Embonini yamathuluzi,Izingxenye ze-DIN338zivame ukudunyiswa “njengebenchmark enembile”, ikakhulukaziIzingxenye zokubhoboza ze-DIN338 HSSCO, okuthiwa zenziwe nge-cobalt-containing high-speed steel, zize zikhuthazwe ngokuthi "isixazululo esiphezulu sokumba izinto eziqinile". Kodwa-ke, ezinhlelweni zokusebenza zezimboni zangempela kanye nempendulo yomsebenzisi, ingabe lawa mathuluzi enziwe nguNkulunkulu angaphila ngokwezithembiso zawo? Ake singene eqinisweni ngemuva kwemakethe.
I. DIN338 Izinga: Imikhawulo Ngaphansi Kokugqama
I-DIN338, njengendinganiso yezimboni yaseJalimane yokuprakthiza i-straight shank twist, ngempela ibeka izidingo eziyisisekelo zejometri, ukubekezelela kanye nempahla yezinsimbi zokubhola. Kodwa-ke, “ukuvumelana ne-DIN338″ akulingani “nekhwalithi ephezulu”. Inani elikhulu lama-drill bits ashibhile emakethe alingisa nje ukubonakala kodwa akude nokuhlangabezana nemingcele eyinhloko:
- Ukulebula kwezinto ezingamanga kudlangile: Abanye abakhiqizi balebula izingcezu zokubhoboza zensimbi enesivinini esiphezulu (HSS) njengokuthi “HSSCO”, kodwa okuqukethwe kwe-cobalt kwangempela kungaphansi kuka-5%, kude nokuhlangabezana nezindinganiso ezidingekayo zokucubungula izinto eziqinile.
- Amaphutha enqubo yokwelapha ukushisa: Impendulo yomsebenzisi ikhombisa ukuthi ezinye izinsimbi zokubhoboza ze-DIN338 zicwiliswa ngaphambi kwesikhathi phakathi nenqubo yokumba, futhi nokuchopha kwenzeka lapho kucutshungulwa insimbi engagqwali.
- Ukungaguquguquki okungalungile ekunembeni: Ukubekezelela ububanzi bezinsimbi zokubhola eqoqweni elifanayo kushintshashintsha kakhulu, kuthinte kabi ukunemba kokuhlanganiswa.
2. I-DIN338 HSSCO Drill Bit: “Inganekwane Yokumelana Nokushisa” Eyedlulele
Insimbi enesivinini esikhulu equkethe i-cobalt ingathuthukisa ukuqina okubomvu nokumelana nokugqokwa kwezingcezu zokubhoboza, kodwa ukusebenza kwayo kwangempela kuncike kakhulu ekuhlanzekeni kwezinto ezingavuthiwe nezinqubo zokwelashwa kokushisa. Uphenyo luthole:
- Iphromoshini yesikhathi sokuphila esiphansi: Isikhungo sokuhlola senkampani yangaphandle siqhathanise amabhrendi amahlanu e-DIN338 HSSCO drill bits. Lapho kubholwa insimbi engagqwali engu-304 ngokuqhubekayo, yizinhlobo ezimbili kuphela eziphile isikhathi esingaphezu kwezimbobo ezingama-50, kuyilapho zonke ezinye zaguga ngokushesha.
- Ukukhishwa kwe-chip: Eminye imikhiqizo, ukuze yehlise izindleko, inciphisa inqubo yokupholisha i-spiral groove, okuholela ekunamatheleni kwe-chip, okwenza kube nzima ukushisisa kwe-drill bit kanye nemihuzuko endaweni yokusebenza.
- Imikhawulo yezinto ezisebenzayo: Isimangalo kuphromoshini sokuthi "isebenza kuwo wonke ama-alloys" siyadukisa kakhulu. Okwezinto eziqinile (ezifana nama-titanium alloys nama-superalloy), izingcezu zokubhoboza zekhwalithi ephansi ze-DIN338 HSSCO azikwazi ukususa ama-chips futhi esikhundleni salokho zisheshise ukwehluleka.
3. Igebe langempela phakathi kokulawulwa kwekhwalithi kanye Nesevisi yangemuva kokuthengisa
Nakuba abanye abakhiqizi bethi "banamaqembu ezobuchwepheshe athuthukile" kanye "nesevisi yamazwe ngamazwe ngemva kokuthengisa", izikhalazo zabasebenzisi zigxile kakhulu kulokhu:
- Imibiko yokuhlola engekho: Abahlinzeki abaningi abakwazi ukunikeza ukuhlolwa kokuqina kanye nemibiko yokuhlaziya i-metallographic kuqoqo ngalinye lamabhithi okubhola.
- Ukusabela okunensayo kosekelo lobuchwepheshe: Abasebenzisi baphesheya kwezilwandle babike ukuthi imibuzo emayelana nokukhetha ibhithi yokubhoboza nokusetshenziswa ngokuvamile ayiphendulwa.
- Ukweqa isibopho sangemva kokuthengisa: Uma kunezinkinga ngokunemba kokumba, abakhiqizi bavame ukukuhlobanisa "nokusebenza okungafanele" kwabasebenzisi noma "ukupholisa okunganele".
4. I-Industry Reflection: Ungawadedela Kanjani Amathuba Okunemba?
Isitifiketi esijwayelekile sokucaciswa
Izinga le-DIN338 kufanele liqhubeke lihlukanise amamaki okusebenza (njengokuthi “ibanga lemboni” kanye “nebanga lochwepheshe”), futhi lidinga ngokuphoqelekile ukumakwa kwamapharamitha abalulekile njengokuqukethwe kwe-cobalt nenqubo yokwelapha ukushisa.
Abasebenzisi kumele baqaphe ngezinkulumo zokumaketha
Lapho uthenga, izinqumo akufanele zenziwe ngokusekelwe egameni elithi “DIN338 HSSCO”. Kunalokho, izitifiketi zezinto ezibonakalayo nedatha yokulinganisa yangempela kufanele icelwe, futhi abahlinzeki abahlinzeka ngamaphakheji esilingo kufanele banikezwe kuqala.
Isiqondiso sokuthuthukiswa kobuchwepheshe
Imboni kufanele ishintshele kubuchwepheshe bokumboza (okufana nokuhlanganisa i-TiAlN) kanye nezinto ezintsha zesakhiwo (ezifana nedizayini yembobo yokupholisa yangaphakathi), kunokuthembela kuphela ekulungiseni kahle izinto zokwakha.
Isiphetho
Njengemikhiqizo yakudala emkhakheni wamathuluzi, amandla weIzingxenye ze-DIN338futhiIzingxenye zokubhoboza ze-DIN338 HSSCOakungabazeki. Kodwa-ke, imakethe yamanje igcwele imikhiqizo yekhwalithi ehlukahlukene kanye namaphromoshini apakishwe ngokweqile, aqeda ukwethembeka kwaleli zinga. Kubasebenzi, kuphela ngokungena enkunguni yokumaketha nokusebenzisa idatha yokulinganisa yangempela njengendawo yokulinganisa bangathola izixazululo ezithembeke ngempela zokumba - phela, ukunemba akufinyelelwa ngelebula eyodwa.
