CNC Bending Molybdenum from VT machining delivers precision Molybdenum parts produced to your exact drawing. CNC bending forms sheet metal to precise angles using a programmed press brake and back-gauge, and we tune every parameter to the behaviour of Molybdenum, which is very high melting point and thermal stability.

Published typical values for Pure Mo / TZM. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Below its ductile-to-brittle transition it chips rather than cuts. Sharp corners get a radius, and thin sections are wire-EDM cut instead of milled.
How CNC Bending Molybdenum Works
The Molybdenum blank is bent or formed against tooling under CNC-controlled ram travel and back-gauge positioning. Bend allowance and springback are compensated in the program so finished angles hit the print.
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.
Achievable Tolerances for CNC Bending Molybdenum
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
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
We complete Molybdenum 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 Bending Tolerances & Surface Finish
Formed Molybdenum holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
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.
Design Tips for CNC Bending Molybdenum
A few design choices make a real difference to cost and quality. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed Molybdenum. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Bending Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Molybdenum 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.
Working with Molybdenum
Molybdenum offers a useful combination of properties: it is very high melting point and thermal stability. Those characteristics shape how we approach forming — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
Applications of CNC Bending Molybdenum
CNC Bending of Molybdenum supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
How to Order CNC Bending Molybdenum
Ordering Molybdenum parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.

What We Need to Quote CNC Bending Molybdenum
- 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 Molybdenum 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.
