WET GRINDING. The raw materials are taken in a ball mill and them grinded with water for certain hours. The grinding media is usually alumina because it has good wear resistance and good density. This process is known as wet grinding. The raw material will be obtained in a slurry form at the end of the wet grinding process.
Show all Honing, Lapping, and Superfinishing Machines Manufacturers Honing, lapping and superfinishing equipment improve surface finish or geometry to tight tolerances. Honing, lapping and superfinishing are performed under low speed and pressure conditions, resulting in a gentle action as compared to grinding and machining processes.
The process of producing feed pellets can roughly be described as a plastic molding operation of the extrusion type. Feed ingredients are made up of various compounds such as proteins, acids, sugars, fibers, and minerals. These products can be softened (conditioned) by the addition of heat and water.
Nonetheless, the most common applications involve grinding and cutting with resinbonded wheels. The old adage "accidents can happen" applies to grinding and cutting just as it does to most aspects of our daily activities, whether it be walking down a flight of stairs or driving our cars.

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damagefree. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.

The Surface Grinder is mainly used in the finishing process. It is a very precise tool which uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface which is held in place by a vise. This vise, which is part of a table, or carriage is moved back and forth under the abrasive wheel.
More than 70% of semiconductor manufacturers'' investment is poured into frontend, or wafer processing, which is essential in semiconductor production. Tokyo Seimitsu has timeproven experiences in the process by supporting with highend test and backend equipment, and by providing frontend equipment such as CMPs that planarize the wafer surface.
• Use caution when grinding in corners because a sudden, sharp movement of the grinder may occur when the wheel strikes the secondary surface. • Maintain an angle of approximately 15° to 30° between the disc and the working surface . • Do not apply side pressure on the grinding or cutting wheel.
