CNC Reaming Alloy 42 is part of VT machining's grade-specific capability. Alloy 42 is matched/low thermal expansion for sealing, and we combine controlled machining with material-aware setup to produce parts that meet your specification.
CNC Reaming Capability for Alloy 42
- Matched/low thermal expansion
- Glass-to-metal sealing
- Tolerance to ±0.01 mm
- Electronics-grade
Machining Alloy 42 with CNC Reaming
Alloy 42 behaves predictably under CNC Reaming once parameters are dialled in: machinability is moderate; gummy, requires sharp tooling and careful thermal control, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of Alloy 42 run consistently from one batch to the next.
Secondary Operations & Finishing
Finished Alloy 42 parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Design Tips for CNC Reaming Alloy 42
We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Alloy 42. If you send your model early, we will return practical DFM feedback before you commit to production.
Why Alloy 42?
Alloy 42 is chosen when a part needs what this grade offers — it is matched/low thermal expansion for sealing. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Reaming Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Alloy 42 part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Reaming Tolerances & Surface Finish
For CNC Reaming, 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Applications of CNC Reaming Alloy 42
Customers order CNC Reaming Alloy 42 components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

What tolerances can you hold for CNC Reaming Alloy 42?
Achievable tolerances for Alloy 42 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.
Which industries use CNC Reaming Alloy 42 parts?
CNC Reaming Alloy 42 parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Alloy 42 components are required.
Why is Alloy 42 a good choice for CNC Reaming?
Alloy 42 is matched/low thermal expansion for sealing, which makes it well suited to CNC Reaming. We tune the process to the alloy so the finished Alloy 42 machining part meets your dimensional and functional requirements.
What is CNC Reaming Alloy 42 and how is it done?
CNC Reaming Alloy 42 refers to reaming finishes drilled holes to a precise diameter and smooth surface in a single controlled pass. Applied to Alloy 42 — matched/low thermal expansion for sealing — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Reaming Alloy 42 require dedicated tooling?
Most Alloy 42 machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
