Performance characteristics of slitting blades

The blade of the longitudinal shear machine uses a high-precision grinder to fine grind the edge, with high processing precision and high finish to achieve the mirror effect (Ra≥0.012). The edge is sharp, no breaking edge, no rolling edge phenomenon. The section of the cut needle is smooth, smooth, no hairless puncture, no barb phenomenon. Select 0.6um subfine crystalline hard alloy powder after precision molding by high temperature and low pressure sintering, the product internal microstructure is good, effectively reduce the micro pores in the alloy, improve the density, avoid the edge in the fine grinding and use of the phenomenon of edge breakage, improve the finish of the cutting section.
