EMERA
moving column milling machine up to 8 axes

Born to tackle tough materials
The Emera moving-column milling machine is designed to attack very hard and tough materials with high removal capacity.

Rigidity and precision
The Box-in-box design combined with the octagonal RAM and DualDrive Technology system make this moving column milling machine extremely rigid and sturdy, ideal for machining medium to large workpieces with capacities up to 10 tons.
Versatility
With its automatic head-change system, Emera can transform from a 5/8-axis milling machine to a vertical lathe with a vaulting diameter of 2,000 mm in just a few minutes (optional).
Customizable X, Y, Z axes
Some examples of EMERA milling machines’ configuration

Box-in-Box Construction
To minimize vibration and bending during heavy removals, EMERA moving-column milling machines are built with the Box-in-Box system, which shifts drive forces toward the center of gravity. Sturdy slide rails support the ram on both sides and distribute forces evenly to ensure high speed and acceleration.
The result is a large material removal capacity while maintaining high levels of precision throughout the machine volume.

Octagonal RAM
The octagonal RAM represents a unique structure that provides excellent stiffness and does not undergo dimensional changes due to increased temperature. It also perfectly absorbs all vibrations generated by cutting forces during heavy machining.
Unlike square RAMs, this system does not require the use of preload tie rods, as the octagonal geometry itself minimizes RAM dropping during useful stroke.

DualDrive Technology
Thanks to DualDrive Technology, with rack and two pinion gears, we can guarantee significantly higher precision, speed and stable acceleration than that of other conventional systems, reaching values of up to 40 m/s and 1 m/s2.
Compared to a recirculating ball screw, this system always remains very accurate over the years, quieter, not sensitive to wear, reducing downtime and zeroing maintenance expenses*.
In addition, compared with the linear motor, it can reduce power consumption by up to 5 times* without producing heat.

RAM heads
Unconstrained
All the heads we use are at 360,000 torque positions. This means that they are not restricted to specific angles, such as the index ones, but can work in any position of rotation of half-body C and half-body A.
Automatic head gearbox
To perform different machining operations automatically, EMERA moving-column milling machine can be equipped with the rapid head change system. This makes it possible to turn a 5-axis milling machine into a multitasking machining center, ready to perform several machining operations with a single machine.
