2. Disc cutter - Wikipedia

   en.wikipedia.org/wiki/Disc_cutter

   A cutoff saw is used for cutting larger items, like heavy metal stock, metal studs, and for cutting large metal pipe. The cutting discs for this tool are usually 10 or 12 inches in diameter, with a composition like that of the smaller wheels mentioned above. When cutting heavy materials the cutting discs may require lubrication or coolant to ...

3. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

4. Blade grinder - Wikipedia

   en.wikipedia.org/wiki/Blade_grinder

   However, meat grinders (and food mills) use a scissor cutting action as the blades rotate against a perforated metal plate. Meat grinder blades rotate at a much slower speed than blade grinders, which may rotate at speeds as high as 20,000 to 30,000 rpm; for example, the Steele model mixer-grinder by Indian appliance manufacturer Preethi has a ...

5. Milling cutter - Wikipedia

   en.wikipedia.org/wiki/Milling_cutter

   Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).

6. Angle grinder - Wikipedia

   en.wikipedia.org/wiki/Angle_grinder

   Angle grinder. An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing.Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.

7. Grinding (abrasive cutting) - Wikipedia

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

   The tolerances that are normally achieved with surface grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [ 4 ] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck , either electromagnetic or vacuum, and a reciprocating table.
