SCHUNK modules are installed at a number of produc\u00adtion loca\u00adtions at Neher. For the produc\u00adtion of customized special tools for the auto\u00admo\u00adtive industry, the company in Ostrach-Einhart uses various tool\u00adholders, chuck jaws, lathe chucks and vises from SCHUNK.<\/p>\n

As a top performer, Neher needs reli\u00adable produc\u00adtion compo\u00adnents to meet the high customer require\u00adments for both tool clamping and work\u00adpiece clamping. \u201cWe need top quality in any case,\u201d says Tobias Niess, Devel\u00adoper at Neher. All the more so when it comes to partic\u00adu\u00adlarly demanding parts produc\u00adtion, such as the addi\u00adtive manu\u00adfac\u00adturing of highly specific tools made of metal. This is where the VERO\u2011S NSE-HT mini 88\u201320 quick-change pallet system comes into focus. The clamping system for use in high-temper\u00ada\u00adture appli\u00adca\u00adtions remains unaf\u00adfected by the finest dusts, abra\u00adsive mate\u00adrials and even contin\u00aduous immer\u00adsion baths.<\/p>\n

There are chal\u00adlenges beyond what clamping systems need to with\u00adstand in everyday, conven\u00adtional machining processes. \u201cWe can\u2019t imagine our produc\u00adtion processes without this quick-change pallet system,\u201d says Tobias Niess. And he knows exactly what he\u2019s talking about.<\/p>\n

Quick-change pallet system as the basis for preci\u00adsion<\/h2>\n

He and his team oversee 3D metal printing at the company. For this purpose, the company purchased the modern Lasertec 30 Dual SLM from DMG Mori for gener\u00ada\u00adtive manu\u00adfac\u00adturing by selec\u00adtive laser melting (SLM). This \u201c3D printer\u201d can be used to gener\u00ada\u00adtively manu\u00adfac\u00adture highly complex compo\u00adnents with differ\u00aden\u00adti\u00adated func\u00adtional inte\u00adgra\u00adtion in a powder bed heated up to 200 degrees Celsius. This so-called hybrid printing process, melting work\u00adpieces onto prefab\u00adri\u00adcated compo\u00adnents, is also achieved at Neher. In this process, geomet\u00adri\u00adcally simple work\u00adpiece compo\u00adnents are manu\u00adfac\u00adtured conven\u00adtion\u00adally, and the complex geome\u00adtries are then addi\u00adtively \u201cprinted\u201d onto the hybrid blank. For this purpose, the clamping pins of the quick-change pallet system are mounted directly on the hybrid blank.<\/p>\n

This approach utilizes the advan\u00adtages of both processes and signif\u00adi\u00adcantly reduces manu\u00adfac\u00adturing costs. The runtime of the 3D printer is short\u00adened, meaning it can move on to the next job faster.<\/p>\n

A prereq\u00adui\u00adsite for the precise and effi\u00adcient produc\u00adtion of these kinds of work\u00adpieces is the absolutely precise clamping of the substrate plate on which the product is addi\u00adtively built in the machine room. This is where the VERO\u2011S NSE-HT mini 88\u201320, which SCHUNK designed and laid out specif\u00adi\u00adcally for appli\u00adca\u00adtions in 3D metal printing, stands out.<\/p>\n

Heat resis\u00adtant and perfect for 3D metal printing<\/h2>\n

\u201cThis clamping module is special,\u201d says Devel\u00adoper Benjamin Hirz. \u201cWhile conven\u00adtional quick-change pallet systems can be used up to 60 degrees Celsius, this clamping system with\u00adstands the high temper\u00ada\u00adtures of the steel powder melting process.\u201d \u201cWithout the VERO\u2011S NSE-HT mini 88\u201320, we would not be able to imple\u00adment the ther\u00admally demanding manu\u00adfac\u00adturing process. It always reli\u00adably guar\u00adan\u00adtees us the fixed posi\u00adtion on the machine table side,\u201d explains Tobias Niess.<\/p>\n

At Neher, four VERO\u2011S NSE-HT mini 88\u201320 modules are used, as well as a VERO\u2011S NE-HT mini 36 quick-change pallet unit in the center. The quick-change pallet unit defines the thermal zero point for large substrate plates via a centric clamping pin. The clamping itself takes place simul\u00adta\u00adne\u00adously via the remaining four clamping pins. An inte\u00adgrated spring assembly secures the clamping perma\u00adnently and is self-locking\u2013 air is only required for the opening process.<\/p>\n

Sealing concept keeps out dust and abra\u00adsive mate\u00adrials<\/h2>\n

The second major chal\u00adlenge for the clamping system is that it is perma\u00adnently exposed to the highly abra\u00adsive mate\u00adrials. But the SCHUNK sealing concept makes it possible to resist the finest metal dusts that pene\u00adtrate even the tiniest crevices.<\/p>\n

\u201cOur sealing concept is so reli\u00adable that the clamping system is even suit\u00adable for immer\u00adsion baths,\u201d confirms Benjamin Hirz. \u201cUnder all of these envi\u00adron\u00admental condi\u00adtions, a perma\u00adnently high force is main\u00adtained on the clamping slide, which ensures absolute process reli\u00ada\u00adbility. Even if fine metal powder gets into the cutting area, the clamping slides do not get blocked. The module clamps reli\u00adably.\u201d<\/p>\n

Long life span<\/h2>\n

One single VERO\u2011S NSE-HT mini 88\u201320 has been running on the 3D metal printer at Neher for three years. \u201cAbsolutely reli\u00adable and trouble-free and one hundred percent precise,\u201d Tobias Niess empha\u00adsizes. Despite the long machining times of seven to ten hours in 3D metal produc\u00adtion, SCHUNK states that the service life of a quick-change pallet system used in this way is approx\u00adi\u00admately ten years.<\/span><\/p>\n

Special tools manu\u00adfac\u00adturer<\/h4>\n

Among other things, Neher manu\u00adfac\u00adtures stan\u00addard and special tools as well as compo\u00adnents for a wide variety of appli\u00adca\u00adtions, including power\u00adtrain modules for the auto\u00admo\u00adtive industry.<\/p>\n

In addi\u00adtion to modern CNC-controlled turning and milling machining centers, several 3D metal printers as well as corre\u00adsponding measuring tech\u00adnology have been in use for several years, which is why the company can produce a wide variety of customized compo\u00adnents in light\u00adweight struc\u00adture with func\u00adtional inte\u00adgra\u00adtion.<\/p>\n

The one-man oper\u00ada\u00adtion founded in Ostrach in 1990 as Neher Diamantwerkzeuge has devel\u00adoped into a state-of-the-art company that currently has around one hundred employees. Since June 2021, Neher has expanded its busi\u00adness field to include fixture construc\u00adtion, jig construc\u00adtion and measure\u00adment tech\u00adnology.<\/p>\n
