We remake parts nobody manufactures any more.

The manufacturer is gone, the catalogue is out of print, the part number returns nothing. Send the worn part or a drawing — we will reproduce it on a CNC lathe.

Part reproduction

From a worn sample, a drawing or bare dimensions.

It usually starts with a part that broke. We measure it — diameters, lengths, threads, radii, material hardness — and reconstruct documentation that never existed or vanished together with the manufacturer. The documentation stays with us, so the next piece a year from now is just a phone call.

Where the original was a weak point of the design, we say so and suggest a different material or transition radius. Never quietly — the decision is yours, because you know the conditions the part works in.

How it works

Four steps from a broken part to a new one.

  1. 01

    A photo and a description

    Send a photo with a ruler next to the part and tell us what it works in.

  2. 02

    Measuring the sample

    We receive the part by post, measure it and reconstruct the drawing.

  3. 03

    Quote approval

    You get a price, a lead time and a material suggestion. Nothing moves without your go-ahead.

  4. 04

    Machining and sample return

    We send the new part back together with the old one.

Materials

What we turn.

Structural steels
S235, C45, 16MnCr5, 42CrMo4
Stainless steels
1.4301, 1.4404, 1.4571
Aluminium
PA6, PA38, EN AW-7075
Brass and bronze
CuZn39Pb3, CuSn12
Plastics
POM, PA6, PTFE, PEEK

We can buy the material or you can supply your own. For a single piece the latter usually works out cheaper.

Questions

Common doubts.

The part is broken in half — can it still be reproduced?

Usually yes. Two fragments give us most of the dimensions, and the missing ones can be worked out from the geometry of the seat the part worked in. Send both pieces and a photo of where it mounts.

Can you reproduce an imperial or non-standard thread?

Yes. Imperial, trapezoidal and non-standard pitches are turned the same way as metric ones — it is a matter of the program, not of special tooling.

What about parts for old machines and aircraft?

That is our daily work. The company grew out of reproducing parts for the CSS-13 aircraft, and the ready-made items are in the shop catalogue. We work the same way for agricultural machinery, machine tools and classic cars.

Do I get the sample back?

Always. The worn part returns together with the new one — it is often needed for comparison during assembly.

Wycena

You have a part that no longer exists anywhere.

Take a photo with a ruler next to it and tell us what it works in. That is enough to start.
