The Cincom A20-VIILFV can be used with a guide bush as a conventional Swiss-type automatic for machining shaft-type workpieces, or without one for producing shorter parts from less expensive stock while achieveing minimal bar remnant wastage. The guide bush can quickly and simply be mounted and removed. In sliding-head mode, machining length per chucking is 200 mm to reduce cycle times when producing long, slender components.

The 7-axis A20 machine platform, which is capable of 2-axis simultaneous cutting, offers a high performance-to-price ratio for the production of parts from 20 mm diameter bar, optionally extendable to 25 mm (1 inch). The main spindle is rated at 3.7 kW/10,000 rpm for optimal machining of smaller diameter stock and has an opposed 1.5 kW/8,000 rpm sub-spindle with an X2-axis enabling simultaneous machining on the front and reverse ends of components. Both spindles have one-degree indexing and a 0.001-degree C axis.

Tool capacity is 21, with four driven stations for cross machining having a maximum speed of 6,000 rpm. The four back tool post stations may optionally be live. Positioning speed is fast at 32 m/min for short non-cutting times. Idle times can be reduced further using the pre-processing function in the Fanuc-based Cincom control dedicated to this machine model. It analyses the machining program before it is run to minimise processing and calculation times.
