aschine wurde vor wenigen Jahren aufwendig überholt und modernisiert: U.A. - Zustellung über Schrittmotor wie bei JR300 bzw. JF520 - Querachse umgebaut auf Kugelrollspindel - Mit elektrischem Antrieb - SPS Steuerung Heidenhain Maßstäbe mit Digitalanzeige Vor Verkauf wird sie komplett demontiert neu lackiert Dicht- und Verschleißteile gewechselt sowie geometrisch überarbeitet.

Partly overhauled according to Jung measurement protocols - Heidenhain digital readout at the feed axis - Automatic feed with switch-off - Stepless adjustable grinding spindle - New grinding spindle - Scraped guidance – rotary table - New hydraulic lines - New electric lines - New plugs, sockets and buttons Complete demontage and cleaning Ckecked machine guidance Changed spare parts and wear parts Die Werkzeugmaschine entspricht zum derzeitigen Zeitpunkt nicht den grundlegenden Sicherheits- und Schutzanforderungen wie in der BetrSichV 2015 genannt. Eine Anhebung des erforderlichen Mindest-Schutzzieles ist mittels einer Gefährdungsbeurteilung nach BetrSichV zu ermitteln.
