Promac SMX Series

The Promac SMX Series is a line of horizontal machining centers produced by Promac, a Spanish machine tool builder based in the Basque Country — Spain's industrial heartland and home to a concentrated cluster of precision machine tool manufacturers. The SMX Series is oriented toward aerospace structural component machining, a segment where Spanish machine tool builders have developed significant expertise serving the Airbus supply chain based in Toulouse and Spain's own aerospace manufacturing centers in Getafe and Seville.

Promac positions the SMX Series as a production-capable horizontal machining platform for medium-to-large aluminum and titanium aerospace structural parts. The Basque Country's machine tool ecosystem — sharing expertise with neighboring builders like Danobat, Soraluce, and Ibarmia — has given Spanish HMC builders a strong foundation in high-rigidity heavy-duty machining for structural aerospace applications. The SMX Series reflects this tradition with heavy-section casting construction, high-power spindle options, and large work envelopes suited to aerospace panel and structural bracket families.

The SMX Series targets the specific demands of Airbus structural part suppliers: large aluminum panels requiring long-travel profiling, thick titanium fittings requiring high-torque roughing, and complex machined housings requiring good chip management. The horizontal spindle orientation ensures coolant and chips evacuate naturally from large-pocket aluminum parts — a significant process benefit for aerospace structural machining where swarf redeposition causes surface defects and tool damage.

Promac machines are distributed primarily within Europe, with strongest market presence in Spain, France, Germany, and the broader EU aerospace supply chain. Promac's application engineering team provides process development support for aerospace structural machining customers, including programming assistance, fixturing concepts, and cutting parameter development for aerospace alloys.
