  For general metalworking and medium production loads, the hydraulic WC67K-40T is a solid choice due to its durability and performance consistency.

• Material Thickness and Bending Radius

  The machine’s capacity must match the thickness and type of material you plan to bend. The WC67K-40T has a maximum bending force of 40 tons and is designed for materials like mild steel up to approximately 4–6 mm thick (depending on width and bend length).

  It excels at producing wide-radius bends and straight-line folding, making it suitable for:

  • Sheet metal enclosures
  • Ductwork and HVAC components
  • Brackets and structural supports

  This model is not recommended for tight-radius or complex multi-angle bends on thick materials, which require higher tonnage or specialized tooling.

• Dies and Tooling Selection

  Correct die selection is critical for achieving accurate bends and avoiding material damage. The term “dyes” in the original text is a typo—correctly referred to as dies. Common die types include:

  • V-Dies: Most common; used for standard air bending and suitable for thick or hard materials. The V-opening should be 6–8 times the material thickness for optimal results.
  • U-Dies: Used for forming wide-radius U-channels or pans, ideal for ducting and trays.
  • W-Dies: Less common; typically used for specialized, complex profiles requiring multiple forming stages.

  The WC67K-40T supports standard tooling setups and is compatible with modular tool systems, allowing quick changeovers and flexibility across job types.

• Workpiece Size and Bed Length

  The second number in WC67K-40T/2500 refers to the bed length: 2500 mm (2.5 meters). This determines the maximum width of sheet metal you can bend uniformly.

  When selecting a press brake, ensure:

  • The bed length exceeds your typical workpiece width to allow proper support and alignment.
  • The throat depth accommodates the depth of your parts.
  • The machine fits within your workshop layout, including space for loading/unloading.

  A 2500 mm bed is ideal for medium-sized fabrication shops handling panels, cabinets, and frames.

• Bending Accuracy and CNC Control

  Modern CNC press brakes like the WC67K-40T offer high precision through digital controls and backgauges. Key features to look for include:

  • Backgauge accuracy: ±0.05 mm or better ensures repeatable bend positioning.
  • CNC system: Look for user-friendly interfaces (e.g., Delem, Easson, or Cybelec) with programmable sequences and angle correction.
  • Angle measurement: Some models include laser or optical systems for real-time feedback.

  Higher-end models minimize human error and reduce setup time, especially for batch production.

• Load Capacity and Tonnage Requirements

  The 40-ton capacity of the WC67K-40T makes it suitable for general-purpose bending. However, required tonnage depends on:

  • Material thickness and tensile strength
  • Bend length (longer bends require more force)
  • V-die width and bending method (air bending vs. coining)

  As a rule of thumb, you need about 5 tons per meter for 3 mm mild steel. So for a full 2500 mm sheet, 40 tons is sufficient but near its limit. For heavier tasks, consider 60T or 80T models.

Pro Tip: Always perform a test bend with scrap material before starting production. This helps verify tonnage settings, die alignment, and CNC programming accuracy, reducing waste and rework.

Additional Considerations for Buyers

• After-Sales Support: Choose suppliers offering technical support, training, and spare parts availability—especially important for CNC systems.
