Product Description

220 M/Min Coil Slitting Machine (Stainless Steel / Aluminum Coil Slitting Production Line)

-----------------------------------------------------CSKR MACHINE — Global Service, One-Stop Metal Building Solution Provider!----------------------------------------------

The 220 M/Min Coil Slitting Machine (Stainless Steel / Aluminum Coil Slitting Production Line) is a high-speed, fully automatic slitting solution designed for precision cutting of various metal coils—stainless steel, galvanized steel, aluminum, cold-rolled, hot-rolled, and more. With a maximum line speed of 220 m/min, it delivers exceptional throughput while maintaining tight slitting tolerances and minimal burr formation. Its modular design integrates decoiling, leveling, slitting, tension control, and recoiling into a seamless workflow, enabling single-operator efficiency and reduced labor costs. Major advantages include servo-controlled feeding for precise slit widths, heavy-duty precision disc-type knife seats for clean, burr-free edges, and robust recoilers that accommodate coils up to 25 tons. Typical applications span transformer and motor strip production, tube/pipe welding mill feedstock, ceiling drywall strips, and other downstream roll-forming industries.

Preface

Summary & Call to Action

Coil slitting is a foundational process in sheet-metal manufacturing, converting wide master coils into narrow strips for subsequent forming or fabrication. The 220 M/Min Coil Slitting Machine from leading manufacturers such as Kingreal, Kinbenz, and Hai Roll Fone exemplifies modern slitting-line engineering by combining high-speed capability with uncompromising accuracy. Designed to process materials ranging from 0.2 mm thin foils to 3 mm plate thicknesses, it supports coil widths up to 1000 mm (depending on model) and coil weights up to 25 tons   . Whether slitting stainless steel for corrosion-resistant applications or aluminum strips for lightweight components, this line meets diverse production demands with stable tension control and automated material handling   .

The 220 M/Min Coil Slitting Machine is engineered for manufacturers seeking maximum throughput without sacrificing slit precision or strip quality. By integrating high-speed disc-type slitting heads, advanced PLC-based tension control, and robust decoiling/recoiling modules, this line guarantees burr-free edges, tight tolerances, and minimal downtime. Its material flexibility—from stainless steel and galvanized coils to thin aluminum and copper strips—makes it ideal for transformer cores, motor laminations, ceiling grid strips, and a variety of downstream roll-forming sectors. Designed for single-operator simplicity yet expandable through optional modules, it offers a low total cost of ownership and future-proof performance.

Key Advantages

 1. Ultra-High Line Speed (220 m/min)
 • Achieves up to 220 m/min slitting speed on lightweight materials (e.g., aluminum, GI) with a 0.2–3.0 mm thickness range, drastically reducing cycle times for large orders   .
 • Optional upgrade kits enable stable high-speed operation on heavier gauges (up to 160 SPM slitting cycles on 0.3–2 mm strips) by reinforcing drive systems and optimizing coil buffering   .
 2. Precision Disc-Type Knife Seats
 • Utilizes CNC-machined, hardened-steel (40CrMo) disc knife holders with Cr12MoV slitting blades, quenched and tempered for long tool life and low burr   .
 • Slitting accuracy of ±0.10 mm or better (longitudinal tolerance ≤ 0.8 mm/m) is achieved through precision knife positioning and stable coil tension   .
 3. Robust Tension Control & Leveling
 • Integrated pinch-leveler stations (21 hardened rollers) before and after slitting remove coil set, ensuring flat, burr-free strips suitable for high-precision downstream processes (e.g., transformer windings, motor laminations)   .
 • Automatic tensioning units (eddy-current or pneumatic brakes) adaptively regulate strip tension throughout the slitting cycle to prevent oscillation or strip breakage   .

4. Heavy-Duty Decoiling & Recoiling
 • Decoiler capacity up to 25 tons with hydraulic expansion cores and motorized coil cars for safe, fast coil loading and threading   .
 • Recoiler with over-arm separating arms and pneumatic receptacles allows quick changeovers; recoiling shafts support ID 508 mm – 610 mm and OD up to 2000 mm for diverse coil ranges   .
 5. Modular & Flexible Design
 • Optional film-laminator modules apply protective film on slit strips for sensitive-surface metals (e.g., color-coated steel), expanding the machine's applicability to interior finishing panels and architectural decorative strips   .
 • Interchangeable slitting head modules support strip counts from 8 to 35 (depending on strip width and material gauge), enabling rapid reconfiguration for mixed production runs   .
 6. User-Friendly Automation & Safety
 • PLC-based control system (Panasonic or Siemens) with touchscreen HMI stores production recipes (material type, strip width, line speed), allowing one-click job changes   .
 • Full guarding with light curtains, emergency stops at each station, and safety interlocks on decoiler and recoiler shafts to prevent operator hazards during high-speed operation   .

Production Process

Production Process

 1. Decoiling & Coil Loading
 • Operator places coil (up to 25 T) on hydraulic decoiler; coil car positions and locks the coil; snubber rolls maintain tension during uncoiling   .
 • Coil opener peels the leading edge; loop-forming conveyors buffer material to allow synchronized slitting start   .
 2. First Leveling (Strip Flattening)
 • Material passes through a pinch-leveler (21 rollers, hardened & ground), eliminating coil memory and ensuring flatness before slitting knives engage   .
 3. Edge Guiding & Slitting
 • Side-guiding units align material; CNC-controlled servo feeders advance the coil to the slitting station. Precision disc knives (Cr12MoV) slice the coil into target strip widths (min. 30 mm)   .
 • Slitting speed up to 220 m/min, regulated by PLC to maintain consistent tension and knife engagement depth   .
 4. Buffering & Tensioning
 • Post-slitting, strips enter buffer loops to decouple slitting speed from recoiling speed; tension control units (eddy-current brakes) maintain strip tension for uniform recoiling   .
 5. Recoiling & Coil Unloading
 • Strips are rewound on recoiler shafts (ID 508–610 mm) with pneumatic separators; finished coils (max 2000 mm OD) are dispatched for downstream processing   .
 • Recoiler automatic carriage and over-arm separating arms facilitate quick coil change-over, maximizing uptime   .
