Nothing but Physics

The workpiece is clamped with its centre of rotation and tilting in centre with the y-axis. (Fig.1)

Now the articulated arm of the x-axis is lowered until the centre of mass (balance) of the workpiece is set. (Fig.2)

Note:
If the centre of mass of the workpiece is outside the adjustment range it can be shifted into this range by means of counterweights.

The workpiece to be machined is in balance and can be moved easily into any position. (Fig.3)

Therefore, the machining of the workpiece is significantly easier for the user. Furthermore, an ergonomic working height can be adjusted for both sedentary and standing work. (Fig.4)
