Product Overview
Our cnc shearing line is a fully automatic CNC-controlled cut-to-length production line independently developed and manufactured by Taian Lishen Machinery Technology Co., Ltd. Founded in 1996, our factory has rich experience in metal sheet processing equipment and steel drum production machinery. This automatic shearing line integrates uncoiling, leveling, precise sizing and hydraulic shearing into one complete production workflow.
This metal coil shearing line is specially engineered for cutting metal coils into flat, burr-free rectangular sheets with consistent flatness and ultra-high dimensional accuracy. It can process carbon steel, stainless steel, galvanized steel and aluminum sheets, widely used for steel drum manufacturing, solar water heater tank production, sheet metal stamping and general metal fabrication industries. All our CNC shearing machines are certified with ISO 9001 quality system and pass strict 24-hour continuous running tests before shipment, helping factories achieve unmanned and high-efficiency sheet cutting.
Working Principle
The whole cnc shearing line adopts Siemens PLC centralized control system, supporting automatic continuous circulation without frequent manual intervention. The complete working process is simple and systematic:
Step 1 Uncoiling: The hydraulic decoiler steadily loads raw metal coils and feeds raw materials to the leveling unit to avoid material deviation and coil jamming.
Step 2 Leveling: Multi-row solid leveling rollers eliminate internal stress and surface radian of coiled materials, ensuring finished sheets maintain excellent flatness for subsequent welding and stamping processes.
Step 3 CNC Precision Positioning: Workers input target cutting length and quantity on the touch screen. The servo feeding system accurately controls feeding distance to realize fixed-length cutting.
Step 4 Hydraulic Shearing: The high-hardness integral shear blade finishes fast vertical shearing. The hydraulic buffer design effectively reduces burrs and sheet deformation during cutting.
Step 5 Automatic Stacking: Qualified flat sheets are automatically sorted and stacked by the stacking platform, easy for workers to transport and store.

cnc shearing Line
A cnc shearing line, also known as an automatic Cut-to-length Line, is a high-efficiency integrated metal processing system widely used in modern sheet metal manufacturing. Engineered for uncoiling, leveling, positioning and shearing metal coils into standard flat sheets, this automated production line has become essential equipment for steel drum production, solar equipment fabrication and general metalworking industries. Manufactured by Taian Lishen Machinery Technology Co., Ltd., a professional machinery producer founded in 1996, the CNC shearing line adopts mature CNC and hydraulic technologies. It has obtained ISO 9001 certification and undergone strict performance tests, delivering stable, precise and durable performance that meets international production standards for factories worldwide.
The CNC shearing line operates under unified PLC control to realize fully automated continuous production. Raw metal coils are first uncoiled smoothly by a hydraulic decoiler, then processed by multi-roller leveling units to eliminate material radian and internal stress. After precise positioning via servo feeding systems, the materials are cut into required lengths by high-performance hydraulic shears. This equipment supports sheet thickness from 0.2 mm to 16 mm, sheet width ranging 200 mm to 2000 mm with customized width up to 3200 mm, and shearing length between 300 mm and 6000 mm. It maintains outstanding precision, with shearing accuracy within ±0.05 to ±0.5 mm and leveling accuracy below 0.5 mm per square meter. The running speed reaches 60 to 120 meters per minute, and it can carry coil rolls weighing 10 to 30 tons, fully adapting to large-scale industrial production demands.
Featuring remarkable technical strengths, the CNC shearing line stands out from traditional separate shearing machines. Its integrated structure combines multiple working procedures into one line, greatly simplifying production flow and cutting labor costs. The intelligent control panel allows operators to set and store various processing parameters for quick switching between different product specifications. Heat-treated shear blades and heavy-duty welded frames ensure long service life, while the centralized lubrication design lowers daily maintenance work. Suitable for carbon steel, stainless steel, galvanized sheets and aluminum sheets, this line works perfectly with bending machines, rolling equipment and welding units to form a complete metal processing workshop. It serves diverse sectors including metal packaging, new energy, hardware and automotive manufacturing.
