1. When the cutting temperature is above 600℃, the hardness still does not decrease obviously, and the cutting speed of the saw blade can reach more than 60 meters per minute.
2. It is not easy to oxidize and rust in the air, so it is called Bai Gang.
3. The high-speed steel saw blade grinder can be used repeatedly to grind the blade teeth.
Extended data:
Fenggang saw blade is mainly used for machining or cutting narrow and deep grooves of metal materials such as steel, iron, copper and aluminum with medium hardness. It can also be used for milling nonmetals. High-performance high-speed steel saw blades are mainly used for milling difficult-to-cut materials (high-strength steel such as heat-resistant steel and stainless steel).
The diameter of the saw blade in Fenggang is related to the sawing equipment used and the size of the sawing workpiece. The diameter of saw blade is small, and the cutting speed is relatively low; The diameter of saw blade is large, which has high requirements for saw blade and sawing equipment and high sawing efficiency. Choose the outer diameter of the saw blade according to different circular saw models.
