- Hardened-blank ready
How CNC Gear Cutting Invar Works
Tooth profiles are generated in the Invar blank by a synchronised cutter, then refined to the required accuracy class. Module, pressure angle and helix are programmed from your gear data.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.
Secondary Operations & Finishing
Finished Invar 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 Gear Cutting Invar
We are happy to suggest design tweaks that improve manufacturability. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Invar gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Gear Cutting Tolerances & Surface Finish
Gear features are produced to a specified DIN/AGMA accuracy class, with profile and lead controlled for quiet, durable running under load.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Gear Cutting 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 Invar part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Working with Invar
As a material, Invar is ultra-low thermal expansion. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.
We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.

Does CNC Gear Cutting Invar require dedicated tooling?
Most Invar gear cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Invar a good choice for CNC Gear Cutting?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Gear Cutting. We tune the process to the alloy so the finished Invar gear cutting part meets your dimensional and functional requirements.
What surface finish is achievable on Invar with CNC Gear Cutting?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
What is the typical lead time and minimum order for CNC Gear Cutting Invar?
CNC Gear Cutting prototypes for Invar can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Gear Cutting Invar?
Achievable tolerances for Invar gear cutting depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
