The bench grinder, the essential machine for grinding, sharpening, deburring, trimming and shaping.
Deburring is the removal of metal burrs caused by cutting with a grinder. Deburring consists of removing a finer burr caused when cutting with a hacksaw, for example. Shaping is used to shape the metal and grind it.
The double grinder will therefore offer the possibility of mounting 2 grinding wheels with different grains for deburring and shaping, the mixed grinder will also have the advantage of offering a different rotation speed for each grinding wheel.
Grinding wheels are important, for roughing, choose a gray grinding wheel, for a finish a white grinding wheel. A leather disc will remove the wire after sharpening. These machines generally have a powerful, quiet and maintenance-free induction (asynchronous) motor that is perfectly protected from dust and moisture. Their frame is designed to offer maximum space between the electric motor and the grinding wheels, to sharpen all shapes of tools. The grinding wheels can be equipped with spark arresters and a protective casing for user safety. Sometimes LED lighting above each grinding wheel will improve the work. Anti-vibration rubber pads will guarantee maximum stability.
The grinder can also be two in one or multi-purpose, i.e. equipped with a grinding wheel on one side and an abrasive belt on the other, such as the famous Scheppach BGS700 grinder and belt sander! In the field of metalworking, more efficient types of grinders are offered, often equipped with a more powerful motor, the frame of these high-end grinders is made of high-quality cast iron to be suitable for polishing and brushing metal or plastic materials and non-ferrous metals. Remember to fix your grinder on your workbench and choose one with sufficient power depending on whether you are a DIY enthusiast or a professional!
