Carbide circular saw blade purchase and correct use
4, repair the saw blade must not change its original angle, to avoid partial hot flashing of the cutter head, it is best to professionally repair the grinding5.
1. Saw blades of different specifications and uses have different cutter head angles and base forms, so try to use them according to their corresponding occasions;
2. The size and shape accuracy of the spindle and the clamp of the equipment have a great influence on the use effect. Check and adjust before installing the saw blade. In particular, the factors affecting the displacement and slippage caused by the contact surface between the splint and the saw blade must be eliminated;
3, pay attention to the working condition of the saw blade at any time, abnormalities, such as vibration, humming, and the surface of the processing surface, must be stopped and adjusted in time, and repaired in time to maintain the peak profit;
4, repair the saw blade must not change its original angle, to avoid partial hot flashing of the cutter head, it is best to professionally repair the grinding
5. The saw blades that are not used for a long time should be hung vertically, avoiding the flat lay for a long time, and should not be placed on the object stack. The cutter head should be protected from collision.
6. The equipment itself should have good mechanical properties, the installation is fixed firmly, no vibration, etc.;
7. The surface of the flange should be clean, flat and intersect perpendicular to each other.
8. The diameter of the flange should be equal to or greater than 1/3 of the diameter of the saw blade used. The flange is too small, even if the best saw blade on the market is used, unsatisfactory results will occur.
9. The main shaft of the mechanical equipment should be flat and straight, the tolerance is not lower than the national standard, and the national standard of the tolerance of the main shaft is 0.01mm.
10. The saw blade has a blunt feel, and it should be repaired in case of emergency. When grinding, the diamond wheel with appropriate particle size should be selected. At the same time, the coolant should be used together. The original cutting angle should be maintained after the grinding, the back angle and the sawing board should be At the same time, grinding and adjustment should be carried out in order to achieve satisfactory results. At present, there are many grinding equipments on the market, and the precision and grinding conditions of the equipment itself are not up to the requirements, let alone the good products can be repaired.
11. Before using the new or repaired saw blade, it should be idle for one cycle, then check if the saw blade is installed securely to prevent the saw blade from slipping.
12. The sawhole reaming should not exceed the original aperture of 15mm. Since each saw blade manufacturer has adjusted the saw blade stress according to its diameter before the saw blade leaves the factory, otherwise the saw blade cutting effect will be affected. .
13. Choose a reasonable number of teeth, which is more conducive to the cutting effect and the extension of the life of the saw blade.
