Is there any routine maintenance I should perform on my diamond disk?

Keeping your disk around and in working order for a very long time takes a few routine chores to keep it going.

First off is cleanliness.

The worst enemy of your diamond disk is glass. "How's that?" you say.

Well, when you grind your pieces with your disk, ground glass particles can build up on the disk's surface. If allowed to dry onto the disk, these large buildups can prevent your disk from grinding. This buildup shows white areas, usually around the edge of the disk. If left on its own, these deposits will eventually build up higher than the diamond, causing your glass to ride on top of the ground glass instead of the diamonds.

The easiest way to prevent this is to put a jug of water next to your grinder. After you have finished grinding, or even between every couple of pieces, pour some water over the moving disk and rub it with a plastic bristled brush to wash away any ground glass that may have accumulated on the surface.

Once you get into this habit, you'll never have to worry about the buildup of ground glass again, and your diamond disk will last much longer.

Keeping the magnet back clean is also a good idea. If you allow a buildup of rust or debris on the back of the magnet, it can compromise the connection to the grinder or even create a high spot on the top of the disk that can cause deep gouges in your glass or wear the plating off the disk surface.
