Explore EDM MachiningWhich CNC Machining Process Does Your Part Need?
The process is chosen by the part's geometry, not by preference: round parts about one axis are turned, prismatic parts with pockets and faces are milled, long slender parts under Ø32 mm go to Swiss-type, and features a cutter cannot reach go to EDM. The table below is the same decision our engineers make on every RFQ. Send a drawing and we confirm the route with your quote inside 24 hours.
| Process | Use it when the part is | Tolerance | Size range |
|---|---|---|---|
| CNC milling services | Prismatic — housings, brackets, manifolds, base plates, heat sinks, mould cavities | ±0.01 mm → ±0.001 mm on 5-axis | To 1,500 mm X travel |
| CNC turning services | Round about one axis — shafts, pins, bushings, sleeves, rings, threaded bodies | ±0.01 mm → ±0.001 mm on Swiss | Ø1 – 800 mm |
| Multi-axis machining | Compound curves, undercuts and turbine or implant profiles that must be cut in one clamping | ±0.001 mm | To 1,000 mm X travel |
| Swiss machining | Small and slender — longer than about 8× its diameter, or under Ø32 mm | ±0.001 mm | Ø1 – 32 mm |
| Micro-machining | Carrying features measured in microns — holes, walls or slots below 1 mm, where micro machining tooling is needed | ±0.001 mm | Features < 1 mm |
| Wire and sinker EDM | Hardened above 55 HRC, or needs square internal corners a rotating cutter cannot produce | ±0.001 mm | Wire 0.02 – 0.30 mm |
| Laser cutting and sheet metal | Flat, cut from sheet then bent — enclosures, panels, brackets, chassis | ±0.1 mm | To 2,000 × 4,000 mm |
| Every process above runs to the same quality system: general features to ±0.01 mm under ISO 2768-m, precision features to ±0.005 mm, critical dimensions to ±0.001 mm with Cpk ≥1.67, verified on Zeiss CMM equipment. Prototypes ship in 3–5 business days, volume production in 10–15, with 48-hour express available. Most parts use more than one process — a turned body with milled cross-holes is quoted as a single part, not two. | |||

Plan Your CNC Machining Project
The essential drawing, material and purchasing details for a clear machining quote.
Choose the Process for Your Part
CNC milling suits housings, pockets and brackets. Turning suits shafts, bushings and other rotational parts. Multi-axis machining improves access to complex faces; Swiss machining supports slender components.
Specify What Matters
Send a 3D model and a dimensioned drawing with material grade, quantity, critical tolerances, surface finish and inspection requirements. Identify functional fits and sealing faces so the engineering review can focus on performance.
Control Machining Cost
Material, cutting time, setups, batch size and inspection scope determine the quote. Deep pockets, thin walls and unnecessarily tight tolerances can increase cost. Reserve precision callouts for functional features and discuss alternatives during DFM review.
From Drawing to Delivery
- Submit your CAD files and purchasing requirements.
- Review manufacturability, price and delivery timing with the engineering team.
- Approve the material, finish and inspection plan before machining.
- Confirm sample approval and production requirements before shipment.
