Geometrically overhauled and newly painted according to Kellenberger measurement protocol. Completely new electrics with new infeed control. Bodpfx Aaed Ih Ege Dslk Photos show a previously delivered machine of the same design, but with 1500 mm centre distance and universal grinding head instead of the 500 mm wheel head, purely for external cylindrical grinding purposes. Equipment: - 2-axis digital readout - New DGS paper band filter Optional at extra charge: - Semi-automatic dressing - Dressing size compensation - GAP Control - Measuring automation - Safety doors Electronically controlled infeed system with stepper motor drive. Hydraulic table longitudinal and rapid traverse movement. Powerful, non-swiveling grinding spindle headstock for production external cylindrical grinding operations. Areas of application: Machining of high-precision components in the gearbox, machine tool, and general mechanical engineering sectors. Pair grinding for the hydraulics industry. At present, the machine tool does not meet the basic safety and protection requirements such as those specified in BetrSichV 2015. The required minimum safety objective must be determined by means of a risk assessment according to BetrSichV.

Būklė: naudotas, Gamybos metai: 1982, Grinding diameter 630 mm Grinding length 600 mm Centre height 320 mm The machine was overhauled according to the Kellenberger inspection protocol and newly repainted. The prone-to-failure Güttinger control system was replaced with the modern BEMA X control system. This means the machine also received a completely new electrical system as part of this upgrade. Machine equipped with a reinforced workpiece spindle head for chuck grinding of heavy workpieces. Currently, the machine does not meet the fundamental safety and protection requirements specified in the German Ordinance on Industrial Safety and Health (BetrSichV 2015).
