1.the expansion of the ordinary protective cover is to rely on the friction between the nodes and the nodes to promote each other, because the friction between the nodes is not the same, resulting in the expansion of the node movement is not synchronous, not parallel, some nodes even have the phenomenon of stagnation. the impact vibration, noise, shorten the service life and affect the overall performance of the machine tool, in the machine tool moving at high speed, its shortcomings are particularly prominent. high-speed synchronous telescopic guide rail protective cover is equipped with synchronous mechanism, so that each piece moves synchronously when it is telescopic, avoiding impact vibration, reducing noise, extending service life, truly achieving stable operation, freely telescopic, so that the overall performance of the machine is guaranteed.
2.the special structure of the oil scraper and high elasticity, high wear resistance, high temperature resistance, oil resistance of the special oil scraper make the sealing, protection performance is more reliable, longer service life; the special structure of the oil scraper and the oil scraper makes it very convenient to clean and replace the oil scraper, the maintenance is more simple and convenient, and the overall reliability is higher.
3. the protective cover has a wider range of applications. in addition to the machine tools with high moving speed, high acceleration and deceleration, it is also especially suitable for the machine tools with large stroke and large protective width. for the machine tools with large stroke and wide protective width, if the common cover is still used, the disadvantages are more prominent because of the number of sections and large width, and the weight is larger. and the use of double synchronous mechanism with synchronous telescopic guide rail cover can make up for the shortcomings of the ordinary cover, so that the parallel performance of the movement is better, and can ensure the overall performance of the machine tool.
