Looking for reliable CNC Gear Hobbing Invar? VT machining manufactures Invar parts to tight tolerances and consistent quality. Invar is ultra-low thermal expansion, so the process is set up specifically for the material.
CNC Gear Hobbing Capability for Invar
- Spur & helical gears
- Module range support
- Pre-grind accuracy
- High productivity
How CNC Gear Hobbing 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.
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.
Design Tips for CNC Gear Hobbing 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.
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.
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 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 Hobbing 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 surface finish is achievable on Invar with CNC Gear Hobbing?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
Why is Invar a good choice for CNC Gear Hobbing?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Gear Hobbing. We tune the process to the alloy so the finished Invar gear cutting part meets your dimensional and functional requirements.
How clean are the edges produced by CNC Gear Hobbing on Invar?
Machined Invar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Does CNC Gear Hobbing 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.
