Looking for reliable CNC Gear Grinding Brass? VT machining manufactures Brass parts to tight tolerances and consistent quality. Brass is free-machining, good conductivity, attractive finish, so the process is set up specifically for the material.

- Low transmission noise
Brass material properties, finishing options and grade notes are on our CNC Gear Hobbing Brass page.
How CNC Gear Grinding Brass Works
Tooth profiles are generated in the Brass 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 Grinding Brass
| 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.
Design Tips for CNC Gear Grinding Brass
Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Brass gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Gear Grinding 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 Grinding Brass
Brass parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
Typical Brass Parts for CNC Gear Grinding
Illustrative examples of CNC Gear Grinding Brass 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.
Internal ring gear
- Material
- Brass
- 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.
Worm and wheel set
- Material
- Brass
- 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.
Helical pinion
- Material
- Brass
- Size
- m1.5, z18, 15° helix
- Key callouts
- DIN 6, lead deviation 0.008 mm
- Batch
- 300 pcs
Ground after case hardening to 58 HRC at 0.6 mm case depth.

What We Need to Quote CNC Gear Grinding Brass
- 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 Brass 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
Does CNC Gear Grinding Brass require dedicated tooling?
Most Brass gear cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Can VT machining make custom Brass parts to my drawing?
Yes. Brass gear cutting is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What surface finish is achievable on Brass with CNC Gear Grinding?
Surface finish on Brass is controlled to your specification; we confirm the achievable Ra against your callout.
Which industries use CNC Gear Grinding Brass parts?
CNC Gear Grinding Brass parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Brass components are required.
