including 30 different numeric error displays
Pneumatic workpiece-loading and unloading facility parallel to work piece axis upright for rod workpieces approx. 140 mm long x 8 mm , including pneumatic double gripper for
loading and unloading of work pieces. Raw parts are inserted into change cassettes externally and then placed into the loading device. The double gripper places the parts between workpiece spindle and tailstock,
the tailstock spindle sleeve pushes the parts in the main spindle collet and clamps them simultaneously.
The finished parts are ejected from the main spindle, then placed back again into the finished parts cassette by the gripper.
The whole process is electrically monitored and checked.
The complete loading facility is encased by plexiglass.
