Straightening of steel cutting machine

The cutting edge is a very important component in the straightening and cutting machine. It has played a crucial role in the use of steel straightening and cutting machine, which directly affects the working efficiency of the straightening machine.
First of all we have to say is the straightening of steel cutting machine cutting edge of the choice. Cutting edge to note that there can be no cracks, burrs, sharp corners, blade surface shall not have scratches, shall not have chipping and Ma pit and other defects. If there is such a problem cutting edge, not only will affect the efficiency of steel straightening machine, but also easy to hurt the machine itself.
Second, is the knife blade set the diameter of the knife set. What we usually ask is greater than the diameter of the cut bar. It is different for cold drawn bars and hot rolled bars.
Finally, the need to pay attention to is that the straightening of the cutting machine cutting edge must be selected strength and toughness are better, it is best to achieve HRC55 above the hardness, so as to ensure that the steel straightening cutting machine cutting effect and processing efficiency.
