One of the bottlenecks affecting the production cost and efficiency of the resin grinding wheel is its forming technology. Resin grinding wheel requires large-scale production, and it is ideal to automatically press-form, saving labor costs and improving efficiency.
As early as the 1980s, the industry has carried out explorations and attempts in this area and introduced an automatic forming press from abroad. The device is compact in design and differs from conventional presses in that it has only one additional feed system.
Its working principle is: put the mixture into the upper hopper, shake it, drop it on the conveyor belt, scrape it with the scraper, adjust the conveying speed, send the material to the weighing hopper, weigh it accurately and then feed it into the dies. Cavity.
From the design principle, it should be fast and effective, but there is a fatal flaw here so that no matter how it is adjusted, it will never reach the ideal level of design. Because the fast working grinding wheel is not like smelting corundum and silicon carbide, the error of raw materials cannot be too large. It is not an easy task to weigh accurately through conveyor belt feeding. Repeated adjustment can not only improve efficiency but also waste a lot of time.
Nowadays, a compromise is adapted to bypass the more difficult feed system, artificial feed, multi-station press, labor intensity reduction, and production efficiency.
In the future, we still need to broaden our horizons and create new ways to design an ideal feed system. Once successful, the production of grinding wheels will be as efficient and fast as the production of coated abrasives, fully mechanized, automated, and completely bid farewell to labor-intensive production, grinding wheels the market will also undergo tremendous changes!
