Principle and advantages of Mineral casting base with Hydrostatic guideway

       Mineral casting is widely used in high-end machine tools due to their unique mechanical properties, especially damping effect and thermal performance. From the perspective of the high-end market situation in recent years, the application of mineral casting structural components has been increasing. More and more favored by internationally renowned high-end machine tool manufacturing enterprises.

        Hydrostatic guideway is an inevitable demand for the development of machine tool equipment from low-end to high-end! The process of shifting the transmission mode from hard rail to linear rail and hydrostatic guideway. Hard rails are constrained by wear and speed efficiency, while wire rails solve wear and efficiency issues, errors caused by fitting factors still exist! Hydrostatic guideways have solved problems such as wear, limited speed, and changes in geometric accuracy with their unique structure and form, and have gradually been widely used. However, due to the complexity and high cost of the system, the widespread use of hydrostatic guideway is also constrained!

      After long-term research and extensive experiments, Shandong Nano Advanced Material Technology Co.，Ltd. has finally broken through this technological bottleneck and successfully achieved the combination of "mineral casting body made lead surface" and corresponding static pressure slider hydraulic station to form a mineral casting static pressure guide rail module. This greatly improves the performance of the Hydrostatic  guideway, especially the operating accuracy.

       Inject pressure oil between moving parts to create pure liquid friction, without friction or wear; And due to the damping effect of the liquid, there is no crawling state. Lubricating oil with a certain pressure is input into the oil chamber on the guideway surface through a throttle, which forms a load-bearing oil film and puts the guideway surfaces in a pure liquid friction state.The change in guideway speed has little effect on the thickness of the oil film, and the change in load has little effect on the thickness of the oil film. The friction coefficient of liquid friction is only about 0.005, and the oil film has good vibration resistance.

      According to user needs, various structural forms of static pressure guide rails can be designed, and corresponding static pressure sliders can be selected. We provide static pressure guide rail modules with mineral casting structures, greatly reducing customer workload and improving work efficiency.
