1. General Description

The Dener DMMH 3106 NC guillotine shear is a used machine designed for cutting metal sheets with high precision and working capacity. This semi-automatic machine is particularly suitable for operations that require high cutting capacity and good working speed. Thanks to its robustness and advanced technical specifications, it is ideal for industrial environments where tight tolerances and high productivity are required.

2. Main Components

• Structure: Built in sturdy steel to ensure stability and durability over time.
• Cutting Blade: Upper blade and lower blade designed to make precise and clean cuts. The cutting angle of 1.42° allows a reduction in the deformation effect of the material.
• Sheet Metal Pushing Pistons: 14 pistons that help keep the material still and well positioned during cutting.
• Main Motor: 15 kW motor that drives the cutting mechanism and allows a high working speed.
• Rear Gauge Motor: 0.75 kW motor for precise adjustment of cutting length.
• NC Control System: Numerical control system for automated and precise management of cutting operations.

3. Technical Characteristics

• Cutting Length: 3100 mm, suitable for cutting medium and large sized sheets.
• Cutting capacity: 6 mm, allows you to cut materials up to 6 mm thick.
• Cutting Angle: 1.42°, helps to obtain precise cuts and reduce material deformation.
• Throat Depth: 45mm, which determines the maximum size of the piece that can be cut.
• Oil tank capacity: 180 litres, to ensure continuous operation and adequate lubrication.
• Sound Intensity: 60 dBA with load and 65 dBA without load, which indicates a relatively low noise level during operation.
• Maximum Pressure: 240 bar, the maximum operating pressure of the hydraulic system.

4. Formulas and Parameters of Optimal Use

• Cutting Speed ​​(v): The cutting speed depends on the material and thickness. The formula to calculate the theoretical forward speed is:
  v=n×p60v = \frac{n \times p}{60}
  $v$ $=$ 60 n × p ​Where

  • nn $n$ = Number of strokes per minute
  • pp $p$ = Material pitch in mm

• Cutting Pressure (P): The pressure required for cutting can be calculated using:
  P=FAP = \frac{F}{A}
  $P$ $=$ A F ​Where

  • FF $F$ = Cutting force in Newton
  • AA $A$ = Blade area in mm²

• Cutting Capacity: The cutting capacity of the machine must be chosen based on the thickness and hardness of the material. Use the 6mm capacity for typical materials and adjust the machine to material specifications.

5. Workable Materials

The Dener DMMH 3106 NC shear is designed to process a wide range of materials, including:

• Carbon steels
• Alloy steels
• Stainless steels
• Light alloys

The machine can be used for sheet metal up to 6 mm thick, depending on the material specifications.

6. Maintenance

• Lubrication: Check and maintain the hydraulic lubrication system in good condition. Check the oil level and replace it according to the manufacturer's recommendations.
• Blade Inspection: Regularly check the condition of the blades and sharpen or replace them if necessary.
• Cleaning: Keep the machine clean to avoid the accumulation of chips and dust which could compromise its operation.
• Hydraulic System Inspection: Inspect hydraulic system components for leaks or signs of wear.

7. Verification of used cars

• Wear Check: Check the condition of the blades, sheet metal pusher pistons and hydraulic components. Look for signs of wear or damage.
• Operational Tests: Test the machine to ensure that all functions are operational and that the cut is precise and uniform.
• Condition of Components: Check the lubrication system and hydraulic system for signs of malfunction or wear.
• Documentation: Request and verify documentation on previous maintenance and repairs carried out.

8. Sectors of Use

• Metalworking Industry: For cutting sheet metal and metals in workshops and processing plants.
• Construction Sector: For the preparation of metallic materials for structures and buildings.
• Automotive Industry: For the production of components and metal parts.

9. Why Buy Used

• Lower Cost: Purchasing a used shear such as the Dener DMMH 3106 NC is generally cheaper than purchasing a new one, reducing initial investment costs.
• Reliability: Machines like this, if well maintained and serviced, can offer reliable performance for many years.
• Historical Value: Quality shears such as the Dener DMMH 3106 NC have proven their ability to provide excellent results even after years of use.
