Flying Shear Blade
The disc rotary shear blade used in the metallurgical strip steel slitting industry, also known as the strip cutting machine blade, rotary shear machine blade, rotary shear machine round blade, longitudinal slitting machine blade, disc blade, etc. It is mainly used for slitting items such as paper, film, gold and silver foil, copper foil, aluminum foil, and magnetic tape. It requires that the blade has small cutting resistance and great wear resistance. Due to the requirement for the accuracy of goods, the cutting edge sometimes needs to reach micron-level accuracy.
High-Precision Disc Rotary Shear Blades for Burr-Free Slitting
Achieving flawless edge quality in metal coil processing requires the extreme precision of disc rotary shear blades. TINVO manufactures premium circular slitting knives designed to handle various gauges of carbon steel, stainless steel, aluminum, and copper with unmatched accuracy, ensuring clean, burr-free edges for your high-speed slitting lines.
Superior Material Stability: We utilize elite tool steels such as D2 (SKD11), H13 (SKD61), and Tungsten Carbide. These materials are selected for their ability to maintain structural integrity and a razor-sharp edge under continuous rotational stress and thermal load.
Mirror-Finish Grinding: Every rotary shear blade is precision-ground to a mirror finish. This reduces friction and material buildup on the blade sides, preventing scratches on the metal strip and extending the time between regrinds.
Ultra-Tight Tolerances: To ensure perfect synchronization in your slitting line, our blades are machined to extreme tolerances for thickness (±0.002mm) and lateral runout. This precision eliminates strip-width variations and ensures stable shearing at high speeds.
Advanced Vacuum Hardening: Through a strictly controlled heat treatment process (typically HRC 58-62), we achieve a uniform microstructure that balances edge toughness with surface hardness, minimizing the risk of edge chipping during heavy-gauge shearing.
Tailored for Side Trimming & Slitting: Whether you are trimming the irregular edges of a hot-rolled coil or slitting thin-gauge electrical steel, we provide custom blade geometries and clearances optimized for your specific material type and thickness.

The incision of the blade of the slitting machine made by TINVO is smooth and flat, the cutting edge is resistant to wear and tear within 0.003, the thickness tolerance is ±0.001, and the finish can reach within 0.8. New materials such as W6Mo5Cr4V2Co(A1) and SLDDC53 have unique toughness and wear resistance, which are especially suitable for the precise slitting of 0.1-10mm stainless steel. The cutting edge of the blade of the slitting machine is sharp and resistant to wear, the incision is smooth and straight, there are many product specifications and a complete variety, and non-standard products can be processed and customized according to customer requirements.
The main materials used for the blade of the slitting machine are T10, 6CrW2Si, Cr12MoV, LD, H13, W18Cr4V and other high-quality tool steels and high-alloy die steels, which are widely used in trimming and stripping of thin, medium and thick plates, such as hot-rolled coil pipes, pickled plates, electroplated and colored steel plates, silicon steel plates, stainless steel, and sand steel sheets. The general materials include W18Cr4V, W6Mo5Cr4V (SKH), Cr12MoV (SKD1), 9CrSi, 65Mn, etc.
