Parallel grinding wheel
Crystal grinding and finishing is an important process in the processing of semiconductor materials. Parallel grinding wheels are mainly used in the process of crystal excircle or plane finishing, realize the characteristics including the stable processing size, material layer free from sharpening, stable processing quality, long service life, etc. This product has been stably used in Japanese, German and domestic grinding machines, and has unique advantages in rough grinding and fine grinding.
Excircle grinding (round bar excircle), plane grinding (square brick surface, crystal bar ending, positioning edge) Suitable materials: hard and brittle materials, such as industrial artificial sapphire, monocrystalline silicon, quartz glass, etc. Product appearance: parallel, bowl type Product specifications: Diameter 100-400mm Inner hole 32-203mm Sand width 10-40mm Sand height 5-10mm Product processing parameters: feed volume 0.02-0.3mm Design and develop adaptive products according to the actual working conditions of customers;
1. Free of trimming
Our products use the ceramic binder, and do not need to dress the grinding wheel in processing. Compared with the current products which commonly use the resin binder, our products may eliminate the sharpening process, and reduce the processing time by about 20%.
2. Long life
The life of the ceramic grinding wheel is about 3 times that of the resin grinding wheel, which can save about 20% of the cost.
