The difference between the cold and hot cut saw blade can be seen by cutting the material.
Cold Cut Saw Blade
- A circular saw designed to cut metal.
- Transfer the heat generated by cutting to the chips created by the saw blade.
- The cutting surface is smooth and smooth.
Hot Cut Saw Blade
- Commonly known as chopping saw, also called friction saw.
- High-speed cut with high temperature.
- Multi burr.
Cutting Method
Cold Cut
- High speed saw blade rotates slowly.
- Milling the welded pipe.
- No burr and no noise.
- The sawing process produces very little heat.
- Saw blade has little pressure on the steel tube.
- Will not cause deformation of the pipe wall.
Hot Cut
- The ordinary computer flying saw rotates at high speed for the tungsten steel saw blade.
- The contact pipe generates heat to break it.
- High burning marks are visible on the surface.
- A large amount of heat is generated.
- The saw blade has great pressure on the steel tube.
- Resulting in the deformation of the pipe wall and causing quality defects.
