UD-400/5X VMC Delivers Micro-Precise High-Speed Machining

Mazak’s Ultimate Die and Mold UD-400/5X vertical machining center delivers five-axis machining in a small footprint platform. The VMC can be used for applications ranging from medical and dental instruments to mold and die components and sports a rigid base and double-column symmetrical construction.

The 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 ensure 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 accommodates workpieces weighing up to 264.55 lbs and measuring up to 15.75” in diameter and 11.81” high, and it gives the machine its full simultaneous five-axis capability. The table’s B and C axes both use direct-drive motors that are said to eliminate vibration and heat buildup while enabling traverse rates of 60 rpm in the B axis and 150 rpm in the C axis.
