Ma ka ʻōlelo maʻamau, hiki ke hoʻokaʻawale ʻia nā ʻano hana wehe burr i ʻehā mau ʻāpana:
1. Ka pae koʻikoʻi (pili paʻakikī)
Aia i loko o kēia ʻāpana ʻo ka ʻokiʻoki, ka wili ʻana, ka waiho ʻana a me ka hana scraper.
2. Ka pae maʻamau (pā palupalu)
Aia i loko o kēia māhele ka wili kāʻei, wili, wili huila elastic a me ka polishing.
3. Ka pae pololei (pili maʻalahi)
Aia i loko o kēia ʻāpana ʻo ka flushing processing, electrochemical processing, electrolytic grinding and rolling processing.
4. Ka pae kiʻekiʻe loa (pili pololei)
No kēia māhele, he abrasive flow deburring, magnetic grinding deburring, electrolytic deburring, thermal deburring a me radium dense ultrasonic deburring ikaika, etc. Hiki i kēia ʻano o ka deburring ke loaʻa i ka pololei o ka hoʻoili ʻana.
Ke koho mākou i kahi ala deburring, pono mākou e noʻonoʻo i nā kumu he nui, e like me ke ʻano o ka ʻāpana, ke ʻano o ke ʻano, ka nui a me ka pololei. ʻO ka mea kūikawā, pono mākou e hoʻolohe i nā loli i ka ʻili o ka ʻili, ka ʻae ʻana o ka dimensional, deformation, a me ke koʻikoʻi koena.
ʻO ka mea i kapa ʻia ʻo electrolytic deburring he ʻano hana deburring kemika. Hiki iā ia ke wehe i nā burrs ma hope o ka mīkini ʻana, ka wili ʻana a me ke kuʻi ʻana, a puni a i ʻole chamfer i nā kihi ʻoi o nā ʻāpana metala.
He ʻano hana hana electrolytic e hoʻohana ana i ka electrolysis e wehe i nā burrs mai nā ʻāpana metala, i kapa ʻia ʻo ECD ma ka ʻōlelo Pelekania. E hoʻopaʻa i ka cathode mea hana (i hana mau ʻia me ke keleawe) kokoke i ka ʻāpana burr o ka mea hana, me kahi āpau (maʻamau 0.3 a 1 mm) ma waena o lākou. Hoʻopili ʻia ka ʻāpana conductive o ka cathode hāmeʻa me ka ʻaoʻao burr, a ua uhi ʻia nā ʻaoʻao ʻē aʻe me kahi papa insulating e hoʻokau i ka electrolysis ma ka ʻaoʻao burr.
I ka wā o ka hana ʻana, pili ka cathode o ka mea hana i ka pole maikaʻi ʻole o ka mana DC, a pili ka mea hana i ka pou kūpono o ka mana DC. ʻO kahi electrolyte haʻahaʻa haʻahaʻa (ʻo ka sodium nitrate a i ʻole ka sodium chlorate aqueous solution) me ke kaomi o 0.1 a 0.3 MPa e kahe ana ma waena o ka mea hana a me ka cathode. Ke hoʻohuli ʻia ka mana DC, e hoʻoheheʻe nā burrs i ka anode a wehe ʻia, a e lawe ʻia e ka electrolyte.
He mea ʻino ka electrolyte i kekahi ʻano, a pono e hoʻomaʻemaʻe ʻia ka mea hana a hoʻopaʻa ʻia ma hope o ka deburring. He kūpono ka deburring electrolytic no ka wehe ʻana i nā burrs mai nā lua keʻa i nā ʻāpana huna a i ʻole nā ʻāpana me nā ʻano paʻakikī. Loaʻa iā ia ka maikaʻi hana kiʻekiʻe a ʻo ka manawa deburring maʻamau he mau kekona wale nō a i ʻumi kekona.
