For maintenance
When the line stops, you don't wait for the machine builder.
We make the spare part for your special-purpose machine or line – to drawing, from a 3D model or just from the worn piece. We keep your critical parts in stock so you don't wait at all.
How it works
From a broken part to a replacement in days
Send what you have
A drawing, STEP, a photo or the part itself. One e-mail to Vít Volný – you know within the day whether and when.
We measure and model
The worn or broken part is measured with 3D probes (down to 2 µm); we add tolerances by function and suggest a better material or heat treatment.
We make it complete
Machining, hardening, grinding, wire EDM and surface finishing under one roof. Regular partners get priority.
Delivered with documentation
The part comes with an inspection protocol, drawing and 3D model. The next order is just a part number in an e-mail.
What to send us
The more you have, the faster the quotation. But a single item from the list is enough.
- Drawing (PDF) or 3D model (STEP) – if it exists
- A photo of the part in the machine and what it does
- The worn or broken piece – we collect it or you ship it
- Material and hardness, if known
- Quantity and deadline – and whether it is a part you replace regularly
Typical maintenance parts
Consignment stock: the part is ready before you need it
We manufacture critical parts in advance and keep them in our or your warehouse. You draw and pay only when the part is actually used. The documentation stays with us, so the next piece is made without questions.
What downtime costs
An hour of a stopped line costs more than the part

We can keep your critical parts in consignment stock and we manufacture urgently for regular partners. Every hour saved is pure profit.
Free and without obligation
Critical-parts audit
Send us a list of the 10 parts that most often stop your production (a photo or drawing of each is enough). We return a proposal of what to keep in consignment stock, in what quantity and at what price. It saves weeks of downtime a year.
Send the parts list for an auditThe builder of our machine no longer exists or does not supply the part. Can you help?
Yes, that is our most common case. We measure, model and manufacture the part; you receive a drawing and 3D model, so next time you just order a part number.
How fast can you deliver a part for a stopped line?
Regular partners are served with priority – simple rotational parts typically within 2–5 working days, complex ones within 2 weeks. Critical parts are better kept in consignment stock.
Can you improve the part so it lasts longer?
Often yes – a different material, hardening, coating or a geometry change. We propose it in the quotation and you decide.
Do you also make series parts for production?
No. We focus on one-off and small-batch work of 1–99 pieces for maintenance and development, where precision, lead time and reliability matter.
No-obligation enquiry
Send us the part that troubles you
Vít Volný will tell you by the next day whether, when and for how much. No form – an e-mail with a photo or drawing is enough.
