The final step in jewelry manufacturing is polishing a newly created piece to a mirror-like finish. This is easily done with a motor powered polishing machine. The machine has a motor that turns a polishing wheel, called a wheel buff.

Some polishing machines have two arms since two wheel buffs are needed – one wheel is stiffer and used first and the second wheel is softer and used second. Wheels are usually five to six inches in diameter and are usually made of muslin.

Always hold the jewelry away from you, in breakaway grip, and under the wheel rather than on top for better control and for safety reasons. The wheel spins towards you, so holding the jewelry under the wheel results in it being shot backward in the event that the wheel grabs the piece from your hands.

Using a polishing machine is a dusty and dirty job, so ventilation is important. Many polishing machines come with blowers to capture dust. Rio Grande has a great selection of the very popular Dura-BULL polishing machines on their website.

You could build your own polishing machine too. You need a motor that runs at 1,725 rpm. You will need tapered spindles to attach to the motor in order to mount the buffing wheels. Know the diameter of the motor before purchasing the spindles. The motor then needs to be mounted securely to a work bench or table.
