Cincom L12VII : CITIZEN MACHINERY CO., LTD.

Sliding Headstock Type Automatic CNC Lathe

It realizes increasing the maximum speed of not only the main spindle but also the back spindle and rotary tools. In addition to simultaneous machining with 5-axis control, it reduces cycle-time

It adopts horizontal tool layout that is one of features of L series, and flexibly corresponds to various complex machining with a wide variety of rotary tools

The switch between the guide bushing type and the guide bushing less type can be accomplished in a simple operation. It achieves a reduction in running costs
