Multifunctional vertical turning center

The machines of the AC-1 series are highly flexible and predestined for the complete machining of different batch sizes, with very high quality requirements. The design as a right-hand or left-hand machine concept realizes the ideal adaptation to the production sequence. Highly productive simultaneous machining in one machine with up to two powerful disk turrets (4 axes) or several grinding spindles enables intelligent technology processes with high savings potentials and creates high-precision machining results.

With the two-spindle UNIVERTOR AC-2, simultaneous machining of two workpieces or machining of one workpiece in two clampings is possible. It has the same modularity and flexibility as the UNIVERTOR AC-1. The possibility of technology integrations of innovative processes such as rotation turning, hard turning, grinding, drilling or milling results in a significant reduction of in-house logistics processes and creates high-precision machining results.

4-axes machining
Highly productive simultaneous machining in one machine with two powerful disk turrets (4 axes). Intelligent technology processes and the combination of different machining steps offer high savings potential. Working with two tools simultaneously shortens the machining times of the workpiece and reduces the cost per part.


Rotational turning
With the rotation turning process developed and patented by WEISSER, precisely machined surfaces can be generated with twist-free finishing precision and thus replace the expensive grinding operations. The simultaneous rotation of workpiece and tool cutting edge reduces the machining time by up to 77 % compared with hard turning.


Hard turning
Hard turning describes the turning of steel with a hardness of more than 45 HRC. It is an efficient alternative for grinding hardened workpieces. The advantages of this process are shorter cycle, set-up and tooling times as well as the relatively lower investment costs and the options of wet and dry machining.


Out-of-round turning
3 times capacity with WEISSER HOT system for shorter piece times and lower piece costs. The technology enables the highly productive machining of a wide range of workpieces, such as pistons for combustion engines, camshafts, polygonal profiles or the production of polygon shapes (shaft-hub connections) with process-oriented perfection.


Internal / external grinding
Machining with the technology of external and internal cylindrical grinding in one machine is exemplary for perfect hard fine machining of rotationally symmetrical workpieces. In order to achieve optimum cycle times, this machining technology can be combined with hard turning or rotational turning processes.


Gear cutting (hobbing)
Integration of a hobbing module, being the only method to manufacture internal and external gearings with different helix angles and directions in a single machining center. This manufacturing process combines hobbing and slotting by continuous hobbing with maximum feed rate.
