Double disc grinders, also called tabletop or bench grinders, perform grinding and polishing operations. They are usually mounted to a workbench or other surface. It is a type of grinder in which two disk-shaped grinding wheels attached to both ends of a motor shaft fixed horizontally rotate. The grindstones on both ends are often mounted with different grit sizes, so rough grinding is performed with a rough grindstone mounted on one end, and finishing work is performed with a fine gritstone mounted on the other. This allows efficient work without having to change the grindstones each time.
Double-headed grinders are used for processing materials and rough grinding and polishing blades. Material processing is used to form small materials that cannot be fixed in a vise and remove burrs after cutting and processing metal materials.
In rough grinding of blades, it is used to grind carpentry tools such as chisels, knives, and saw blades. It is also used to grind small lathe bits that are difficult to fix in place.
A buff made of cloth or linen can be attached in place of the grinding wheel for fine-finishing grinding work. A dedicated blade grinder is an option for heavy blade grinding, while a buff grinder is an option for heavy finishing work with a buff attached.
Double disc grinders are used on workbenches and are relatively more limited in their applications than other grinders. Still, their stability makes them suitable for grinding by pressing against the material.
The base of the grinder is located at the bottom, and for models with larger output and size, holes are drilled in the base to fix the grinder to a workbench or other surface with bolts. The main body has a switch to turn the machine on and off, and some models have a dial to adjust the rotation speed. Some models are designed to mount grinding wheels on both ends, and some are equipped with a work rest to stabilize the object to be ground or polished, a safety cover, a magnifying glass, and a large dust collector.
The grit size of the grinding wheel that can be mounted is generally 36 to 120 when used mainly for metalworking. The model specifies the diameter range of grinding wheels that can be used. Models for relatively small grinding wheels of 205 mm or less operate on single-phase 100 V, while models for large grinding wheels over 205 mm operate on three-phase 200 V.
