CITIZEN A20VII HORIZONTAL MACHINING CENTER

Technical Description

The CITIZEN Cincom A20VII is a 7-axis sliding headstock CNC lathe engineered for high-precision small-part machining. This machine features a main spindle with a maximum turning diameter of 0.980" (20mm) and turning length capability of 7.870" (200mm), complemented by a sub-spindle for simultaneous front and back machining operations. The main spindle operates at 10,000 RPM with 3.00 HP output, while the sub-spindle runs at 8,000 RPM with 2.00 HP, enabling efficient dual-spindle processing. The machine accommodates 21 total cutting tools including 4 live tools, 5 turning tools on the gang tool post, 8 back-end tools, and 4 front-end tools, allowing for comprehensive machining without repositioning. With 7 axes of motion, the A20VII delivers rapid traverse rates of 709 ipm across the X, Y, and Z axes, significantly reducing cycle times through fast 32 m/min rapid feed rates. The machine's guide-bushing-convertible design provides flexibility for both guided and non-guided bushing operations, with maximum machining lengths reaching 200mm in guide-bushing mode and up to 2.5D (55mm maximum) in guide-bushing-less mode. Controlled by a Fanuc Series 32i CNC unit, this cost-effective machine is recognized for delivering exceptional capability and throughput optimization at an attractive value proposition for precision component manufacturing.
