Spiro Curvecutter Delta 1500: Curvilinear Cutting Machine

Spiro Curvecutter Delta 1500: Curvilinear Cutting Machine


Spiro Curvecutter Delta 1500 is a high-precision automated machine specifically designed for cutting segments from sheet metal (e.g., angular segments, elbow segments, oval flat bends, domes) with very high repeatability and burr-free edges. The machine is suitable for series production lines, often integrated with other Spiro systems such as Rollformers, Stitchwelders, and Gorelockers. Key capabilities include: flat oval bends or circles with diameters ranging from to , segments with angle inclinations from to , and highly accurate cutting thanks to servo motor control. The machine is equipped with four roller-shears for cutting, which prevents burrs and edge hardening. Example performance: For an elbow with a diameter, consisting of segments, the machine can complete the cutting in a single pass in seconds.

Features and Advantages  
  • Vast Diameter Range: Capable of processing circular or oval blanks from a minimum diameter of up to a maximum of .

  • High Precision and Edge Cleanliness: The use of four roller-shears guarantees a burr-free edge without hardening of the material edge.

  • High Repeatability: Servo motor control allows for accurate and stable reproduction of defined cutting parameters (angle, diameter).

  • Productivity: Capable of producing up to segments per hour (for segments).

  • Operational Efficiency: Simple parameter input via the control panel, program selection, and quick changeover between different diameters and angles.

  • Minimization of Waste and Operating Time: One pass per segment (e.g., 4 segments per elbow) without unnecessary operations, reducing manual labor and downtime.

Standard Equipment  
  • High-Precision Servo Motors: In the drive system, responsible for the movement and positioning of the cut and the roller-shears.

  • Four Roller-Shears: For clean, burr-free cutting.

  • Control Panel: With program selection and the ability to set the diameter () and angle ().

  • Standard Materials Handled: Galvanized steel, aluminum, and stainless steel within the appropriate thickness range (see Technical Specifications).

  • Full Repeatability Validation: Consistent production of segments with identical parameters.

Options / Possible Additions  
  • Special Blades / Blade Coatings: For harder materials or materials with protective coatings to avoid surface damage.

  • Automatic Cut Angle Adjustment Means: (If not included in standard) — for faster transitions between different cutting angles.

  • Modules for Non-Standard Shapes / Segments: To process non-circular or non-oval parts with special curves.

  • Cut Line Illumination System: Or other visual aids for precise positioning.

  • Additional Safety Devices: If required by local market standards: guarding, light curtains or photo detectors, emergency stops.

  • Service Options: (Quick blade change, spare parts, possible condition monitoring program).
