using a water cooled grinding machine. 

When choosing the right form of grinding paper to prepare your samples your next project, your decision will largely come down to which quality of finish you desire, while also taking into consideration the surface material you are working on. Aluminum Oxide and Silicon Carbide are the two most widely used forms

Brown aluminum oxide provides longer life because the grains crack and break down at a slower rate. This will increases life, but you have to sacrifice some appeal on the finish, which is acceptable in the courses grinding steps.   

Abrasives Will Wear

Abrasives tend to “clog up” with use. In addition, the individual grains will wear down and grow dull. Unless steps are taken to expose fresh material, they soon become ineffective. On grinding machines, this is usually accomplished by dressing the wheel, but for virtually all other abrasives this is not an option.

Abrasive manufacturers have made great efforts to make their products “friable” or semi-friable, which means the abrasive breaks away when dull, bringing fresh material to bear. By adding ceramic to aluminum oxide, for example, a hybrid is created that is both hard and strong yet friable, making it suitable for steels and alloys that would otherwise be difficult to grind.

Working with Abrasives

Abrasive selection is a complex decision and should not be taken lightly. Here are some key considerations when choosing one.

1. Always use the finest grit grade that will get the job done. If the grit is too coarse, it will create rougher-than-desirable surface finishes; if the grit is too fine, it will increase cycle time and cut into job profitability.
2. Watch out for “bargain” abrasives. They are rarely a bargain and will only lead to poor sample quality and re-preparing of samples..
3. Be consistent in the application of any abrasive. Develop a process plan that balances throughput and part quality—then stick to it.
4. If you are using abrasive pads or paper, use an appropriate block or holder for more consistent results.
5. Set aside time for testing any new abrasive to determine how long it should last and how much material it can remove in a given period. Document these values as part of your work instructions. Don’t be afraid to try something new.
6. Pushing an abrasive too long leads to unpredictable part quality. But not pushing one long enough can lead to higher expenses when abrasives are disposed of prematurely.

So the next time you need to shine up some parts, don’t just grab whatever 80-grit paper the tool crib has handy. Instead, consult with your supplier to discuss what’s best for your application.
