Our custom CNC machined aluminum knobs are specifically engineered for the high-end audio and smart home markets, where a knob serves as the most frequent touchpoint between the user and the device. Our client required a bespoke solution to replace generic plastic components with a weighted, high-precision metal knob that reflects their brand’s luxury positioning.

The challenge was to achieve a flawless surface finish while maintaining ultra-tight tolerances for a smooth, wobble-free rotation.By utilizing multi-axis CNC turning, we achieved a refined geometry with a precision tolerance of ±0.05mm. This ensures a secure, wobble-free installation that enhances the overall perception of the device. The 180# bead blasting process removes all machining marks, creating a silky, diffused surface, while the matte black anodized layer provides long-term durability and a premium tactile response.

Project Details

Part type: Bespoke Minimalist Aluminum Rotary Knobs

Material: Aluminum 6061

Surface Finish: Matte Black Anodizing

General Tolerance: ± 0.05 mm

Quantity: 220 pcs

Lead Time: 10 day

Versatile Textures & Vibrant Colors

Precision CNC machined aluminum knobs with radial brushed CD pattern in red and silver finishes.

While the minimalist matte black is a classic, we also offer a variety of surface textures to meet different industrial design needs. As shown in the image, these knobs feature a Radial Brushed (CD Pattern) top, which creates a dynamic light-catching effect. We provide high-consistency anodizing in vibrant colors like Crimson Red and Classic Silver, allowing brands to differentiate their product tiers through visual cues.

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

Coordinate Measuring Machine (CMM) inspecting the dimensional accuracy of a custom CNC machined part.

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.

Order Fulfillment Process

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). Shipping terms are typically Ex Works (EXW) or DAP, depending on the agreement.
