WHY BUY USED CITIZEN A20 TYPE VII 2012
A used 2012 CITIZEN A20 TYPE VII offers manufacturers an efficient solution for producing high volumes of small and complex precision components. Its Swiss-type sliding-headstock design provides excellent support for slender workpieces, allowing manufacturers to achieve tight dimensional tolerances while maintaining consistent production quality.
The machine’s ability to combine multiple machining operations into a single cycle is one of its biggest advantages. Turning, drilling, boring, threading, grooving, cross drilling, and backworking can be performed without transferring the component to multiple machines. This reduces work-in-process inventory, setup time, and secondary machining requirements.
The A20 TYPE VII is particularly valuable for applications requiring high production volumes and repeatable quality. Automatic bar feeding and parts handling can further reduce operator involvement and support extended unattended production.
For manufacturers producing small-diameter components, purchasing a used CITIZEN A20 TYPE VII can provide access to advanced Swiss-type machining technology at a lower investment than purchasing new equipment.
HOW MUCH DOES A USED CITIZEN A20 TYPE VII 2012 COST?
The price of a used 2012 CITIZEN A20 TYPE VII depends on the machine’s operating hours, spindle condition, guide bushing system, tooling configuration, CNC control, bar feeder, sub-spindle, live tooling, coolant system, and overall mechanical condition.
Machines equipped with an automatic bar feeder, sub-spindle, live tooling, high-pressure coolant, parts catcher, and additional tooling can command higher prices because these options significantly increase production capability.
Before purchasing, buyers should inspect the main spindle, guide bushing, sliding headstock, cross slides, ball screws, live tooling, sub-spindle, bar feeder, coolant system, and CNC control. Particular attention should be given to spindle runout, guide bushing condition, axis repeatability, and machine geometry.
