VT machining offers CNC 5-Axis Machining 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 5-Axis Machining Notes for Inconel 718
For a hard-to-cut grade like Inconel 718, multi-axis machining reduces the number of setups, so there are fewer re-clamps and less time spent cutting.
For estimating, a 100 × 100 × 10 mm block of Inconel 718 weighs about 0.82 kg.

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 5-Axis Machining Inconel 718 and how is it done?
CNC 5-Axis Machining Inconel 718 refers to five-axis machining orients the tool to complex geometry in one setup, reducing fixturing and improving accuracy. 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.
Does CNC 5-Axis Machining Inconel 718 require dedicated tooling?
Most Inconel 718 machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Inconel 718 a good choice for CNC 5-Axis Machining?
Inconel 718 is high-temperature strength and oxidation resistance, which makes it well suited to CNC 5-Axis Machining. We tune the process to the alloy so the finished Inconel 718 machining part meets your dimensional and functional requirements.
