1. Visual inspection method: Place the cut disc on a well lit surface and observe the overall shape of the disc, the flatness of the cutting surface, the smoothness of the incision, and whether there are peeling, cracks, etc. with the naked eye.
2. Measurement and inspection method: Use measuring tools such as calipers, angle rulers, etc. to measure the diameter, depth, angle, slope, etc. of the incision and determine whether it meets the standard requirements.
3. Specific gravity measurement method: Use a specific gravity measuring instrument to measure the specific gravity of standard discs of different materials and discs to be inspected, and determine whether they meet the material requirements.
4. Magnetic particle testing method: Spread the magnetic powder on the incision, observe whether there are cracks, fractures, and other defects after magnetic action.
5. Ultrasonic testing method: Using ultrasonic testing instruments, perform ultrasonic detection on the incision to determine whether there are internal defects or cracks.
6. X-ray testing method: Use X-ray testing instruments to perform X-ray testing on the incision to determine the presence of internal defects and foreign objects.
The above methods can be combined to fully ensure the quality of the cutting disc and ensure that there are no safety hazards during use.
