SHENCHONG 12mm hydraulic guillotine shearing machine is a very common type of medium-thick plate shearing equipment in the metal sheet processing industry. It is mainly used for straight-line shearing of metal sheets such as carbon steel, stainless steel, aluminum plates, and galvanized plates.

Typical models include QC11K-12×2500, QC11K-12×3200, QC11K-12×4000, and QC11K-12×6000, where "12" usually represents the maximum rated shearing thickness, and "3200" represents the maximum shearing width.

Taking the common 12×3200 specification as an example, the specific configuration will vary between different manufacturers. Publicly available parameters show a shearing angle of approximately 0.5° to 2.5°, a back gauge range of approximately 600 to 1000 mm, and a main motor of approximately 18.5 kW.

1. Typical 12X3200 Hydraulic Guillotine Shearing Machine Parameters

Taking a common 12X3200mm hydraulic guillotine shearing machine as an example, the following configuration can be referenced:

The parameters are not entirely consistent between different manufacturers.

2. Core Advantages

1) Strong Shearing Capacity

The 12mm class equipment belongs to medium-thick plate shearing equipment.

For ordinary carbon steel plates, it can cover a wide range of fields, including:

- Steel structure processing

- Engineering machinery

- Sheet metal manufacturing

- Machinery manufacturing

- Electrical cabinets

- Ventilation equipment

- Agricultural machinery

- Automotive manufacturing

- Shipbuilding equipment

- Construction machinery

2) High Shearing Efficiency

Compared to laser cutting, shearing machines typically have a significant efficiency advantage for large-volume, simple straight-line cutting.

For example:

A standard steel plate → Multiple straight-line cuts

Shearing machines are generally very suitable.

Because they eliminate the need for:

- Laser perforation

- Laser scanning

- Complex path planning

- Thermal cutting

Only the following steps are required:

Positioning → Pressing → Shearing → Return.

3) Minimal Heat Affected Zone

Shearing machines are mechanical shearing machines.

Unlike laser cutting, they do not produce a significant heat-affected zone, making them particularly suitable for:

- Heat-affected materials.

- Materials with high surface finish requirements.

- Sheets that will subsequently be bent for pre-cutting.

4) Relatively Controllable Cutting Costs

For large-volume straight-line shearing tasks, hydraulic shearing machines do not require laser generators, cutting gases, or other laser systems, making their overall operation more straightforward.

Especially for:

- Large-volume straight-line cutting of 12mm ordinary carbon steel plates

- Shearing machines often offer high economic efficiency.

3. What thickness of stainless steel can a 12mm shearing machine cut?

This is a frequently asked question during the procurement process.

The answer is:

It cannot be simply assumed that "a 12mm shearing machine = can cut all materials up to 12mm thick".

The rated shearing capacity of the equipment is usually based on the specific material strength conditions.

If the material has a higher tensile strength, such as certain stainless steels or high-strength steels, its actual shearable thickness needs to be reduced.

For example:

Therefore, if the customer primarily processes 304 stainless steel, the equipment capacity cannot be determined solely based on "12mm".

The following should be provided to the manufacturer for confirmation: material grade + thickness + width + tensile strength + processing frequency.

4. How to choose between 12mmX3200 and 12mmX2500?

This is a typical procurement question.

12×2500mm hydraulic guillotine shear

Suitable for:

- Small to medium-sized sheet metal factories

- Electrical cabinets

- Mechanical parts

- Ventilation equipment

- Ordinary steel plate processing

Advantages:

- Smaller equipment size

- Less floor space

- Relatively low investment

- Easy daily operation

12×3200mm hydraulic guillotine shear

Suitable for:

- Wider steel plates

- Steel structures

- Engineering machinery

- Larger sheet metal

- Large equipment manufacturing

If the company frequently processes:

Approximately 3000mm plates

Then 12×3200 is usually more suitable than 12×2500.

5. What automation configurations can be added to a 12mm hydraulic guillotine shearing machine?

For modern sheet metal factories, the following can be further configured:

1) Front feeding system

Automatically feeds the sheet metal into the shearing area.

Suitable for:

Mass production

Fixed-size production

Reduced manual handling

2) Pneumatic support

Supports the sheet metal during the shearing process. This is especially useful for large-sized sheets.

3) Front Support Device

Helps operators position and support large sheets.

4) Rear Support System

Automatically receives sheets after shearing.

5) Automatic Feeding

Can be combined with: Sheet storage system + loading system + shearing machine.

Further develops an automated material handling production line.

7. 12mm Hydraulic Guillotine Shearing Machine Purchase Recommendations

For general sheet metal companies, consider:

12×2500mm

For medium to large sheet metal and steel structure companies, prioritize:

12×3200mm

If frequently processing large steel plates:

12×4000mm

If dealing with a large number of extra-long plates:

12×6000mm

The control method should be selected according to the production mode:

SC 12mm hydraulic guillotine shear is essentially a specialized piece of equipment for efficient, straight-line cutting of medium-thick metal plates.

Its greatest value lies not merely in its ability to cut 12mm steel plates, but in the complete plate shearing system it forms through: a high-rigidity frame, hydraulic drive, precision blades, optimized blade clearance, adjustable shearing angle, CNC back gauge, and a clamping system.

For companies primarily processing 6-12mm carbon steel, stainless steel, and other metal plates, a 12mm hydraulic guillotine shear is typically a very practical medium-thick plate cutting machine.

The 12X3200mm configuration is a representative example: publicly available product parameters include configurations with approximately 18.5kW main motors, 3200mm shearing widths, and approximately 9 cuts/min, as well as options with different shearing angles, back gauge ranges, and overall machine weights. Therefore, actual procurement must adhere to the specific manufacturer's complete technical agreement.

From the perspective of modern sheet metal factories, further combining a 12mm hydraulic guillotine shearing machine with a CNC back gauge, front support/pneumatic support, automatic feeding, and intelligent sheet metal storage can gradually upgrade from single-machine shearing to an automated sheet metal cutting unit. This is particularly valuable for reducing manual handling, improving dimensional consistency, and enhancing overall production efficiency.
