When using the 115*1*22 cutting disc , not only must it be used for its use, but the installation of the cutting piece is also a very important task. How to install this type of cutting piece? Next, the manufacturer specializing in the production of cutting sheets will give you a summary of how to install the cutting piece?
1. Before installing the cutting piece, it must be calibrated for its safe working line speed. The grinding wheel with unclear or no mark must be re-tested by rotation.
2. Before installing the cutting piece, tap the grinding wheel with a wooden hammer. If the grinding wheel (especially the ceramic grinding wheel) has a dumb sound, it indicates that there may be cracks in the grinding wheel. This kind of grinding wheel cannot be used.
3, 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.
4. 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.
5. After the cutting piece is installed, it must be statically balanced before it can be loaded onto the grinding machine. When the yaw is too large, the grinding wheel should be reinstalled. Special attention should be paid to the installation of grinding wheels on grinding machines. Work under high-speed rotation conditions, should be carefully checked before use, no cracks are allowed. The installation must be secure and should be statically adjusted to avoid personal and quality accidents.
6. Between the inner hole of the cutting piece and the outer circle of the grinding wheel shaft or the flange, it should not be too tight. Otherwise, it will be heated and expanded during grinding. It is easy to crack the cutting piece, and it should not be too loose. Otherwise, it will easily lead to eccentricity and loss of balance. Causes vibration. Generally, the matching clearance is 0.1~0.8mm, and the high speed clearance is smaller.
