 The majority of global aviation players are looking to the Middle East as the next area of growth in the industry. The rapidly growing use of titanium in aerospace and other applications has focused industry attention on the need for improved processing capabilities for this difficult-to-machine material.
Makino offers the new T2 5-axis horizontal machining centre with ADVANTiGE technology designed for mid-sized titanium aerospace part production. Its purpose-built design provides the rigidity, dynamic stiffness, vibration damping and agility necessary for more productive titanium machining and longer tool life.
"Makino's ongoing titanium research and development continues to offer the most effective process solutions for a wide variety of today's aerospace structural and engine components," says Mark Larson, Makino's Titanium Process R&D Manager. "Our latest solution, the T2 with ADVANTiGE technology, is like no other titanium machining centre on the market today. Specifically designed from the ground up for high-efficiency titanium part production, it effectively reduces hazardous vibration and thermal conditions traditionally associated with titanium machining."
The T2 provides X-, Y- and Z-axis travels of 2,000mm, 2,000mm and 1,800mm, respectively, allowing for part sizes up to 1900mm by 2000mm and 5,000kg. The T2's construction features large way surfaces and table casting for extra rigidity and vibration damping, as well as a 120-position automatic tool changer (up to 190 available) for continuous, uninterrupted machining.
Rigid, high-power spindle
The T2's HSK-A125 spindle is Makino's most powerful spindle to date, delivering higher torque, horsepower and clamping force than all predecessors. Its compact design combines the latest induction motor with twin-inverter-drive technology for higher torque (740ft-lbs, 133HP continuous; 1,100ft-lbs, 200HP peak). The spindle is supported by roller bearings to ensure high rigidity, which keeps the energy loss to one-half that of conventional gear-driven spindles. The spindle delivers a maximum speed of 4,000 rpm. The A- and C-axes increase part accessibility with a ±110- degree A-axis rotation and a 360-degree continuous C-axis rotation.

Unattended machining capabilities
The T2 includes an automatic pallet changer system that features continuous operation and eliminates costly downtime for part changeovers with pallet change times of only 60 seconds.
This machine can also be integrated with an automatic pallet transfer and storage system in a highly flexible Makino Machining Complex (MMC) for extended periods of unattended operation. This automation system assigns work and initiates operations automatically, maximising spindle utilisation for increased productivity.
The national regulator, Bahrain Civil Aviation Affairs, works to globally-respected aviation standards. However, completing the registration of this aircraft in an extremely short period of time during February of this year, demonstrates the sheer professionalism and positive attitude that Bahrain CAA continues to show to the aviation community in Bahrain, regionally and globally.

MENA aerospace
MENA Aerospace Enterprises' airline division, MAE Aircraft Management, completed the induction and registration of a Boeing 737-300F under its Bahrain Aircraft Operating Certificate. This is the third aircraft that MAE Aircraft Management is operating in its fleet with the intent of increasing the number of aircraft over the next couple of years to double that figure.
The MAE Aircraft Management team worked tirelessly alongside Bahrain CAA to add airline and cargo capabilities to its existing Aircraft Operating Certificate. This achievement represents a significant expansion of the operational capabilAir Jordan 1
