Mazak introduces the Ultimate Die & Mold (UD) 400/5X vertical machining center, which enables precise five-axis machining for smaller workpieces. Designed for applications including medical and dental instruments, mold and die components and others, the machine has a rigid base and double-column symmetrical construction that enable its spindle to reach high levels of precision and speed.

The integral 45,000-rpm HSK-E40 spindle, powered by an 18.5-hp motor, features temperature-controlled cooling oil that circulates through the spindle housing to provide stability for long periods of high-speed operation. Ballscrew-core cooling controls the temperature further, while 16 temperature sensors throughout the machine detect any other heat buildup. The machine’s thermal shield also controls for environmental temperature fluctuations.

The machine’s tilt/rotary table provides the machine’s full five-axis capability, accommodating workpieces weighing as much as 264.55 lbs and measuring as long as 15.75" in diameter and as tall as 11.81". The table’s B and C axes both utilize direct-drive motors that reduce vibration and heat buildup while enabling rapid traverse rates of 60 and 150 rpm, respectively.

Axis travels for the X, Y and Z axes measure 15.75", 21.65" and 13.78", respectively. The system also includes high-accuracy scale feedback on all its linear and rotary axes as well as high-specification linear guides for smooth movement. Optional machine features include tool-nose control and cutting-point control, while a 40-tool magazine supports continuous “Done-in-One” part productivity.

The system uses the Mazatrol SmoothX CNC control, whose functions include Variable Acceleration Control (VAC) to enable operators to utilize the high-speed linear axes when possible, Seamless Corner Control (SCC) to optimize acceleration and deceleration around corners, and Active Vibration Control (AVC) to minimize vibrations at the program level. These systems combine to significantly reduce cycle times and boost part accuracy.
