CNC Gear Hobbing is a core in-house capability at VT machining, supported by full inspection and a single engineering contact from quote to delivery.
Gear hobbing generates gear teeth with a rotating hob synchronized to the workpiece. Because the same engineers handle quoting, programming and inspection, nothing is lost between your drawing and the finished part.

Custom CNC Machining BuilderConfigure any custom precision machined metal part not covered by the other process builders: choose metal, shape, size, thickness, optional holes and finishing, then add notes or attach a drawing at RFQ. Every builder includes the Freeform Corner & Region Editor: cut or add material of any shape directly on the 3D model, then submit an RFQ.This tool is for visual configuration only. Final dimensions, tolerances, materials, coatings, and manufacturability will be reviewed from your drawing or specification.
Paste a configuration JSON (from Export) or a copied RFQ summary. The product and all recognized parameters are applied automatically; unknown parameters are listed and skipped.
Answer the choices below step by step — every value comes from the real option list, so it always renders.
Save the current configuration under a name and recall it any time on this device.

FREQUENTLY ASKED QUESTIONSWhat if my part does not match any standard process builder?
Use the Custom CNC Machining Builder: choose the metal, shape (including ring or drawing-defined outline), size, thickness, optional holes, slots and finishing, set a tolerance, preview it in 3D and attach a drawing to the RFQ. Our engineers pick the best process route.
Which metals can the custom builder use?
Aluminum, stainless and carbon steels, tool steels, brass, copper, titanium, tungsten, molybdenum, Invar/Kovar and nickel alloys, or a named custom alloy such as Inconel 718 or Hastelloy.
CNC Gear Hobbing generates or finishes gear tooth geometry to a defined accuracy class. Module, pressure angle, helix and profile shift come straight from your gear data, and tooth form is verified so the gearset runs quietly and carries load as designed.
VT machining runs CNC Gear Hobbing in-house, so scheduling, quality and revisions stay under one roof. Gear hobbing generates gear teeth with a rotating hob synchronized to the workpiece — and the parameters are set from your material and geometry, not a default recipe. Send a CAD model or a 2D print and we will confirm feasibility, tolerances and lead time before you commit.
How CNC Gear Hobbing Works at VT machining
Tooth profiles are generated in the metal blank by a synchronised cutter, then refined to the required accuracy class. Module, pressure angle and helix are programmed from your gear data.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.

Inspection & dispatch
In-process checks plus final inspection, with CMM reports, mill certs and FAIR on request.
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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.

CNC Gear Hobbing by Metal — Choose Your Material
Choose a metal below for grade-level detail, achievable tolerances and typical parts in that material.
Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce metal 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 metal 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.
