About Our Industrial Round Cutting Blades

ShengAo Industrial Round Cutting Blades are precision-engineered circular knives designed for a wide array of industrial cutting machines. These blades serve as critical components in converting and processing equipment, used to cleanly and efficiently slice through various sheet and roll materials. Available in both single and double-edge designs, they are engineered for maximum precision, durability, and consistent performance in high-speed production environments. From small-scale machinery repairs to large manufacturing plants, our round blades provide the reliable cutting solution needed for continuous operation.

Premium Material & Construction

Our round cutting blades are manufactured from a selection of premium materials tailored to specific cutting applications. We offer Tungsten Carbide (YG12) for exceptional wear resistance and long life on abrasive materials, SKD-51 and D2 tool steel for a balance of toughness and edge retention, and high-speed steels like W6Mo5Cr4V2 for high-temperature applications. Each blade is precision-ground to achieve exacting tolerances on outer diameter (OD: 160-610mm), inner diameter (ID: standard 25.4-75mm), and thickness (0.8-1.5mm). The cutting edge, typically set at a 45° angle (adjustable), is finished to a burr-free standard, ensuring clean cuts and minimal material drag.

Key Features & Benefits

Designed for longevity and reliability, these round blades deliver significant operational advantages. The primary benefit is burr-free cutting performance, which produces clean edges on finished products, reducing secondary finishing work. Their wide applicability across different materials makes them a versatile inventory item. The availability of both single-edge and double-edge designs allows for optimization based on cutting direction and machine setup. Precision manufacturing ensures consistent dimensions and balance, leading to smooth operation at high speeds, reduced vibration, and extended bearing life in the host machine. This results in higher quality output and reduced maintenance costs.

Application Industries & Materials

These versatile round blades are perfect for slicing a diverse range of non-metallic and thin metallic materials. They are highly effective in processing paper, plastic films, foam, rubber sheets, aluminum foil, graphite, and various composite materials. Key industries that utilize these blades include packaging and converting, printing, label manufacturing, textile processing, gasket production, and electronics manufacturing. They are commonly found in slitting machines, rewinders, die-cutters, and other precision industrial cutting equipment within manufacturing plants, machinery repair shops, and retail operations that require precise, consistent cutting.

Customization & Quality Assurance

We specialize in providing fully customized round blade solutions (OEM available). We can tailor all dimensions—outer diameter, inner diameter (bore size), thickness, and knife edge angle—to your exact machine specifications and material requirements. Our commitment to quality is demonstrated through video outgoing-inspection, allowing you to verify the product before shipment. We support our products with a 6-month warranty and provide comprehensive after-sales support, including video technical support and online assistance. While a machinery test report is not standard for this product line, our rigorous in-process controls ensure each blade meets precise performance criteria before shipment.
