Description:

The Heavy-Duty Grinder and Polisher is a benchtop lapidary finishing machine built for shaping, smoothing, and polishing hard materials using water-fed grinding and polishing wheels. It is constructed as a heavy steel unit with a fixed motor-driven arbor designed to carry multiple grinding and polishing stations. This style of machine is used when you need controlled, repeatable material removal for tasks like truing edges, flattening faces, refining contours, and bringing a surface up through pre-polish and final polish. In a glass studio, it is commonly used for coldworking operations such as smoothing sharp edges on thick glass, shaping fused or cast glass components, and refining the fit and finish of parts before assembly. The weight and rigid frame help reduce vibration, which improves control and surface quality during grinding and polishing.

How it is used:

Set the unit on a stable bench where water splash and slurry can be managed safely. Install the appropriate grinding or polishing wheels for the stage of work you are doing. Turn on the water feed so the wheels stay wet and cutting debris is carried away. Present the glass or stone to the wheel with steady pressure and keep the work moving to avoid flat spots and overheating. Progress from coarser grinding to finer finishing steps, then switch to polishing wheels for final surface refinement
