High-Precision Slitting Round Blade Disc Knife - China Suppliers for Steel and Non-Ferrous Metal Factories
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, we also meet our customers' higher tolerances for thickness, parallelism, flatness, outer and inner rings.
Rubber Sleeve & Blade Bushing Options
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).
Blade Sleeve Materials
- S45C — Most commonly used blade sleeve material
- S50C — High-strength option for demanding applications
- 65Mn — Superior spring steel for resilience and hardness
The purpose of the blade bushing is to create 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 ranges between 0.9mm ~ 100mm. The thickness tolerance of the blade casing is also controlled within 0.003mm/mt.
💡 Weight Reduction Option: In order to reduce weight, we can also produce aluminum spacers using AL7075. The thickness tolerance is also controlled within 0.003mm/mt.
