Professional tool presetting pays off
– right from the first machine
The still young company "HE-Zerspanungstechnik" is a sub-contractor for single parts, assemblies, highly customized prototypes and small series.
Visitors to the small company based in Brandenburg/Germany, which was only founded in 2011, are faced with a state-of-the-art 5-axis processing center and a ZOLLER tool presetting and measuring machine. During investment into the second machine, a ZOLLER tool presetting and measuring machine was also part of the investment – "because it pays off", so owner René Dobberke. "We have reduced set-up times by between 50 to 60%!" Before the ZOLLER machine was available, set-up was performed manually using a dynamometer and sensor - an elaborate process with inaccurate results and a machine which was idle.
A high rate of tool exchange is required for building prototypes - currently some 60-70 tools of all types are used every day. Some ten to twenty tools are required per workpiece and machine - setting all this up manually takes considerable time. The parts are milled from a single piece, that means set-up can only be performed once a part is completed.
Totally different with a tool presetting and measuring machine. While the machine is still producing product, the next order can be fully prepared. "Previously, setting-up took three hours per order - now we are down to 45 minutes!", so René Dobberke. "Furthermore, the tools are now set to an accuracy of plus/minus 2 µm, with high repeatability. This has a major effect on the increased quality of the manufactured parts.
The conclusion - investment into professional tool presetting and measuring technology also pays for absolute specialists and small companies at home in market niches - right from the start.
