With continuing to press on for expeller (5), the location of workpiece slotted is covered through the oblique section of transition (121) in the outer of swollen cylinder (11) On side wall, the inner wall of workpiece is bonded with the lateral wall of swollen cylinder (11), at this point, the crushing block (33) of corresponding swollen cylinder (11) position, It squeezes and is fitted in workpiece outer wall under the promotion of third cylinder (23), and driven by motor (43), do axis on workpiece lateral wall To reciprocating movement expect that the convex portion of line position is squeezed and smoothed out to groove body or expected the low side of line with the rotation of workpiece Position has been cut between sectional material line, and fluting increases filling space, and the spacing for formation of slotting makes the change that is squeezed The resistance of shape reduces, and can be extruded transmitting, in addition the elastic reaction of spring (8), expects that the convex portion of line is smoothed out, and Lower position is also filled, and the 6th cylinder (26) pulls pedestal (31) mobile to tailstock direction；

Then, workpiece position after extruding is moved to the position of grinding block (34), and the 4th cylinder (24) pushes grinding block (34) straight It connects and the lateral wall of workpiece is ground, at the same time, the inner sidewall of workpiece borrows the 4th gas in the case where the fitting of swollen cylinder (11) abuts The motive force of cylinder (24) is also ground the inner sidewall of workpiece；After the completion of grinding, the second cylinder (22) drives supporting plate 41 Return, the first cylinder (21) push liftout column (13), workpiece are released from swollen cylinder (11), the swollen cylinder (11) of workpiece disengaging it Before, by manipulator (6) anchor ear, and it is mobile with the rate of liftout column (13), workpiece, the 7th cylinder are finally removed from swollen cylinder (11) (27) screw tap column (12) are pushed to return to initial position, the 6th cylinder (26) pushes pedestal (31) to return to initial position；

In the process, when second sensor (72) is moved to first sensor (71) position, screw tap column (12) at this time is It being retracted in swollen cylinder (11), expeller (5) no longer abuts workpiece, and controller 7 starts the 5th cylinder (25) and withdraws expeller (5), Workpiece is covered completely on swollen cylinder (11), pulls pedestal (31) to move to tailstock direction at this point, starting the 6th cylinder (26) from controller 7 It is dynamic, persistently workpiece is squeezed and ground.

7. a kind of final polishing method of removal surface material line according to claim 6, it is characterised in that: the main shaft turns Speed is 800~1000R/min, and the rate travel of the 6th cylinder (26) is 1~3mm/s, the groove body for formation of slotting Groove depth is 0.3~0.5mm.

8. a kind of final polishing method of removal surface material line according to claim 6, it is characterised in that: the crushing block (33) width is 15~20mm, and the thrust size of the third cylinder (23) is 1960N, the rotational frequency of the motor (43) For 2500~3000Hz, under the drive of the motor (43), the distance that the third cylinder (23) moves back and forth is 10~15mm.

9. a kind of final polishing method of removal surface material line according to claim 6, it is characterised in that: the 4th cylinder (24) thrust is 8200~9800N.
