Re: Newbie question about a Si Carbide Wheel X 2

Hi Dirk,

For safety's sake I would replace the wheels. There is a possibility of serious injury if those wheels disintegrate while in use, and that can happen due to stresses caused by being out of balance.

That said, if the wheels are unbalanced due to one side absorbing water while immersed, that condition should be betrayed by vibration while the machine is running at speed. However, if you aren't already experienced with these machines, you may (mistakenly) assume that such tell-tale vibration is normal. Assuming nothing is bent, the bearings are good, the arbor and wheels are in balance, the motor is securely mounted, and the belt drive is properly set up, it should actually run very smooth.

If you are going to cut only softer stones such as turquoise on the machine, then silicone carbide wheels may get the job done for you. But particularly if you are going to cab harder materials such as agate and jasper, or very tough materials such as jade, what you really want is a set of diamond wheels. These are more expensive than silicon carbide of course, but once you have cabbed on diamond wheels, there is no substitute...

Regardless of the wheels you are running, always wear ANSI approved polycarbonate eye protection while you are working on the machine. I once witnessed a cab that had separated from its dop propelled off a wheel, bounce off a table, and still travel across the room with sufficient velocity to crack a window on the other side of the room upon impact. I've been religious about wearing safety glasses while cabbing ever since.
