UPFZ - 2-axis tilting head

The main feature of the UPFZ is the 2-axis tilting head. It enables the spindle to work vertically, horizontally or even diagonally in the working area. Thus, the spindle can machine the fixed workpiece from all five sides as it can move in any position around the workpiece, including an inclined position. Depending on customer requirements, various versions are possible for choosing how to arrange the angle positions.

The UPFZ 50 is obtainable with the tilting head in a stepless positioned version. Here, the head automatically undertakes intermediate positions in angle steps of 0.001°. During the individual machining process, the tilting head remains clamped. The complete unit of the UPFZ tilting head is mounted on vertical Z-slides and can be swivelled around the X-axis in a range of 180° during workpiece machining by the A-axis. In addition to this, there is also the possibility to swivel the main spindle in the tilting head by the B-axis with a tilting range of 360° around the Y-axis (compared to the standard setting). The standard head setting, A- und B-axis = 0°, is normally set as the vertical position to the operator side.

The specific tilting head construction enables, for example contrary to the fork head solution, the entire Z-movement in a vertical as well as in a horizontal spindle setting at lower portal height. Any potential travel loss arisen by reason of the swivelling movements can be compensated by the expandable Y-stroke at the portal carrier that can be increased up to 1000 mm opposite the table width.
