A machine synonymous with the history of Cincom has been designed for the new age with 3 models in a modular design.a

Ranging from a 5-axis machine with excellent cost performance to a high-end machine equipped with B axis and a back spindle Y axis, you can select the machine according to the functions you require.

This concept offers unrivaled versatility – two types of gang tool post, five types of opposite tool post and three types of back tool post are available to be specified according to the functions required.

Each model can be specified to deliver the functions you need: from simple to complex workpieces and for small, medium and large lot sizes.
