A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Advantage of grinding process. There are following advantage of grinding process as mentioned here. Investment is less. Working principle and operation is simple. It does not require additional skills. Surface finishing will be approximate 10 times better as compared to milling and turning process of machining.
Special types of grinders are grinding machines made for specific types of work and operations, for example Tool and cutter grinders. These grinding machines are designed to sharpen milling cutters, reamers, taps and other machine tool cutters. The general purpose cutter grinder is the most popular and versatile tool grinding machine.

GRINDING. MACHINE GRINDING • Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. • When the moving abrasive particles contact the work piece, they act as tiny cutting tools, each particle cutting a tiny chip from the work piece. • The grinding machine supports and rotates the grinding abrasive wheel and often supports and.
MILLING MACHINE OPERATIONS The milling machine removes metal with a revolving cutting tool called a milling cutter. With various attachments, milling machines can be used for boring, slotting, circular milling dividing, and drilling. This machine can also be used for cutting keyways, racks and gears and for fluting taps and reamers f Types .

Two general types of machines have been developed for this purpose those of the planer type with a reciprocating table and those having a rotating worktable. Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle. The.
Advantages of grinding. Grinding is a universally known process. Most workpieces can be ground, independent of their shape. Hard turning, on the other hand, has geometric limitations, as is the case with long and thin components. Wide surfaces can be finished effectively, often with a single plunge grind operation.
W. Brian Rowe, in Principles of Modern Grinding Technology (Second Edition), 2014. Flexible Grinding Operations and Peel Grinding. Flexible grinding operation suggests that a family of components or possibly several families can be produced flexibly on one automatically controlled machine tool. For example, it is possible that cylindrical components having several diameters and shoulders could.
Faulty grinding operation Do not allow wheel to separate from work edge. Reduce wheel infeed rate. Reduce wheel speed and wheel diameter. Wheel specification unsuitable Use softer grade wheel. Out of cylindricity Wheel specification unsuitable For plunge grinding, ensure that wheel width is larger than work width. Use harder grade wheel.
