CNC Waterjet Cutting Stainless Steel

CNC Waterjet Cutting Stainless Steel from VT machining delivers precision Stainless Steel parts produced to your exact drawing. Abrasive waterjet cutting erodes metal with a high-pressure abrasive stream, with no heat-affected zone, and we tune every parameter to the behaviour of Stainless Steel, which is corrosion resistant, strong, hygienic (304/316 grades).

How CNC Waterjet Cutting Stainless Steel Works

A focused fibre-laser beam melts and blows material from the Stainless Steel sheet along the programmed contour. Power, focal position, nozzle stand-off and assist-gas pressure are tuned to the alloy and thickness for a clean, square edge.

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.

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 Waterjet Cutting Stainless Steel

Small design adjustments often cut cost and lead time. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Waterjet Cutting Tolerances & Surface Finish

Laser-cut Stainless Steel holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.

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 Waterjet Cutting Stainless Steel

Stainless Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

Typical Stainless Steel Parts for CNC Waterjet Cutting

Illustrative examples of CNC Waterjet Cutting Stainless Steel 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.

Control panel face

Material
Stainless Steel
Size
400 × 300 × 1.5 mm
Key callouts
Cutout position ±0.10 mm, no dross on visible face
Batch
600 pcs

Cut with nitrogen so the edge takes powder coat without secondary grinding.

Bracket blank

Material
Stainless Steel
Size
250 × 120 × 4 mm
Key callouts
Contour ±0.10 mm, bend-relief notches
Batch
800 pcs

Bend reliefs cut in at the same time so the press brake does not tear the corner.

Battery busbar

Material
Stainless Steel
Size
180 × 30 × 2 mm
Key callouts
Contour ±0.08 mm, hole ±0.05 mm
Batch
2,000 pcs

Copper is cut on the fibre laser with a reflective-material head; not every shop can run it.

What We Need to Quote CNC Waterjet Cutting Stainless Steel

  • 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 Stainless Steel 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.

Frequently Asked Questions

Can VT machining make custom Stainless Steel parts to my drawing?

Yes. Stainless Steel 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 is the typical lead time and minimum order for CNC Waterjet Cutting Stainless Steel?

CNC Waterjet Cutting prototypes for Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.

What surface finish is achievable on Stainless Steel with CNC Waterjet Cutting?

Laser cutting leaves a clean cut face on Stainless Steel with a small heat-affected zone; most parts need little secondary finishing.

How clean are the edges produced by CNC Waterjet Cutting on Stainless Steel?

Laser cutting leaves Stainless Steel with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
