2. Abrasive machining - Wikipedia

   en.wikipedia.org/wiki/Abrasive_machining

   The most important property of an abrasive is its hardness. For abrasive grains to effectively cut, they must be significantly harder than the workpiece material. They can be grouped based on their hardness into two categories: conventional abrasives and superabrasives. Conventional abrasive materials have been used since the advent of machining.

3. Oscillating multi-tool - Wikipedia

   en.wikipedia.org/wiki/Oscillating_multi-tool

   A non-symmetric scraper blade for an oscillating power tool Saw blade for an oscillating power tool. Various attachments and blades are on the market, giving these machines a wide variety of uses. The blades can be separated into 5 main categories: cutting; tile, grout and masonry; sanding; scraping; and polishing.

4. Grinding (abrasive cutting) - Wikipedia

   en.wikipedia.org/wiki/Grinding_(abrasive_cutting)

   Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

5. Belt grinding - Wikipedia

   en.wikipedia.org/wiki/Belt_grinding

   Belt grinding is an abrasive machining process used on metals and other materials. It is typically used as a finishing process in industry. A belt, coated in abrasive material, is run over the surface to be processed in order to remove material or produce the desired finish.

6. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...

7. Belt sander - Wikipedia

   en.wikipedia.org/wiki/Belt_sander

   A belt sander or strip sander is a sander used in shaping and finishing wood and other materials. [1] It consists of an electric motor that turns a pair of drums on which a continuous loop of sandpaper is mounted. Belt sanders may be handheld and moved over the material, or stationary (fixed), where the material is moved to the sanding belt.
