Ultra-thin cutting blades are widely used for their excellent performance. China cutting disc for metal play an important role in industrial production. The correct installation of cutting blades is directly related to the safety in the production process. Now simply the ultra-thin cutting blades What issues need to be paid attention to during installation:
1. Before installing the ultra-thin cutting piece, the marking of the cutting piece must be checked first. The grinding wheel with unclear or no mark must be re-tested by the rotation, otherwise, it is easy to be confused.

2, we must understand the working line speed of ultra-thin cutting blades. 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 break easily.

3. Before installation, use a wooden hammer to tap the cutting piece. If a crisp sound is produced, the quality of the low price disc for metal 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 cutting piece, 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 strong, otherwise, one side will be fractured.

6. After the ultra-thin cutting piece is installed, it must be idle for one minute. This is to test the quality of the ultra-thin cutting piece.
After the cutting piece 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.
