The machine provides a 3-axis front slide with turret and a 3-axis rear slide and a sub-spindle.
The OPTIMA 8 machine has a sub-spindle with 2 axes (X-2, Z-2).
The system permits extremely fast tool position changes and simultaneous execution of several operations on both the main spindle and the sub-spindle, using either the turret or the tool comb.
The slide configuration of this machine model allows one slide to work on the sub-spindle independently of operations performed on the main spindle by the other slide. Additionally, it allows both slides to work simultaneously on both the spindle and the sub-spindle, using the superimposition function.
It features X-3, Y-3, and Z-e axes with a turret with no disc displacement during indexing, driven by a servo motor, with 24 stations for fixed or driven tools, with 12 for the main spindle and 12 for the sub-spindle.
It has X-1, Z-1, and Y-1 axes, as well as up 6 positions for exterior turning tools working on the main spindle 8 and positions for tools working on the sub-spindle.
Driven tooling system on both turret and tool comb.
Has two X-2 and Z-2 axes.
The "superimposition" feature of the control provides for simultaneously cutting with 3 tools to improve production cycles. With both the turret and the tool comb working on the main spindle, the turret can also work on the sub-spindle.
With the manual pulse generator, both the upper slide and the sub-spindle can be moved forward and backward with the programme. This feature considerably reduces machine fine-tuning times.
