VT machining offers CNC Reaming for Inconel 718 (UNS N07718 / 2.4668), typically supplied solution-treated or aged. Precipitation-hardened superalloy; strongest of the common Inconels to ~650 °C.
CNC Reaming Notes for Inconel 718
Inconel 718 can rub and close up behind the reamer, so we leave a consistent stock allowance and keep the reamer cutting rather than burnishing.
For estimating, a 100 × 100 × 10 mm block of Inconel 718 weighs about 0.82 kg.
Starting Parameters for CNC Reaming Inconel 718

| Feed | 0.075-0.24 mm/rev |
| Spindle speed, Ø10 mm | 160-320 rpm |
| Insert / tool class | ISO H — CBN or fine-grain carbide |
| Coolant | High-pressure emulsion; ceramic inserts run dry for roughing |

Which industries use CNC Reaming Inconel 718 parts?
CNC Reaming Inconel 718 parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Inconel 718 components are required.
What tolerances can you hold for CNC Reaming Inconel 718?
Achievable tolerances for Inconel 718 machining 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 surface finish is achievable on Inconel 718 with CNC Reaming?
Surface finish on Inconel 718 is controlled to your specification; we confirm the achievable Ra against your callout.
Can VT machining make custom Inconel 718 parts to my drawing?
Yes. Inconel 718 machining 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.
What is CNC Reaming Inconel 718 and how is it done?
CNC Reaming Inconel 718 refers to reaming finishes drilled holes to a precise diameter and smooth surface in a single controlled pass. Applied to Inconel 718 — high-temperature strength and oxidation resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
