Mazak has introduced the precise Ultimate Die & Mould (UD) 400/5X vertical machining center (VMC).
Designed for applications ranging from medical and dental instruments to mould and die components and beyond, the machine features a rigid composite base and double-column symmetrical construction that allow its state-of-the-art spindle to reach the highest levels of precision and speed.
The integral 45 000rpm HSK-E40 spindle, powered by a 14kW motor, features temperature-controlled cooling oil that circulates through the spindle housing to provide stability for even long periods of high-speed operation. Ball screw core cooling controls the temperature further, while 16 temperature sensors throughout the machine detect any other thermal displacement. The machine’s thermal shield also controls for environmental temperature fluctuations.
The machine’s tilt/rotary table, which gives the machine its full simultaneous 5-axis capability, accommodates workpieces weighing up to 120kgs and measuring up to 400mm in diameter and 300mm in height. The table’s B and C axes both utilise direct-drive motors, enabling rapid traverse rates of 60rpm in the B-axis and 150rpm in the C-axis.
Axis travels for XYZ measure 400 x 550 x 350mm. The UD-400/5X also includes high-accuracy scale feedback on all its linear and rotary axes as well as high-specification linear guides for smooth movement.
Mazak pairs the UD-400/5X with its Mazatrol SmoothX CNC control for a high degree of precision and performance, especially for machining dies and moulds. The control’s suite of Smooth Technology functions includes: Variable Acceleration Control to allow operators to utilise the high-speed linear axes when possible; Seamless Corner Control to optimise acceleration and deceleration around corners and Active Vibration Control to minimise vibrations at the programme level. All of these functions may be combined to reduce cycle times and boost part accuracy.
