High-Speed Cr Coil Slitting Line from China Factory - Top Suppliers for Thickness 0.25-20mm, Width 200-3000mm
Product Introduction
The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.
The following is a comprehensive introduction to the core features of the slitting and shearing machine:
Core Structure & Unit Composition
The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.
Wide Applicability & Material Compatibility
This series of production line is applicable to coils of various specifications. It is used for slitting the coil into required width for the use of punch line through the procedure of uncoiling, pre-leveling, cropping, slitting and recoiling. It has advantages such as proper layout, easy operation, highly automated and high production efficiency.
Supported Material Types
This line is adaptable to process cold-rolled and hot-rolled coils, silicon steel coils, stainless coils, colored coils, aluminum coils, and all sorts of plated and coated coils, and it widely applies to many industries like automobiles, containers, household appliances, food packing, construction materials, etc.
Line Composition & Integration
This line consists of loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller and coil recoiler, etc. Loop bridge, pinch and deviation corrector are equipped between each machine. This automatic coil processing line is an integration of mechanical, electrical, hydraulic and pneumatic technology.

Frequently Asked Questions (FAQ)
Q
What types of materials can the coil slitting line process?
The coil slitting line is designed to process a wide range of materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, and various plated or coated coils. It is suitable for industries such as automotive, containers, household appliances, food packaging, and construction.
Q
What is the maximum coil thickness this slitting machine can handle?
The maximum coil thickness depends on the model selected. For example, the 6×1500 model can handle coil thicknesses from 1mm up to 6mm, while the 1.2×1250 model is suited for thinner materials ranging from 0.2mm to 1.2mm. Please refer to the technical parameter table for detailed specifications per model.
Q
What is the maximum line speed of the slitting machine?
The line speed varies by model. The 1.2×1250 model operates at 80–120 m/min, the 3×1600 model at 90–120 m/min, while the 2×1250 and 6×1500 models support variable speeds up to 100 m/min and 60 m/min respectively, allowing flexible production adjustments based on material and application requirements.
Q
What main components make up the coil slitting production line?
The complete coil slitting line includes a loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller, and coil recoiler. Loop bridges, pinch rolls, and deviation correctors are installed between each unit to ensure smooth and accurate material flow throughout the entire production process.
Q
How is the precision and rigidity of the knife shaft maintained?
The knife shafts and frames are manufactured through a series of precision processes, including turning, high-frequency heat treatment, grinding, and chrome plating. These processes ensure exceptional rigidity, dimensional accuracy, and long service life, resulting in consistent and clean slitting cuts across all supported material types.
Q
Is the slitting line suitable for automated production environments?
Yes. The coil slitting line integrates mechanical, electrical, hydraulic, and pneumatic technologies into a fully automated system. It features a proper layout, easy operation controls, and high production efficiency, making it well-suited for modern automated manufacturing environments that require consistent output and minimal manual intervention.
