Carbon steel, Stainless steel, High-strength steel, Aluminium, Copper

Regarding to high-precision requirements , We now can ensure that the thickness tolerance to +/-0.001mm .Therefore ,to inner circle ,its tolerance can be achieved to H13 .All inspections of high precision knife are made in the constant temperature room

All of our slitter knife , Spacers , are 6 times heat treatment

With the increasing requirements on the precision of sheet metal processing , We have developed ultra-high-precision cutting tools ,only the precision milling tools can match with its accuracy so far +/-0.001mm thickness tolerance and Ra0.1U surface roughness are our common standards .By using our technique and expertise ,We can meet customers high tolerance requirements in regard to thickness, parallelism ,flatness and so on
