Precision at Scale: Leon Machinery 4.5×1600 Coil Slitting Machine Brings Industrial Cutting Power

Why the Leon Machinery 4.5×1600 Matters

You need a slitting line that handles up to 4.5 mm thickness, 1,550 mm width, line speeds to 120 m/min, and accuracy down to ±0.01 mm. That’s exactly where Leon Machinery’s model 4.5×1600 shines. It’s not just specs—it delivers tight tolerances, stable recoiling, and proven reliability in ISO‑9001 certified production.

Technical Dimensions & Performance

From coil entry to stripped-edge rewind, every component meets rigorous industrial demands.

• Material Range: 2.5–4.5 mm hot‑rolled mild steel (max thickness supported); min thickness up to 0.2mm with optional slower speed setup

• Width Flexibility: 800–1,550 mm working range; designed for entry coil diameters up to 1,600 mm and weight up to 25 tons

• Line Speed: 0–120 m/min, with steady operation across the thickness

• Precision Control: Horizontal and vertical beat held within ±0.01 mm; final slit-width tolerance ±0.20 mm

Core Machine Components – A Walkthrough

Each sub-system supports repeatable, safe operation and rapid changeovers.

Unloading & Decoiling Systems

Hydraulic coil-loading dolly transfers and positions coils smoothly. The umbrella-style double-head hydraulic decoiler allows left-right movement and centralization—ideal for large coils.

Infeed Mechanisms

Hydraulic press-guide, shovel head, opener, and pinching assemblies ensure stable material feeding and alignment before slitting.

Rough-Leveling Unit

A three-roll leveling cluster eliminates coil set and feed inconsistencies. It's built for robustness while staying inactive under lighter gauge.

Slitting Station

Upper and lower tooling shafts (220 mm diameter, alloy 40Cr) drive H13K blades at HRC55–58 hardness. Blade changing and positioning controlled hydraulically for fast changeover.

Scrap Rewind & Main Recoiler

Two-stage rewind: scrap goes to stripper unit; slit coils pass through 90 kW motors in the recoiler with hydraulic expansion grips. Rewind rates adjust based on thickness (up to 25 m/min).

Loop Loop Pit & Transition Tables

Looping pit (5.5 × 2.2 × 2.5 m) plus 3 m transition tables smooth strip control and reduce tension during operation.

Control & Safety Ecosystem

PLC-controlled central console with emergency stops, overload warnings, safety guards, and a hydraulic power unit delivering 25 L/min ensures precision control.

Real‑World Application Scenarios

Coil Processing Centers

With tight width tolerances and multi-thousand‑ton/year throughput, this model powers service centers needing strip-ready outputs. Platform width and thickness flexibility serve cold-rolled, galvanized, or stainless coils.

In‑House Fabrication for OEMs

Facilities needing to rewind slit coils for pipe mills or tubular fabrication rely on consistent slit widths and precise tension control. The Leon Machinery system offers clutch‑less speed control and precise indexing for downstream automation.

Automotive & Appliance Manufacturers

When demanding narrow strips or precision blanks for downstream forming or welding, this line delivers the accuracy and throughput industrial use demands.

Advantages That Matter

• Industrial Precision: Beat accuracy to ±0.01 mm and slit-width tolerance ±0.20 mm ensures minimal post-processing.

• High Throughput: Speeds up to 120 m/min with minimal downtime.

• Robust Capacity: Supports up to 25 ton coils with 1,600 mm OD.

• Modular Controls: Hydraulic tooling with PLC-based interface enables efficient operator workflows.

Ideal for These Environments

• Steel distributors needing narrow strips and multiple widths from the same coil

• Manufacturing lines producing cold‑rolled or HR coil blanks

• Facilities needing flexibility to handle gauges from 2.5 mm to 4.5 mm
