How to Repair Worn Machine Parts?

Parts wear, scratches, and size tolerances account for about 70% of machine parts failure. Most of the equipment parts are made of metal materials. Due to their high strength and hardness, the parts are subjected to vibration, impact, and other compound forces during production and operation, which often leads to a "hard-to-hard" relationship between metal parts.

Part of the impact deformation becomes permanent deformation, the recovery stress is reduced, and the gap is formed, which cannot meet the requirements of the operation, resulting in the wear of the parts with relatively low hardness. The following is the specific method to repair worn-out machine parts.

Traditional repair methods include surfacing welding, thermal spraying, electric brushing, and other processes. Those metal parts that are particularly sensitive to temperature will cause the surface of the part to reach a high temperature, causing deformation or cracking of the part, affecting the dimensional accuracy and normal use of the part, and even causing the shaft to break in severe cases.

Although the brush crossing has no thermal influence, the thickness of the coating should not be too thick, the pollution is serious, and the application is also greatly restricted. The use of polymer materials for repair, the comprehensive performance of the product, and the superiority of machining at any time, not only fully meets the use requirements and accuracy after repair, but also reduces the impact and vibration of the equipment during operation and extended service life.

Because the material is a "variable" relationship, when an external force impacts the material, the material deforms and absorbs the external force, and expands and contracts with the expansion and contraction of the bearing or other components, and always maintains a tight fit with the components to reduce the probability of wear. We call this "shrinkage effect".

In view of the wear and tear of large-scale equipment, "mold" or "matching parts" can also be used to repair damaged equipment on-site to avoid the overall disassembly of the equipment. It can also ensure the matching size of parts to the greatest extent, meet the production and operation requirements of the equipment, and extend the equipment The service life of the company ensures the safe and continuous production of the enterprise.

After repairing, the coating of various machine parts has a strong bonding force and is not easy to fall off. It can also improve the wear resistance, corrosion resistance, high-temperature resistance of the parts, and surface hardness are high. After the repair, the parts will not be deformed, annealed, undercut, and will not damage the substrate or soften.

Moreover, this technology has fast repair speed and low repair costs. After this technology is repaired, it does not need to be turned again, and the dimensional accuracy of various parts can be guaranteed.

(1) Brush-plating coating material is nickel alloy hardness HRC25-60, and its performance is high hardness, wear resistance, high-temperature resistance, and corrosion resistance. The surface temperature of the parts during the plating process is always less than 70 degrees.

(2)The cold welding material is high-hardness stainless steel, with good welding bonding force, low workpiece temperature, no deformation of the workpiece, and high hardness of the welded material.

The wear of machine parts not only affects the working performance of the equipment but also causes machine failure or shutdown in serious cases.
