JASU Precision Machine: How to Select the Proper Brand Guideway of CNC Machine Tools

As an important part of the feed system, the performance of the guide rail of CNC machine tools will have a decisive impact on the machining accuracy and bearing capacity of the lathe. Different lathes have different requirements for the guide rail. Compared with the guideway requirements of ordinary machine tools, the guideway of CNC machine tools has the characteristics of no creeping at low speed and no vibration at high speed. So how should users choose the right guide rail? Now let's introduce the common guide rail forms.

1、 Sliding guide rail

The sliding guide rail is simple in structure, strong in rigidity, earthquake resistant and easy to manufacture, and is widely used in general machine tools. Generally, in order to improve the wear resistance and accuracy of the guide rail, the surface of the guide rail needs to be processed after quenching.

2、 Hydraulic guide rail

Hydrostatic guideway is commonly used in machining center of CNC machine tools. It has the advantages of small friction coefficient and low power consumption, and the oil film thickness is almost independent of speed. However, the disadvantages are that the structure is relatively complex, the filtering requirements for hydraulic devices are relatively high, and the manufacturing cost is relatively high.

3、 Rolling guide

As the name implies, the rolling guide is to install a rolling element similar to a ball on the working surface of the guide, so that the friction coefficient of the guide becomes very small. The positioning accuracy is also high, relatively stable, and the service life is long. The main disadvantage is poor seismic resistance. In recent years, with the continuous development of CNC machine tools, rolling guides, especially linear guides, are widely used.

The above brief introduction of several different types of CNC machine tool guide rail, how to choose the appropriate guide rail, in fact, depends on the specific work needs.
