    2 - TECHNICAL INFORMATION MASTER 880MP E-volution OPERATING CYCLE The automatic functioning controls the motions of the bar feeder according to the sequence described below. The bar pusher (A) makes bar (B) move forward in the lathe until the bar runout. The bar-pusher (A) and remnant (C) are in their forwards limit stop position.
  • Page 17 2 - TECHNICAL INFORMATION MASTER 880MP E-volution When dropping, bar remnant (C) activates a control device. If the bar remnant is still inside the collet of the bar pusher, the bar feeder stops, otherwise the cycle goes on. The top guides (G) are lifted together with the bar pusher (H), and also the bar control devices are lifted.
  • Page 18 2 - TECHNICAL INFORMATION MASTER 880MP E-volution Bar lifts (L) load bar (M) that falls into lower guides (N) with the help of levers (H). The 1st feeding carriage (P) stroke begins. When the small pusher truck (P) completes its stroke, the required space has been created for bar-pusher insertion.
  • Page 19 2 - TECHNICAL INFORMATION MASTER 880MP E-volution The upper guides (G) are closed; the bar-pusher (H) is positioned along the spindle axis. The clamps (D) close, the bar-pusher (A) moves forwards; the bar (N) is inserted into the bar- pusher collet. The bar-pusher (A) and bar (N) execute their facing stroke.
