Frequently asked questions

If you cannot find an answer to your question here, please feel free to contact us directly. We’ll be glad to help you!

What services do you offer?

Our services include 3+1 axis CNC milling, 3D surface machining, 2 axis CNC turning, drilling, reaming, tapping, thread milling and more.

Although we can work with other materials upon request, we specialize in machining non-ferrous metals (mostly 6000 and 7000 series aluminium alloys) and engineering plastics (POM-C, UHMW-PE, PEEK, etc.).

More details can be found on our Services page.

What are your size capabilities?

We can produce parts with a size ranging from roughly a €1 coin up to:

  • For milled parts - 300x220x150mm;
  • For turned parts - ⌀70x120mm.

What tolerances can you achieve?

General tolerances: by default, we offer 3 different general tolerance levels (±0.10mm, ± 0.07mm, ±0.05mm). If you prefer, you can also specify the general part tolerances using the ISO 2768 standard.

Tight tolerances: we are capable of holding tight tolerances where you require them (a 2D drawing is need). Sometimes when a part is more complex, it can add some lead time to the order. We will still get it out in a timely fashion.

Can you thread/ream/bore holes?

Yes. If there are threaded or reamed holes in your part, please indicate it your quote request and include a 2D drawing with details.

What file types do you accept?

We accept .STEP, .STP, .DWF, .DWG, and .PDF files.

Where do you ship to?

We ship to countries within the European Union.

Where are you located?

Our facilities are located close to Lisbon, Portugal. If you would like to send us a postcard, you can find our address here. Please note that our facilites are not open to the public.

What payment methods do you accept?

We accept Paypal payments and SEPA bank transfers. You may find our payment details on the body of the quote you will receive. For a secure and fast transaction, Credit Card payments are only accepted through the Paypal platform.

How come I haven’t heard of you before?

The short answer is: we don’t advertise.

You have probably never heard of us before for a good reason. Almost all of our customers have come through word of mouth or organic search results (Google, DuckDuckGo, etc.). We do not advertise. Instead we prefer to invest our resources (time and money) into improving our equipment, tools and processes to better serve you and your projects. In the long term, this works better than advertising and everyone wins.
