To what extent does Manhart (Guangdong) CNC Machine Tool Co., Ltd.’s rolling and bending wheel wear out and need to be replaced?

The degree of wear of the roll bending wheel that needs to be replaced mainly depends on several factors: the material of the roll bending wheel, the operating environment, the working load, and the requirements of the roll bending process. Generally speaking, when the wear of the rolling and bending wheel reaches a certain degree, which affects the machining accuracy or product quality, it is necessary to consider replacement.
Here are some guidelines for determining whether the bending wheel needs to be replaced:
1. * * Surface wear * *:
When the surface of the bending wheel is severely worn and there are obvious pits, scratches, or burrs, these will affect the accuracy of the bending and product quality. At this point, consideration should be given to replacing the bending wheel.
2. * * Size deviation * *:
Regularly check the outer diameter, inner diameter, and width of the bending wheel using measuring tools such as vernier calipers and micrometers. If the measurement results show that the size deviation of the bending wheel exceeds the allowable range, it may indicate that the bending wheel has been excessively worn and needs to be replaced.
3. * * Roundness error * *:
Use a dedicated roundness measuring instrument or laser rangefinder to check the roundness of the rolling wheel. If the roundness error exceeds the range required by the process, the rolling and bending wheel may need to be replaced.
4. * * Processing quality decline * *:
If it is found that the quality of the product processed with the rolling and bending wheel has decreased, such as increased surface roughness, inaccurate bending angle, etc., this may be caused by the wear of the rolling and bending wheel. At this point, the wear of the bending wheel should be checked and replacement should be considered.
5. * * Service life * *:
Based on the usage of the bending wheel and the manufacturer’s recommendations, an expected service life can be set. When the bending wheel reaches or exceeds this expected lifespan, even if there are no obvious signs of wear, it is recommended to replace the bending wheel to avoid potential machining problems.
6. * * Security considerations * *:
If cracks, fractures, or other safety hazards are found on the bending wheel, it should be immediately stopped from use and replaced in a timely manner.
In summary, there is no fixed standard for the timing of replacing the bending wheel, but it needs to be judged based on actual situations and usage experience. To ensure machining accuracy and product quality, it is recommended to regularly inspect and evaluate the rolling and bending wheels, and decide whether to replace them based on the evaluation results. It is also very important to follow the manufacturer’s maintenance recommendations and usage guidelines.
