CNC Gear Cutting Tungsten

VT machining provides CNC Gear Cutting Tungsten for customers who need accurate, repeatable Tungsten components. Because Tungsten is extreme hardness, density and heat resistance, we adapt the process to suit — controlling the variables that matter for this alloy.

How CNC Gear Cutting Tungsten Works

Tooth profiles are generated in the Tungsten 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.

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 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.

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.

Design Tips for CNC Gear Cutting Tungsten

Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Tungsten gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.

Applications of CNC Gear Cutting Tungsten

Tungsten parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

Typical Tungsten Parts for CNC Gear Cutting

Illustrative examples of CNC Gear Cutting Tungsten parts and the callouts that usually drive the process plan. They show the kind of work that fits this process; they are not specific customer orders.

Worm and wheel set

Material
Tungsten
Size
m3, single start
Key callouts
Backlash 0.05–0.10 mm as a matched pair
Batch
120 sets

Supplied as matched sets and marked, because mixing pairs loses the backlash spec.

Internal ring gear

Material
Tungsten
Size
m2.5, z72, ID 190 mm
Key callouts
DIN 8, pitch deviation 0.03 mm
Batch
150 pcs

Shaped rather than hobbed — an internal gear leaves no room for a hob to run out.

Bevel gear pair

Material
Tungsten
Size
m2, z20/z40, 90° axes
Key callouts
DIN 8, mounting distance ±0.03 mm

What We Need to Quote CNC Gear Cutting Tungsten

  • 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 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.

Frequently Asked Questions

What surface finish is achievable on Tungsten with CNC Gear Cutting?

Surface finish on Tungsten is controlled to your specification; we confirm the achievable Ra against your callout.

What material thickness or size range suits CNC Gear Cutting Tungsten?

We machine Tungsten across a broad size range; share your part envelope for confirmation.

Why is Tungsten a good choice for CNC Gear Cutting?

Tungsten is extreme hardness, density and heat resistance, which makes it well suited to CNC Gear Cutting. We tune the process to the alloy so the finished Tungsten gear cutting part meets your dimensional and functional requirements.

What is the typical lead time and minimum order for CNC Gear Cutting Tungsten?

CNC Gear Cutting prototypes for Tungsten can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
