Everything is constantly evolving, even human beings are no exception, not to mention the other equipment or instruments, tools, resin grinding wheel is an important tool in the manufacture of grinding tools, of course, is a step-by-step development, today to say is the resin grinding wheel automatic molding technology is how to develop!
Early in the early 80 's, people in the industry to explore this aspect of technology and try. At that time was imported from abroad an automatic molding press. This machine is designed to be quite compact, and it differs from ordinary presses in that it is a feed system.
Its working principle is: the mixture into the top of the hopper, through the vibration, fall on the conveyor belt, with scraper scraping flat, and then adjust the transmission speed, the final material will be sent to the weighing bucket, weighing accurately after the material into the mold cavity.
The design principle seems to be quite effective in improving productivity. But there is a real problem is that no matter how to adjust, always can not reach the ideal level of design. Because the sheet grinding wheel is not like smelting corundum, silicon carbide, raw material error can not be too large, through the conveyor belt feeding, to be accurate weighing is not an easy thing to adjust repeatedly, not only improve efficiency, but waste a lot of time. Now using a compromise approach, around the tricky feed system, artificial feed, with multi-position presses, labor intensity reduction, production efficiency can also be guaranteed.
The ideal feed system still needs to be improved and opened up, once mastered, this technology will be able to make the production of thin grinding wheel like the production of coated abrasives, efficient, fast, fully mechanized, automated, to the thin market to bring earth-shaking changes.
