An eye on quality and efficiency
The Bavarian company , Rösler Oberflächentechnik GmbH , supplied the wire belt blasting system for descaling , paint stripping , derusting , roughening and cleaning the metal parts . This delivers all-round reproducible blasting results .
The system for deburring and edge rounding ( the EdgeBreaker ® 9000 LINE ) was manufactured by ARKU Maschinenbau GmbH , based in Baden-Baden , Germany .
“ This is designed for efficient slag removal , deburring and rounding of metal parts in one single pass through the machine . Compared to single-sided machines where parts pass through several times , this system cuts [ processing ] time by fifty per cent and increases productivity ,” confirmed ARKU .
“ Liebherr consciously chose European manufacturers not just because of the quality of their products , but also because of comprehensive customer service . This strategic decision reflects Liebherr ’ s commitment to ensuring the highest standards of quality and operational efficiency ,” it added .
The partners voiced their enthusiasm during a tour of the finished installation .
“ We are pleased that our system for slag removal , deburring and edge rounding offers a suitable solution for economical line production that meets the highest quality standards ,” said Stefan Sauter , International Sales , ARKU Maschinenbau GmbH .
Vasili Schaermann , Global Sales Expert , Rösler Oberflächentechnik GmbH , added , “ Our blasting system fits perfectly into [ Liebherr ’ s ] production process and delivers impressive results .”
The shortage of skilled labour was also a key point of discussion during the tour .
“ At a time when skilled labour is in short supply , our robot technology can be a crucial component in closing this gap and making work steps more efficient ,” added Markus Lindörfer , Automation Specialist , Teqram B . V .
Liebherr was finding it increasingly difficult to recruit qualified employees for this area . The deburring line was planned over an extended period , with the reduced need for labour considered early in the process . Ever since implementation of the machines , employees have been able to take on other roles at the production site in Biberach .
This project reflects Liebherr ’ s investment in its Biberach site despite difficult economic conditions . The three manufacturers have already worked together several times in various ways , which has had a positive impact on the project outcome at Liebherr .
“ Communication between the companies involved has been outstanding . Everyone was considerate [ and accommodating ] so we were able to achieve progress quickly ,” concluded Robert Piesche . The system went into operation in May this year and has been running ever since . n
