Central head MX-RAM series

MX floor type boring-milling machines are distinguished for having central headstock in the column.

The innovating “box in the box” concept, introduced by JUARISTI in this type of machines with a symmetric column and completely closed centered headstock, has established a tendency followed by other manufacturers.

This feature is a key factor to guarantee a good mechanical and thermal behaviour in all machine structure, with regard to the cutting forces and thermal dilatations.
