Large parts
Beds, frames, beams and structures from 1 to 8 metres in a single set-up. Beyond that size, we work in several set-ups.
Machining workshop · Porqueres (Girona) · since 1951
Beds, beams and structures up to 8 metres long in a single set-up, accurate to hundredths of a millimetre. To drawing or from a sample.
Capacity
Our gantry and fixed-bed machines are built for large, heavy parts. Here they are drawn to real scale, next to a person.
Longer parts in several set-ups: we have milled 10-metre beams. Weight is no limit, with overhead cranes of up to 20 t.
What we do

Beds, frames, beams and structures from 1 to 8 metres in a single set-up. Beyond that size, we work in several set-ups.

CNC centres with swivel heads and a Ø 130 mm bar boring machine. We have bored housings of up to Ø 1200 mm.

Three automated gantry milling machines to leave large surfaces flat and at exactly the thickness you need.

Send us the drawing, the 3D model or the part, and our CAD-CAM department works out how to make it.
Work
How we work
Drawing, 3D model or physical sample. We adapt to whatever format you have.
We choose the machine and the set-up strategy, and give you a free, no-obligation quote.
CAD-CAM programming and machining on the centre best suited to the size and tolerance.
Dimensional inspection before the part leaves the workshop.
We work for companies in printing, food, industry and textiles, many of them leaders in their field.
