Maxed out

Developed to provide a cost-effective solution to repetitive operations, the productive Maxima series has 19 tool positions and seven axes.

The Maxima range for complex components complements the lower specification Optima range. It offers a 3-axis upper slide with a maximum of eight fixed tools or a combination of four fixed tools and three driven tools. This combines with a 2-axis turret to enable two tools to work simultaneously on a component in the main spindle

In addition, the Maxima range has a turret at the middle of the work envelope that offers four driven tool positions, one of which is used for the pick-off spindle. To enhance productivity, the turret is bi-directional via the shortest route which shaves vital seconds off production cycles. The sub-spindle operates simultaneously with the main spindle to allow three tools to work at once – further enhancing productivity.

The motorised pick-off spindle in the turret holds the machined part and is synchronised with the main spindle to give pipless part-off. Once the pick-off spindle collects the part from the main spindle, the component is then machined with the four tool second operation station that is mounted at the opposite end of the machine bed from the main spindle. The back working stations are available with live tooling configurations.

The Maxima range is available in 36mm, 42mm, 60mm and 65mm diameter capacity ranges, equipped with drill breakage detection, pick-off component expulsion detection and tool life monitoring for lights out production. The ability to produce large batches on a lights-out basis is enhanced by a magazine bar feed that reduces the need for operator intervention.

The build quality of the Unamuno Maxima range is guaranteed with all axes using high speed servo motors and precision ballscrews with absolute encoder positioning. The powerful motor spindles from 7.5kW to15.5kW dependent upon machine size have high speed acceleration and optional C-axis positioning or full C-axis interpolation with the upper slide for complex machining.

With a focus on ease of use, Unamuno has developed a touchscreen control. Suited to users accustomed to ISO programming, the Mitsubishi CNC control ensures that no specialised programming knowledge is needed as the system uses intuitive programming techniques to program even the most complex of parts. The ease of use is combined with additional features such as nano-control technology for high quality and precision machining.
