Complete Metal Fabrication Workshop Equipment: Laser, Press Brake and Grinding
Engineering guide to setting up an integrated sheet metal fabrication facility: matching fiber laser cutters, CNC press brakes, surface grinders, and welding cells.
The Direct Engineering Answer
An integrated sheet metal fabrication workshop relies on a synchronized three-stage production line: cutting (a high-speed fiber laser cutting machine with dual exchange tables), forming (a multi-axis CNC hydraulic press brake with automated crowning compensation), and surface finishing/preparation (a precision surface grinding machine and deburring cell). Sourcing this complete machinery package from a single Turkish manufacturer like IXORTA in Konya guarantees unified electrical controls, synchronized tonnage-to-thickness capacities, and integrated factory commissioning under one master warranty.
Understanding the Buyer's Situation
Fabricators purchasing a laser from one vendor and a press brake from another often discover that CAD bend allowances don’t match laser hole offsets, or that press brake throat depth cannot accommodate folded panels cut on the laser table. Single-source Turkish manufacturing ensures flawless mechanical flow.

A complete industrial metal fabrication cell includes: 1. CNC Fiber Laser (IXORTA IX-FL-3015H): 3000 × 1500 mm cutting bed, 3kW to 6kW power, dual shuttle exchange tables, and CypCut CNC control. Cuts raw sheet metal into finished 2D blanks with pre-pierced bolt holes and bend relief notches. 2. CNC Hydraulic Press Brake (IXORTA IX-PB-160-3200): 160-ton bending force, 3200mm bed length, Delem DA-53T or DA-58T graphical CNC control, 4-axis backgauge (X, R, Z1, Z2), and motorized hydraulic crowning table to ensure uniform bend angles along long 3-meter sheets. 3. Precision Surface Grinder (IXORTA IX-SG-4080): 400 × 800 mm magnetic chuck table for precision grinding of stamping dies, press brake tooling, machine guide shims, and flat steel parts to ±0.003mm flatness.
Synchronizing Laser Kerf with Press Brake Bend Deductions
When designing sheet metal parts in 3D CAD (SolidWorks, Inventor): - The laser cuts flat patterns based on the sheet neutral axis (K-factor). - High-precision press brakes with hydraulic crowning eliminate the canoe effect (where the center of a 3-meter sheet bends under-angle compared to the ends). - Having matched machines ensures the fabricator achieves ±0.2mm overall assembly tolerances on folded electrical cabinets and machine frames.

Press Brake Tonnage Calculation: Bending 3.0mm Mild Steel (3 Meters)
Engineering Assumptions: Material: Mild Steel (Tensile strength: 450 N/mm²); Sheet thickness (t): 3.0mm; Length (L): 3000mm; V-die opening: 8 × t = 24mm.
- Standard V-die bending formula: Bending Force P = (1.42 × Tensile Strength × L × t²) ÷ (1000 × V-Die).
- P = (1.42 × 450 × 3000 × 3.0²) ÷ (1000 × 24) = 17,253,000 ÷ 24,000 = 718.8 kN.
- Convert kN to Metric Tons: 718.8 ÷ 9.81 = 73.3 Metric Tons.
- Safety Factor (1.3× for material thickness variation and tooling friction): 73.3 × 1.3 = 95.3 Tons required.
- Conclusion: An IXORTA IX-PB-160-3200 (160-ton capacity) operates comfortably at ~60% hydraulic pressure for this 3-meter bend, preserving hydraulic valve and seal lifespan.
⚠️ Critical Buyer Mistakes to Avoid
- Buying an un-crowned press brake for 3-meter bending, resulting in loose, uneven bends in the sheet center.
- Installing fiber lasers next to heavy mechanical stamping presses without foundation vibration isolation trenches.
- Neglecting high-pressure air filtration, allowing compressor oil mist to deposit on laser optics.
Frequently Asked Questions
What is the purpose of mechanical crowning on a CNC press brake?
When bending thick or long sheets, the press brake upper ram and lower bed deflect slightly under high hydraulic tonnage. Mechanical crowning automatically introduces a compensating convex curve into the lower bed, ensuring identical bend angles across the entire length of the sheet.
What software connects the fiber laser and press brake?
Standard 2D/3D nesting software (e.g., CypCut, Radan, or Lantek) processes 3D CAD models, generating flat laser DXF cut files with correct K-factor bend deductions while feeding bend sequences directly to the Delem press brake controller.
