Embonini yamathuluzi,Izingcezu zokubhoboza ze-DIN338zivame ukubizwa ngokuthi “isilinganiso sokunemba”, ikakhulukaziIzingcezu zokubhoboza ze-DIN338 HSSCO, okuthiwa zenziwe ngensimbi yesivinini esiphezulu equkethe i-cobalt, zize ziphakanyiswe njenge "isixazululo esiphezulu sokubhoboza izinto eziqinile". Kodwa-ke, ezisetshenzisweni zangempela zezimboni kanye nempendulo yabasebenzisi, ingabe la mathuluzi aqanjwe njengonkulunkulu angafeza izithembiso zawo ngempela? Ake sihlole iqiniso elingemuva kwemakethe.
I. Izinga le-DIN338: Imikhawulo Ngaphansi Kokugqanyiswa
I-DIN338, njengendinganiso yezimboni yaseJalimane yama-drill aqondile, empeleni ibeka izidingo eziyisisekelo ze-geometry, ukubekezelelana kanye nezinto zokwakha ama-drill bits. Kodwa-ke, "ukuhambisana ne-DIN338″ akusho ukuthi "ikhwalithi ephezulu". Inani elikhulu lama-drill bits ashibhile emakethe alingisa ukubukeka kodwa awahlangabezani nemingcele eyinhloko:
- Ukulebula izinto ezingamanga kudlangile: Abanye abakhiqizi babiza ama-drill bits ajwayelekile ensimbi enesivinini esikhulu (i-HSS) ngokuthi “i-HSSCO”, kodwa okuqukethwe kwe-cobalt kwangempela kungaphansi kuka-5%, kude kakhulu nokuhlangabezana nezindinganiso ezidingekayo zokucubungula izinto eziqinile.
- Amaphutha enkambisweni yokwelashwa kokushisa: Impendulo yomsebenzisi ikhombisa ukuthi ezinye izingcezu zokubhoboza ze-DIN338 zifakwa ekufakweni kwensimbi engagqwali ngaphambi kwesikhathi ngesikhathi senqubo yokubhoboza, futhi ngisho nokuqhekeka kwenzeka lapho kucutshungulwa insimbi engagqwali.
- Ukungaguquguquki kahle kokunemba: Ukubekezelela ububanzi bezingcezu zokubhoboza kuqoqo elifanayo kuyashintshashintsha kakhulu, okuthinta kakhulu ukunemba kokuhlanganiswa.
2. I-DIN338 HSSCO Drill Bit: “Inganekwane Yokumelana Nokushisa” Eyeqile
Insimbi yesivinini esiphezulu equkethe i-cobalt ingathuthukisa ubulukhuni obomvu kanye nokumelana nokuguguleka kwama-drill bits, kodwa ukusebenza kwayo kwangempela kuncike kakhulu ekuhlanzekeni kwezinto zokusetshenziswa kanye nezinqubo zokwelapha ukushisa. Uphenyo luthole:
- Ukukhuthazwa kokuphila okuphansi: Isikhungo sokuhlola seqembu lesithathu siqhathanise izinhlobo ezinhlanu zezingcezu zokubhola ze-DIN338 HSSCO. Lapho kuqhubeka kubholwa insimbi engagqwali engu-304, izinhlobo ezimbili kuphela ezazinokuphila okungaphezu kwezimbobo ezingu-50, kanti ezinye zonke zaziguga ngokushesha.
- Inkinga yokususwa kwe-chip: Eminye imikhiqizo, ukuze kuncishiswe izindleko, inciphisa inqubo yokupholisha ye-spiral groove, okuholela ekunamatheleni kwe-chip, okwenza kube nzima kakhulu ukushisa kwe-drill bit kanye nokuklwebheka endaweni yokusebenza.
- Imikhawulo yezinto ezisebenzayo: Isimangalo esikuphromoshini sokuthi "sisebenza kuzo zonke izinhlobo ze-alloy" siyadukisa kakhulu. Ngezinto zokuqina okuphezulu (njengezinhlobo ze-titanium alloys nama-superalloy), ama-drill bits e-DIN338 HSSCO asezingeni eliphansi awakwazi ukususa ama-chips ngempumelelo futhi asheshise ukwehluleka.
3. Igebe langempela phakathi kokulawulwa kwekhwalithi kanye nensizakalo yangemva kokuthengisa
Nakuba abanye abakhiqizi bethi “banamaqembu obuchwepheshe athuthukile” kanye “nensizakalo yamazwe ngamazwe ngemuva kokuthengisa”, izikhalazo zabasebenzisi zigxile kakhulu ku:
- Imibiko yokuhlola engekho: Iningi labaphakeli alikwazi ukunikeza imibiko yokuhlolwa kobulukhuni kanye nokuhlaziywa kwe-metallographic yeqoqo ngalinye lama-drill bits.
- Impendulo ehamba kancane yokusekelwa kobuchwepheshe: Abasebenzisi baphesheya kwezilwandle babike ukuthi imibuzo ephathelene nokukhethwa kwama-drill bit kanye nokusetshenziswa kwawo ivame ukungaphendulwa.
- Ukugwema umthwalo wemfanelo ngemva kokuthengisa: Uma kunezinkinga ngokunemba kokubhoboza, abakhiqizi bavame ukuzibiza ngokuthi “ukusebenza okungafanele” kwabasebenzisi noma “ukupholisa okunganele”.
4. Ukuzindla Ngemboni: Ungawakhipha Kanjani Ngempela Amandla Okunemba?
Isitifiketi esijwayelekile sencazelo
Izinga le-DIN338 kufanele lihlukanise amazinga okusebenza (njenge-"ibanga lezimboni" kanye ne-"ibanga lochwepheshe"), futhi lidinga ngokuphoqelekile ukumaka amapharamitha abalulekile njengokuqukethwe kwe-cobalt kanye nenqubo yokwelapha ukushisa.
Abasebenzisi kudingeka baqaphele ngenkulumo yokumaketha
Lapho uthenga, izinqumo akufanele zenziwe ngokusekelwe egameni elithi “DIN338 HSSCO” kuphela. Kunalokho, kufanele kucelwe izitifiketi zezinto ezibonakalayo kanye nedatha yokulinganisa yangempela, futhi abahlinzeki abahlinzeka ngamaphakheji okuhlola kufanele banikezwe kuqala.
Isiqondiso sokuthuthukiswa kobuchwepheshe
Imboni kufanele ishintshele kubuchwepheshe bokumboza (njengokumboza kwe-TiAlN) kanye nokusungula izinto ezintsha (njengokuklanywa kwemigodi yokupholisa yangaphakathi), kunokuthembela kuphela ekulungisweni kahle kwezinto zokwakha.
Isiphetho
Njengemikhiqizo yakudala emkhakheni wamathuluzi, amandlaIzingcezu zokubhoboza ze-DIN338futhiIzingcezu zokubhoboza ze-DIN338 HSSCOakungabazeki. Kodwa-ke, imakethe yamanje igcwele imikhiqizo yekhwalithi ehlukahlukene kanye nokukhushulwa okupakishwe ngokweqile, okunciphisa ukwethembeka kwaleli zinga. Kwabasebenza, kuphela ngokungena enkungwini yokumaketha nokusebenzisa idatha yokulinganisa yangempela njengesilinganiso lapho bengathola khona izixazululo zokubhoboza ezithembekile ngempela - phela, ukunemba akukaze kufezwe ilebula elilodwa.
