2. Grinding wheel - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel

   Spacing or structure, from 1 (density) to 17 (least dense). Density is the ratio of bond and abrasive to air space. A less-dense wheel will cut freely, and has a large effect on surface finish. It is also able to take a deeper or wider cut with less coolant, as the chips clearance on the wheel is greater.

3. Grinding (abrasive cutting) - Wikipedia

   These types of grinders are commonly used to hand grind various cutting tools and perform other rough grinding. [1] Depending on the bond and grade of the grinding wheel, it may be used for sharpening cutting tools such as tool bits, drill bits, chisels, and gouges. Alternatively, it may be used to roughly shape metal prior to welding or fitting.

5. Grinding dresser - Wikipedia

   en.wikipedia.org/wiki/Grinding_dresser

   A grinding dresser or wheel dresser is a tool to dress (slightly trim) the surface of a grinding wheel.Grinding dressers are used to return a wheel to its original round shape (to true it up), to expose fresh grains for renewed cutting action (including cleaning away clogged areas), or to make a different profile (cross-sectional shape) on the wheel's edge.

6. Grinding machine - Wikipedia

   en.wikipedia.org/wiki/Grinding_machine

   A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding. It is a type of material removal using an abrasive wheel as the cutting tool. [1] Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

7. Cutting tool (machining) - Wikipedia

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

   Linear cutting tools include tool bits (single-point cutting tools) and broaches. Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these ...
