Check out our Magnetic Disk Organizers... the perfect place to store your discs!  

During a recent workshop, we had the opportunity to use the 12" machine to create, bevel, and polish small dichroic jewelry pieces... it was awesome. I just had to add it to the studio. ....and then we added an 18" too! You can never have too much of a good thing!!

Using these magnetic flat diamond discs is absolutely the cleanest, fastest way to grind and polish your work. This machine will be hard plumbed.

The 18" beveler and grinder is a large and versatile unit designed to cold-work pieces of glass. With the appropriate accessories, this unit will grind, shape, and polish small workpieces. There are several features built into this variable-speed lapping unit, including a water sleeve that allows water to come up through the shaft center and disperse from the middle of the plate if you choose, and an overhead loc-line® water supply. It also has a 5/8"-11RH female thread that accepts a variety of different diamond finishing tools. An optional male-to-male brass fitting for female treads is also available.

The speed control allows speed ranges from 200rpm to 1100rpm. The bearings have been set 11" apart on the shaft to give rigidity and stability to the 18" blanched and precision ground plate. A wash-down motor and controller are perfect for wet environments. This flat lap machine is made with 11-gauge box tubing and 16-gauge removable side panels topped with heavy-duty powder coating. It comes with a full 1-year warranty on parts.

      Glass shop work horse

      As one of our glass shop work horses, this grinder/polisher works great to get a professional finish on our glass bowls and vases. It’s great for squaring up & finishing wall pieces, too.

      Excellent product!

      This is a great investment for anyone who is serious about the quality of their finished glass art. It gives you the ability to create professional edges on everything from thick pieces, drop vases, jewelry, strip-cuts, and countless other types of mid-sized fused glass creations.
