CNC Press Brakes
Hydraulic forming systems with CNC back gauge control deliver repeatable bend angles within ±0.5° across production runs, transforming flat sheet metal into precise structural components for fleet upfitting applications.
Controlled Force, Predictable Results
Press brake forming applies precisely controlled tonnage to bend flat sheet metal around a punch and die assembly. Our CNC-controlled back gauge positions material to within ±0.010" before each bend, while programmable hydraulic pressure compensates for material variations to maintain consistent bend angles across every piece in a production run.

Why Press Brake Forming for Fleet Components
Structural Integrity Through Grain Direction
Bending preserves the grain structure of the base material, unlike welded assemblies where heat-affected zones create weak points. A single-piece bent bracket maintains full material strength characteristics throughout its geometry.
No Minimum Order Quantities
Press brake tooling is adaptable - we use standard punch and die sets for most geometries. This eliminates the custom tooling costs that make stamping and roll forming prohibitively expensive for orders under 5,000 pieces. Run pilot quantities of 10-50 pieces at reasonable per-part costs.
Engineering Changes Cost Hours, Not Weeks
Modify a bend angle or flange length by updating the CNC program. No new dies to cut, no stamping plates to remake. This agility is critical during fleet upfitting development cycles where designs evolve based on field testing feedback.
Consistent Fit Across Vehicle Platforms
CNC control means part 1,000 matches the geometry of part 1 within measurable tolerances. When you're outfitting mixed fleets spanning multiple model years and OEM chassis variations, this consistency simplifies installation and reduces field fitting time.
Frequently Asked Questions
What's the maximum material thickness you can bend?
Our 220-ton press brake handles mild steel up to 0.375" (3/8") thick, stainless steel up to 0.250" (1/4"), and aluminum up to 0.375" across the full 10' bed length. Thicker materials can be formed with reduced bed length utilization. Exact capacity depends on material type, bend radius, and required bend angle.
How accurate are your bend angles?
We maintain bend angle accuracy of ±0.5° on air bending operations and ±0.25° on bottoming operations. Back gauge positioning accuracy is ±0.010" across all axes. These tolerances apply throughout production runs - part 100 matches part 1 within these specifications.
Can you form parts with multiple bends?
Yes. Our 6-axis CNC back gauge automatically repositions between bends according to the programmed sequence. We routinely form brackets and channels with 4-8 bends per part. Complex bend sequences are programmed and validated with our offline software before production begins.
What determines minimum bend radius?
Minimum inside bend radius depends on material type, thickness, and grain direction. General rule is 1x material thickness for mild steel, 1.5x for stainless steel, and 2x for aluminum. Tighter radii risk material cracking on the outer surface. We provide bend radius recommendations during quoting based on your specific material and application.
How do you prevent springback on bends?
Springback compensation is programmed into the CNC controller based on material type, thickness, and grain direction. The controller over-bends by a calculated amount so the final angle after springback matches the target dimension. Material hardness testing and first-article inspection verify compensation values before production runs.
What's your typical lead time for press brake parts?
Simple single-bend parts can be produced in 3-5 business days. Complex multi-bend assemblies requiring program development and first-article approval typically take 7-10 business days. High-volume production runs (500+ pieces) are scheduled based on current shop load but generally complete within 2-3 weeks. Rush service available for urgent fleet deployment needs.
