SC 6mm sheet metal shearing machine is a cuting device used for cutting carbon steel, stainless steel, and other metal sheets with a thickness of ≤6mm. The equipment is hydraulically driven and features stable structure, high shearing precision, simple operation, and high safety and reliability. It is widely used in sheet metal processing, machinery manufacturing, ventilation ducts, automotive parts, and metal products industries.

2. 6MM Sheet Metal Shearing Machine Structure Composition
Main Components:
- Frame (welded and annealed)
- Upper and Lower Blade Posts (6mm grade blades)
- Hydraulic System (integrated valve group or electro-hydraulic servo)
- Backgauge System (CNC optional)
- Pressure Cylinder (multi-point pressure to prevent material movement)
- Foot Switch/Emergency Stop Switch
- Spherical Support Plate and Front/Rear Material Supports
1) Frame Section
Integral welded structure, tempered and aged to ensure no deformation during long-term use.
Left and right columns, cylinder seats, and worktable are machined as a whole for high precision.
2) Upper Blade Post
Used welded steel plate structure for high strength.
The guillotine structure uses linear sliding guides to keep the blades parallel during shearing.
The swing-type structure features arc-shaped motion, simple structure, and convenient maintenance.
3) Blade System
Both upper and lower blades are made of alloy tool steel (9CrSi / Cr12MoV).
The upper blade is four-edged and replaceable, and the lower blade is two-edged and replaceable, with a long service life.
The blade gap can be adjusted manually or electrically according to the sheet thickness.
4) Material Holding System
Multiple hydraulic pressure cylinders are arranged for reliable material holding, preventing sheet movement during shearing.
The pressure foot uses a rubber pad to prevent scratching the material surface.
5) Hydraulic System
Integrated hydraulic valve blocks are used, reducing piping and improving stability.
Key hydraulic components are from well-known brands (such as Rexroth and Heidegger).
Overload protection and a filtration system are included.
6) Back gauge System
Electrically adjustable or controlled by a CNC system (E21S/DAC 360/ELGO P40).
Precision ball screw drive ensures high positioning accuracy.
A servo motor can be added for high-speed and high-precision positioning.
7) Electrical Control System
The control system complies with CE safety standards.
Continuous/single/inching shearing modes are available.
Equipped with a foot switch and emergency stop button.
8) Material Support System
The front material support platform uses a ball support or brush structure to reduce scratches.
A rear receiving rack or rear feeding system is optional.
Working Principle Of Plate Shearing Machine:
- The blade gap and shearing angle are adjusted according to the sheet thickness.
- The sheet is placed on the front support platform, and its size is adjusted using the positioning stop.
- The pressure cylinder is activated to clamp the sheet.
- The upper blade holder performs the shearing action under hydraulic drive.
- After shearing, the upper blade holder resets, and the pressure cylinder is released.
- The back gauge automatically resets or continues the next shearing operation according to the set values.
The entire process is completed by the coordinated operation of the hydraulic and electrical control systems, resulting in stable operation and high efficiency.

3. 6mm Metal Plate Shearing Machine Operating Instructions
Pre-start Checks:
- Check hydraulic oil level.
- Check blades for tightness.
- Check emergency stop button for reset.
- Check back gauge position and CNC parameters for accuracy.
Shearing Operation:
- Turn on power and start hydraulic pump.
- Adjust blade gap according to plate thickness.
- Input shearing dimensions (if CNC).
- Place plate on the support platform.
- Execute shearing action by foot pedal or button.
- Remove plate after shearing.
Shutdown Procedure:
- Stop shearing and turn off hydraulic pump.
- Disconnect main power.
- Clean up debris around the equipment.
4. Safety Precautions
- Do not cut two different sizes or materials of boards simultaneously.
- Do not put your hands under the pressure zone or the blade.
- A pressure device must be used when cutting.
- Large boards require at least two people to handle.
- Repairs must be performed by qualified technicians.
5. 6mm Plate Shearing Machine Selection Recommendations (Based on Material and Width)
To ensure the long-term stable operation of your sheet metal shearing machine in your actual working conditions, the following selection recommendations can be used to quickly determine the appropriate model:
- Select By Material Type
Materials | For 6mm thick board | Recommended Notes |
Carbon steel Q235/Q345 | Fully suitable | Rated parameters are based on Q235. Q345 can be cut, but the cutting thickness limit should be appropriately reduced. |
Stainless steel 304/201 | Thickness reduction of approximately 20-30% is required | For long-term cutting of stainless steel, it is recommended to choose a larger model (e.g., an 8mm model) to extend its lifespan. |
Aluminum plate/Aluminum alloy | Very easy | A standard 6mm model can be used without increasing power. |
The harder the material, the higher the shearing force required by the equipment. If your company mainly produces stainless steel, it is recommended to choose a machine model with a larger shearing thickness. If you are shearing 6mm 304 stainless steel for a long time, please choose an 8mm model for greater stability.
- Select by cutting width (very critical)
Different widths affect the strength of the cutter head, the rigidity of the worktable, and the load on the hydraulic system.
(1) Plate width ≤2500mm (2.5m)
Recommended model: 6×2500
- Best economical, lowest price
- Suitable for ductwork, small sheet metal factories, and engineering processing points
(2) Plate width ≤3200mm (3.2m)
Recommended model: 6×3200 (mainstream model)
- Most widely used in the industry, adaptable to common laser cutting plate sizes (1500×3000)
- Stronger stability
(3) Plate width ≥4000mm (4m)
Recommended model: 6×4000 or customized 6×6000
- Suitable for large ductwork factories and large-format metal processing factories
- Larger equipment tonnage and frame weight
- It is recommended to prioritize models with a width of ≥3200mm, which are more versatile and can accommodate more orders.
