Wheel hub scratch is a relatively common wheel hub problem. In addition to affecting the appearance, if the scratches on the hub are relatively large, it will also affect the dynamic balance of the hub. At high speeds, the car shakes. Serious car accidents will occur.
Wheel hub scratches are caused mainly by hitting rocks or roadblocks. Because the wheels of the car are made of aluminum alloy. So it’s easier to get hurt. We have different methods for different Wheel hub scratches. But it needs to be processed with the help of a wheel repair machine. A precise wheel repair lathe can efficiently and perfectly repair Wheel hub scratches. The process is more complicated, and I will explain the specific procedure to you in a future article.
Wheel hub scratch often appears on the surface of the wheel hub. First, you need to remove the car wheel for cleaning. It is then installed on the wheel hub straightening machine for deformation detection and refurbishment. Then the alloy wheel lathe can detect the surface of the wheel hub by laser detection. and the software can automatically optimize the curve after the hub shape appears. The the starting point of the tool can use the laser tool setting method. At this time, the wheel hub can be processed. Start machining with a relatively small amount of cutting on a vertical hub lathe often occurs. This step observes whether the probing and the generated machining program conform to the formed surface. Then add the thickness of the cut to the shoulder pads. Different hub lathes target different hubs. So it is better to choose a slightly larger mobile hub lathe.
If it is a small Wheel Hub Scratch, it can be polished. If it is a slightly serious scratch, you can use a metal putty first, and then go through the spray polishing treatment, which can almost achieve a new feeling. There are many shops that provide mirror plating technology.
If the wheel hub is only scratched on the surface, it will only affect the appearance and will not affect the performance of the car tire. But if the primer is exposed after scratching, then you need to pay attention, the scratched position will wrinkle and the scope will continue to expand, and it will rust and corrode after a long time. If the edge of the wheel hub is scratched, it should be repaired in time. If it is serious, the tire will not be in tight contact, causing the tire to leak.
Wheel hub scratch repair process:
- Clean the wheel hub and remove stains;
- For painting and oiling, you can apply tape around the scratched part in the advance to prevent it from being mistakenly applied to other positions;
- After the hub is completely dry, smear it with water-resistant paper dipped in soapy water, polish it with a mixer, and wax it;
- The scratches on the hub can be repaired, but the premise is that the hub has not been seriously damaged. If the hub has been deformed or broken, it cannot be repaired.
Gravity casting, forging and low-pressure precision casting are the three main ways of manufacturing aluminum alloy wheels. Gravity casting has low cost and high production efficiency, but the finished product is prone to bubbles, uneven density, and insufficient surface smoothness. Although the forged products are of good quality, the manufacturing cost is high and the yield is low. The low-pressure precision casting method has good formability, clear outline, uniform density, smooth surface, controllable cost, and high yield. It is the most important way to manufacture aluminum alloy wheels today.
Wheel hub scratch repair is a complex process. If you want to do it easily, you need to use a highly automated and precise car wheel lathe. Different wheel lathes can repair wheels of different sizes, shapes, and heights. Tai’an HAISHU is a manufacturer specializing in the production and sales of wheel repair lathes.
