the life of high speed steel circular saw blades


In order to maximize the reduction of the consumption of high-speed steel circular saw blades, each blade reduces cutting costs, increase plant productivity, the actual situation of the following applications for the proposal wants to follow:
1, the new blade test run:
To ensure long life, so that masonry saw blades   circular saws with a new blade (or replace the blade after each grinding) have a full running-in process, the cutting begins within 10 minutes, reducing the feed rate is very necessary The. The next 10 minutes before gradually speed up;
2, cutting and feed rate:
Cutting speed depends on the material being cut sections and toughness, this is difficult for cutting stainless steel, high toughness of the material, the slower the speed is very beneficial  concrete core bits to increase blade life. When the material cross section is small, can be an appropriate increase in engine speed;
3, correct and timely grinding blade:
Blade during operation, due to the role of external forces, the blade pitch and yaw rate, stress, etc. has changed, so there will be larger road saws; surface roughness, clip blade and other phenomena; timely grinding blade, serrated blade to re-raise the angle, pitch accuracy, high-speed steel circular saw blades will increase the use of results;
4, you can judge sawdust observe the  cup grinding wheels current state of cutting blade;
a, very fine sawdust or powdered cutting pressure indicates the size;
b, of a soft cut sawdust that overload;
c, long spiral wire sawdust expressed in good condition;
