These machines provide a combination of one single upper slide with a three-axis tool combs and a two-axis lower slide turret system. The tool combs provide extremely fast tool changes, while the Y axis provides a wide range of simultaneous turning and milling operations on both the main spindle and sub-spindle.
The upper slide incorporates a B axis (rotation axis around the Y axis). This allows the cutting tool to tilt and rotate, facilitating machining of inclined and complex surfaces.
The sub-spindle integrated into the MAXIMA 7B has two axes (X-3, Z-3) for conducting secondary, more complex machining operations. This axis configuration allows for "superimposition" operations.
Has X-1, Z-1, Y-1 and B axes, with 3 rows of tools, for a total of 15 tool positions, 9 of which are driven and up to a total of 30 tools (using double tools).
Provides for up to 24 tools (12 for main spindle and 12 for sub-spindle), X-2 and Z-2 movement axes, on a turret with one single motor for tool changing and transmission to driven tools. Tools can be fixed interior/exterior or axial/radial driven.
Has two X-3 and Z-3 axes. With the superimposition operation, 3 operations can be conducted simultaneously.
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.
