F<\/span>or a long time now, rims have been much more than just wheels, choosing the right rims is para\u00admount for many car enthu\u00adsi\u00adasts. The person\u00adality of modern car owners is not only reflected in the choice of model, but also in the indi\u00advidual design of the wheels. Whether pink or gold, small or large, simple or eye-catching \u2013 there are no limits to your imag\u00adi\u00adna\u00adtion.<\/p>\n

ROC Fertigung24 in Freuden\u00adstadt has been turning the dreams of wheel enthu\u00adsi\u00adasts into reality since 2017. The mate\u00adrial used is mainly aluminum, at the indus\u00adtrial estate on the B294 around 30 tons are sold per month. This results in forged wheels of up to 25 inches in diam\u00adeter. All this variety would not be possible without the exten\u00adsive range of tool\u00adholders from SCHUNK.<\/p>\n

ROC Fertigung24 manu\u00adfac\u00adtures car rims according to indi\u00advidual customer require\u00adments. For this, the company relies on tool\u00adholders from SCHUNK.<\/figcaption><\/figure>\n

Flaw\u00adless rims due to sturdy tools<\/h4>\n

\u201cOur parts are first turned and then milled,\u201d explains Managing Director Lukas Betz. The basic shape is first turned from a blank on a hori\u00adzontal CNC lathe. This is then machined on 5\u2011axis milling machines from DMG. In doing so, ROC Fertigung24 relies on a consid\u00ader\u00adable range of milling cutters in a wide variety of sizes. By the end, the finished rims include some highly deli\u00adcate details, all of which also have to have a flaw\u00adless surface finish because the rims are painted.<\/p>\n

This means that nothing can go wrong during milling. The require\u00adments for tool holders and tools are high. \u201cThe tool has to be stable for us and have a certain unclamping length. However, long cantilevers are sensi\u00adtive to vibra\u00adtions,\u201d explains Betz. \u201cThat\u2019s why you need absorbent holding systems. This is where SCHUNK\u2019s hydraulic expan\u00adsion tool\u00adholders are the right choice because they dampen the vibra\u00adtions.\u201d<\/p>\n

ROC Fertigung24 share\u00adholder Tobias Haug concurs: \u201cThere is nothing better for us.\u201d With SCHUNK, we have found a partner at an equal level, which is also avail\u00adable for consulting. At the begin\u00adning of the collab\u00ado\u00adra\u00adtion, for example, it was not clear whether heat shrinking tech\u00adnology might be the better choice for tool\u00adholders instead of hydraulic expan\u00adsion tech\u00adnology. We conducted exper\u00adi\u00adments together.<\/p>\n

It quickly became clear that, compared to heat shrinking, use of hydro-expan\u00adsion and polygon clamping tech\u00adnology offered a better energy balance on the one hand, and better processing results on the other. An addi\u00adtional posi\u00adtive effect was that the tension could be applied more quickly by means of mechan\u00adical action. Thus, the numerous tool changes were not only more sustain\u00adable, but also more effi\u00adcient.<\/p>\n

Produc\u00adtion in just three days<\/h4>\n

Because speed is one of the core topics at ROC Fertigung24: \u201cMany of our customers assemble their rims indi\u00advid\u00adu\u00adally via our online config\u00adu\u00adrator using their CAD data,\u201d says Mr Betz. \u201cThen, when an order comes in, we get it ready within three days.\u201d This speed is also expected from SCHUNK when some\u00adthing doesn\u2019t fit. \u201cWe can count on fast service there,\u201d Betz said.<\/p>\n

\u201cOur total tooling concept comes into its own here,\u201d stresses Hermann Winterer, the SCHUNK tech\u00adnical consul\u00adtant in charge, glancing around the machine shop of the rim manu\u00adfac\u00adturer. Betz explains, \u201cWe have every\u00adthing here from 700 size jaw chucks to all tool holders, TENDO E compact, TENDO P, TENDO LSS, and a wide variety of inter\u00adme\u00addiate bush\u00adings increasing flex\u00adi\u00adbility.\u201d The clamping tech\u00adnology compo\u00adnents are used in six DMG Mori DMU75 monoblock 5\u2011axis milling machines, among others.<\/p>\n

Depending on how much or little removal is required, ROC Fertigung24 moves at both ends of the spec\u00adtrum when it comes to tool\u00adholders, for example with the small TRIBOS Mini polygon tool\u00adholder for ultra-fine machining or the slim TENDO Slim 4ax for machining close to inter\u00adfer\u00adence contours. Other SCHUNK clamping tech\u00adnolo\u00adgies are also used at ROC, such as the SINO\u2011R expan\u00adsion tool\u00adholder and the extremely slim TRIBOS\u2011S polyg\u00adonal tool\u00adholder. Mechan\u00adical tool\u00adholders such as ER collet chucks and WELDON arbors complete the manu\u00adfac\u00adturing require\u00adments.<\/p>\n

The right tools for the job<\/h4>\n

In the case of the TRIBOS Mini, the outstanding dynamic runout of < 0.003 mm is partic\u00adu\u00adlarly impor\u00adtant for ROC Fertigung24 \u2014 after all, the noble rims demand the maximum surface quality. Micro-blowouts on the tool cutting edge is avoided by the excel\u00adlent vibra\u00adtion damping of the TRIBOS polyg\u00adonal clamping system.<\/p>\n

\u201eWith SCHUNK we can rely on quick service.\u201c<\/p>\n

With the TENDO Slim 4ax, ROC Fertigung24 some\u00adtimes machines very deep in the Z axis. Rim experts benefit from the fact that it is the only tool\u00adholder in its class with a heat-shrinking contour according to DIN 69882\u20138. Its robust base body prevents lateral deflec\u00adtion during the cutting process. The enor\u00admous clamping pres\u00adsure inherent in all SCHUNK TENDO hydraulic expan\u00adsion tool\u00adholders also enables ROC to machine job after job without compro\u00admising reli\u00adable torque trans\u00admis\u00adsion. The enor\u00admous clamping pres\u00adsure creates a displace\u00adment of oil, grease or grease residue into the dirt groove and the clamping surface remains dry.<\/p>\n

When it comes to clamping, the company still sees poten\u00adtial for joint devel\u00adop\u00adment in the future. Due to the large over\u00adhang of the tool and the depth of the rims to be machined, the clamping table has to be very narrow. At the same time, however, it must also provide perfect support at high rota\u00adtion and centrifugal forces. \u201cUnfor\u00adtu\u00adnately, physics restricts us here,\u201d says Mr Winterer. So far ROC Fertigung24 has relied on a home-grown solu\u00adtion, but is looking to close coop\u00ader\u00ada\u00adtion with SCHUNK. \u201cOf course, it would be better if there was some\u00adthing from SCHUNK,\u201d says Managing Director Haug. \u201cWe\u2019re on it,\u201d assures Mr Winterer.<\/p>\n
