CNC Grinding is a core in-house capability at VT machining, supported by full inspection and a single engineering contact from quote to delivery.
CNC grinding removes material with a precision abrasive wheel to achieve tight dimensional tolerances and superior surface finish. Because the same engineers handle quoting, programming and inspection, nothing is lost between your drawing and the finished part.

FREQUENTLY ASKED QUESTIONSWhich grinding processes are available?
Surface, cylindrical, centerless and thread grinding plus honing. The builder captures surface finish Ra, flatness and parallelism so the right process is selected at engineering review.
What finish and flatness can grinding achieve?
Surface finishes from Ra 0.8 down to mirror (below Ra 0.05), with flatness and parallelism to 0.002 mm on stable parts — single-digit micron capability on ground faces.
CNC Grinding is an abrasive finishing process. A bonded wheel removes a very fine layer of material, which is how single-micron size control, tight flatness or roundness, and mirror-class surface finishes are achieved — including on hardened parts that cannot be cut with conventional tooling.
VT machining runs CNC Grinding in-house, so scheduling, quality and revisions stay under one roof. CNC grinding removes material with a precision abrasive wheel to achieve tight dimensional tolerances and superior surface finish — 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 Grinding Works at VT machining
An abrasive wheel removes a fine, controlled layer from the metal 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.
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 Grinding Tolerances & Surface Finish
Ground metal 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.
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 Grinding 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. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on metal efficiently. 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 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.

Which industries use CNC Grinding parts?
CNC Grinding parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise components are required.
What surface finish is achievable on with CNC Grinding?
Grinding can take the part to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
Does CNC Grinding require dedicated tooling?
Most CNC Grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
