It has been widely used in various heavy-duty combined processing machine tools, CNC machine tools, high-precision EDM cutting machines, grinders, industrial robots and even general industrial machinery. The manufacturing of rolling linear guides is still in the initial stage, mainly manifested in: few varieties, small output, easy wear of balls, low service life, high noise, traditional sliding guides are not easy to assemble and the guide surface must be scraped, which is both troublesome and time-consuming. Once the machine tool has poor accuracy, it must be scraped again.
