A metal coil cut to length machine, commonly shortened as CTL machine, is a specialized automated metal processing production line designed to convert rolled metal coil raw materials into flat, standardized metal sheets with fixed customizable lengths. Unlike metal slitting machines that
cut coils into narrow strips, CTL equipment performs transverse cross-cutting on continuous metal strips. It integrates unwinding, flattening, sizing,shearing and stacking into one continuous workflow, serving as core processing equipment in metal fabrication industries. This full-line equipment replaces traditional manual cutting and discrete mechanical cutting methods, realizing batch, high-precision and low-waste sheet production for ferrous and non-ferrous metal materials.

Today we introduce 2x1300mm metal coil cutting machine.  This is economic and simple cut to length machine, working speed up to 16m/min. 

The working flow as follows:

Hydraulic decoiler----feeding and leveling machine------cutting machine------transport table-----automatic stacker 

The main technical specifications of coil cut to length machine 

1. hydraulic decoiler 8 tons 

• Usage: make uncoiling initiative or recoiling
• Structure: single head
• Inner diameter:Φ508mm/Φ610mm
• The core spindle with 4 PCS supporting arm, make the coil is close to circle
• when expanding, ensure not scratch the coil paiting.
• Driven by frequency conversion motor and can be rewound.
• Pneumatic disc brake is installed at the end of the spindle, which can generate unwinding tension and brake.
• The pressing arm is installed above the spindle. The pressing arm rollers is coated with rubber. The electric rotation and hydraulic swing are used
• uncoiler driven motor power: 4kw
• Uncoiler frequency conversion motor power: 7.5kw
• Hydraulic station motor power:4kw
• Capacity: 8 tons

2. Feeding and leveing machine 

• Leveling rollers: up 5 rollers + down 6 rollers, total 11 leveling rollers
• Leveling rollers diameter: ф80mm
• Leveling rollers width: 1400mm
• Leveling rollers material: 40Cr, quenched, with hard chromed.
• Pinch rollers: 1 group, total 2 rollers
• upper and lower support rollers use oblique iron regulation, avoid leveling rollers deformation when forced.

 

3. Cutting machine 

• Cutting motion: From up to down, the main machine automatically stops and then cutting. 
• Material of blade: CR12MoV, cut from up to down, 4 sides to use
• Length measuring: Automatic length measuring
• Tolerance of length: +/-1mm
• Cutting width:1300mm max
• Cutting thickness: max 2mm

 

4. Transport table 

•  Conveyor belt: with high tensile fiber conveyor belt, anti-skid and wear-resistant.
• Power: With the speed of the production line, it is driven by 2.2Kw speed regulating motor with reducer.
• Mechanical structure: steel plate and square pipe welded assembly.
• Length: 4000mm
• Width: 1300mm
• Function overview: Transfer the cut sheet material to the receiving device. Because of the length of the shearing sheet is different, the speed of the conveying table can be adjusted according to the time shearing situation.

5. Automatic stacker 

• Width:1000-1300mm
• Length:1000-4000mm
• The cylinders push tidily and together automatically.
