Mecvona machines custom parts to your drawings — CNC milling, turning, Swiss and multi-axis work, finished and inspected in house. Send a drawing and an engineer reviews it before you receive a quote.
CNC machining removes material from a solid block or bar with computer-controlled cutting tools, holding the dimensions and surface finish your drawing calls out. It suits parts where tolerance, repeatability and material choice matter more than tooling cost — which covers most precision components in regulated industries.
Mecvona runs milling, turning, Swiss and multi-axis machines across a verified manufacturing network, supported by grinding, finishing and in-house inspection. That range means a part with turned features, milled faces and a tight-tolerance bore moves through fewer setups and fewer suppliers — so dimensions stay aligned and you have one point of contact from quote to delivery.
Every quote starts with an engineer reading your drawing. We flag features that will be hard to hold, suggest changes that cut cost without touching function, and confirm the process before any metal is cut. You get a part that matches the print, not a surprise at first-article inspection.
Process selection is the first cost decision on any machined part. We route each drawing to the machine that holds its tolerances in the fewest setups, because setups are where both money and accuracy leak.
A straightforward path built around engineering review, not a black-box quote.
Upload a 3D model and 2D drawing, or a sample.
We review features, tolerances and material.
Price, lead time and process plan confirmed.
First article machined and inspected.
Batch or volume run on approval.
Report and certs sent with the parts.
The drawing tells us which dimensions are critical, what tolerances apply and which finish you need — the details that decide how a part is made and what it costs.
We machine a focused range of metals and engineering plastics chosen for precision parts. Need a grade that isn’t listed? Ask — most can be sourced.
Corrosion resistance and strength for semiconductor, medical and fluid components.
Light, easy to machine and anodize. Common for housings, brackets and heat sinks.
High machinability and conductivity for connectors, terminals and contacts.
Strength-to-weight and biocompatibility for aerospace and medical parts.
Heat-treatable steels for shafts, gears and wear-resistant components.
High-temperature strength and corrosion resistance for demanding service.
Stiff, low friction and dimensionally stable. The easiest engineering plastic to machine.
Tough and wear-resistant for gears, bushings and guides.
High temperature and chemical resistance. Biocompatible; can replace metal in some parts.
Chemical resistance and very low friction for seals, gaskets and insulators.
High impact strength and clarity for covers, guards and transparent parts.
Specialty and general-purpose plastics for electrical, structural and prototype use.
Full grade list and properties on the materials library. Material certificates supplied on request.
Parts ship as-machined by default, or with any of the treatments below applied to spec.
Standard finish, deburred with edges broken. Ra 3.2 µm typical.
Uniform matte texture that removes tool marks.
Corrosion and wear resistance on aluminum, with colour options.
Smooths and brightens stainless; lowers surface roughness.
Restores the corrosion-resistant layer on stainless steel.
Directional satin texture for a cleaner cosmetic surface.
Conversion coating on steel for corrosion and glare control.
Durable coloured coating for metal parts.
Nickel, zinc, tin and similar for wear, corrosion or conductivity.
Hardening and tempering to reach target strength.
Stepped polishing to a smooth, reflective surface.
Permanent part numbers, logos and traceability marks.
Standard capability below. Tighter tolerances are confirmed per feature during engineering review.
| SPECIFICATION | CAPABILITY |
|---|---|
| Dimensions without tolerance callouts | Machined to ISO 2768-m (metals and plastics) |
| Toleranced features, per drawing | Down to ±0.005 mm on turned and milled features |
| Ground / honed features | Down to ±0.002 mm, post-heat-treat |
| GD&T (position, runout, flatness...) | Per drawing callout · verified on CMM, reported on request |
| Threads | Metric coarse/fine, UNC/UNF · checked with go/no-go gauges |
| Surface finish, as machined | Ra 1.6 µm standard · Ra 0.8 µm fine machining |
| Surface finish, ground or honed | To Ra 0.2 µm |
| Smallest machinable feature | 0.5 mm nominal, geometry dependent |
| Milling envelope | Up to 800 × 500 × 400 mm |
| Turning envelope | Up to Ø200 × 500 mm |
| Swiss-type bar capacity | Ø1 – 32 mm |
If your part sits outside these ranges, send the drawing anyway. Capability depends on geometry as much as size — a table can’t tell you whether a thin-walled Ø220 housing is machinable, but an engineer looking at the model can, usually within a day.
Inspected, Documented, Repeatable
Critical dimensions and GD&T are agreed up front, not discovered late.
Parts are measured through the run, not only at the end.
Ship with every order. PPAP and custom reporting on request.
Swiss and precision turning down to ±0.005 mm, backed by grinding and CMM verification — not estimated, measured.
Milling, turning, Swiss, turn-mill, 5-axis and finishing in one network, so multi-feature parts don't bounce between shops.
A person who understands machining reads your drawing and gives real DFM feedback before you commit.
AS9100D and IATF 16949 systems, with inspection records and certs that hold up to audits.
Drawings stay confidential and we sign an NDA on request before reviewing sensitive designs.
Parts ship worldwide with export documentation and packaging that protects critical surfaces in transit.
General tolerances follow ISO 2768-m as standard. Tighter tolerances down to ±0.005 mm are available on suitable features, materials and processes, confirmed during engineering review before quoting.
No rigid minimum for most parts. We quote from a single piece up to volume production and optimise pricing to the quantity you need.
Both. Metals include stainless, aluminum, brass, copper, titanium, Inconel and alloy steels; plastics include POM, nylon, PEEK, PTFE, PC and PEI. Other grades can usually be sourced on request.
As-machined, bead blasting, anodizing (Type II and III), electropolishing, passivation, brushing, black oxide, powder coating, plating and heat treatment. Parts ship as-machined unless you specify otherwise.
A 3D model in STEP, IGES or X_T, plus a 2D drawing (PDF or DWG) showing critical dimensions, tolerances, GD&T, material and surface finish. The drawing tells us which features are critical.
Both. We run single prototypes and first articles through to ongoing production, with the same inspection and documentation at each stage.
Drawings and models are treated as confidential and we sign an NDA on request before reviewing sensitive designs.
Lead time depends on geometry, material, finish and quantity. Prototypes are typically ready in days and production runs in a few weeks. A firm date is confirmed with each quote.
Upload your model and drawing with material, quantity and tolerance. An engineer reviews your part and responds within one business day with pricing, lead time and any DFM feedback.
