Custom CNC Machining Service
CNC machining delivers precision, material flexibility and speed — with no tooling investment. Whether you need functional prototypes, bridge production or mold components, our CNC shop machines parts to tight tolerances from metals and engineering plastics. Send your STEP file for a free DFM review — most quotes land within 4 hours.
THE REAL DECISION
Small-Batch Sourcing, Done Right vs. Done Wrong
Low-volume buyers usually hit one of two paths. The wrong one costs months and doubles the budget; the right one gets real production parts in your hand in weeks. Here is what separates them.
The wrong path: a CNC-only shop with no molding synergy
A standalone CNC shop quotes your machined parts — then hands your plastic components to a second vendor. Two factories, two tolerance chains, two quality systems, and a redesign when molded parts behave differently from machined ones. What looked like a saving turns into months of cross-vendor coordination.
The wrong path: tolerance claims with nothing behind them
A ±0.005 mm figure on a quote means nothing without the machines, CMM verification and process control to back it up. Shops that advertise hero tolerances they cannot hold consistently pass the risk to you — the first production run discovers the gap, and your schedule pays for it.

3-Axis, 4-Axis or 5-Axis — Which Do You Need?
More axes mean fewer setups, better surface quality on complex geometry and tighter overall accuracy. Match the axis count to your part geometry.
Machining Capabilities
Process capability ranges for common CNC operations.
| Process | Typical Materials | Common Applications |
|---|---|---|
| CNC Milling | Aluminum, steel, stainless, brass, copper, plastics | Housings, brackets, prototypes, mold components |
| CNC Turning | Aluminum, steel, stainless, brass, POM, PEEK | Shafts, bushings, fittings, threaded parts |
| 5-Axis Machining | Aluminum, steel, stainless, titanium | Complex geometries, undercuts, impellers, mold cores |
| Precision Machining | All of the above | Tight-tolerance features, reference surfaces, fixtures |
What Tolerances Can CNC Machining Hold?
Standard and high-precision options verified by CMM dimensional inspection, first-article inspection and industry-standard compliance.
| Part Category | Standard Tolerance | High-Precision Option |
|---|---|---|
| Metal prototypes | ±0.05 mm (±0.002 in) | ±0.01 mm (±0.0004 in) |
| Plastic prototypes | ±0.05 mm (±0.002 in) | ±0.01 mm (±0.0004 in) |
| Mold machining | ±0.01 mm (±0.0004 in) | ±0.005 mm (±0.0002 in) |
| Micro features | down to 0.5 mm | down to 0.1 mm (micro tools) |
| Surface roughness (Ra) | ≤ 3.2 μm standard | < 0.4 μm for cosmetic parts |
| Hardened steel machining | HRC 45–55 | > HRC 60 with EDM support |
Surface Finishes & Post-Processing
Bead blasting, silkscreening and laser engraving are done on-site; anodizing, electroplating and PVD run with vetted partners.
Bead blasting — uniform matte texture that hides tool marks, ready for painting or anodizing.
Anodizing — hard or decorative anodize in custom colors; Type II decorative, Type III hard coat for wear.
Powder coating & painting — durable color finishes for enclosures, brackets and frames.
Electroplating — chrome, nickel and zinc plating for wear, corrosion and appearance.
High-gloss polishing — mirror finishes down to Ra 0.4 μm for consumer-visible parts.
EMI / RFI shielding — conductive paint, metal linings or shielding gaskets for electronic enclosures.
Silkscreen & laser engraving — logos, serial numbers and UL marks with permanent contrast.
PVD coating — thin, hard, wear-resistant layers for tooling and premium parts.

FAQ
Custom CNC Machining Service — FAQ
What file format should I send?
STEP (.stp) 3D CAD is preferred; if you send other 3D formats we also require a 2D technical drawing for accuracy.
How fast is the quote?
Initial quotes typically land within 4 hours; complex parts may take up to 24 hours.
Is there a minimum order quantity?
No — you can order from 1 piece, which makes CNC ideal for prototyping and low-volume production.
Do you offer volume discounts?
Yes — the larger the quantity, the lower the unit price, with a significant step at around 200 pieces.
What is the maximum part size?
1200 × 800 × 600 mm on 3-axis and 4-axis; 800 × 600 × 500 mm on 5-axis. Larger sizes via vetted partners.
Can you machine micro features below 0.5 mm?
Yes — holes and fine features down to 0.1 mm with micro-cutting tools and adjusted strategies.
Does free DFM really reduce cost?
Yes — DFM optimization typically cuts overall machining cost by 10% to 30% by reducing scrap and simplifying operations.
Can I change the design after quoting?
Yes — modifications before production are free; changes may affect final pricing and lead time, and we re-quote accordingly.
HOW IT WORKS
From Inquiry to Delivery
Upload CAD & Receive DFM
Upload STEP / IGES models securely. We review files and return a free DFM within one day — catching about 90% of design flaws before machining.
Detail Alignment & Quoting
We confirm materials, tolerances and surface finishes with you and offer a reasonable quote — typically within 4 hours, up to 24 hours for complex parts.
Production & Quality Control
Parts are machined on 3-axis, 4-axis and 5-axis centers, then run through strict QC with CMM inspection so parts match the design exactly.
