Record breaking: Chip-to-chip time <0.5 seconds!

In developing the Bumotec s100multi, Bumotec is aiming to revolutionise series production of small precision parts.

+ 250% higher productivity with the same amount of floor space
+ 20% higher energy efficiency


With its eight high-speed spindles (60,000 rpm), the s100multi transfer machine accelerates (3g: 29.43 m/s2) and machines extremely quickly thanks to the linear motors fitted in all axes, achieving a record-breaking chip-to-chip time of 0.5 seconds. What’s more, the new machine operates without any hydraulic components.

There is a growing need within the industry for flexible, ergonomic and easy-to-programme machine tools that deliver a high level of productivity and dynamism when milling from batch size 1 up to series production. Machine tools such as these circumvent the disadvantages associated with having multiple operations on a set of single-spindle machines and the inflexibility of conventional transfer machines.

The new machine has been developed with exactly these requests in mind. Thanks to the minimal amount of space the machine requires and the multiple tool magazines that can hold up to 144 tools, the dynamic machining centre is a key solution for manufacturers needing to quickly produce highly accurate, ultra-precision parts up to a maximum size of 80×80×80 mm. Typical applications include components for the watch, computer and electronics industry. Customer trials are showing that drawing on this machine concept can deliver a 250% increase in productivity, all while maintaining the same amount of
floor space.

“The Bumotec s100multi offers the ideal combination of a high level of productivity, a high level of precision and improved flexibility”. In each case, two milling spindles work simultaneously to achieve an extremely high level of precision within very short cycle times. The exceptional dynamism and interpolation performance is achieved by drawing on the latest technology and specially designed, optimised mechanical elements. In bringing about this development, particular attention was paid to boosting energy efficiency.

The shorter cycle times and measures such as energy recovery highlight the efforts made as part of the Blue Competence Initiative.

Working together with specialists, special attention was given to achieving an ergonomic design that allows the user to gain easy access to the workpiece.
