Ua hōʻole ka mea hana Kelemania ʻo Funkenerosion i nā kauoha ma mua no ka mea ʻaʻole i loaʻa i kā lākou mīkini EDM uea kēia mau mamao huakaʻi. "He ʻoi aku kā mākou ma mua o 500 mau mea kūʻai aku ikaika, a inā ʻaʻole hiki iā ʻoe ke lawe i nā kauoha no ka mea ʻaʻole ʻae ka nui o ka mīkini, he mea paʻakikī maoli nō ia," wahi a ka luna hoʻokele ʻo Markus Langenbacher.
Eia nō naʻe, ua kupaianaha loa ka pāka mīkini me nā mīkini Sodick EDM, hoʻokahi ALC400G, hoʻokahi SLC400G, hoʻokahi AG400L a me hoʻokahi AQ750LH. ʻAʻole i hoʻopilikia iki nā lawelawe Wire EDM i ka hana ʻaelike i kekahi o nā makemake o ka mea kūʻai aku, koe wale nō i loko o ka pae XXL pono lākou e hōʻole i nā kauoha i kēlā me kēia manawa.
"Ua hoʻohana mākou i ka EDM uea mai ka hoʻomaka ʻana, a ma hope koke iho ua hoʻohui pū mākou i ka make e piholo ana," wahi a Jörg Romen, nāna ke kuleana o ka ʻoihana pala uea. Ke hoʻomaka ka piʻi ʻana o nā kauoha ʻaelike, pono e kūʻai ʻia nā EDM hou. Ua hāʻule ke koho iā Sodick. "Ua hāʻawi mai ʻo Sodick iā mākou i kahi hāʻawi hoihoi no nā mīkini ʻekolu, ka mea i hōʻoiaʻiʻo iā mākou i ko lākou maikaʻi a me ka pololei," wahi a Jörg Roming. ʻO nā mīkini mua ʻekolu, hoʻokahi wale nō e hana nei; ua hoʻololi ʻia ʻelua i ka hala ʻana o ka manawa. "Ua hana mākou i ka nui o ka alumini, kahi i kau ai i ke kaomi nui ma ka mīkini.

Ma ke ʻano he mea hana ʻaelike, ʻo bes Funkenerosion ke poʻo i nā kaʻina hana āpau mai EDM a i ka ʻeli ʻana a me ka ʻino uea. Hiki i nā mea kūʻai aku ke kūʻai aku i nā mea pono a me nā mea hoʻopau pololei mai ka hui ma Fluorn-Winzeln, e like me ka ʻeli ʻana a me nā electrodes threading ma aneane nā lōʻihi a me nā diameters āpau. ʻO nā mea kūʻai aku koʻikoʻi e komo pū me nā mea hana hana, nā mea hana mold, nā ʻoihana ʻenehana lapaʻau a me ka ʻoihana aerospace. "ʻO nā mea hoʻopau kekahi o kā mākou mau pou nui a loaʻa iā mākou kahi ākea o nā waihona i loko o ka waihona, no laila hiki iā mākou ke hōʻoia mau i nā manawa hoʻouna pōkole", hōʻoiaʻiʻo ʻo Markus Langenbacher.
Ua hoʻāʻo ʻia ka hana o nā mea electrode ma ka ʻoihana hoʻāʻo e hōʻoia i nā mea kūʻai aku i nā hopena maikaʻi loa i ka wā o ke kaʻina hana ʻeli EDM; ʻo ke ʻano o kēia ʻano hana ʻaʻole e hoʻopilikia ka ʻoihana i nā koi kūikawā a ka mea kūʻai aku. I kēia manawa koke nei, ua kauoha kekahi mea kūʻai aku i 20,000 mau electrodes mai ka ʻoihana ma hope o kahi hoʻāʻo holomua.
I ka hoʻoholo ʻana o ka mea hoʻokumu o ka ʻoihana e hoʻomaha i ka hoʻomaka o 2021, ua pono kahi luna hoʻokele hou. I kēia kauwela, ua lawe ʻo Markus Langenbacher i ka hoʻokele ʻana o bes Funkenerosion. ʻOiaʻiʻo, he mea pōmaikaʻi kēia, no ka mea, ʻaʻole hiki ke loaʻa i kahi pani kūpono no kahi ʻoihana hana. ʻAʻole ia he mea maʻamau no nā mea hoʻopukapuka kālā haole i hoʻomaopopo ʻole i ka erosion a i ʻole ke kaiapuni o ka mea kūʻai aku e lawe. Ma hope o kekahi mau makahiki, kūʻai hou ʻia kēia mau ʻoihana ma ke ʻano he "ʻāpana pākahi" a laila panakalupa. Eia naʻe, ma lalo o ke alakaʻi ʻana a Markus Langenbacher, ua lawe kahi limahana akamai loa i ke poʻo. Ma hope o 21 mau makahiki me ka ʻoihana, ʻaʻole ʻo ia i ʻike wale i ka ʻoihana a me nā kaʻina hana i loko a i waho, akā ʻo nā mea kūʻai aku hoʻi.
Ua ʻike maikaʻi ʻo Markus Langenbacher i nā hopohopo o kāna mau mea kūʻai aku: "ʻO ka pane a ka mea kūʻai aku, ʻo ia ke kali i nā makahiki ʻelua a ʻekolu paha ma mua o ke kau ʻana i kahi kauoha.

