As a FM-cell, the machine facilitates automation of a manufacturing line, and because of its vertical type, enables handling of heavy workpieces While machining on No.1 & No.2 spindle , part loading and unloading is done on No.3 & No.4 spindle 5 seconds for carrier indexing time which is the only time needed for part loading / unloading Various machining method 1.Part reversing--Front and back side operation machining simultaneously or 2.Two parts at one cycle (w workpieces at a time )--Twin single operation leads to 1/2 cycle time or 3.Two different parts simultaneously on one machine--Part A and Part B machining simultaneously
