MX-RAM Series

Travelling column boring – milling center with central head

Travelling column boring centers with exclusive design

The MX series is a premium solution featuring precision, rigidity and dynamism, the result of more than 20 years of experience in designing this series.

The “box in box” concept introduced for the first time by JUARISTI on this type of machine, with a symmetrical column and completely closed central head, provides the machine with optimum rigidity, accuracy and dynamics.

Maximum precision thanks to the box-in-box design.
Thermo-symmetric structure.
4-sided RAM and vertical stroke guiding.
High dynamics (up to 30 m/min).
Multiple multitasking options.

Reduction of thermal distortion thanks to the thermo-symmetric structure.
Double real-time geometrical compensation of the head + RAM assembly centre of gravity and RAM flexion.
Ergonomic operator platform with three independent movements in X-Y-Z directions.
Machining up to 7 m high, 5 m wide parts.
Large RAM travels: 2,000 mm on the milling machine and 1,900+1,000 mm on the boring machine.
