Most burr problems are not simply caused by low blade hardness. Multiple factors work together to ruin finished strips. Incorrect blade clearance setting, unstable material structure and poor heat treatment of cutting tools all lead to inconsistent cutting results. Low-grade blades lose edge sharpness quickly under continuous high-speed operation. Once the cutting edge wears, operators need to stop production for disassembly, grinding or replacement, which cuts output and raises labor expense.
For carbon steel, galvanized steel and thin stainless steel coils, the tolerance requirement of strip edge is strict. Even tiny burrs may lead to scrap in the subsequent stamping or forming process. That is why more steel mills switch to stable, precisely machined flat steel longitudinal shear blades to maintain consistent slitting quality for long-run production. Xinzhe Tools runs full-process production from raw material forging, precision machining to vacuum heat treatment, to guarantee stable hardness and uniform internal structure of each blade.
Unlike general suppliers who only process semi-finished blanks, Xinzhe Tools controls every production stage in-house. The factory selects premium alloy tool steel and high-speed steel grades according to customers’ actual cutting materials. The precision grinding process keeps tight dimensional tolerance on outer diameter, thickness and bore size. Every finished blade goes through hardness inspection and surface flaw detection before packing.
Many overseas clients comment that blades from Xinzhe Tools show better wear resistance and less chipping when working on heavy gauge flat steel. Custom dimension service is available to match different slitter machine models. When customers provide coil thickness, slitting speed and target edge standard, our technical team can recommend proper material grade and blade clearance reference. This one-stop technical support separates Xinzhe Tools from ordinary traders. The flat steel longitudinal shear blades can operate steadily for long continuous slitting cycles and reduce unplanned maintenance.
High-quality blades still need proper installation and daily maintenance to maximize value. Operators should check blade clearance regularly and avoid overloading the slitter line beyond rated capacity. Rust prevention is essential for sea shipment and storage. Xinzhe Tools applies anti-rust coating and VCI wrapping for export orders, protecting blades from moisture damage during long ocean transport.
Before bulk order delivery, sample testing is supported for new customers. Factory test reports can be provided together with goods. Xinzhe Tools keeps standard specifications in stock for fast delivery, while custom machined items follow strict production schedules. By pairing correct operating parameters with qualified cutting tools, steel processors can lower tool consumption and improve finished strip yield.
