What are the factors that cause excessive burrs in high-speed circular saw machines?

       High-speed circular saw machineWhen using the saw blade for a certain period, it needs to be re-ground through redesign, which not only helps extend the lifespan of the saw blade but also, under normal circumstances, high-speed circular saw blades can be ground two to three times. The specific issues need to be determined based on the actual usage conditions of the enterprise.

1.High-speed circular saw machineWarning for saw blade grinding

When should circular saws, saws, and blades be worn? In most cases, we can judge from various situations, such as the color of the iron chips, the quality of the workpiece, the efficiency of the saw blade, etc.

1. The color of the iron chips cut by the saw becomes heavier.

When the color of the iron chips changes after the circular saw blade cuts the workpiece, such as becoming heavier (turning blue), the saw blade status should be checked or the equipment should be inspected, and then the specific parameter changes should be reviewed, such as the number of cuts (square feet), to determine whether grinding is necessary based on the actual situation.

2. The sound of the saw blade cutting is abnormal.

During the sawing and processing production process, if there are abnormal sounds from different parts of the saw blade, such as being rough or having a "click, click" sound, the condition of the saw blade should be checked. In most cases, this is an important signal that grinding is needed.

3. The quality of the cut workpiece.

When the circular saw blade cuts the workpiece, its quality should not vary too much, with a relatively smooth surface and no burrs. If it is found that the surface of the workpiece suddenly becomes less smooth, or if burrs are present on the same side, or if the iron pieces stick and do not fall off, it can generally be judged that the saw blade needs grinding.

2. Grinding treatment

High-speed circular saw machineThe grinding of the saw blade should be carried out by professional grinding manufacturers or suppliers of circular saw machines and should not be operated by oneself, otherwise, it may completely damage the saw blade.

High-speed circular saw machineWhat are the factors that cause excessive burrs?

A. Check the magnetic powder clutch.

Cause analysis: The magnetic powder clutch of the high-speed CNC circular saw plays a role in protecting and stabilizing the circular saw blade, making the cutting more accurate and effective. If there is a problem with the magnetic powder clutch, it will lead to unstable operation of the circular saw blade, resulting in various cutting issues.

Solution method: Stop the equipment and conduct a series of checks based on the specific actual situation in China and the usage instructions of the enterprise. It is recommended to invite professional maintenance personnel to investigate the accident.

B. Incorrect installation of the circular saw blade.

Cause analysis: When installing or replacing the circular saw blade, if there is a loose screw or incorrect flange, it will cause the circular saw blade to wobble during the cutting process.

Solution: Check the condition of the equipment one by one, the fastening situation between parts, and inspect the flange and other components.

The saw blade of the CNC circular saw itself is incomplete.

Cause analysis: During the installation process of replacing the circular saw blade, the condition of the saw blade was not carefully checked, such as cracks in the saw blade, gaps in the teeth, and other issues.

Solution method: Before using the circular saw blade, a check should be made on the saw blade itself, and defective saw blades should not be installed for use.

D. The circular saw blade needs grinding.

Cause analysis: The circular saw blade has a certain usage time, exceeding the repair time. If not ground, the cutting and surface burrs of the workpiece will be unstable or have poor parallelism, which can lead to irreversible accidents such as tooth shape explosion.

Solution: Timely maintenance and polishing of the saw blade of the high-speed CNC circular saw; when repair polishing is needed, the saw blade should not be replaced, and preparations should be made in advance.
