Grinding
- An abrasive machining process that uses
grinding wheel as the cutting tool
-Hand-cranked knife-sharpening stones (grindstone)
-Handheld power tools (angle grinder)
-expensive industrial tools
-Small bench grinders often found in
garages and basements
Surface grinding
- Is used to produce smooth finish on flat surfaces
- Most common grinding operation
- Widely used
- Typical workpiece materials include cast iron and mild steel
-Grinding at high temperatures could weaken the material and it is more inclined to corrode.
Cylindrical grinding
- Also called center-type grinding
- Removes cylindrical surfaces of the workpiece
- Workpiece must be constantly rotating
-
Creep-feed grinding
- Invented in Germany late 1950s
- It is used removing large amounts of material
- Is highly accurate
- Used for high rates of material removal
- Is used to keep workpiece temperature low
Others
Form grinding is a specialized type of cylindrical grinding where the grinding wheel has the exact shape of the final product.
Internal grinding is used to grind the internal diameter of the workpiece.
