Following this, the pneumatic cylinder 4, the carriage 2 is translated to the left before coming into contact with the microswitch 7, tresana fin edges 11 and 22 on the other side of the microneedle.

At the end of pieces of work microswitch 24 and will switch the pneumatic cylinder 13 on the reverse, and pneumatic cylinder 4 feeds the carriage 2 in its initial position where it is locked by the latch 8. Clip 3 with the workpiece to cut the Burr is removed from the carriage 2, and in its place installed another clip with the new billet microneedle. Next, the operation of the device is performed in the order described below.

The device provides high precision cutting Burr in semi-automatic mode.
