UNIVERTOR AS pick-up loading

Horizontal shaft turning center

Modular designed, single-spindle pick-up precision turning machine. Designed for complete machining of various batch sizes at low unit costs and with high machining and quality requirements. Due to the automation solution integrated as a pick-up system, no loading devices or separate robot solutions are required. The cross slide of the UNIVERTOR AS, that carries both the motor spindle and the NC tailstock, is designed horizontally. The tailstock and steady rests travel NC-controlled.

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.


External grinding
Machining with the technology of external 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.
