Two phases with very different behaviour in one part. EDM gives a far more consistent result than milling on fine features, and it is the usual route for heat-spreader profiles.
How CNC Gear Hobbing Tungsten Copper Works
Tooth profiles are generated in the Tungsten Copper 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.
Achievable Tolerances for CNC Gear Hobbing Tungsten Copper
| Feature | Standard | Precision |
|---|---|---|
| Accuracy class | DIN 8 / AGMA 10 | DIN 6 / AGMA 12 |
| Profile deviation | 0.020 mm | 0.008 mm |
| Lead deviation | 0.020 mm | 0.008 mm |
| Pitch deviation (cumulative) | 0.040 mm | 0.015 mm |
| Runout | 0.030 mm | 0.010 mm |
| Tooth surface finish | Ra 1.6 µm | Ra 0.4 µm (ground) |
| Module range | m0.5–m8 | m1–m6 |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
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.
Working with Tungsten Copper
Tungsten Copper is combines tungsten strength with copper conductivity. 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 Tungsten Copper 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 Tungsten Copper
Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Tungsten Copper gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
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 Tungsten Copper
Tungsten Copper 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 Tungsten Copper
Starting your project takes one email. Send your CAD or 2D drawing, the Tungsten Copper 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 We Need to Quote CNC Gear Hobbing Tungsten Copper
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact Tungsten Copper grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

Request a QuoteFrequently Asked Questions
Why is Tungsten Copper a good choice for CNC Gear Hobbing?
Tungsten Copper is combines tungsten strength with copper conductivity, which makes it well suited to CNC Gear Hobbing. We tune the process to the alloy so the finished Tungsten Copper gear cutting part meets your dimensional and functional requirements.
What surface finish is achievable on Tungsten Copper with CNC Gear Hobbing?
Surface finish on Tungsten Copper is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Gear Hobbing Tungsten Copper require dedicated tooling?
Most Tungsten Copper 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 Tungsten Copper?
Gear accuracy is specified to DIN/AGMA classes appropriate to the application. Profile and lead are controlled so Tungsten Copper gears run accurately and quietly under load.
