Custom Machined Mounting Brackets

Brackets That Line Up First Time

A mounting bracket's only job is to connect two things rigidly and in the right place. So the part that matters most isn't the shape — it's the bolt-hole pattern: hole positions, spacing and the mating-face flatness that decide whether it bolts straight on or fights you on site. Machined from solid plate or billet, a CNC bracket is one rigid piece (no welded distortion) with holes held true to position.

Custom Bracket Specifications

Attribute	Capability
Materials	6061 & 7075 aluminium, mild & alloy steel, stainless
Process	3-axis & 5-axis milling from plate or billet
Bolt-hole position	True position from a common datum; interchangeable across a batch
General tolerance	ISO 2768-m / -f; ±0.025 mm on critical features
Finishes	Anodize (clear/black/colour), powder coat, zinc plate, bead blast
Quantity	One-off to production batch

Machined, Formed or Cast — Choosing the Process

"Custom bracket" can mean several processes, and the cheapest one depends on the bracket. As a custom parts maker we pick the right one rather than forcing everything into a mill:

Process	Best for	Notes
CNC machined from solid	Rigid, precise, complex, low–mid volume	One piece, no weld distortion, tight tolerance — our default
Formed sheet metal (laser + bend)	Simple flat / folded brackets, higher volume	Cheaper per part for plain brackets — ask us and we'll quote it
Cast	Complex shapes in large quantities	Tooling cost amortised over volume

For most one-off, replacement and precision brackets, machined-from-solid wins — no tooling, fast, and stronger than a folded part. For simple high-volume brackets, ask about formed sheet metal.

Bracket Types We Machine

By shape — the common geometries, machined from solid or formed to suit:

• L-brackets (angle) — the 90° structural connector
• Z-brackets & offset brackets — span two planes at a step
• U-brackets / channel mounts — straddle and clamp a part
• Gusseted brackets — with a rib for high load
• Flat-mount / base plates — single-face bolt-down

By job — typical applications:

• Motor & pump mounts — with concentric pilots and bolt circles
• Sensor & electronics brackets — light, precise mounts
• Motorsport & chassis brackets — billet, anodized (see automotive CNC parts)
• Machine & automation mounts — fixturing and guarding

Material & Finish Choice

6061-T6 is the default — light, strong, anodizes well. Step up to 7075-T6 for highly loaded brackets, or steel/stainless where strength or environment demands. Anodizing or powder coat adds corrosion protection and a finished look. Flatness and hole position are verified on inspection.

Design Tips for a Strong Bracket

A few choices at the design stage decide whether a bracket lasts — guidance most "custom bracket" pages skip, even though it's where parts fail:

• Fillet the inside corners. Sharp internal corners concentrate stress and are where brackets crack — a generous radius is the single biggest durability win.
• Add a rib or gusset, not just thickness. A rib stiffens a bracket far more than extra wall, for less weight.
• Keep walls consistent to avoid distortion and chatter marks.
• Reference bolt holes off one datum so they stay true to position.
