Precautions when cutting metal circular saw blades with cold saws

The cold saw metal circular saw blade needs to be adjusted and set up in cutting. Some operations on the details can effectively improve the cutting effect and extend the service life of the cold saw metal circular saw blade, including the stability and workpiece during cutting. quality.

1. Preparatory work in the early stage

When using cold saw metal circular saw blades, preparatory work must be done in place, especially the installation of the saw blades.

Preheating and idling must be carried out before use. The so-called preheating and idling refers to the operation of the cold saw metal circular saw blade for a period of time after installation and before use (no need to cut any material, just empty work) , lasts about 1 minute to 10 minutes (the details need to be determined according to the actual situation), if it is a hot climate, it is necessary to spray oil mist or bring water; this will help to enhance the sharpness of the saw blade, if it is just installed Just carry out the cutting operation directly, which will easily cause damage to the metal circular saw blade.

2. Some precautions when sawing

When cold-sawing metal circular saw blades, you must pay attention to some problems. Do not work carelessly, which may cause permanent damage to equipment and saw blades.

1. After the idling is completed, check the distance between the cold saw metal circular saw blade and the cutting material (commonly known as the saw blade returning to zero), and do not start the operation when the saw blade is in contact with the material.

2. If it is found that the material shakes during the cutting process, the operation must be stopped, and the cutting operation can only be carried out after checking the faults and arranging them. (During the operation, do not move the material, and it is forbidden to touch the saw blade with your hands).

3. When cutting, if you find that the metal circular saw blade of the cold saw has slight shaking or teeth jamming, you must immediately stop the equipment. It is likely to be caused by a certain part being stuck or a problem with the magnetic powder clutch.

4. If you find problems such as deceleration or reduction in cutting quality during sawing, you should stop running, check the nut or the cutting depth is too large, and the working speed is too fast, and check and adjust in time.

When using a cold saw metal circular saw blade for cutting, it is necessary to carefully check the important parts.
