High-Precision Knive Shaft

The high-precision knive shaft is the core load-bearing component of the circular shear unit in the slitting line. It is used for mounting circular shear blades. Through its high-rigidity and high-precision structural design, it ensures the stable positioning of the blades during the shearing process.

Applications
As the "blade carrier" of the circular shear, its core functions are: precisely fixing multiple sets of circular blades on the shaft body, cooperating with the synchronous rotation of the cutter shaft to complete the longitudinal slitting of wide-width coils; at the same time, bearing the impact force during shearing and maintaining the stability of the blade gap.

Features & Advantages

• Ultra-high precision: The axial end runout and flatness of the blade mounting reference surface are controlled within an extremely narrow range, ensuring stable and high precision in slitting width.
• High rigidity: Made of high-strength alloy material and subjected to professional heat treatment, it has excellent impact resistance and avoids shaft deformation during shearing.
• Quick-installation adaptability: Supports modular blade installation, with a convenient blade assembly and disassembly process, effectively improving tool change efficiency.
• Long service life: The surface is treated with a wear-resistant process, which significantly enhances wear resistance and enables long-term stable working conditions.
