High-Precision Slitting Round Blade | China Suppliers & Factory for Steel and Non-Ferrous Metal Industries

Product Introduction

We can now guarantee that the thickness tolerance of ± 0.0005mm. For a certain inner circle, the tolerance can reach H3. All high-precision products are tested in a constant temperature room. With the continuous improvement of machining precision of sheet metal, we have developed ultra high precision cutting tools, whose accuracy has so far been matched by precision milling tools.

We can also attach a rubber sleeve to the outer diameter according to the customer's request, so that it can be exported smoothly with the knife to prevent scratches. The rubber sleeve is made of natural primary rubber such as green amine and acrylonitrile butadiene rubber (IRHD: 78~75), and Polyurethane isolation ring (IRHD: 80~85).

The blade sleeve is used to maintain a certain width between the dividing round knife, the upper knife and the lower knife, and to allow horizontal gap adjustment. After forging, machining, heat treatment, and leveling grinding, the hardness reaches 47 ± 2 degrees. Blade sleeve thickness tolerances are controlled within 0.003mm/mt. To reduce weight, aluminum spacers (AL7075) are also available with the same tolerance standard.
