a120nx

Introduction

The a120nx horizontal machining center is most suitable for structural parts machining for large industrial machines such as automobile, energy, construction, agricultural and semiconductor manufacturing equipment. The standard spindle produces powerful output of 55 kW, enabling the a120nx to execute a wide range of machining jobs.


STRUCTURE

Dual ball screws and twin servomotors in the Y-axis and Z-axis
The Y-axis and Z-axis feed mechanism adopts dual ball screws and twin servomotors, enabling high-speed movement of large workpieces.

Featuring a high-quality spindle
The standard spindle is capable of handling a wide variety of machining jobs.  Providing powerful output of
55 kW and high torque of 1202 Nm, this superior quality spindle achieves low vibration to deliver superior machining quality. It also provides an optimum balance of impressive cutting capabilities in many different machining applications, including rigid tapping at 3,000 min-1.

MOTION
CONTROL

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.

CHIP MANAGEMENT

The four following features indispensable to reliable chip
removal are all standard on the a120.

-8-nozzle coolant supply device
-Overhead shower coolant system
-Center chip trough
-Chip conveyor

 
High-speed machining generates incredibly large volumes of chips. To ensure reliable chip removal, nearly all the covers in the machining chamber are oriented vertically. Coolant is discharged from nozzles on the spindle head and ceiling to flush chips into the wide center chip trough positioned directly under the table. A filtration system built into the chip conveyor ensures a constant supply of clean coolant. All of these features are provided as standard equipment for thorough chip evacuation.
