Advantages of 5-axis machining centers in mold machining and precision machining
Process integration
The UD-400/5X is capable of continuous machining of multiple surfaces and free-form surface machining by simultaneous 5-axis control, without the need to change setup.
By integrating multiple processes with a single chucking, production lead time and setup errors can be reduced.
Reduced tool protrusion length
When machining near-vertical areas with small-diameter tools, 3-axis machines require long protruded tools, limiting machining conditions such as feed rate. The UD-400/5X has a tilted table and a short tool protrusion length for stable machining. This allows the machine to function in its full potential.
Improved surface quality
The peripheral speed of the tip of the ball end mill is always zero, and machining a plane surface vertically on a 3-axis machine will reduce the accuracy of the machined surface. On the other hand, the UD-400/5X can tilt the workpiece to allow machining in areas where the tool peripheral speed is high, thus improving the quality of the machined surface and ensure stable surface accuracy.

Built-in motor spindle
The integral spindle/motor design can minimize vibration during high-speed operation to ensure exceptional surface finishes and maximize tool life.
Spindle core cooling
Temperature-controlled cooling oil circulates through the spindle core and housing to ensure stable machining accuracy over extended periods of high-speed operation.
1: Spindle center cooling 2: Housing cooling
Mineral cast
High damping mineral castings are used for the base and column. Vibration is suppressed even during high-speed operation.
High accuracy scale feedback
High accuracy scale feedback is equipped on the X-, Y-, Z-, B-, and C-axis.
By detecting the absolute position, higher accuracy machining during thermal expansion can be performed.
Direct drive motor utilized by B- and C-axis
Direct drive motors are used for the B- and C-axis.
Since this eliminates drive systems with belts and gears, there is no vibration, heat generation, and backlash. High-accuracy machining is ensured.
High Accuracy
MAZACHECK: 5-axis turning
To improve the accuracy of the machine, misalignment and tilt of rotary axes are easily and automatically measured and offset on an easy-to-understand operation screen. In addition to offsetting position deviation traveling parallel to the linear axis, angular deviation due to tilt direction can also be corrected.
THERMAL SHIELD: Heat displacement control
THERMAL SHIELD is an automatic compensation system for room temperature changes, which realizes enhanced continuous machining accuracy. MAZAK has performed extensive testing in a variety of environments in a temperature controlled room and has used the results to develop a control system that automatically compensates for temperature changes in the machining area.
Stable machining accuracy can be obtained over a long period of time without difficulty in countermeasures against thermal displacement.
