Cincom A20 VII

Acclaimed for its excellent cost to performance ratio, this next generation A20 has evolved as a 5-axis machine (plus C1 & C2 as MCC standard) for ∅ 20 mm applications, with the advantage that it can be used with or without the easily mounted and removed guide bushing.

The high speed 10,000 rpm spindle enables optimized machining operations on smaller diameter bar material. The machining length per chucking is now extended to 200 mm enabling the number of re-chuckings and therefore cycle times to be reduced when machining long workpieces. As an option, bar material up to ∅ 25 mm can be machined extending the range of work pieces.

With its Fanuc Series 32i Model B System Control, the A320 offers quick setups and high speed, high precision performance. And with the additional X2 axis, front/back simultaneous machining is possible.
