When high-speed steel HSS circular saw blades are sawing metal materials, they often encounter some small problems. The saw blade manufacturer has a lot of experience to say that high-speed steel saw blades often encounter problems and solutions when sawing.
The reason why the high-speed hacksaw saw the workpiece is not straight and the length is inconsistent:
1. During cutting, the feeding frame bumps and shakes and the positioning is not accurate, and the machine is not calibrated when assembling.
2. Use high-speed steel saw blades that are deformed under pressure.
3. The deformation of the cut data is not standardized.
4. The machine cuts the knife too fast and the number of teeth is incorrect.
Solution:
1. Always check the condition of the material rack and the positioning ruler, and correct the level of the machine.
2. Since the high-speed steel saw blade has a hammer, it should be erected and placed to prevent gravity from being pressed.
3. Select good raw materials and standardized materials.
4. Select the correct cutting speed according to different materials, and select the number of teeth according to the wall thickness of the material.
Reasons for abnormal noise when sawing with high-speed steel saw blades:
1. The teeth should not be sharp or broken.
2. The workpiece clamp is not tight.
3. Chips are attached to the teeth.
Solution:
1. Grind the saw blade from scratch.
2. Check the workpiece clamping equipment.
3. Stop the machine and check whether the number of cut teeth is applicable.
