Most of the machine tool guide rails are made of steel or pig iron. Such guide rails should be repaired if they are scratched. Otherwise, the scratches will expand and even endanger the application of the machine tool. The machine tool guide rail and its friction pair, in the whole process of long-term application, because there are different levels of friction between the two surfaces, the surface of the friction pair will cause different levels of damage, which will harm the machining accuracy and productivity of the machine when it is more serious. .


For the repair of machine tools and other damaged locations, metal sheets and fiber materials are generally used for inlaying or dismantling. Not only must a lot of precise production, processing, and manufacturing be carried out, but also manual scraping of the production and processing surfaces must be carried out, and the repair work is in progress. There are many technological processes and a long construction period. The international polymer material 2211F metal repair raw materials are used to repair the scratches on the rails of the gantry milling machine. It only takes a few hours to repair the scratches on the rails and contaminate the rails and put them into use.


The key method of CNC lathe guide rail repair for gantry machining center manufacturers. Practical experience has proved that this method is easy to operate, saves time and effort, and is cost-effective and low-cost. Using its unique adhesion, excellent tensile strength, acid and alkali resistance, and abrasion resistance, it can show a long-term protective layer for components, and can reasonably handle large and medium-sized machinery and equipment that cannot be disassembled due to traditional The problems that cannot be handled by the overhaul method have improved the characteristics of the machinery and equipment, improved the clearance between the components, and ensured the normal operation of all production and manufacturing to the greatest extent, saving a lot of time and assets for customers, and for the company All the normal operation of machinery and equipment has shown a long-term excellent guarantee.

In the case of a gantry milling machine, attention should be paid to the clearance method of the rack and pinion transmission system in the machine tool application.


For large and medium-sized CNC machine tools with long schedules at work, such as large and medium-sized gantry milling machines, ball screw drive systems are not suitable for fitness exercises. Generally, rack and pinion transmission systems are used to complete parallel-line knife fitness exercises. . The rack and pinion transmission system also has the same backlash as the transmission gear, so there is also the problem of clearing the gap.


When the load is small and the cutting force is not large, the gear rack can choose the double-piece thin transmission gear mis-tooth regression analysis method, and the left and right sides of the tooth groove of the gear rack are closely attached to the left and right sides of the gear rack to clear the gap. However, the regression analysis method of the double-piece thin transmission gear's wrong teeth cannot meet the heavy-duty working standard of large and medium-sized machine tools.
