FOCUS ON SURFACE FINISHING
After deburring , there is a clear difference to the unprocessed material , as Stefan Sauter , Sales , ARKU , explained to Autz + Herrmann ’ s technical managing director , Florian Friedrich .
“ The deburring machine is especially flexible because of its quick-change system for tools . This reduces set-up times , a key factor when it comes to small batch sizes . Using a vacuum table as a support surface , the EdgeBreaker ® 6000 can also hold smaller parts in place during processing ,” added ARKU .
The reworking process
Daniel Gabriel , Autz + Herrmann ’ s head of punch-laser processing and programming , is highly impressed with the new deburring machine .
“ We used to need an employee to handle manual deburring , but now it is incredibly fast ,” he explained . “ Laser cutting makes burr formation more likely as the material thickness increases . Sooner or later , you must rework the material . It is more ergonomic and more costeffective with the EdgeBreaker ® than by hand .”
He continued : “ We have a new medical technology product made of 5mm-thick aluminium ( 0.19 inches ). This is difficult to laser-cut and relatively delicate . However , the EdgeBreaker ® processes it very well and , afterwards , the low-quality side ends up looking better than the good side .”
When manufacturing other products , such as flanges for its customer Rotoclear , employees had to closely examine the quality of the laser cutting results .
“ However , since we began deburring , we can rely on consistent high-quality results ,” Gabriel explained . The new deburring machine also proved its value for the manufacturer far earlier in the process .
“ During sales discussions , we no longer need to ask customers whether edge-
Carefully processed sheet edges are essential for subsequent processes such as robot welding .
rounding is truly necessary . We simply have this capability in our portfolio , which makes discussing this issue far easier ,” Friedrich reported .
The specialists at Autz + Herrmann also looked at various other deburring machines . However , several aspects distinguished ARKU ’ s offer , including the vacuum suction principle for securing parts . However , one particular recommendation made all the difference ….
“ TRUMPF included ARKU as a partner for deburring and levelling at its digitalised factory in Ditzingen . This impressed us because very few companies have succeeded in achieving this ,” explained Friedrich .
“ We also carried out deburring trials together at our Levelling and Deburring Centre with successful results ,” added Stefan Sauter , Sales , ARKU .
User-friendly operation
However , ease of operation was eventually the deciding factor .
“ The user interface and parameterised programming are effortless to understand and utilise . Individual programs can also be saved ,” said Florian Friedrich .
“ The controls are self-explanatory ,” added Gabriel , saying : “ Everyone is familiar with the play and stop buttons . The material thickness and infeed can vary , but they are very easy to configure once you understand how .”
The EdgeBreaker ® 6000 at Autz + Herrmann is also equipped with the ARKU Wizard . This intelligent software connects the workpiece , tool and machine data . This means that operators just have to enter the part properties and the desired processing result ; the wizard handles the rest . With the help of the
