Custom Machined Brackets From Bar and Plate
DEK machines L-brackets, angle mounts, sensor and camera brackets, motor mounts and clevis brackets in aluminum, stainless and alloy steel, from solid bar and plate.
Tight hole position matters when the bracket locates a bearing, a lens or a sensor rather than just holding a panel. Prototypes ship in 3–5 days, small batches in 4–7 days. Brackets are one of the most requested items in our custom CNC machined parts catalogue.
Types of Brackets We Machine
From L-brackets to structural mounts, milled from aluminum, stainless or alloy steel bar and plate.
-
L-Brackets & Angle BracketsTrue 90° faces, squareness 0.02 mm over 100 mm, from plate or bar. -
Motor & Gearbox MountsMounts for motors, pumps, actuators; bolt patterns ±0.02 mm position. -
Sensor & Camera BracketsSensor, camera, lidar, antenna brackets with slotted holes, shim faces. -
Clevis & Pivot BracketsPivot brackets with reamed or bored pin holes held to H7. -
Linear-Rail & Frame BracketsLinear-rail, extrusion and frame brackets for automation cells. -
Structural Brackets4140 or 17-4 PH brackets for high-load, fatigue-critical assemblies.
Bracket Materials, Processes & Tolerances
What CNC machined brackets are made of, how they are cut, the tolerances they hold and the finishes applied.
Design Tips for Machined Brackets
Walls, radii, datums and finish callouts decide cost and whether a bracket holds flatness after machining.
-
Minimum Wall Thickness
Keep walls at or above 1.5 mm in aluminum and 1.0 mm in steel; thinner walls chatter and lose flatness.
-
Internal Corner Radii
Specify internal radii of at least one third of pocket depth; sharp corners force small cutters and raise cost.
-
Datum on the Mounting Face
Put the datum on the mounting face and the two locating holes, and tolerance everything else from there.
-
Slots vs Locating Holes
Use slots where the mating part has its own tolerance; keep ±0.02 mm true position for the two locating holes.
-
Stress-Relieved Plate
For thin, long brackets, specify stress-relieved plate: 6061-T651 and MIC6 stay flatter after machining.
What to Call Out on Your Drawing
-
Anodizing Thickness
State Type II 10–15 µm or Type III 25–50 µm: hard coat grows the dimension and can close a tolerance hole.
-
Features That Matter
Send a STEP or PDF drawing with material, quantity, finish and the features that actually matter to the bracket's function.
-
Post-Finish Operations
Flag a ground face or post-anodize reamed hole; see our guide on machining a bracket with tight tolerance.

Why DEK for Custom Brackets
Custom brackets manufacturing has been part of DEK's work since 2002, with engineer review and measured inspection.
-
Machining Since 2002
DEK has machined custom brackets since 2002, from single prototypes to 5,000-piece production runs with no MOQ.
-
Engineer-Reviewed Quotes
Every drawing is checked by an engineer before quoting, so a ground face or post-anodize reamed hole is priced right.
-
Spectrometer-Checked Plate
Incoming plate is spectrometer checked, so 6061, 7075, 4140 or stainless grades match the drawing before cutting.
-
CMM-Verified Holes
Hole patterns are verified on CMM against ±0.02 mm true position, and inspection reports are available on request.
Certified Quality System
DEK is ISO 9001:2015, ISO 13485 and AS9100D certified. An engineer reviews every bracket drawing and quotes within 6 hours.
