CNC Milling BuilderConfigure CNC milled metal parts: plate or block stock with milled pockets, grooves, edge steps, and surface finishing options. Every builder includes the Freeform Corner & Region Editor: cut or add material of any shape directly on the 3D model, then submit an RFQ.This tool is for visual configuration only. Final dimensions, tolerances, materials, coatings, and manufacturability will be reviewed from your drawing or specification.
Paste a configuration JSON (from Export) or a copied RFQ summary. The product and all recognized parameters are applied automatically; unknown parameters are listed and skipped.
Answer the choices below step by step — every value comes from the real option list, so it always renders.

FREQUENTLY ASKED QUESTIONSWhat milled features can I configure?
Edge grooves, center pockets/cavities and edge steps with adjustable width and depth on plate or block stock, plus surface treatments such as anodizing, nickel plating, powder coating and black oxide. 3-, 4- and 5-axis setups can be requested.
What tolerances and surface finish can milling hold?
Standard milled tolerances of +/- 0.05 mm, tighter on request, with surface grades from roughing (Ra 3.2) down to fine finishing (Ra 0.4). Tight-tolerance features are reviewed against your drawing.
CNC Milling is a subtractive process in which a rotating multi-flute cutter removes material from a fixed workpiece to create flat faces, pockets, slots, bosses, holes and free-form 3D surfaces. Because the tool can approach from several directions on 3-, 4- and 5-axis machines, complex prismatic parts are produced in very few setups.
Our shop runs CNC Milling daily, which means proven parameters and short setup times. Multi-axis milling cutters remove material to produce prismatic features, pockets, slots and contoured 3D surfaces. Upload your geometry — or draw it in the free builder on this page — and we will come back with pricing and DFM notes.
How CNC Milling Works at VT machining
Rotating multi-flute cutters remove material as the metal workpiece is driven through programmed tool paths on 3-, 4- or 5-axis machining centres. Climb milling, step-over and depth-of-cut are set so chip load stays in the ideal band for the alloy.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.

CNC Milling Tolerances & Surface Finish
For CNC Milling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.

CNC Milling by Metal — Choose Your Material
Each material page covers how CNC Milling behaves in that alloy, what tolerances are realistic and where the parts are used.
We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in metal. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Finished metal parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
CNC Milling Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every metal part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Starting your project takes one email. Send your CAD or 2D drawing, the metal grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.
Have a drawing ready? Send it with your quantity and material for a quotation, usually within one business day.
Yes. CNC Milling is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Does CNC Milling require dedicated tooling?
Most CNC Milling work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Milling?
CNC Milling prototypes for can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What surface finish is achievable on with CNC Milling?
Surface finish on the part is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Milling?
Achievable tolerances for CNC Milling depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What is CNC Milling and how is it done?
CNC Milling refers to multi-axis milling cutters remove material to produce prismatic features, pockets, slots and contoured 3D surfaces. VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
