CNC Gear Grinding Invar from VT machining delivers precision Invar parts produced to your exact drawing. Gear grinding finishes hardened gear teeth to high accuracy class for quiet, durable transmission, and we tune every parameter to the behaviour of Invar, which is ultra-low thermal expansion.
CNC Gear Grinding Capability for Invar
- DIN/AGMA accuracy class
- Profile & lead correction
- Hardened-gear finishing
- Low transmission noise
How CNC Gear Grinding 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.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
CNC Gear Grinding 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.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Working with Invar
Invar is ultra-low thermal expansion. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
Secondary Operations & Finishing
Most Invar parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Design Tips for CNC Gear Grinding Invar
Small design adjustments often cut cost and lead time. 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 Grinding Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Applications of CNC Gear Grinding Invar
Invar parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Gear Grinding Invar
Starting your project takes one email. Send your CAD or 2D drawing, the Invar grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

What gear accuracy class can you achieve on Invar?
Gear accuracy is specified to DIN/AGMA classes appropriate to the application. Profile and lead are controlled so Invar gears run accurately and quietly under load.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar Invar gear cutting 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 Gear Grinding Invar and how is it done?
CNC Gear Grinding Invar refers to gear grinding finishes hardened gear teeth to high accuracy class for quiet, durable transmission. Applied to Invar — ultra-low thermal expansion — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is Invar a good choice for CNC Gear Grinding?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Gear Grinding. We tune the process to the alloy so the finished Invar gear cutting part meets your dimensional and functional requirements.
