8MM Metal Plate Shearing Machine For Sale

SC 8mm metal plate shearing machine is a hydraulically driven guillotine shear suitable for cutting metal sheets up to 8mm thick. Common models include the QC11Y-8×3200 or QC11K-8×3200. This machine utilizes hydraulically driven upper and lower blades for shearing, specifically designed for shearing metal sheets up to 8mm thick.

It is suitable for shearing steel, stainless steel, aluminum, and other materials. It is widely used in industries such as sheet metal processing, machinery manufacturing, steel structure construction, electrical equipment, and automotive parts.

4. Analysis of Cutting Capacity of 8x3200mm Shearing Machine

The “8x3200mm” designation for the 8x3200mm hydraulic guillotine shear indicates a maximum shearing thickness of 8mm and a maximum shearing length of 3200mm.

The following is a detailed analysis of its shearing capacity:

1) Explanation of Basic Equipment Parameters

Shearing Thickness (8mm): This refers to the maximum thickness this shear can cut using standard materials (e.g., Q235 carbon steel, tensile strength ≤ 450MPa).
Shearing Length (3200mm): This indicates the maximum length of plate that this shear can cut in one go, meaning the maximum shearing width is 3.2 meters.

2) Detailed Analysis of Shear Capacity

Standard Shear Material: Q235 carbon steel (tensile strength approximately ≤ 450 MPa)
Maximum Shear Thickness: 8mm
Maximum Shear Length: 3200mm
Adjustable Blade Gap: Typically ranges from 0.04 x plate thickness to 0.1 x plate thickness, suitable for various plate thicknesses
Shear Angle: Approximately 0.5° to 2.0°. A larger angle reduces shear force but increases plate deformation.
Shear Rates per Minute: Typically 10-20 cuts/min, depending on machine model and hydraulic cylinder speed.

3) Reference Table for Shear Capacity of Different Materials

Material Type	Tensile Strength	Maximum Thickness (Estimated)
Q235 carbon steel	≤ 450MPa	8mm (rated)
Stainless steel (such as 304)	~600MPa	Approximately 5-6mm
Aluminum plate	~200MPa	Up to 10-12mm
Copper plate	~300MPa	Up to 8-10mm

Note: When shearing high-strength materials, the thickness should be appropriately reduced to ensure that the shearing machine is not overloaded.

4) Key Factors Affecting Shearing Capacity

Material Strength: The harder and stronger the material, the smaller the thickness that can be cut.
Blade Gap Adjustment: A reasonable gap ensures a clean cut and reduces tool wear.
Cutting Angle Setting: Increasing the cutting angle appropriately reduces shear resistance, but will slightly increase shear deformation.
Equipment Hydraulic System Pressure: This directly determines whether the shearing force is sufficient.
Blade Material and Sharpness: High-quality blades can cut thicker and harder materials.

5) Application Examples

This equipment is suitable for the following applications:

Cutting Q235 steel plates within 8mm for sheet metal processing and machinery manufacturing.
Cutting stainless steel plates ≤ 5mm for kitchen equipment and elevator manufacturing.
Cutting aluminum and copper plates within 10mm for decoration, electronics, and other industries.

5. 8mm Metal Plate Shear Selection

1) Selection Factors for Shearing 8mm Sheets

Shearing Thickness: ≥ 8mm (leaving an allowance for safety is recommended; a model with a rated shearing thickness of 9-10mm is recommended).
Shearing Length: Select based on the actual sheet width; common lengths include 2500mm, 3200mm, and 4000mm.
Shearing Material: For stainless steel or high-strength steel, a higher-tonnage model is recommended.
Drive Type: Hydraulic gate type is more suitable for medium and thick plates (e.g., 8mm).
Control Type: Standard hydraulic or CNC plate shearing machines (such as the E21 and DAC360) are available.
Blade Material: Cr12MoV or higher grade blades are recommended for excellent wear and crack resistance.
Blade Gap Adjustment: Automatic or manual adjustment to accommodate different thicknesses and material types.

2) Recommended Shearing Machine Specifications (Suitable for Shearing 8mm Sheets)

Recommended Model Specifications	Specifications
QC11Y-8×3200	Conventional Hydraulic Guillotine Shears: Shearing Capacity 8mm, Length 3200mm
QC11Y-8×4000	Capable of shearing up to 4 meters in length, suitable for large sheet metal fabrication plants
QC11K-8×3200 (CNC)	Equipped with E21 or E200 systems, with automatic back gauge adjustment

3) Special Recommendations

If you need to shear stainless steel (such as 304), we recommend a model with a 10 x 3200 mm or larger diameter to ensure adequate strength margin.
For high precision or mass production, we recommend a CNC shear with a CNC backgauge system.
For high efficiency and automation, you can add an automatic feed/discharge system or use it with a loading/unloading gantry.

If you have specific processing requirements (such as the number of sheets cut per day, material type, and whether automation is required), we can further recommend the appropriate machine model, control system, and configuration.
