The parallel kinematic concept
Three parallel linear axis drives are mounted radially equispaced in a barrel-shaped headstock. The spindle platform is connected to each drive by means of rigid levers with a simple pivot at one end, and a ball joint at the other end. A high performance motor spindle is mounted to the spindle platform.
The headstock is mounted horizontally and moves vertically inside the column. This arrangement offers minimum movable mass resulting in unprecedented dynamic characteristics.
When all three axes are moved equally and simultaneously,the spindle is moved in a straight line in Z-direction.
If the three axes move differentially, the spindle platform will be tilted in the A/B-planes. Synchronized motion of the three Z axes allows the spindle to describe any path within a spherical cone of ± 40 degrees.
- Cubic working area through linear motion of X-, Y and Z-axis.
- Conical working envelope with ± 40 degrees of angularfreedom.
