The two machine sizes specified in the name by the maximum machining diameter (180 mm or 280 mm) allow for high productivity including right spindle machining.
Five technological versions for each machine size allow for the perfect choice of your technology from small-scale production to specialized mass production.
The solid base of the machine and the bed ensure high stiffness of the machine.
Deformations of mechanical components of machines are verified using numerical calculation methods – FEM.
Dynamics and stability of the axle movement are checked using modern calculation methods
Spindle units provide high machining efficiency.
The built-in spindle synchronous motors provide high spindle dynamics and efficient rotary C axis.
Line axle support, right headstock or tailstock travels on the track guide, providing high positioning accuracy and interpolated axle movement.
The rigidity of the three-axial version of the upper slide emphasizes the solution with the virtual motion of the Y1 axis, which consists of the interpolation of the real axes X1 and Y ‘including the angle of 30 degrees.
Programmable movement of the tailstock body reduces unnecessary tampering in the machining process
The choice of modern control systems SINUMERIK 840 sl, GE FANUC 0i and GE FANUC 30i guarantee excellent control and programming comfort.
Machines meet your expectations in terms of ease of use, including integrated workshop programming.
