Efficient Solutions for Industrial Needs
High-Speed 5-Axis Machining Center UZ Series
A high-precision 5-axis vertical machining center with an umbrella-style tool changer, featuring extremely fast tool-to-tool change times
Precise and efficient 5-axis machining center UZ
The UZ320 is a high-precision 5-axis vertical machining center that utilizes an optimized cross-slide design. This design ensures excellent positioning accuracy and stable dynamic response during machining. The machine’s linear X, Y, and Z axes offer travel ranges of 500/500/400 mm, and its integrated motor spindle reaches a maximum speed of up to 24,000 r/min. The intelligently designed spindle oil chiller and the electrical cabinet’s air conditioning system maintain stable temperatures even under demanding conditions.
A key strength of the machine is its umbrella-style tool changer. This umbrella-style magazine enables fast and reliable tool changes controlled by a gripper, and it accommodates 21 tools as standard. An efficient chip conveyor, a bed flushing system, and an automatic coolant system enhance machining comfort and cleanliness. A fully enclosed protective cover effectively shields the operator. An electric handwheel simplifies control, and modern Ethernet and USB ports facilitate data transfer. This compact machine, weighing 4,900 kg, is designed for the efficient milling of complex and precision parts.

Guidance
Available with both Fanuc and Siemens controls. These familiar and powerful controls make commissioning easy and seamless. Of course, Siemens and Fanuc also offer the option of 4- and 5-axis machining.
Automatic Tool Measurement
Automatic tool setting and workpiece measurement make the machine easy to use and help the operator save time.
Spindle-through cooling
Coolant is directed directly to the machining area and all the way to the tool tip by channeling it through the spindle and the channels inside the tool itself.
Spindle Oil Cooler
An oil cooler that regulates the oil temperature based on the room temperature can be installed on the machine, enabling long-term, continuous operation at high rotational speeds.
