Covington Machines - Variable Speed Grinder/Polisher - 110v
SKU:
COV592VSP
Description:
A variable speed grinder and polisher is a bench-mounted coldworking machine built around a heavy-duty electric motor, a variable speed control, and a rotating arbor designed to carry grinding and polishing wheels. In glasswork, this style of machine is used after lampworking, fusing, or hot shop work when you need to true up a surface, flatten a base, refine a profile, remove sharp edges, or bring a piece through sanding into a polish. Variable speed is especially useful for glass because it lets you slow the wheel down for better control, reduced chipping on delicate edges, and cooler running when you are working finer grits or polishing pads. This is a 110v unit intended for standard shop power and is commonly paired with diamond wheels and polishing accessories for wet grinding and finishing.
How it is used:
- Secure the grinder polisher to a stable bench where you can work comfortably with water management
- Install the appropriate grinding wheel, sanding drum, or polishing pad for the stage of finishing you are doing
- Set up water feed or coolant and splash control to keep the wheel wet and control glass dust
- Start at a lower speed for delicate work or finer grits, then increase speed as needed for stock removal
- Support the glass firmly and present it to the wheel with steady, even pressure to avoid grabbing and edge chipping
- Progress through finer grits and polishing steps until the surface finish matches your goal
- Rinse the work area and wheels thoroughly after use to prevent abrasive contamination between steps