He mea hoihoi kēia hui hōkū no ka mea ua ʻike ka limahana kekahi i kekahi no 20 mau makahiki, a i kēia manawa ua lilo koke ka hoa hana mua i luna. ʻO Jörg Roming, ka mea i noho me ka hui no 18 mau makahiki, ʻike ʻo ia i kēia he mea maikaʻi loa: "Ke kamaʻilio ākea nei mākou kekahi i kekahi no ka mea ua ʻike mākou kekahi i kekahi no ka manawa lōʻihi.

I ka hopena, loaʻa pū nā mea hoʻolako e like me Sodick i ka pōmaikaʻi mai ka hoʻomohala maikaʻi holoʻokoʻa o EDM. Ma hope o ka hāʻawi ʻia ʻana o ka ALC400G liʻiliʻi i ka hui ʻo Fluorn-Winzeln ma ke ʻano he mīkini pani i ka hoʻomaka ʻana o 2021, ua ukali ʻia kona hoa nui, ʻo ALC800GH, i ka hopena o ke kauwela. "Ua lawe mākou i nā hana mua e hoʻonui hou aku i kā mākou ʻoihana ʻaelike WEDM i nā ʻāpana XXL me kahi mīkini WEDM nui aʻe. ʻAe kēia iā mākou e lawelawe wale i kēia mākeke a ʻaʻole pono hou mākou e hōʻole i nā kauoha," wahi a ka luna hoʻokele ʻo Markus Langenbacher. E hoʻopuka ʻia nā kauoha hou ma ka hāʻawi ʻana i ka ʻike i kahi waihona mea kūʻai aku ākea. "Ma o kā mākou paka mīkini, ke hoʻāʻo nei mākou e kuhikuhi pono i kekahi o nā mea kūʻai aku i loaʻa iā mākou ma ka ʻeli ʻana o EDM.

I nā makahiki i hala iho nei, ua loaʻa iā bes Funkenerosion kahi wahi kūʻai kūikawā ma ke kahua o ka uea EDM: me kahi ala ʻaoʻao o 1460 x 600 x 1,020 mm, hiki ke wili i nā ʻāpana a hiki i 6 tons.

I ka wā mua, ua kūʻai ʻia ka Sodick VL600QH ma ke ʻano he mīkini pani. Akā, no ka mea, ua kūʻai ʻia ka ALC800GH no kekahi manawa pōkole, ua nānā ʻo Markus Langenbacher lāua ʻo Jörg Roming a ua hoʻoholo hope e kākoʻo iā ia. "Eia kekahi, me ka mīkini wili EDM a mākou e hoʻohana ai, loaʻa iā mākou kahi ala ʻaoʻao, a kūpono ka ALC800GH no ka pani ʻana i ka pōʻai ma waena o ka hoʻomaka ʻana o ka wili ʻana o 800 mm (hiki a hiki i ka 1,000 mm) a me ka uea 800 mm EDM EDM", wahi a Jörg Roming. Ua māʻona pū nā mīkini EDM hou i kēia ʻano.
He hoʻololi maʻalahi ia: ua wehe ʻia ka mīkini kahiko, ua hōʻea mai kahi trailer flatbed me ka mīkini XXL, a ua hoʻololi ʻia ka mīkini kahiko no ka mīkini hou, me nā mālama kālā like ʻana i nā kumukūʻai hoʻouna. "Hana pū mākou ʻelua ma ke ala maikaʻi loa," hōʻoia ʻo Jörg Roming. ʻOiai ka mīkini ma ka hale, ua hoʻāʻo ʻo ia me kahi kihi granite i hoʻoponopono ʻia i 2 mika a me ka lōʻihi o 800 mm.

Ma ke ala, ke hoʻomau nei ka hana i hoʻomaka ma ka mīkini kahiko i kēia manawa ma ka mīkini hou: ʻoki ʻana i ke kiʻekiʻe 358 mm. "Ua ʻike koke mākou i ka ʻokoʻa o ka maikaʻi. ʻO kekahi pōmaikaʻi nui no mākou, ʻo ia ka aneane like o ka ʻōnaehana hoʻomalu, koe wale nō kekahi mau hoʻomaikaʻi.

No nā kaula, hōʻike ka EDM hou i kahi lele nui i mua, a ʻo ka ʻoiaʻiʻo ua hoʻohui ʻia nā ʻōkuhi hana ma ka ʻōnaehana kaohi he pōmaikaʻi nui ia, wahi āna. ʻAʻohe huli hou a me ka ʻimi ʻana i nā manual mea hoʻohana a me nā manual papahana.

Hiki i kā mākou ʻano o nā mīkini EDM uea ke hana a hiki i 500 mau ʻāpana. "No mākou ma ke ʻano he poʻe loea EDM, he nui loa kēia," wahi a Jörg Romen. ʻO ka awelika o ka nui no ka hana nui ʻana ma waena o 2 a me 20 mau ʻāpana, akā ua hana ʻia kahi hapa nui o nā ʻāpana pākahi. ʻAʻole kēia ka hihia me ka wili ʻana, kahi i ʻike ʻole ʻia ai ka moʻo hebedoma 1,000-ʻāpana.
