In order to prolong the service life, the metal circular saw has a sufficient running-in process with the new saw blade (new unused saw blade or saw blade after each grinding), and it is necessary to reduce the feed rate within 10 minutes after the start of the cutting operation. of.
1. Test run the new saw blade.
In order to prolong the service life, the metal circular saw has a sufficient running-in process with the new saw blade (new unused saw blade or saw blade after each grinding), and it is necessary to reduce the feed rate within 10 minutes after the start of the cutting operation. of.
2. Cutting and feeding speed.
The cutting speed depends on the section and toughness of the workpiece being cut. For stainless steel, a material that is difficult to cut and has high toughness, the slow speed is very beneficial to improve the service life of the saw blade, while for some iron materials with relatively low toughness, the speed of the saw blade can be increased accordingly.
3. Grind the saw blade correctly and in time.
Pay attention to the work of the saw blade at any time, such as abnormal conditions such as vibration, sound, feeding of the processing surface, etc., it must be stopped and adjusted in time, and it must be ground in time to keep it sharp. Timely and correct regrinding of the saw blade maximizes the efficiency of the saw blade.
4. Add a suitable coolant.
Due to the high temperature generated in the cutting process, the saw blade may be deformed, and there is no coolant, which not only affects the service life of the saw blade, but also the cutting effect is not ideal. So, please add coolant.
5. Observe the sawdust, allowing you to roughly judge the current efficiency 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, indicating cutting overload.
3) The sawdust is long spiral, which means it is in good condition.
4) If the feed rate is increased, thicker teeth should be selected.
