The
high efficient metal abrasive disc is widely used for its excellent performance. The grinding disc plays an important role in industrial production. The correct installation of the cutting piece is directly related to the safety in the production process. Now, simply ask what problems should be paid attention to when installing the lower grinding disc:
1. Before installing the grinding disc, the marking of the cutting piece must be checked first. The high efficient metal abrasive disc with unclear or no marking must be re-tested by the rotation, otherwise it is easy to be confused.
Second, we must understand the working line speed of the high efficient metal abrasive disc. If the cutting piece with a working line speed of 50m/s is installed on a machine with a working line speed of 80m/s, it will easily break.
3. Before installation, use a wooden hammer to tap the high efficient metal abrasive disc. If a crisp sound is produced, the quality of the ultra-thin cutting piece is qualified. Otherwise, there may be cracks in the grinding disc. This type of grinding disc cannot be used.
Fourth, the flanges sandwiched on both sides, the shape of the same size. The diameter of the flange is generally half of the diameter of the resin grinding disc cutting piece, the inside should have a concave groove. Between the end face of the high efficient metal abrasive disc and the flange, to be padded An elastic cardboard or leather, oil-resistant rubber gasket with a thickness of about 1 to 2 mm, the diameter of the gasket should be slightly larger than the outer diameter of the flange.
5. The flange screws should be tightened symmetrically in order to make the clamping force evenly distributed, but the force should not be too strong, otherwise one side will be fractured.
6. After the high efficient metal abrasive disc is installed, it must be idle for one minute. This is done for the last time to check the quality of the super-grinding disc.
After the high efficient metal abrasive disc is installed, it must be carefully inspected before use. It should work under high-speed rotation conditions. The installation must be secure and balanced to avoid personal and quality accidents caused by cracks in some quality problems due to high-speed operation.
