China Slitting Round Blade Suppliers - High-Precision Disc Knives for Steel and Metal Processing Factory
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. ± 0.001mm thickness tolerance, and Ra 0.1μ surface roughness are our routine standards. Using our know-how and expertise, we also meet our customers' higher tolerances for thickness, parallelism, flatness, outer and inner rings.
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), Polyurethane isolation ring (IRHD: 80 ~ 85). The blade sleeve material is S45C, S50C, 65Mn, etc., of which S45C are commonly used materials. The purpose of the blade bushing is to make a certain width between the dividing round knife, the upper knife and the lower knife and the horizontal gap adjustment; commonly used blade sleeve thickness between 0.9mm ~ 100mm (grinding material, after forging, machining, heat treatment, leveling grinding), the hardness of 47 ± 2 degrees, the thickness of the blade casing tolerances are also controlled within 0.003mm/mt. In order to reduce weight, we can also produce aluminum spacers using AL7075, with thickness tolerance also controlled within 0.003mm/mt.
