How to choose a CNC shearing machine for the sheet metal industry?

A CNC shearing machine is a metal sheet shearing machine equipped with a CNC control system. It is the core equipment for sheet metal processing and can be regarded as an intelligent version of large-scale industrial shears. 

II. Working Principle 

Fix the lower knife and make the upper knife movable. The CNC system automatically sets the size, blade gap, and cutting stroke. Hydraulic power is provided. After the press foot fixes the sheet, the upper knife presses down to cut the steel plate, and the large sheet is cut into small sheets of the specified size. Only straight cutting is performed. 

III. Key Features 

• High precision: Numerical control servo positioning, with a dimensional accuracy of ±0.05mm. The dimensions are uniform in batches and the error is small. 

• Automation: The panel input size, program storage, automatic blanking, automatic cutting, with less manual operation. 

• Good cut: The section is smooth without burrs, and the sheet material does not deform easily. No need for a second grinding process. 

• Wide applicability: Can cut carbon steel, stainless steel, aluminum plates and copper plates, covering thin to medium-thick plates. 

• Safety and stability: Equipped with guardrails and safety interlocks, the hydraulic-driven operation is smooth and has low noise levels. 

IV. Main Applications 

Sheet metal cutting and sheet material processing are widely used in sheet metal factories, computer cases and cabinets, hardware, steel structures, kitchenware, automobiles, and wind power industries. They are used for large-scale cutting of standard-sized sheets. 

V. Common Categories (Mainstream in the Market) 

Pneumatic numerical control shearing machine: Strong rigidity, suitable for thick plates, large shearing force 

2. Swing-type CNC Shearing Machine: Compact design, smoother thin plate shearing, and excellent value for money. 

VI. Differences from Ordinary Shearing Machines 

For ordinary machines, the size adjustment and tool setting are all done manually, which leads to large errors and low efficiency;

While CNC machines allow for one-click programming, automatic positioning, high repeatability accuracy, and more material and labor savings for mass production.
