CNC Bending Service

How It Works

Precision CNC Press Brake Bending

CNC press brake bending forms sheet metal by pressing it between a punch and die. The CNC backstop positions the sheet precisely, and a depth-controlled ram bends to the programmed angle. FYORD uses Amada and Trumpf press brakes with automatic angle correction — what you specify is what you get.

Bending is typically added to laser-cut or waterjet-cut blanks in the same order, saving time and freight. Our team programs bending sequences to avoid tool collisions on complex formed parts.

Design Guidelines

Flat Pattern Rules for CNC Bending

Design the flat pattern correctly and your bent part will hit all tolerances first time.

📏 Minimum Flange Length

Minimum flange = 3× material thickness. For 3 mm sheet, minimum flange = 9 mm. Shorter flanges cannot be gripped by the die and may slip during bending.

🕳️ Holes Near Bends

Keep holes at least 2× material thickness + bend radius away from the bend line. Holes too close distort during bending. If unavoidable, place the hole after bending.

📐 Bend Allowance

FYORD calculates flat-pattern bend allowance automatically using K-factor: 0.33 for MS, 0.38 for Al, 0.4 for SS. Upload the 3D folded model — we unfold it for cutting.

🔲 Relief Cuts

Add rectangular relief notches at the ends of each bend line when the bend intersects another flange. Relief size = 2× material thickness × 2× material thickness minimum.

📋 Bending Sequence

Complex parts may need bends in a specific order to avoid tool collisions. Our engineers plan the sequence — just provide the 3D model and we'll handle it.

📁 File Formats

Upload a STEP or DXF flat pattern. Alternatively, upload the 3D folded model in STEP format and we will unfold it. Always include a PDF drawing showing all bend angles.

Material	Max Thickness	Min Bend Radius	K-factor
Mild Steel (CR/HR)	10 mm	0.8× thickness	0.33
Stainless Steel 304	8 mm	1.0× thickness	0.40
Aluminium 5052	12 mm	1.5× thickness	0.38
Aluminium 6061-T6	8 mm	2.0× thickness	0.42

💡 Pro tip: Order laser cutting + bending together. We machine both on the same job card, saving 1–2 days of lead time and inter-factory freight.
