1. Trial operation of the new saw blade.
In order to prolong the service life, the metal circular saw and the new saw blade (the new unused saw blade or the saw blade after each grinding) have a more sufficient running-in process, and the reduction is reduced within 10 minutes after the cutting operation starts. The feed rate is very necessary.
2. Cutting and feeding speed.
Cutting speed depends on the cross section and toughness of the workpiece to be cut. For stainless steel, which is difficult to cut and has high toughness, a slower speed is very helpful to increase the service life of the saw blade. For some iron-based materials with relatively low toughness, the speed of the saw blade can be increased accordingly.
3. Grind the saw blade in time and correctly.
Pay attention to the working condition of the saw blade at all times. If there are abnormalities such as vibration, noise, and material removal on the processing surface, it must be stopped in time for adjustment, and timely grinding to maintain sharpness. Re-grind the saw blade promptly and correctly to maximize the effectiveness of the saw blade.
4. Add suitable coolant.
Because of the high temperature generated during cutting, the saw blade may be deformed. There is no coolant, which not only affects the life of the saw blade, but also the cutting effect is not ideal. So, please add coolant.
5. Observing the sawdust allows you to roughly judge the current performance status of the saw blade.
1) The sawdust is very fine or powdery, indicating that the cutting pressure is too small.
2) Thick and soft sawdust, which means cutting overload.
3) The sawdust is a long spiral filament, which means it is in good condition.
4) If the feed speed is increased, a thicker tooth should be selected accordingly.
