promising cutting manufacturing machined blade

Slitter blade is high carbon tool steel manufacturing overall, the allowable cutting speed is about 5 m / min.
In the use of alloy tool steel, slitting machine blade cutting speed progress to about 8 m / min, using high-speed steel, and  wet saw blades more than twice the progress to the use of carbide, the progress of high-speed steel off than with more than twice the machining the workpiece surface quality and dimensional accuracy greatly improved.Because the price of high-speed steel and carbide is more expensive, slitting machine blade thrown welding and mechanical clamping structure.
Slitting machine machinery manufacturing  concrete ring saw top blade is used cutting tools, also known as circular cutting blade.
The outer surface of the processing of various tools, including turning, planing, milling cutters, broaches and rasp outer surfaces, etc.; hole cutting tools, including drills, reamers, boring tools, reamers and the inner surface broaches, etc.; thread processing tools, including taps, dies, automatic opening and closing of thread cutting head, thread  hss drill bits turning and thread milling cutters; gear cutting tools, including hobs, shaper cutters, shaving cutters, bevel gear cutting tools, etc.; interception tools, including inserts tooth circular saw blades, band saw, bow saw, cut off saw milling turning and so on. Late Warring States period (third century BC), because grasp carburizing technology, made of copper tools.
