With the increase of use time, all parts of the machine tool will wear, and the guide rail is no exception. If the operator does not use the machine tool correctly, and often causes impact, overload and other operating errors, will lead to guide rail wear, to achieve no wear or reduce wear of the machine tool guide, can be carried out from the following aspects:
1, reduce pressure : by increasing the contact area of the guide rail or using mechanical hydraulic unloading and other methods to reduce the specific pressure of the guide rail surface, so as to reduce wear .
2, change the nature of friction : use rolling friction instead of sliding friction, or ensure sufficient lubrication, avoid dry friction or semi-dry friction, to reduce wear .
3, the use of wear-resistant coating: the application of wear-resistant coating on the guide rail can improve its wear resistance and reduce friction and wear.
4, strengthen protection : in operation and use, pay attention to prevent chips, abrasive particles or chip liquid scattered on the guide rail surface, otherwise it will cause increased wear, abrasion and rust of the guide rail, you can install protective cover to prevent dust, cutting chips and other impurities into the guide rail, reduce wear caused by impurities .
5, regular lubrication : should choose the appropriate lubricating oil or grease, and replace it at the specified interval, to ensure that the guide rail is always in a good state of lubrication .
6, keep the working environment clean : reduce dust, metal chips and other impurities, and timely clean the impurities on the surface of the guide rail to avoid accelerated wear of impurities.
7, optimization design and material selection : by designing such as curved slider track, increasing the number of balls, reducing the contact area, etc., the friction coefficient and wear can be reduced.
8, reasonable selection of guide rail materials : choose the right guide rail materials, such as static guide rail, through oil film isolation to reduce friction and wear .
9, regular inspection and maintenance: regularly check the wear of the guide rail, timely repair or replacement, in order to maintain the good condition of the guide rail.
These are some common methods, but to achieve true wear-free may be unlikely, because friction and wear are inevitable natural phenomena. However, the above measures can greatly extend the service life of the guide rail and reduce the degree of wear, and improve the efficiency and accuracy of the machine tool guide rail.
