The grinding wheel and the work both are guided in precise paths. The precision grinding in accordance with the type of surface to be ground is classified in many forms of precision grinding, but the four major industrial grinding processes are: a. External Cylindrical Grinding: It produces a straight cylindrical or tapered surface on a
Cylindrical grinding Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required.
Cylindrical grinding is usually a secondary operation after turning. Often the same center holes used for between-centers turning may be used for grinding the part. As friction is more of a factor in grinding than in other processes, fixture design must allow for coolant flow and swarf removal. If not built into the grinding machine itself, the ...
5. Move the grinding wheel down using the vertical table handwheel until it barely makes contact with the dresser. 6. Turn the machine off after making contact with the dresser. 7. Turn the machine on again. While the wheel is spinning, lower the grinding wheel down in the Z direction until it makes a small plume of dust. 8.
an ellipse, a cam, or a crankshaft. This type of grinding operation is performed only for cylindrical jobs. The cylindrical grinding operation is two types: 1.External cylinder grinding. 2.Internal cylinder grinding. f SURFACE GRINDING. Surface grinding uses a rotating abrasive wheel to remove. material, creating a flat surface.
