Mill Features Integrated Workpiece Changer
August 1, 2015
KERN Microtechnik, a machine manufacturer based in Bavaria, has upgraded its KERN Micro to include an integrated workpiece changer. The workpiece changer and the tool changer are both combined and integrated in a tool cabinet in the machine.
"Workpiece changers are usually known to be outside of the machines they supply with workpieces, which require additional space, transportation systems and interface between the machine and the changer," said a company spokesperson. "KERN decided to simplify these processes and make better use of the space inside the Micro. The new tool cabinet of the Micro contains the tool changer and the workpiece changer. Usually the tool changer of the machine can hold more than 180 tools, ready to be used whenever necessary. However, most automation processes do not require 186 tools. KERN Micro gives the option to charge the cabinet with fewer tools and use the open space for up to 30 workpieces, so no additional space for an external workpiece changer is required." Charged with 30 workpieces, the Micro can still hold 90 tools. It is possible to extend the capacity with an additional external workpiece changer.
There is only one guiding system that takes tools and workpieces into and out of the machine, saving space and cost for an additional workpiece transportation system. "One advantage is that almost no additional components are required," said the spokesperson. "Another advantage of the tool cabinet is the well-designed integration. Also the software of the tool cabinet is fully integrated and no additional interfaces are needed. The whole machine including the tool cabinet can be run with only one software and brings an end to the times where different software systems had to be merged."
When the workpiece is changed the chuck is turned on a 90° angle and thus all chips from the milling process are removed. This technology prevents inaccuracies caused by chips of the former workpiece being left behind on the chuck and being clamped in onto the new workpiece.
"The accuracy of the Micro and the reliability of the workpiece changing process provide the basis of a stable machining process," said the spokesperson.
