FOCUS ON PUNCHING
The MP 4020 can be controlled via CAD data or the control panel directly on the system . The operator can quickly adjust programs and make corrections .

“ Ease of use was very important for us ,” said Hungerbühler . “ Multiple options mean that I have the opportunity to adjust everything down to the last detail , but the risk of disruptions also increases .”
A flexible format
The MP 4020 has been at HMH Hungerbühler in Arnegg since the beginning of 2020 . The company uses the machine for different jobs . These include the addition of welding “ bosses ” to super-sized , stainlesssteel sheets for pool floors ( ensuring slip resistance in the pool ) and the production of newly developed lightweight safety components for mobile homes .
This process takes place in a single clamping with one automatic tool change . First , the MP 4020 punches 200 shapes ( four slots arranged in a square ) from above into a largeformat , 1mm-thick aluminium sheet . In the second step , another tool presses against the previously introduced moulds from below , creating 200 high deformations .
“ In a further process , two of these sheets are used to create a light and very stable component ,” explained Hungerbühler .
“ At first I was amazed at what was actually possible with the system ,” added Hungerbühler , describing his experiences with the MP 4020 . “ We now have a punching machine in the hall with much greater capability . For example , processing 6m metal sheets without repositioning them is no longer a problem and we now have more flexibility in production .”
If a part to be manufactured does not have too many complex contours , punching is usually a more economical alternative to laser cutting .
Close collaboration
“ The close , open and honest collaboration with Boschert during development was also a lot of fun and really impressed me ," confirmed Hungerbühler .
Roser agreed , adding : " There was never a bad word the entire time , even when there were delays in the project for example due to delivery bottlenecks or the COVID-19 pandemic .”
“ One of our proudest achievements over the last few years was the development of the 4020 . It is the only punching machine in the world able to punch 4 x 2m without repositioning . This helps customers who want to punch large sheets ,” Boschert told ISMR last year .
“ Many customers would like to process all
About Boschert GmbH & Co KG
Boschert GmbH & Co KG celebrated its 75th anniversary in 2021 . Founded in 1946 as a small workshop for the textile industry , today it builds a wide range of sheet-metalworking equipment . This includes notching ; punching ; small and mid-sized press-brake bending systems ; plasma ; laser ; combined punching / plasma / fibre laser and copper processing machines . It also builds special machines to meet specific customer requirements .
Based in Lörrach ( near Freiburg , Germany ), Boschert employs 120 members of staff and has a production and assembly area of some 8,000 square metres . There are a further 700 square metres of office space , as well as a presentation and demonstration centre .
their metal sheets in one working cycle so the machine features a new tooling system with 12 stations for TRUMPF tooling . With stepless indexable tools , it offers a total of max . 96 tools which is more than enough for most sheetmetalworking operations . It is possible to preadjust tooling for different sheets or for partial sheets . This reduces non-productive downtime to a minimum and enables longer machine useful life ,” it continued .
Development on the MP 4020 , in the meantime , still continues apace . Additional systems have been installed by other users , leading to new input and customer feedback for Boschert . Meanwhile , the first combined FiberLaser / punching MPL 4020 is in operation with another customer . n
