CNC Machining for Electronics and Semiconductors

Small parts, tight tolerances. We machine housings, heat sinks, connectors, and equipment components — from single prototypes to small production runs. Work from your design files or a sample part you provide. Upload your file and get a quote.

Precision Parts for Electronics and Semiconductors

Electronics and semiconductor parts don’t leave much room for error. Features are small, tolerances are tight, and things like heat dissipation, EMI, and cleanliness often decide whether a part works or not. We handle everything from single prototypes to small production runs, and we’re set up for the kind of precision this work needs.

Parts we make regularly for this industry:

  • Enclosures and housings for devices, instruments, and modules
  • Heat sinks and cold plates
  • Connector bodies, RF and waveguide components
  • Semiconductor equipment parts — chamber components, wafer-handling parts, end effectors
  • Test fixtures and jigs
  • EMI shielding and grounding hardware
  • Insulators, standoffs, and mounting brackets

and other electronics and semiconductor parts.

Machining Tolerances

We provide high-precision machining capable of holding tolerances down to ±0.005mm for critical features. This level of accuracy ensures that components strictly adhere to your dimensional specifications and assembly requirements.

Category Description
General Tolerances Unless otherwise specified, standard tolerances for metals are ± 0.127 mm (± 0.005″) in accordance with ISO 2768-m. Tolerances for plastics and composites are generally ± 0.254 mm (± 0.010″) due to material properties.
Min Wall Thickness Metals: 0.8 mm Plastics: 1.5 mm
Minimum Feature Size 0.5 mm
Threads & Tapped Holes M2 / #2-56 (Minimum) We can also machine custom threads.
Surface Finish Unless post-processing is requested, parts are supplied with an as-machined surface of Ra 3.2 μm (125 μin). Visible tool marks may be present.
Edge Condition Broken Edges (Deburred)
Maximum Part Size CNC Milling: 4000×1500×600 mm; CNC Turning: 200×500 mm
Minimum Part Size CNC Milling: 5×5×5 mm; CNC Turning: 2×2 mm

Our Projects

From one-off prototypes to low-volume production parts. We’ve done projects for aerospace, automotive, electronics and industrial fields, all made to meet exact client requirements and tight tolerances.

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). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

Not a problem at all. If you don’t have a 3D design, simply share your concept or requirements with us. We work with experienced partnered product designers who can help convert your ideas, hand-drawn sketches, or reference images into professional, manufacturing-ready 3D models.

Please note that 3D modeling services are subject to an additional design fee based on part complexity.

Absolutely. We offer full reverse engineering services for existing parts. Simply mail us your sample, and our engineering team will take care of the rest — from precise measurement and 3D modeling to final CNC production.

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).
