2. Grinding wheel - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel

   Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Trueing the wheel makes the grinding surface parallel to the ...

3. Spark testing - Wikipedia

   en.wikipedia.org/wiki/Spark_testing

   Spark testing of tool steel Spark testing of mild steel. Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. [1]

4. Grinding wheel wear - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel_wear

   Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes.

5. Bench grinder - Wikipedia

   en.wikipedia.org/wiki/Bench_grinder

   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. A wire brush wheel or buffing wheels can be interchanged with the grinding wheels in order to clean or polish ...

6. Grinding (abrasive cutting) - Wikipedia

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

   A man grinding on metal using an angle grinder, causing a lot of sparks. Grinding is a type of abrasive machining process which uses a grinding wheel as cutting tool. A wide variety of machines are used for grinding, best classified as portable or stationary: Portable power tools such as angle grinders, die grinders and cut-off saws

7. Diamond grinding cup wheel - Wikipedia

   en.wikipedia.org/wiki/Diamond_grinding_cup_wheel

   There are two common methods to manufacture diamond grinding cup wheels: hot pressing and cold pressing. The hot pressing method is to directly sinter the diamond segments in molds under a certain pressure in the dedicated sintering press machine, and then fix or connect the diamond segments onto the grinding wheel’s body via high-frequency welding, laser welding or mechanical mosaic method.
