UNX Series

The UNX series is designed to meet the challenges of off-center holes with extreme depth-to-diameter ratios. These machines automatically drill deep holes in long, heavy workpieces without a loss of accuracy. And the UNX50 model is capable of executing both gundrilling and BTA deep hole drilling.
There are three motion profiles available to fit your needs:
C

Cartesian positioning [C] maintains a stationary workpiece and moves the drilling headstock in the X and Y axis.

P

Polar positioning [P] rotates a cylindrical part on its axis, with an X-axis to position the drilling headstock distance from the center.

CP

Cartesian and Polar positioning [CP] are combined with advanced motion control to achieve the highest accuracy in small diameter, extreme depth drilling.
