in recent years,according to the different characteristics of toliet paperroll long saw imported from Taiwan,Italy,the United Stated,we choose the materials:W18Cr4V,Japan SKH-71,Germany K10,D2,LD and other imported materials,to develop and produce cut the circule cutter with high wear-resistant awake and anti-rust.with the grinding wheel(good grain-size,soft and moderate)developed by our Company,making grind knife-edge sharp and can achieve higher accuracy.the reby cutting out paper with no edges,no trace,no black phenomenon.Rewinding punching machine supporting the whole strip,the fixed knife using CNC open tooth,a tolerance of parallelism between the 0.01,so as to ensure the shot hole quasi uniformity.
the specification of grinding wheels:
100*20*18.5  
100*20*20  
100*30*16.5
100*20*10
100*20*16.5
