MASTER 880 MP bar feeder gives maximum flexibility
To complete the MASTER 880 project in the rack and bundle versions, IEMCA has unveiled its new MASTER 880 MP feeder (Single-rack).
The SIR multi-spindle feeder is a complex machine with a revolver, which holds the bars to be machined by the different spindles on the lathe.
The revolver can contain 5, 6 or 8 bars, that are machined at the same time on different stations.
At the end of the machine cycle, the finished section is cut, then the system pushes the bar forward for the next cycle.
The critical aspect of the process is the synchronisation with the lathe and the precise feeding of the bar.
Thanks to the technological input by Siemems in the new PLC S7 300 C (process interrupt, analogue inputs, analogue outputs, reduced scanning time, functional blocks, communication protocols), today IEMCA is able to implement innovative technical features on its own multi-spindle feeders, to further improve functions and overall performance.
