Why CNC Machining?
The most flexible manufacturing process — any geometry, any material, any quantity, with unmatched precision.
- ✓Tightest tolerances — ±0.005mm standard; ±0.001mm on critical features with climate-controlled machining
- ✓Any geometry — 5-axis simultaneous milling produces complex 3D contours, deep pockets, and undercuts impossible by other processes
- ✓Any material — aluminum, steel, stainless, titanium, brass, copper, and engineering plastics — all machined in-house
- ✓No tooling — from CAD to chips in hours — ideal for prototypes and bridge production before casting/forging tooling is ready

Design for Machining
Features that cost more to machine — and alternatives:
- ✓Deep pockets — aspect ratio >4:1 requires special tooling and adds cost — consider redesigning to reduce depth or adding access from multiple sides
- ✓Internal corners — end mills have radius — specify internal corner radii ≥1.5mm (bigger is cheaper); sharp internal corners need EDM
- ✓Threaded deep holes — tap depth >3× diameter requires special taps and risks breakage — specify ≤3× or use thread mills
- ✓Thin walls — walls <1mm in aluminum vibrate and distort — specify ribbed geometry for stiffness
From Prototype to Production
Machining scales from 1 to 100,000 pieces:
- ✓Prototypes (1–10) — CNC direct from CAD — 3–7 day lead time, no tooling
- ✓Low volume (50–5,000) — production CNC with soft jaws, optimized programs, and SPC monitoring
- ✓High volume (5k–100k) — dedicated fixtures, multi-part pallets, and automated loading — machining remains competitive against casting+machining in many cases
- ✓Transition support — when your volume justifies casting or forging tooling, we manage the transition — machining bridge parts while tooling is built
Production & Supply Planning
CNC Machined Components: A Defined Route to Repeat Orders
Agree the process, acceptance criteria and shipment plan before production starts. The quotation identifies the producing site and the controls required for your part.
Confirm the manufacturing route
Choose the stock form, material condition, machining operations and finishing sequence from the drawing.
Approve the inspection plan
Identify critical dimensions, datum references, surface finish and the inspection report required.
Qualify before repeat supply
Define sample approval, drawing revision and lot identification. Agree how material, process or site changes will be reviewed before implementation.
Plan releases and delivery
Confirm order quantities, capacity allocation, packaging and shipping terms against your forecast. Delivery dates and any buffer-stock arrangement belong in the agreed supply plan.
Application Engineering
Where CNC machined components Fit
Typical component uses and the requirements to discuss before quotation. Suitability depends on your design and validation criteria.
Medical device components
Surface condition, cleanability and device-specific qualification requirements.
Industrial automation parts
Datum strategy, fixture access and repeat-order consistency.
Electronic housings and fixtures
Connector features, gasket faces and finish allowances.
Frequently Asked Questions
When is CNC machining the right choice?
Machining is optimal when: you need tight tolerances (casting can't achieve), prototypes or low volume (no tooling cost), parts too complex to cast or forge, or material properties that only wrought stock provides. At volumes above 10,000 pieces, casting + machining of critical faces often becomes cheaper — we'll flag the crossover in your DFM review.
What file formats do you accept?
STEP (.stp/.step) is the gold standard — it transfers 3D geometry with feature data. We also accept IGES, Parasolid (.x_t), SolidWorks (.sldprt), and Inventor (.ipt). For 2D drawings: PDF or DWG. If you only have a physical sample, we can reverse-engineer with CMM and optical scanning.
How do you verify tight tolerances?
Every part gets a CMM dimensional report on critical features. We use temperature-controlled inspection (20°C ±0.5°C) for parts with ±0.01mm or tighter specifications. For PPAP submissions, we run capability studies (Cpk ≥1.33) on designated critical dimensions.
Can you machine parts I supply?
Yes — we regularly machine customer-supplied castings, forgings, extrusions, and fabrications (or parts from your other suppliers). Send us the blank drawings and your machining requirements — we'll quote the machining operation.
