Moving-Beam Gantry Milling Machine They are primarily made of steel or cast iron. If scratches appear on their surfaces, they should be repaired; otherwise, the damage may worsen and even compromise the machine tool’s performance. During prolonged operation, friction pairs such as those in moving‑beam gantry milling machines experience varying degrees of wear due to differences in friction between the contacting surfaces, which can severely affect machining accuracy and production efficiency. To restore these machine tools and other worn components, metal plates or polymer materials are typically inlaid or replaced. This process not only requires extensive precision machining and fabrication but also involves manual scraping and grinding of the surface finish. Consequently, the repair procedure is complex and the turnaround time is lengthy.

　　When addressing scratches on a moving‑beam gantry milling machine, metal repair materials can be used to restore the damaged areas. Typically, the repair can be completed in just a few hours, allowing the machine to return to service promptly. Practical experience has demonstrated that this approach offers several advantages: it is easy to implement, time‑efficient, delivers high‑quality repairs, and is cost‑effective. Thanks to its exceptional adhesion, superior compressive strength, oil resistance, and wear resistance, it provides a long‑lasting protective coating for components, effectively resolving issues that traditional, non‑removable repair methods cannot address. This enhances the performance of the moving‑beam gantry milling machine, improves component fit and clearance, and, to a significant extent, ensures smooth production operations. As a result, it saves customers substantial time and resources while offering reliable, long‑term support for the continued operation of their equipment.

　　General repair Moving-Beam Gantry Milling Machine The materials used are primarily composed of fine metal or ceramic powders, and are applied in conjunction with curing agents and accelerators for repair. By blending the properties of these materials, a synergistic effect is achieved, resulting in composite materials whose overall performance surpasses that of the individual components. These composites exhibit excellent adhesion, mechanical strength, and chemical corrosion resistance, making them widely suitable for repairing mechanical wear, scratches, dents, cracks, leaks, and casting sand holes in metallic equipment. Additionally, they can be employed for chemical‑resistant protection and repair of various chemical storage tanks, reaction vessels, and pipelines. Overall, the repair process for gantry milling machines with moving beams is as follows:

　　1. Use an oxyacetylene flame to heat the scratched area (control the temperature to avoid surface annealing), and apply oil to the permanently metallized surface, heating until no sparks are produced.

　　2. Moving-Beam Gantry Milling Machine Grind the scratched area using an angle grinder with a grinding depth exceeding 1 mm, and grind the groove along the guide rail. It is recommended to use a dovetail groove (as shown in the figure). Drill holes at both ends of the scratch to deepen it and alter the stress state. Finally, clean the surface with degreasing cotton swabs moistened with anhydrous ethanol.

　　3. Apply the mixed repair compound to the scratched surface, ensuring even and complete coverage of the scratch to guarantee strong adhesion between the material and the metal substrate. Then spread the material over the entire repair area and press repeatedly to ensure thorough filling and achieve the desired thickness, slightly exceeding the rail’s surface level.
