About This Part
This automotive transmission case bracket is machined from one billet of high-strength aluminum 2014-T4. The material gives the bracket its stiffness at low weight, and the natural (clear) anodize finish protects the surface with a thin film that does not shift assembly dimensions.
A 9-axis mill-turn center completes the outer profile, the precision dimensions, and every hole position in one clamping, so datum relationships stay true without refixturing error. Features a cutting tool cannot reach, such as internal windows and narrow slots, are cut by slow-wire EDM, which removes material with no contact force on the part. Seating faces that need a fine finish are completed by ultra-precision grinding.
Every dimension is verified on Hexagon and Zeiss CMMs to the ±0.005 mm standard tolerance, and a full first-article inspection report is available with each order. Send your drawing for DFM feedback and a quotation within 24 hours.
Why Machine It at KGL
Five-Axis Fleet
100+ CNC machines including 11 five-axis centers run complex geometry in single setups, so tolerances do not stack up across refixturing.
Verified Accuracy
±0.005 mm standard on metals, plastics, and carbon fiber composite, verified on Hexagon and Zeiss CMMs (0.0015 mm accuracy).
Fast Prototypes
Engineering feedback with every quotation; prototype parts typically machined in 15 to 25 days.
One Supplier, End to End
Material sourcing, machining, heat treatment coordination, finishing, CMM inspection and export packaging under one roof.
Part-Specific Advantages
- Machined from one billet of 2014-T4 aluminum: high strength at low weight with a continuous structure.
- 9-axis mill-turn in a single setup keeps profile, precision dimensions, and hole positions aligned.
- Slow-wire EDM opens internal windows and narrow slots where cutting tools cannot reach, with no contact force.
- Ultra-precision grinding finishes seating faces; natural anodize keeps dimensions stable through assembly.
Typical Applications
- Automotive transmission case mounting brackets
- Powertrain and drivetrain aluminum brackets
- Structural brackets for industrial equipment

Common Questions
Why is 2014-T4 used for this bracket?
2014 is a high-strength aluminum-copper alloy. In the T4 temper it keeps a rigid, stable structure at low weight, and the natural anodize layer protects the surface without shifting critical dimensions.
Why combine 9-axis mill-turn with slow-wire EDM?
The mill-turn center finishes the outer profile, precision dimensions, and hole positions in one clamping. Internal windows and narrow slots sit outside tool reach, and slow-wire EDM cuts them with no contact force on the part.
