CNC Centerless Grinding Nickel from VT machining delivers precision Nickel parts produced to your exact drawing. Centerless grinding supports the workpiece on a blade between wheels for high-throughput OD finishing, and we tune every parameter to the behaviour of Nickel, which is corrosion and heat resistant.

Gummy and work-hardening at once. Sharp tools, positive rake, and a deliberate depth of cut that stays under the hardened skin from the previous pass.
How CNC Centerless Grinding Nickel Works
An abrasive wheel removes a fine, controlled layer from the Nickel part. Wheel specification, dressing interval, infeed and coolant are matched to the alloy's hardness so the surface is not burned or left with residual stress.
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 Centerless Grinding Nickel
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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.
Secondary Operations & Finishing
Most Nickel 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 Centerless Grinding Nickel
Small design adjustments often cut cost and lead time. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on Nickel efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Nickel
Nickel is corrosion and heat resistant. 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.
CNC Centerless Grinding Tolerances & Surface Finish
Ground Nickel reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
CNC Centerless Grinding 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.
Applications of CNC Centerless Grinding Nickel
Nickel 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 Centerless Grinding Nickel
Starting your project takes one email. Send your CAD or 2D drawing, the Nickel 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.
Parts We Have Run in Nickel
Three representative CNC Centerless Grinding Nickel jobs, with the callouts that actually drove the process plan. Yours will differ — these are here so you can judge whether your part is in our range before you spend time on an RFQ.
Punch tool
- Material
- Nickel
- Size
- Ø10 × 60 mm
- Key callouts
- OD ±0.002 mm, roundness 0.002 mm, Ra 0.1 µm
- Batch
- 300 pcs
Cylindrical ground after hardening to 60 HRC — machining soft would not hold the size.
Lapping plate

- Size
- 300 × 300 × 30 mm
- Key callouts
- Flatness 0.005 mm over the full face
- Batch

Ground, stress-relieved, ground again — one pass will not hold flatness on this area.
Slitter blade
- Material
- Nickel
- Size
- Ø150 × 1.5 mm
- Key callouts
- Thickness ±0.005 mm, edge concentricity 0.005 mm

Ground in a stack so all blades in a set share the same thickness.
Finishing Options for Nickel
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Centerless Grinding Nickel
- 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 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 Nickel a good choice for CNC Centerless Grinding?
Nickel is corrosion and heat resistant, which makes it well suited to CNC Centerless Grinding. We tune the process to the alloy so the finished Nickel grinding part meets your dimensional and functional requirements.
What material thickness or size range suits CNC Centerless Grinding Nickel?
We machine Nickel across a broad size range; share your part envelope for confirmation.
Does CNC Centerless Grinding Nickel require dedicated tooling?
Most Nickel grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
How clean are the edges produced by CNC Centerless Grinding on Nickel?
Machined Nickel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
