What should we pay attention to when installing ultra-thin cutting discs? JUMA ABRASIVE CO.,LTD tell you the Precautions of ultra-thin cutting disc installation.
1. Before installing the ultra-thin cutting discs, the marking of the cutting disc must be checked first. The grinding wheel with unclear or unmarked mark must be re-tested by the rotation, otherwise it is easy to be confused.
2, it is necessary to understand the working line speed of the ultra-thin cutting discs. If the cutting disc with a working line speed of 50 m/s is mounted on a machine with a working line speed of 80 m/s, it is easy to break.
3. Before installation, use a wooden hammer to tap the cutting discs. If a crisp sound is produced, it means that the quality of the ultra-thin cutting disc is qualified. Otherwise, there may be cracks in the grinding wheel. This type of grinding wheel cannot be used.
4, 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 wheel and cutting wheels, the inside should have a concave groove. Between the end face of the grinding wheel 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 large, otherwise the surface will be fractured.
6. After the ultra-thin cutting discs is installed, it must be idle for one minute. This is done for the last time to check the quality of the ultra-thin cutting disc. In the process of idling, those cutting blades with quality problems are broken. Because it works under high-speed rotation conditions, it should be carefully inspected before use. The installation must be reliable and should be adjusted by static balance to avoid personal and quality accidents.
