VT machining provides CNC Gear Grinding Nickel Silver for customers who need accurate, repeatable Nickel Silver components. Because Nickel Silver is corrosion resistant with a bright silver-white finish, we adapt the process to suit — controlling the variables that matter for this alloy.

How CNC Gear Grinding Nickel Silver Works
Tooth profiles are generated in the Nickel Silver 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.
Achievable Tolerances for CNC Gear Grinding Nickel Silver
| 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 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.
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.
Design Tips for CNC Gear Grinding Nickel Silver
A few design choices make a real difference to cost and quality. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Nickel Silver 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 Grinding Nickel Silver
CNC Gear Grinding of Nickel Silver supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
Typical Nickel Silver Parts for CNC Gear Grinding
Illustrative examples of CNC Gear Grinding Nickel Silver 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
- Nickel Silver
- 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
- Nickel Silver
- 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
- Nickel Silver
- Size
- m1.5, z18, 15° helix
- Key callouts
- DIN 6, lead deviation 0.008 mm
- Batch

What We Need to Quote CNC Gear Grinding Nickel Silver
- 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 Nickel Silver 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.
