For more than 25 years, German lathe manufacturer Index has produced and sold worldwide more than 3000 ABC series twin-spindle, twin-turret turning centres, including many into the UK and Irish markets through sole sales and service agent Kingsbury. Now, the fixed-headstock, 65 mm capacity, CNC bar auto has undergone a series of improvements that allow it to address today’s requirement to machine more complex components in smaller batch sizes.

Index’s new model occupies an identical footprint and the working area is essentially the same as before. The latter is especially important to meet the needs of current ABC users by ensuring that existing part programs run without any increase in cycle time or loss in machining quality.

Over the years, the robust, slant-bed lathe has seen ongoing improvements, including to the control and drives. With the latest revision, a notable upgrade is that the upper live tool carrier has gained Y-axis movement and is capable of continuous indexing via a step-less gearbox, opening up many more machining possibilities. Additionally, the turret has centre height adjustment and can be equipped with double tool holders in seven stations for more comprehensive machining of component front ends in the 27 kW/6000 rpm main spindle using up to 14 static or driven tools.

An eighth position in the top turret houses a 4500 rpm synchronous spindle for reverse end-working on a parted-off component in conjunction with five tools, two of which may be live, in a back-working attachment mounted on the headstock.

Control is either by a Siemens S840D sl with Index’s own Industry 4.0 iXpanel, or by a FANUC 31i-B.
