Inconel Machining Services for Large Parts
AS9100 & ISO 9001 Certified | ITAR Registered
Greno Industries provides Inconel machining services for extreme environments where conventional steels fail, requiring advanced machining expertise, rigid equipment, and highly controlled manufacturing processes.
With decades of experience machining Inconel 600, 625, 718, X-750, and other high-performance nickel alloys, Greno Industries specializes in producing complex, tight-tolerance components for demanding applications. Our capabilities include CNC milling, large-diameter turning, deep-hole gun drilling, and end-to-end manufacturing support for mission-critical parts.
Why Choose Greno for Inconel Machining?
Inconel’s high strength, work‑hardening, and low thermal conductivity require specialized machining strategies. Many shops don’t have the tools, equipment, or experience, but that’s not the case at Greno Industries.
For example, our machinists understand how Inconel responds to cutting forces, heat, and tool pressure. This allows our skilled personnel to maintain dimensional accuracy and surface integrity even under aggressive conditions.
Greno also combines advanced machining technology with decades of experience machining difficult nickel-based superalloys for highly regulated industries. Customers choose us for:
Precision Inconel machining expertise
Large-format machining capabilities
In-house deep-hole gun drilling
Tight-tolerance manufacturing
Defense and aerospace experience
Rapid-response manufacturing support
End-to-end manufacturing solutions
Our certifications and qualifications include:
AS9100:2016

From prototype development to full production manufacturing, Greno Industries delivers precision Inconel machining services designed for performance, reliability, and demanding operating environments.
Examples of Inconel Parts Machining
Inconel’s strength at elevated temperatures, resistance to oxidation, and ability to withstand corrosive environments make it ideal for:
Steam turbine parts
Exhaust and combustion hardware
High-temperature custom fasteners
Pressure-retaining components
Oil and gas downhole tools
Heat-resistant housings and brackets
Naval and marine hardware
At Greno Industries, every machined Inconel part is inspected using our calibrated metrology equipment to ensure compliance with customer specifications.
CNC Milling for Large Inconel Parts
Greno’s CNC milling services can machine Inconel parts with complex geometries, tight tolerances, and demanding surface‑finish requirements.
Our 3‑axis and 4‑axis equipment supports:
Precision pocketing and contouring
Multi‑face machining
Tight‑tolerance bores and slots
Thread milling and tapped features
Complex profiles and structural features
Inconel’s tendency to work‑harden requires rigid setups, sharp carbide or ceramic tooling, and carefully controlled feeds and speeds. That’s why Greno’s machinists use optimized toolpaths, high‑pressure coolant, and thermal‑management strategies to prevent tool wear, maintain surface finish, and avoid heat‑induced distortion.
CNC Milled Inconel Parts
Examples of machined Inconel parts include:
High‑temperature housings
Gas turbine rings and brackets
Exhaust system components
Aerospace and naval hardware
Heat‑resistant mounting plates
Large Diameter Turning for Inconel Parts
Greno’s large-diameter turning services are ideal for heavy, high‑strength Inconel components. Our turning centers provide the rigidity that’s needed to machine nickel superalloys without chatter, deflection, or thermal instability.
Our capabilities include:
High‑torque roughing of forged or hot‑rolled stock
Precision finishing to tight tolerances
Threading, including ACME, UN, and custom profiles
Boring and facing of large internal diameters
Concentricity and roundness control, critical Geometric Dimensioning and Tolerancing (GD&T) controls for rotating and mating components
Inconel’s low thermal conductivity causes heat to concentrate at the cutting edge, accelerating tool wear. That’s why Greno’s machinists use advanced tool geometries, stable workholding, and controlled chip‑breaking strategies to maintain accuracy and prolong tool life.
Turned Inconel Parts
Examples of large-diameter turning for Inconel parts include:
Sleeves and bushings
Rings and flanges
High‑temperature shafts
Pressure‑retaining components
Naval and marine fastener bodies
Gun Drilling for Inconel Fasteners and Components
Inconel gun drilling is an especially challenging machining operation because of Inconel’s strength and heat‑retention characteristics. Greno’s in‑house gun drilling capability is powered by DeHoff deep‑hole drilling machines and allows us to produce straight, accurate bores in Inconel components.
Greno can gun drill:
Up to 60 inches deep
Diameters up to 1.25 inches
Inconel 718, 625, 600, X‑750, and other nickel alloys
Gun Drilled Inconel Parts
Applications for Inconel gun drilling include:
Long Inconel fasteners
High‑temperature studs and bolts
Turbine components with internal cooling passages
Cylindrical housings requiring deep bores
Greno’s ability to combine large-diameter turning, CMC milling, and gun drilling in‑house reduces lead times and ensures consistent quality across every operation.
Ask Greno for Inconel Machining
Inconel’s exceptional strength, corrosion resistance, oxidation resistance, and thermal stability make it ideal for turbine components, pressure-retaining systems, exhaust hardware, custom fasteners, naval systems, and high-temperature industrial assemblies. However, these same properties also make Inconel one of the most difficult materials to machine.
Unlike conventional materials, Inconel work-hardens rapidly and retains heat at the cutting edge, creating significant machining challenges. Greno’s machinists understand how nickel superalloys respond to cutting forces, heat generation, chip load, and tooling pressure, allowing us to maintain dimensional accuracy, structural integrity, and surface quality throughout the machining process.
