The U20K-852H Ultrasonic Vertical Machining Center features roller linear guideways on the X, Y, and Z axes, with a counterweightfree structure on the Z axis, ensuring high speed, high precision, and high stability and reliability. Equipped with an ultrasonic spindle and a highpower, hightorque digital ultrasonic control auxiliary system, the machine significantly improves production efficiency and product quality while reducing manufacturing costs. In particular, for highprecision machining, micromachining, and processing of complex materials, it can multiply both productivity and yield. The machine is suitable for the efficient processing of complexshaped parts, difficulttocut metal materials (e.g., hightemperature alloys), ceramic materials (e.g., alumina), optical materials (e.g., optical glass), and composite materials (e.g., carbon fiber).

Machine structure: The machine has a Cframe configuration, featuring a herringbone, widespan column structure. The contact span between the base and the column is 1210 mm. The Y axis also adopts a widespan design with a span of 800 mm, ensuring high stability and longterm accuracy retention. Together with the boxtype slide and base, the machine exhibits excellent rigidity. Castings are made of highstrength cast iron, effectively suppressing deformation and stress caused by cutting forces during machining.

Feed drive system: The X, Y, and Z axes adopt linear guideways, with the Zaxis guideway using three slide blocks. The machine is specifically designed for high speed and high rigidity. The screw fixation employs a new “one face, one pin” locating method, greatly improving axial rigidity and its retention. The three axes achieve a rapid traverse of 48 m/min. AC servo motors directly drive highprecision, pretensioned, largelead ball screws, resulting in fast, smooth, and steady axis movement, providing longlasting precision.

Spindle system: The machine is equipped with a highpower, hightorque ultrasonic spindle (taper BT40) featuring brushless and contactless conduction, with a power output adjustable from 1000 to 3000 W by waveform frequency. An oscilloscope enables realtime monitoring of waveforms and frequency. The spindle’s maximum speed is 8000 r/min, effectively ensuring part accuracy and surface finish.

Tool magazine: Disctype tool magazine, reliable and stable performance. Tool change is performed by a tool change arm; magazine capacity is 24 tools, with fast toolchange time.

Machine guard: Full safetystandard guarding prevents coolant splash and ensures safe operation.

Control system: The machine comes standard with either FANUC 0iMF, Siemens CNC, or Huazhong CNC, all featuring reliable and excellent performance.
