High-Speed Cr Coil Slitting Line Factory in China - Top Suppliers for Precision Slitting Solutions
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.
- ✅ 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.
- 🏭 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.
- 🔧 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, as well as various plated and coated coils. It is versatile enough to serve industries such as automotive, containers, household appliances, food packaging, and construction materials.
Q
What is the maximum coil thickness and width the slitting machine can handle?
Depending on the model, the slitting machine can handle coil thicknesses ranging from 0.2 mm up to 6 mm, and coil widths from 400 mm up to 1,600 mm. The 6×1500 model, for example, supports thicknesses of 1–6 mm and widths of 500–1,500 mm.
Q
What is the working principle of the slitting machine?
The slitting machine works by continuously roll-cutting the coil material through the synchronized rotation of upper and lower circular disc knife shafts. The material is fed through the knife shafts, which precisely divide it into multiple narrow strips of the required width along the length direction.
Q
What components make up a complete coil slitting production line?
A complete coil slitting line consists of a loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller, and coil recoiler. Loop bridges, pinch rollers, and deviation correctors are also equipped between each machine to ensure smooth and precise material flow throughout the entire process.
Q
How is the precision and durability of the knife shafts ensured?
The knife shafts and frames undergo a rigorous series of precision machining processes, including turning, high-frequency heat treatment, grinding, and chrome plating. These processes ensure exceptional rigidity, dimensional accuracy, and long-term durability of the equipment, even under continuous high-load production conditions.
Q
What is the maximum line speed and power consumption of the slitting line?
The line speed varies by model, ranging from 0–60 m/min for the heavy-duty 6×1500 model up to 90–120 m/min for the 3×1600 model. Total power consumption ranges from ≤90 KW for the smallest model (1.2×1250) up to ≤245 KW for the largest model (6×1500), making it adaptable to different production capacity requirements.
