When a cold saw blade cuts metal, the heat generated by the cold saw blade's teeth when cutting the workpiece is transferred to the sawdust through them, and the workpiece and the saw blade remain cool. This cutting method is called cold sawing. Cold sawing is different from friction sawing, in which the workpiece and the friction saw rub against each other, causing the friction saw and the workpiece to have very high temperatures during the sawing process.
Advantages of cold saw blades:
Compared with ordinary metal cutting friction saws, the advantages of cold saw blades are as follows: high precision of the workpiece, no burrs, and reduced intensity of the next process; the workpiece will not affect property of the material due to the high temperature generated by friction; the frequency of fatigue among workers is lower and the sawing efficiency is higher; there is no spark, no dust, and no noise during the sawing process; it is beneficial for energy conservation and environment protection.
Materials cut by cold saws:
Mainly used for cutting metal, such as steel, aluminum, copper, iron, etc.
How to use cold saws:
1. Preparation: we need to check whether the saw blade is installed correctly and whether the saw blade is firmly tightened before using a cold saw. At the same time, check whether the blade edge is clean to ensure the cutting quality.
2. Adjust the sawing machine: Fix the material to be cut on the sawing machine, and adjust the cutting depth and angle of the sawing machine to ensure the cutting quality.
3. Start cutting: Turn on the cold saw cutting machine and slowly place the saw blade on the material to be cut to start cutting. During the cutting process, it is necessary to ensure that the saw blade is in the correct position to avoid deviation or shaking.
