CNC Gear Hobbing Kovar is a core capability at VT machining. We combine controlled gear cutting with material-aware setup for Kovar — an alloy that is matched thermal expansion for glass/ceramic seals — to produce parts that meet your specification first time.
CNC Gear Hobbing Capability for Kovar
- Spur & helical gears
- Module range support
- Pre-grind accuracy
- High productivity
How CNC Gear Hobbing Kovar Works
Tooth profiles are generated in the Kovar 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.
Secondary Operations & Finishing
Most Kovar 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 Hobbing Kovar
Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Kovar gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Kovar
Kovar is matched thermal expansion for glass/ceramic seals. 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.
CNC Gear Hobbing 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.
CNC Gear Hobbing 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.
Applications of CNC Gear Hobbing Kovar
Kovar 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 Hobbing Kovar

Request a QuoteFrequently Asked Questions
Does CNC Gear Hobbing Kovar require dedicated tooling?
Most Kovar gear cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What gear accuracy class can you achieve on Kovar?
Gear accuracy is specified to DIN/AGMA classes appropriate to the application. Profile and lead are controlled so Kovar gears run accurately and quietly under load.
How clean are the edges produced by CNC Gear Hobbing on Kovar?
Machined Kovar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on Kovar with CNC Gear Hobbing?
Surface finish on Kovar is controlled to your specification; we confirm the achievable Ra against your callout.
