The automatic HE-grinding machine & loader + EDM nozzle is used for the flow calibration of injection components.
Based on a rotary table concept, the workpieces pass through various processes in successive stations: Pre-measuring –
HE grinding- Blowout – Flushing – Final measuring – Blowout. During the HE grinding process, an abrasive fluid is pumped under high pressure through the workpiece bores to round off. Depending on the application, the flow rate is increased by
8 % – 30 %. The grinding process is stopped as soon as the correlated desired flow value has been reached.
The loading and unloading of the module is carried out automatically by a 4-axis robot which grips the workpieces from pallets and inserts them into the rotary table.
For safe pallet detection, the DMC code is read in on the pallets by means of a DMC camera and the dot code on the workpieces is also read in by means of a camera for part detection and for seamless data traceability.
The module has a swiveling control panel with a comfortable user interface. Processes and their results are clearly visualized. In the case of modified processing and test requirements, a quick adjustment of the parameters is easily possible.
