Description

non-gay 16 at right angles to the first. The screw 17 moves the tool holder B in the transverse direction. On the left end of the feed screw 14, the half-coupling 18 is connected to activate the drive in nta 17,

To avoid spinning in axial and right-singing, the ring support can be equipped with a known strap-up mechanism at the time of grooving the collar.

The device works as follows

The bed 1 is fastened at the end face of the machining part 19. The drive 3 is turned on and the planet carrier 6 is led into the circular rotation around the eccentric support 8; Therefore, it is said that the screw 14 is evenly screwed in and that the ring support 4 is moved with the tool holder 5 in the axial direction. At the end of processing the cylindrical surface of the product 19, the stop 10, abutting against the “geics of the annular support of the drum 2, receives an axial movement opposite to the movement of the caliper 4 until the ledge 12 of the threaded sector of the nut 13 comes into the depression 11 of the stop 10 and does not open the nut 13. So stop the axial flow of the caliper 4.

Simultaneously with the cessation of the axial ringing of the ring caliper, the gear — the half-coupling 15 enters the hook (not with the half-half 18 n begins to transmit the rotation to the nut-nut 16. The latter acts on the screw 17, which, being rigidly fixed in the tool holder 5, mixes the reeceter “a transverse direction, at the end of the cutter stroke

drum off /

If necessary, repeat the transition. The ring caliper is brought to the original floor. Reduction.
