This Correa AXIA-70 is a used milling machine — sometimes referred to as a machining centre — designed for precision material removal across metal workpieces, particularly in heavy-duty industrial and aerospace manufacturing contexts. Correa is a Spanish manufacturer with a long-standing reputation for building large-format, high-precision milling machines and machining centres, serving industries such as aerospace, energy, automotive tooling, and general engineering.
The machine is a mobile column configuration, and its axis travels reflect its capacity for large-scale work: 7,000 mm in X, 1,250 mm in Y, and 1,500 mm in Z, making it well suited to machining extensive or complex structural components. The spindle accepts ISO 50 tooling and reaches a maximum speed of 6,000 rpm, with a spindle motor rated at 37 kW — a combination appropriate for both heavy roughing and controlled finishing operations. The machine weighs 40,000 kg and has an overall footprint of 11,900 × 5,170 mm with a height of 4,225 mm, underscoring the scale of the platform.
Control is provided by a Heidenhain iTNC 530, a widely used conversational CNC system known for its capability in complex multi-axis contouring. The head is an automatic UAD unit with 0.02° × 0.02° indexing resolution, enabling precise angular positioning for five-axis-style operations without manual intervention. Tool changes are handled by an integrated automatic tool changer with a capacity of 60 tools, supporting long unattended machining cycles. Operator intervention during setup is assisted by a Heidenhain HR-410 electronic handwheel.
Additional equipment fitted to this machine includes an internal high-pressure coolant system operating at 30 bar, which assists chip evacuation and thermal management at the cutting zone, an electrically cooled control cabinet to maintain stable operating temperatures in the electrical panel, and a chip conveyor for continuous swarf removal during production. The machine is located in Spain.
