Step 3: cutting process, incudes according to round tube (49) data and probe, the second servo motor (47) work is automatically controlled, Second servo motor (47) work is rotated by the second screw rod (17), to push third sliding block (14) before and after guide pipe (16) It is mobile, it pushes cutting head (15) to reach designated position by guide post (18), then carries out positional dissection;In cutting process Three servo motors (37) work drives driving pulley (38) rotation, drives driven pulley (36) rotation by synchronous belt, drives master Axis rotation drives round tube (49) rotation by cohesion device (2), realizes circumgyration incision;Feed device is controlled in cutting process (3) cutting of the different shape pattern on round tube (49) is realized in revolving speed and the steering of back-and-forth motion and cohesion device (2).
