Over the years, the Mirage team has designed and manufactured many successful milling machines for a wide range of on-site machining applications. One recent project was a perfect fit for the Derby based UK design team. Here’s an overview of the development process.

Our customer, an offshore engineering operator approached Mirage to design and produce a portable milling machine capable of removing weld seams from plates welded onto offshore platforms. The machine needed to work within a compact working envelope and be easily located around the work piece.

Meeting the brief

For engineering service companies and their customers, ‘time is money,’ so developing a design which can be set up quickly and is easy to use would benefit to everyone.
