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 Cylindrical 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.
At VT machining the process runs under full CNC control on calibrated equipment. In practice, that means this: Cylindrical grinding finishes outer diameters of rotational parts to precise size and roundness. If you do not have a CAD file yet, the free 3D + 2D builder on this page will produce a drawing we can quote from.
How CNC Cylindrical 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.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.

Inspection & dispatch
In-process checks plus final inspection, with CMM reports, mill certs and FAIR on request.
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.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.

CNC Cylindrical Grinding by Metal — Choose Your Material
Select the alloy you are working in to see material-specific capability, design guidance and applications.
A few design choices make a real difference to cost and quality. 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
We complete metal components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
CNC Cylindrical Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on metal parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.

What material thickness or size range suits CNC Cylindrical Grinding?
We machine the material across a broad size range; share your part envelope for confirmation.
Does CNC Cylindrical Grinding require dedicated tooling?
Most CNC Cylindrical Grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What tolerances can you hold for CNC Cylindrical Grinding?
Achievable tolerances for CNC Cylindrical Grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.
