Product Specifications

Technical details and manufacturing context for Torch or Shear Cutting

Definition
Within an Industrial System, Torch or Shear Cutting is a critical component responsible for precisely cutting, trimming, or separating metal workpieces, plates, or structural sections. It enables the system to process raw materials into specific shapes and sizes required for downstream assembly or fabrication.
Working Principle
The component operates on one of two principles: 1) Torch Cutting: A high-temperature flame (often oxy-fuel or plasma) melts and blows away the metal along a controlled path. 2) Shear Cutting: A mechanical blade or die applies immense force to fracture and separate the material along a defined line, similar to scissors.
Common Materials
High-Speed Tool Steel, Tungsten Carbide, Copper Alloy
Technical Parameters
  • Maximum material thickness the component can effectively cut. (mm) Standard Spec
Components / BOM
  • Cutting Head / Torch Nozzle Part
    Directs the flame or plasma arc onto the workpiece to melt the metal.
    Material: Copper Alloy (for cooling), Ceramic
  • Shear Blade / Die Part
    Provides the sharp edge that applies force to fracture and separate the material.
    Material: High-Speed Tool Steel, Tungsten Carbide
  • Actuation Mechanism
    Provides the mechanical force or motion to drive the cutting action (e.g., hydraulic cylinder, ball screw).
    Material: Alloy Steel

Frequently Asked Questions

What are the main differences between torch and shear cutting methods?

Torch cutting uses thermal energy (typically plasma or oxy-fuel) to melt through metal, while shear cutting applies mechanical force with blades or dies to physically separate materials. Torch is better for thick or complex shapes; shear provides cleaner edges on thinner materials.

Which material is best for cutting blades in high-volume operations?

Tungsten carbide offers superior wear resistance for high-volume shear cutting, while high-speed tool steel provides better toughness for applications with potential impact or variable material thickness.

How do I maintain torch nozzles and shear blades for optimal performance?

Regularly inspect torch nozzles for wear and clogging, clean with appropriate solvents, and replace when orifice deformation occurs. Shear blades require periodic sharpening, proper alignment checks, and lubrication of moving parts to maintain cutting precision.

Can I contact factories directly on CNFX?
