hydroerosive grinding HE-grinding machine pump components


The HE-grinding machine pump components has been designed for deburring high-pressure pump cylinder orifices.
The outlet direction is ground for a defined time.
During the grinding process an abrasive fluid is pumped through the orifices of the workpiece to radius the borehole intersections. For operating the machine a moveable control panel with a comfortable user interface is installed. In addition, the current process data and results are displayed.
The machine is loaded by means of a belt system with a Staeubli robot (4 axis).


  • Simultaneous grinding of all orifices
  • Time controlled grinding
  • Loading with a 4-axis Staeubli robot
