hydroerosive grinding HE-grinding bench high flow


The semi-automatic HE-grinding bench high flow has been designed for flow calibration of high-pressure injection components to a defined target. The single station is thereby loaded manually by the operator.
During the grinding process an abrasive fluid is pumped through the orifices of the work pieces in order to radius bore hole intersections. The flow will be increased and stopped as soon as the flow has reached the correlated target flow value.
A moveable control panel with a comfortable user interface is installed. Part data can be entered by a DMC scanner. Running processes and results are displayed. The parameters can be easily adjusted in case of changing requirements.
