Makino is the originator of high-speed spindles for commercial use. With spindles able to achieve speeds of 20,000 rpm and above, it’s no wonder we are the undisputed leader in high-speed high-efficiency machining center technology. Makino machines will deliver precise statistical performance and dramatically reduced cycle times.
The a92 horizontal machining center is designed for machining large structural components, made of tough-to-cut materials, for trucks, construction equipment, agricultural machinery, aircraft and other products. Its X-axis travel of 1,520 mm is ideal for machining the cylinder blocks of in-line 6-cylinder engines. The standard spindle produces powerful output of 45 kW, enabling the a92 to execute a wide range of machining jobs.
Dual ball screws and twin servomotors in the Z-axis
The Z-axis feed mechanism for moving the table longitudinally adopts dual ball screws and twin servomotors, enabling high-speed movement of large workpieces weighing up to 3,000 kg (optional specification).

Control unit that maximizes machine performance
Professional 6 optimizes machine motion, according to machining conditions. Even in machining with high-speed and high-acceleration, machining surface quality and shape accuracy can be kept. Machining efficiency is totally enhanced. A variety of machining modes are preset. Operator can easily choose suitable one for its purpose.
Advanced control technology (for reducing non-cutting time)
The four following features indispensable to reliable chip
removal are all standard on the a92.
-8-nozzle coolant supply device
-Overhead shower coolant system
-Center chip trough
