FREQUENTLY ASKED QUESTIONS
What hole patterns can be drilled or tapped?

Single holes, linear arrays, matrix grids or custom coordinates, as through, blind or counterbored holes. Holes can be drilled, drilled and reamed, or drilled and tapped with metric (M2-M10) or UNC/UNF threads.

How accurate are hole positions?

Hole position tolerance is captured as an engineering requirement and confirmed at review; positional tolerances in the +/- 0.02 to 0.05 mm range are routine for CNC drilling.

What Is CNC Tapping?

CNC Tapping 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.

At VT machining the process runs under full CNC control on calibrated equipment. In practice, that means this: Rigid CNC tapping cuts internal threads in sync with spindle feed for precise, repeatable thread engagement. If you do not have a CAD file yet, the free 3D + 2D builder on this page will produce a drawing we can quote from.

How CNC Tapping 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.

Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.

CNC Tapping Tolerances & Surface Finish

For CNC Tapping, 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.

Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.

Select the alloy you are working in to see material-specific capability, design guidance and applications.

Design Tips for CNC Tapping

A few design choices make a real difference to cost and quality. 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

We complete metal components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.

CNC Tapping Quality & Inspection

Consistent quality comes from disciplined process control. Critical dimensions on metal parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.

Frequently Asked Questions

Can VT machining make custom parts to my drawing?

Yes. CNC Tapping 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.

Which industries use CNC Tapping parts?

CNC Tapping parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise components are required.

What surface finish is achievable on with CNC Tapping?

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 Tapping?

Achievable tolerances for CNC Tapping 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 Tapping and how is it done?

CNC Tapping refers to rigid CNC tapping cuts internal threads in sync with spindle feed for precise, repeatable thread engagement. VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.

What is the typical lead time and minimum order for CNC Tapping?

CNC Tapping 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.
