CNC machining

CNC machining of metal parts

We machine parts on our CNC machining centre to hold tolerances, prepare seats and finish functional surfaces on demanding metal components.

What the service involves

Machining comes in when the accuracy of cutting and forming is not enough. Some dimensions have to hold tight tolerances, some surfaces have to be flat and smooth for another component to sit on, and some seats have to take a bearing, a shaft or a bolt with a specific fit.

The CNC machining centre works from the program prepared by our engineering office and carries out these operations on the part, holding the same dimension across the whole batch.

At Catà Germans machining is used mainly as a functional finishing process within jobs that start in sheet or tube, rather than as a standalone service: it is what lets us deliver a complete part instead of one that still needs another workshop.

Materials we work with

Materials and thicknesses we work with as standard. If your project needs a material that is not listed, say so in your enquiry and we will confirm whether we can handle it.

This service works with the same materials and thicknesses as the rest of the plant. The full table is on the Sheet metal laser cutting page.

Parts and applications

  • Seats for bearings, shafts and fixing elements.
  • Faced bearing surfaces within an assembly.
  • Correcting critical dimensions on cut or welded parts.
  • Functional finishing of parts that are then assembled.
  • Precision operations on already-welded assemblies.

Why work with Catà Germans

Every process under one roof
Cutting, forming, machining, welding and finishing in the same plant. The part does not travel between workshops, which cuts lead times and points of failure.
In-house engineering office
We review the drawing before manufacturing and prepare production from CAD/CAM. If something does not add up, we ask you instead of interpreting it ourselves.
Raw material in stock
We keep sheet and tube permanently in stock, so many standard jobs can start without waiting for material.
Over 65 years of the trade
A family business founded in 1958, specialised in industrial subcontracting of metal parts. You deal directly with the people who make the part.

Frequently asked questions

Do you offer machining as a standalone service?

Machining is usually part of a wider job that begins in sheet or tube. If you need machining only, on your own parts, send us the drawing and we will assess whether we can take it on.

What tolerances can you hold?

It depends on the part, the material and the machine assigned. Mark the critical dimensions and their tolerances on the drawing and we will confirm feasibility with the quote.

Can you machine a part that has already been welded?

Yes. It is a common sequence: weld the assembly first, then machine the dimensions that must end up exact once welding distortion is out of the way.

Which file formats do you accept?

We accept PDF, DXF, DWG, STEP/STP, STL, IGS/IGES and also PNG or JPG images. If you do not have a final drawing yet, send us a dimensioned sketch and we will review it all the same.

Do you make one-off parts or only production runs?

We handle one-off parts and prototypes as well as small, medium and large batches and repeat production. You can specify this in the quote request.

How quickly do you reply to an enquiry?

We send a technical response in under 48 hours from receiving the drawing and the part details.

Can several processes be combined on the same part?

Yes — that is the normal way we work. A part can go through laser cutting, bending, welding and finishing inside the same plant, under a single order and a single point of contact.
