Custom Precision Aluminum Gearbox Housings and Covers

A set of CNC machined aluminum gearbox components.

We were commissioned by a client to manufacture a complete set of custom aluminum gearbox components, including the main housing, transmission covers, and internal support plates. These parts are designed for automotive. While they may look like standard castings, they are actually fully CNC-machined from solid aluminum blocks to ensure maximum strength and weight reduction.

The project required transforming aluminum blocks into complex, lightweight assemblies with extremely tight tolerances for internal gear alignment. Our task was to ensure that despite the intricate thin-wall design and multiple bearing bores, each part remained dimensionally stable and ready for immediate assembly.

Project Details

Part type: Custom Aluminum Gearbox Housing / Transmission Case Cover

Material: Aluminum Alloy

Machining Process: CNC Milling

Surface Finish: As-Machined

Quantity: 100 pcs

Lead Time: 48 day

Quality Assurance

  • CMM Inspection: Verification of geometric tolerances, including circularity, parallelism, and hole positions.
  • Fitment Testing: Representative samples were checked for seamless fit between the housing and covers.
  • Thread Inspection: Ensuring all mounting holes are clean and meet the specified pitch requirements.

The finished transmission housing components perfectly matched the client’s design.

Custom CNC Automotive Part Machining

Our Manufacturing Capabilities

5-axis CNC milling machine cutting an aluminum block during the manufacturing process.

Capabilities include 3-Axis, 4-Axis, and 5-Axis CNC Milling, as well as CNC Turning operations. Standard materials processed include Aluminum alloys, Stainless Steel, Titanium, etc. and Engineering Plastics. Available secondary operations include Anodizing, Powder Coating, Bead Blasting, and Laser Engraving.

Capacity supports requirements ranging from single-unit Rapid Prototyping to Low-Volume Production runs (1-1,000+ units).

Factory Quality Assurance

A standardized Quality Management System (QMS) is applied to all manufacturing orders, regardless of part complexity or production volume. The following inspection stages are mandatory for every CNC machining project:

  • Material Verification: Raw material certification (chemical composition and mechanical properties) is verified upon receipt to ensure compliance with material specifications.

  • First Article Inspection (FAI): The first unit from any production run undergoes a full dimensional report to validate the machining setup and programming before volume processing begins.

  • In-Process Monitoring: Periodic checks are conducted during the machining cycle to monitor tool wear and ensure dimensional consistency is maintained throughout the batch.

  • Final Inspection: Completed components undergo a final dimensional and cosmetic verification using CMM (Coordinate Measuring Machine) and calibrated manual instruments prior to packaging.

FAQs About CNC Machining Services

No. We support projects of all sizes, from a single prototype unit to low-volume production runs.

Standard lead times are typically 10–15 business days. Expedited services (Rapid Prototyping) can be completed in as little as 3–5 business days, depending on part complexity and material availability.

In most cases, we source materials from our approved suppliers to ensure quality control. However, we can machine customer-supplied materials for specialized alloys or specific requirements upon engineering review.

Unless otherwise specified, our general tolerance standard is ISO 2768-m (±0.125 mm) for metals and ±0.25 mm for plastics. Precision tolerances ±0.005 mm are achievable but must be explicitly stated in 2D technical drawings.

Our facility can accommodate parts up to 4000 x 1500 x 600 mm for milling and Ø200 mm x 500 mm for turning.

Yes. We can install inserts (e.g., Helicoils, PEM fasteners) and perform basic mechanical assembly of machined components prior to shipment.

To provide an accurate quote, we require a 3D CAD file (STEP, IGES, or X_T format). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

We take IP protection seriously. All files are stored securely, and we are willing to sign a Non-Disclosure Agreement (NDA) prior to receiving your data.

Yes. We can provide material certificates (COA) and dimensional inspection reports upon request. Please specify this requirement when placing your order.

We ship globally using major carriers (DHL, FedEx, UPS).
