Denver Glass Machinery has developed a diamond grinding system that eliminates the need for several separate grinding wheels. Our interchangeable magnetic discs allow the operator to go from rough grind to a final polish with one machine. Obtain true flat surfaces, seam edges and bevel large pieces of glass. Results can be fully controlled by selecting the correct abrasive and the right amount of water with the desired rpm's to achieve the finish that is needed.

Model: DG-18, Flat Lap Grinder

The DG-18 Flat Lap Grinder features a 1/2 horsepower, constant torque SCR controlled, variable speed motor. The 18" (30.5cm) lap plate is precision balanced to run smoothly at high rpm's. Adjustable water spray nozzle for complete control. The splash tray is made of stainless steel with a removable rubber splashguard. Comes with a magnet pad so you can use either magnet backed or metal backed grinding discs. Choose either our metal backed electrplated diamond discs or the 3M brand magnet backed bonded (sintered) diamond discs.

Discs are metal backed to hold tight to the magnet pad provided with your flat lap grinder. Available in 12" (30.5cm) and 18" (46cm) diameters for use on our DG-12 and DG-18 diamond lap grinding machines. Available in mesh sizes to go from rough grind to pre-polish with any type of work. For example, the 60 mesh disc is very aggressive and is designed to remove large quantities of material. Good for casted sculptural work where large amounts of glass need to be removed. For most applications you would start with the 120 mesh disc and go to 200 mesh, then the 400 mesh and 800 mesh. followed by the felt pad with cerium oxide for the final polish. Call our expert sales team for advice on which pads to use for your particular application.
