In order to minimize the consumption of HSS circular saw blades, reduce the cutting cost per knife, and improve the production efficiency of the plant, the following application recommendations are expected to be complied with:
1. Trial operation of the new saw blade:
In order to guarantee a long service life, it is necessary to have a sufficient run-in process between the circular saw machine and the new saw blade (the saw blade after each grinding replacement) and to reduce the feed rate within 10 minutes of the start of cutting. The next 10 minutes gradually increase the speed;
2. Cutting and feeding speed:
The cutting speed is determined by the cross-section and toughness of the material to be cut, and for stainless steel, which is a difficult-to-cut and toughness material, the slower speed is very conducive to improving the service life of the saw blade. When the cross-section of the material is small, the speed of the machine can be increased appropriately;
3. Grind the saw blade correctly and in time:
During the operation of the saw blade, due to the action of external force, the tooth pitch, yaw, stress, etc. of the saw blade have changed, so the saw path will become larger; rough surface, clipping saw blades and other phenomena; Timely grinding of the saw blade to re-improve the accuracy of the saw blade's saw tooth angle and tooth pitch will improve the use effect of the high-speed steel circular saw blade;
4. Observing the sawdust, you can judge the current cutting state of the saw blade;
a. Very fine or powdery sawdust indicates the size of the cutting pressure;
b. Coarse soft sawdust indicates cutting overload;
c. Long spiral wire sawdust indicates that it is in good condition;
