About us

CMI Aeronáutica S.L. was founded in Seville in 1993 as a family-run company specialising in aeronautical maintenance. By 1997, there was a growing demand for the manufacture and maintenance of machine tools and so, taking advantage of its extensive knowledge of “DYE” technology and the sector for over 80 years, , the company decided to move to its current location in the Duranguesado valley.


Once established in Durango, the company began with 6 workers primarily dedicated to machine maintenance. Today, the company has a great team of people who undertake ongoing training to ensure their skills are up to date and work with motivation and commitment to assume the challenge of providing the technical solution that best suits a customer’s specific needs by applying the latest technologies available.

To enable this, the company offers a range of products with specific characteristics which are highly valued and established in different sectors (Aeronautics, Automotive, Railways, Marine, Wind energy, Manufacture of casting patterns, Capital Assets, Aerospace, etc…) and it also offers tailor-made products which are practically à la carte and give excellent value for money in those cases where the customer requires a special technical solution.


Its main manufactured product lines are CNC milling machines and Special Vertical Lathes , both new machines and retrofitting of old machines, together with Engineering, Repair and Preventive Maintenance services for Machine Tools. In addition, it has its own resources in its facilities for the machining of large parts.


All the products made are distinguished by their high added value, both in terms of technology and in quality and service.
