MAXIMA 8

The MAXIMA 8 machine was designed for the most productive and effective cost solution for the increasingly demanding market for bar- or chuck-fed turned components, with one single setup. Production of simple or complex components is straightforward with the MAXIMA 8's multi-tool and multi-tasking capabilities.

The machine provides two upper slides with tool combs, a three-axis left-hand slide for work on the main spindle and a two-axis right-hand slide for work on the sub-spindle.

The sub-spindle incorporates a Z axis which, in combination with the axes of the right-hand upper slide, allows a wider range of secondary operations to be executed.

The slide system with tool combs provide excellent versatility and 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.

UNAMUNO MAXIMA 8 has the slide system with tool combs that performs 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.

AXIS CONFIGURATION
Axis configuration of the UNAMUNO CNC MAXIMA 8

LEFT-HAND UPPER SLIDE

The left-hand upper slide with tool comb has X-1, Z-1, and Y-1 axes, as well as 11 tool positions, 5 fixed internal or external tools and up to 6 fixed or driven tools to work with the main spindle.

RIGHT-HAND UPPER SLIDE

The right-hand upper slide with tool comb has X-2 and Y-2 axes, as well as 11 tool positions, 5 fixed internal or external tools and up to 6 fixed (or optional driven) tools to work with the sub-spindle (Z-2 axis on sub-spindle slide).

SUB-SPINDLE SLIDE

Z-2 axis.

CNC SYSTEM
CNC system of the UNAMUNO CNC MAXIMA 8
  • Mitsubishi M80V nano CNC control system, extremely fast and powerful control with 10.4" touchscreen (optional 15").
  • Part programme test.

    • 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.

    Additional standard control features:

    • USB connection to PC.
    • Electronic collision detection system.
    • Automatic shut-down system.
    • Tool load display.
    • "Tool life" management.
    • Connection to peripheral devices and equipment with a range of fieldbus networks, including CC-Link®, PROFIBUS® DP, and EtherNet/IP™.
    • Remote connection for maintenance.
    • Alarm notification system with EMAIL messages.
    • Custom customer screen integration.
