machine description

Diskus double surface grinding machine



with horizontal spindles.



This machine type is a steel-box frame welded construction with two opposing horizontal grinding spindles with the same axis. These are directly driven, liquid cooled motor driven spindles whose main spindle drives each have a motor output of 24 kW to 100 kW.



Various types of workpiece transport are possible. Linear workpiece feed can also be selected, depending on the workpiece geometry. In this case, the workpieces are fed and guided with the help of guide rails for the grinding tools. At the discharge, Diskus's own ionic 100 % measuring control measures each part.



The measuring results from this post-process measuring control are transferred to the SIEMENS 840D machine control and used for automatic correction as required.
