Focus on precision and process reliability<\/h2>\n

In the port, where containers weighing tonnes are moved by gigantic cranes, everything depends on precision: gears mesh, shafts drive and every single component has to withstand the highest loads. But as impressive as these machines look, precision on a small scale is just as crucial.<\/p>\n

\u201cOur machines process workpieces ranging in size from 20 millimeters to 1400 millimeters \u2013 theres \u2018a lot of expertise behind them, \u201d explains Philipp H\u00fcsch, who is responsible for tool purchasing and processes at Karl Georg. \u201cHowever, we have faced considerable challenges in the past, especially when it comes to threads.\u201d<\/p>\n

The production of blind hole threads in drive and idler shafts, which are later shrunk into the crane running gears, is particularly challenging. Here, thread depths of up to 70 millimeters have to be produced with thread cutters \u2013 unusually deep for an M16 thread. This depth regularly led to problems with chip removal.<\/p>\n

\u201cIn the past, we often lost tool life because chips got stuck in the blind hole. Often the tool even broke off and could no longer be removed from the hole,\u201d recalls H\u00fcsch. \u201cThe entire component became scrap.\u201d Such incidents are particularly annoying when they occur in an automated machining process: the entire process comes to a standstill, machines have to be stopped and valuable time is lost. \u201cI have to be able to rely on the process,\u201d emphasises H\u00fcsch.<\/p>\n

Until now, Karl Georg had to rely on special tools for such deep threads, but here G\u00fchring field service consultant Marcel Horn had a different idea: the new modular fluteless tap<\/a>. \u201cThe length here is perfect and we don\u2019t have to work with any extensions or special concepts, \u201dexplains Marcel Horn. Another advantage of the G\u00fchring system is the connection between the HSS tool shank and the carbide thread head. The AlCrN coating of the thread head ensures high wear resistance, while the repeated use of the shank drastically reduces the costs per component. In addition to the practical benefits, the process change also offers improved quality: fluteless tapping produces particularly strong threads that can easily withstand the high loads in crane system operation. For a company like Karl Georg, which depends on reliability and precision, this is a decisive competitive advantage.<\/p>\n

Safe and fast <\/span>
\nFluteless forming instead of tapping<\/span><\/h2>\n

\u201cThat was a real game changer,\u201d reports Philipp H\u00fcsch. In contrast to taps and milling cutters, where the chips have to be removed from the blind hole, no chips are produced during fluteless tapping. \u201cThis not only makes the entire process safer, but also faster,\u201d says H\u00fcsch. The modularity of the mould is particularly impressive. \u201cThe shank is retained and only the tool head is replaced when it wears out. This saves costs and simplifies replacement considerably,\u201d explains H\u00fcsch.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ make_equal=”on” _builder_version=”4.27.4″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_column type=”1_3″ module_class=”gue-quotebox-3col-column” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_blurb alt=”Philipp Kunze” _builder_version=”4.27.6″ _module_preset=”default” background_image=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/02\/GUE_website-pikto_zitat.svg” global_colors_info=”{}”]\u201cThis not only makes the entire process safer, but also faster.\u201d<\/p>\n

For Karl Georg, this means no more customised solutions, no complex adjustments, but an efficient and trouble-free process. \u201cWith this tool, we have not only tripled tool life from 20 to 60 minutes, but also significantly reduced machining times, as redrilling for chip removal is no longer necessary.\u201d<\/p>\n
