The index is designed to utilize a three-piece precision face gear coupling. It is an ideal accessory for NC borers, CNC machining centers as well as semi-automatic precision millers, borers etc.. Because of the preset function control used for the indexer, highly accurate proisitioning can be carried out by 5° increment. The indexing is performed by applying air pressure.
The spindle nose has a standard register taper. The workpieces mounted on the face plate can be easily positioned and machined. If a chuck with short taper recess is fitted onto the spindle nose, larger or longer bars can be held. When using 5C or 3J collet in the spindle bore, smaller or shorter hard drawn bars can be held for machining. With the help of centres on indexer and tailstock, cutting of long shaft can be performed.
