Equipment and Inspection
Our machining and inspection resources include DMG 80 monoBLOCK, Mazak Integrex i-100S, Matsuura MX-520, Jingshang automatic lathes, and CNC machining centers from Brother, Taichung, and Qiaofeng. Inspection resources include a Hexagon CMM, a TRIMOS 600L height gauge, and video measurement equipment for dimensional verification.
Quality Control and Quotation Information
We can provide CMM reports, first article reports, material certificates, and dimensional inspection planning based on order requirements. NDA coverage is available on request, and sample approval can be arranged before mass production.
To quote nickel alloy machining efficiently, please send a 2D/3D drawing, material grade, tolerance, quantity, and application information. Accepted formats include STEP, IGES, STP, DWG, and dimensioned PDF. This allows our engineering team to review manufacturability, feature risk, inspection needs, and realistic lead time before confirming pricing.
Why Nickel Alloys Are Challenging to Machine
Nickel-based alloys often generate heat, work-harden quickly, and place high loads on cutting tools during milling and turning. For that reason, we do not treat every nickel alloy job the same. XCM reviews the alloy grade, blank form, wall thickness, hole depth, surface requirements, and inspection points before confirming the machining approach.
For components with tight bores, thin walls, sealing surfaces, or freeform geometry, the process plan is confirmed from the drawing first. For selected critical polished features, surface finishes down to Ra 0.015 may be achievable, subject to feature location, access, and process review.
Typical Nickel Alloy Parts We Machine
Rotating and Flow-Control Components
Nickel alloy machining is commonly required for impellers, turbine-related components, shafts, valve bodies, valve trim, sensor components, flanges, and pump parts where corrosion resistance or elevated-temperature stability matters. These parts often combine turning, milling, bore control, sealing faces, and threaded features, so the drawing review focuses on datum strategy, surface finish, and inspection sequence before production begins.
Housings, Cavities, and Connection Hardware
We also machine connectors, cavities, housings, enclosures, and structural blocks in nickel-based alloys for equipment that operates in aggressive fluids or thermally demanding conditions. Depending on the design, these parts may involve deep pockets, intersecting holes, sealing grooves, mounting faces, and mixed tolerance zones that need different machining and measurement methods within the same part.
Precision Components for Demanding Assemblies
For more specialized assemblies, our experience also covers medical components, robotic parts, and automotive components where nickel alloy is selected for specific chemical, thermal, or service-life requirements. These programs are reviewed against the drawing, quantity, traceability needs, and compliance expectations before quotation, especially when the part includes fit-critical bores, thin walls, or post-machining inspection requirements.

Typical Service Conditions and Project Fit
Chemical Processing and Corrosion-Resistant Systems
In chemical processing equipment, nickel alloys are often chosen for parts exposed to corrosive media, pressure, and sealing requirements. Flanges, pump parts, valve components, and fluid-contact housings typically need attention to surface condition, burr control, and dimensional stability on critical interfaces.
Marine, Desalination, and Severe-Service Fluid Systems
For marine and desalination applications, Monel, copper-nickel, and other corrosion-resistant nickel alloys may be used for shafts, connectors, flanges, and flow-control parts. In oil and gas or other severe-service fluid systems, the review normally centers on material grade confirmation, thread quality, sealing features, intersecting holes, and inspection coverage for critical dimensions.
Energy and Thermal Equipment
In energy and thermal equipment, Inconel and similar heat-resistant grades are often used for components that see heat cycling, pressure, or complex geometry. Typical examples include turbine-related parts, sensor housings, and heat-exposed structural details. Where projects touch medical, aerospace, or automotive compliance expectations, suitability remains subject to drawing review and compliance requirements rather than being assumed from the material name alone.
Can you machine Inconel 718, Alloy 718 / 2.4668, and Inconel 625 parts?
Yes. We machine custom Inconel 718, Alloy 718 / 2.4668, and Inconel 625 parts such as shafts, housings, connectors, flanges, and heat-resistant components. The exact machining approach is reviewed from the drawing, material condition, tolerance, and inspection requirements before quotation.
Do you offer Monel 400 and Monel K500 machining, including UNS N04400 / 2.4360?
Yes. We can review Monel 400 and Monel K500 machining projects, including drawings that reference UNS N04400 or 2.4360 where applicable. Please send the required grade, part geometry, and quantity so we can confirm machinability and lead time.
Can you machine Hastelloy C276, C22, B2, and X parts?
Yes. We can review Hastelloy C276, Hastelloy C22, Hastelloy B2, and Hastelloy X machining projects for corrosion-resistant or high-temperature parts used in chemical processing, pump systems, valve assemblies, and severe-service fluid applications. Tooling strategy, inspection points, and delivery timing are confirmed according to the drawing and grade.

Yes. We can review Incoloy 800, Incoloy 800H, Incoloy 800HT, and Incoloy 825 machining for thermal process hardware, furnace-related components, piping details, and corrosion-resistant process parts. The material condition, geometry, tolerance, and service environment are checked before confirming the machining approach.
Do you machine Nickel 200, Nickel 201, pure nickel, and copper-nickel parts?
Yes. We can review Nickel 200, Nickel 201, pure nickel, and copper-nickel parts, including copper-nickel 90/10 applications where the drawing and material callout are clear. Grade, size, tolerance, quantity, and service environment should be provided with the RFQ.
What tolerances can you hold on nickel alloy CNC parts?
Tolerance depends on feature size, geometry, material condition, and inspection method. For selected small precision features, tolerances as tight as ±0.003 mm may be achievable, but that should not be treated as a blanket tolerance for all nickel alloy parts. Critical bores, hole position, and fit features are confirmed from the drawing first.
Can you support prototypes, MOQ 1, and low-volume production?
Yes. MOQ is 1 piece, and prototype lead time is typically around 3-7 days depending on complexity. We also support low-volume and repeat production orders after engineering review for machinability, inspection, and delivery timing.
What drawings and quotation details do you need?
Please send a 2D/3D drawing together with alloy grade, tolerance, quantity, and application details. STEP, IGES, STP, DWG, and dimensioned PDF files are accepted for quotation review so our engineering team can confirm manufacturability, inspection needs, and realistic lead time.
