CNC Machined Brackets
Brackets are one of the most commonly CNC machined parts — and one where small design choices drive most of the cost. We machine mounting, structural, and angle brackets in aluminum, steel, and titanium for prototypes through production.
What is a CNC machined brackets?
A bracket is a load-carrying part that connects, supports, or positions one component relative to another. CNC machining is preferred over sheet metal or casting when the bracket needs tight hole positions, threaded features, flatness on mating faces, or a finish-machined surface — all of which are common in aerospace, robotics, and instrumentation. Machined brackets hold position tolerances that bent sheet-metal brackets cannot.
Common materials
The default for brackets — light, stiff, cheap to machine, and anodizable for corrosion resistance.
When the bracket carries high load at minimum weight (aerospace, motorsport).
For corrosion resistance, wash-down, or marine and medical environments.
Maximum strength-to-weight for flight and structural brackets.
Typical tolerance
±0.02 mm
Hole-position tolerances on mounting patterns are typically the critical feature; we hold ±0.02 mm routinely and tighter with fixturing.
How we machine them
Covers the majority of bracket geometry — faces, pockets, hole patterns.
For brackets with features on angled faces, machined in one setup for better accuracy.
Type II/III anodize, powder coat, or passivation for corrosion and appearance.
Design tips that lower cost
Add radii to internal corners
Internal corners can't be machined sharp — design a radius of at least ⅓ the pocket depth so a larger, faster tool can be used. It cuts cost with no functional downside on most brackets.
Keep walls ≥ 0.8 mm
Thin bracket walls chatter and deflect during cutting. For aluminum keep walls above 0.8 mm; for steel above 1.0 mm to avoid distortion and a poor finish.
Tolerance only the mounting interface
The holes and faces that mate to other parts need tight tolerance — the rest of the bracket does not. Applying ±0.02 mm everywhere multiplies cost for no benefit.
Design for a single setup where possible
Brackets needing features on five faces require multiple setups (or 5-axis). Grouping critical features onto one or two faces keeps cost down and accuracy up.
Industries we machine brackets for
Brackets — frequently asked
What is the most cost-effective material for CNC machined brackets?
Aluminum 6061-T6 — it machines fast, is inexpensive, and anodizes well. Only move to 7075, stainless, or titanium when load, corrosion, or weight specifically demand it.
Can you machine brackets with threaded holes?
Yes. We cut threads directly (M2 and up, plus UNC/UNF) or install threaded inserts (heli-coil, press-fit) for higher pull-out strength in aluminum.
Do you offer low-volume bracket runs?
Yes — we have no minimum order quantity. A single prototype bracket is fine, and unit price drops sharply at production volume.
