[UD-400/5X]

Yamazaki Mazak has released a new simultaneous 5-axis machining center, the UD-400/5X, designed for fine and precision machining of die molds and medical device components.

The machine features enhanced structural rigidity, including the base and column, and improved vibration control in the drive system, such as the ball screw and linear guide. By reducing vibration, the machine ensures high surface quality, even during machining with high acceleration and deceleration.

Additionally, the use of a symmetrical double-column structure minimizes frame distortion caused by temperature fluctuations, helping maintain stable machining accuracy. The machine is equipped with the company’s fastest spindle, capable of 45,000 rpm.

A direct-drive motor is used for the tilt table. Temperature-controlled coolant circulates through the spindle and the center of the ball screw axis, reducing the effects of heat generated by the motor and ball screw. This design minimizes vibration, thermal displacement, and backlash—factors that can reduce productivity and machining quality—and enables each drive system to operate with high speed and high precision.

Each axis is also equipped with high-accuracy scale feedback and a thermal displacement control system called “Thermal Shield.” This function compensates for thermal errors in real time, allowing for highly accurate machining.
