What is long part machining?
Long part machining is a technical process for producing parts by removing material. In our case, we produce parts by large part milling or by boring.
Long part machining technology delivers high precision on very large parts: on parts up to 12.5 metres long, we can achieve a precision of up to 2 hundredths of a millimetre. This enables us to meet the varied needs of customers from every industry sector, internationally: automotive, aerospace, defence…
We machine parts up to 12.5 metres long and 2 metres wide.
Large part machining and welded fabrication
We offer our customers both large part machining and welded fabrication services.
We are one of the few companies in the industry able to deliver welded and machined parts to our customers.
