Contrary to our TWINFLEX G with 2 stations, this special design disposes of 1 station: 1 rotating bridge, but 2 machining units.

It was an important requirement of the customer of
MAG Witzig & Frank that several different workpieces could be machined by one single machine. Besides that, the final product should be a machine that would be failsafe, i.e. not allowing for any operating error. Therefore, e.g. no tool changer as provided and a turret was used.

The machine is equipped with 3 clamping fixtures, i.e. for the front and the rear casting knot (each left and right) and the assy. rear axle carrier. Our proven fixture quick-change system provides for a swift change of the parts.

The aluminium parts are machined by dry operation or with minimum quantity lubrication respectively.

It has to be added that, due to the tools not being removed from the turret spindles, there may not occur any trouble by flocked chips on the workpiece shaft. This guarantees not only a high availability but also an invariable quality of the workpieces to be manufactured.

A further outstanding feature of this equipment is the prevention of failures. Thus the control verifies the suitability of the fixture present as well as of the tools mounted or introduced to the corresponding turret positions for the selected NC program. This is achieved by chip coded tool holders as well as corresponding reading devices. Thus the workpiece may reach on the clamping fixture only one clearly defined position. The proper position of the workpiece is checked by a compressed air unit that avoids any improper clamping.
