What is Star Wheel
2021-04-29
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 and polishing pad. 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.
At present, the main material of the star wheel is FR4 Fiberglass Sheet, which combines various characteristics. The fiberglass board is currently the most suitable material for manufacturing star wheel on the market, such as: wear-resistant, easy to process and shape, simple processing procedures. However, fiberglass boards are electronic insulation materials, and the requirements for the wear resistance of the boards are not high. Therefore, the abrasion resistance of fiberglass is not enough compared to metal sheets. We have 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 FR4 Epoxy Fiberglass Sheet, but also increases the toughness and wear resistance of the board. It is more suitable for applications in the cruise ship industry.
There are two different types of star wheel
Metal star wheel
