The star wheel is a fixture used in various plane polishing processes such as glass, lens, silicon wafer, hard disk, etc. It is also called polishing jig, polishing pad, etc. The polishing process has been developed for many years and has been very mature. In recent years, mobile phones, tablet computers and other popular electronic products have been widely popularized, touch screens have developed rapidly, and lens polishing has developed rapidly. Fiberboard.

The manufacturing process of the star wheel is very particular, and the polishing of lenses, silicon wafers, and gems are all very fine processes, so the requirements for the finished product of the cruise wheel are also very fine. Of course, there are still many glass factories that use stamping to manufacture planetary wheels. The reason is simply that the production cost of this method is very low, and there is no requirement for polishing workpieces. However, with the development of the industry and technological progress, more and more planetary wheels are now processed by computer gongs. The advantage of this method is that the processing accuracy of the finished product is very high, which can be controlled within 0.02mm, and the cut surface is very high. Smooth and clean, there will be no burrs, and even no traces of processing can be seen. At the same time, under the condition of mass production, the unit cost is also reduced, which will inevitably replace the stamping method in the future.

At present, the main material of the cruiser is FR-4 fiberglass board, which combines various characteristics. The fiberglass board is currently the most suitable material for manufacturing cruiser on the market, such as: wear-resistant, easy to process and shape, simple processing procedures, no Advantages such as damage to the polished workpiece. However, fiberglass boards are mostly electronic insulating materials, which do not require high wear resistance parameters. Therefore, compared with metal sheets, the abrasion resistance of fiberglass is not enough. JY Machinery has conducted professional explorations in this field and made targeted improvements to the production formula of epoxy resin board, which not only maintains the characteristics of FR-4 glass fiber board, but also increases the toughness and wear resistance of the board.
