These robot workstations are automatic production lines developed by ZZSM for the production of cylindrical grinding wheels and / or end surface grinding wheels made from superhard abrasive materials. They come in with two types lines, i.e., light load lines and heavy load lines. The light load line consists of a prepressing machine, a manipulator truss, a set of 200T press main(s), a light load robot, a mold unloading machine, a screw removal machine and a cleaning machine. The heavy load line consists of a prepress, a set of 315T press main(s), a heavy load robot, a mold unloading press, a screw removal machine and a cleaning line. These robot workstations realize, at the same time, various types of automatic operations of prepressing, handling, pressing, mold unloading, screw removal, cleaning and so on for the productions of grinding wheels. It greatly reduces the labor intensity, ensures the production quality, improves labor efficiency.
