engraflexx ESP / VA-175

A core element of the engraflexx ESP is the laterally deflecting, electric spindle with infinitely variable speed adjustment. This consists of an air-cooled high frequency motor with integrated collet chuck for tool clamping.

Thanks to the tried and tested electric drive, efficiency and process-safety are among the special characteristics of the spindle.
The spindle (start/stop command, speed specification etc.) is actuated via the frequency converter that is connected to the robot and the higher-order machine controller.

This tool system is used for deburring work or part reworking on robots or special systems. Anywhere where workpiece areas that are difficult to access (for example recessed lying in housings etc.) are being machined on workpieces whose dimensional or position differences have to be compensated for automatically and with maximum process-safety.

Field of application

Deburring and reworking of workpiece areas that are difficult to access
with different or undefined edges.
