Comparing this ELID grinding operation to conventional grinding leads to these conclusions: • ELID double-sided grinding (duplex grinding) can be employed to produce mirror-like surface finishes. • Surface finish of workpieces ground with ELID was better than the roughness of the workpieces ground conventionally. •
Traditionally-speaking, grinding processes are reserved for small rates of metal removal and fine finishing operations. However, creep-feed grinding can also be used for large-scale metal-removal operations more in line with traditional machining techniques such as milling or broaching.
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.
This type of grinding operation, two grinding wheels are fitted parallel with a 5-10-degree angle which is provided to obtain a longitudinal motion of the workpiece. A cylinder rod is placed between the two-grinding wheel due to the tilted angle. This allows the workpiece to automatically pass through the wheels and the smooth surface is obtained.
