The disadvantages of traditional cast iron-cast iron and cast iron-quenched steel guide rails are that the static friction coefficient is large, and the dynamic friction coefficient changes with the speed, the friction loss is large, and the crawling phenomenon is easy to appear at low speed/(1-60mm/min/), thus The positioning accuracy of the moving parts is reduced, so it is no longer used on other CNC machine tools except for economical CNC machine tools.
However, the rolling guide has poor vibration resistance and higher protection requirements. Static pressure guide rails can be divided into hydrostatic pressure guide rails and gas static pressure guide rails. There are mainly three kinds of guide rails for cnc machining center, and the difference between these three kinds of guide rails is relatively large, so if you need to choose the guide rails of cnc machining center, it is best to have a detailed understanding of these three guide rails in advance, so that you can better I have chosen the guide rail for my cnc machining center.
The disadvantage is that the structure is complicated, the oil supply system is required, and the cleanliness custom car Interior Suppliers of the oil is required. The sliding guide has the advantages of simple structure, convenient manufacturing, good rigidity and high vibration resistance.
The so-called cnc processing is also called numerical control processing, which refers to a kind of processing that the programmers use the computer to program the work orders that need to be processed and then are operated by the cnc processing operator is called cnc numerical control processing.
