Indlela yokukhetha i-drill drill bit ye-speed high-speed: izinto eziqinisekileyo zezinto kunye nomgangatho

Njengesixhobo esiyimfuneko kwimveliso yemizi-mveliso kunye nokuchaneka komatshini, umgangatho we-high-speed steel drill bits (i-HSS Drill Bits) ichaphazela ngokuthe ngqo ukusebenza kakuhle, ukuchaneka komatshini kunye nobomi besixhobo. Nangona kunjalo, phakathi kweemveliso ezininzi zentsimbi zesantya esiphezulu kwimarike, indlela yokukhetha imathiriyeli efanelekileyo kunye nemigangatho yomgangatho ngumceli mngeni ekufuneka ajongane nawo wonke umthengi kunye nomenzi. Eli nqaku liza kubonisa iimpawu eziphathekayo ze-speed-speed drill bits, izinto ezichaphazela umgangatho, kunye nendlela yokwenza ukhetho olufanelekileyo ngokweemfuno zakho.

Ukubunjwa kwezinto eziphathekayo kwi-high-speed steel drill bits
Iintsimbi ezikhawulezayo zokuqhuba intsimbi zidla ngokwenziwa ngentsimbi yesantya esiphezulu (HSS). Le alloy yensimbi inobunzima obuphezulu, ukumelana nokunxiba okuphezulu kunye nokuzinza okuphezulu kwe-thermal, ngoko inokugcina ukusebenza ngokufanelekileyo kokusika ngexesha lokusebenza ngesantya esiphezulu. Ukubunjwa kwe-alloy ye-speed-speed drill bits yinto ephambili yokumisela umgangatho kunye nokusebenza kwayo.

Izinto eziqhelekileyo zentsimbi enesantya esiphezulu ziquka:

Intsimbi ye-M2 ephezulu
I-M2 iyona nto ixhaphakileyo yensimbi ephezulu, ifanelekile kwiinkqubo ezahlukeneyo zokugaya. Ngokuqhelekileyo iqulethe i-molybdenum, i-tungsten kunye nenani elincinci le-cobalt, inokumelana nokunxiba kakuhle kunye nokuqina, kwaye ifanelekile ukugrumba iintsimbi eziqhelekileyo ezifana ne-aluminium, ubhedu kunye nentsimbi.

Intsimbi ye-M35 yesantya esiphezulu
I-M35 inobunzima obuphezulu kunye nokumelana nokushisa okuphezulu kune-M2, kwaye ifanelekile ngokukodwa kwizicelo ezifuna ukucutshungulwa kwesinyithi esinzima (njengensimbi engenasici kunye ne-alloy steel). Umxholo ophezulu we-cobalt we-M35 (malunga ne-5%) uphucula kakhulu ukumelana nokushisa kunye nokwandisa ubomi benkonzo.

M42 High Speed Steel
I-M42 igxininisa ukuxhathisa okuphezulu kakhulu kunye nokumelana nokushisa okuphezulu, kwaye isetyenziswa ngokubanzi ekwembeni isinyithi esiqinileyo kunye ne-alloys. Umxholo wayo we-cobalt uphezulu njenge-8%, enokumelana namaqondo okushisa aphezulu kunye noxinzelelo.

Izinto ezichaphazela umgangatho we-high-speed steel drills
Xa ukhetha i-speed-speed drills, kubalulekile ukuqonda izinto ezichaphazela umgangatho. Nantsi imigangatho embalwa yobulunga engundoqo:

Ukuqulunqwa kwe-alloy kunye nenkqubo
Ukubunjwa kwe-alloy kunye nenkqubo yokunyanga ukushisa kwe-high-speed steel drills sisiseko sokumisela ukusebenza kwabo. Ngokomzekelo, imixholo eyahlukeneyo kunye neenkqubo zonyango ze-M2, i-M35 kunye ne-M42 izinto ziya kuchaphazela ngokuthe ngqo ubunzima, ukuqina kunye nokuxhatshazwa kokugqoka kwe-drill. Iidrill ezikumgangatho ophezulu zihlala ziphathwa ngokungqongqo ubushushu ukuqinisekisa ukuzinza kwazo kumaqondo obushushu aphezulu kunye nokujikeleza ngesantya esiphezulu.

Ukuchaneka kunye nenkqubo yokuvelisa
Iibhithi zokugrumba ezichanekileyo zinokuqinisekisa ukuchaneka kunye nokugqitywa komphezulu wokomba. Xa ukhetha, ingqalelo ekhethekileyo kufuneka ihlawulwe kunyango lomphezulu we-drill bit, njengokuchaneka kokugaya, i-helix angle design, i-center point shape, njl., Emisela ukuzinza kunye nomgangatho wokugaya ngexesha lokusika.

Itekhnoloji yokwambathisa
Kwiminyaka yakutshanje, ukusetyenziswa kwetekhnoloji yokwambathisa kubonelele ngamathuba angakumbi okuphucula ukusebenza kweentsimbi zokubhola ngesantya esiphezulu. Iingubo eziqhelekileyo ziquka i-titanium coating (TiN), i-titanium nitride coating (TiAlN), njl. Ezi ngqungquthela zinokuphucula ngokufanelekileyo ubunzima, ukuxhathisa ukugqoka kunye nokuxhatshazwa kwe-corrosion ye-drill bit, ukwandisa ubomi benkonzo ye-drill bit, kwaye inokusebenza kumaqondo okushisa aphezulu.

Uyilo lwesuntswana lokubhola
Umgangatho ophezulu we-speed-speed drill bits uhlala unoyilo oluchanekileyo, ngakumbi kwi-angle ye-helix, i-angle yesikhokelo kunye ne-cut cut edge shape. Uyilo olunengqiqo lunokuqinisekisa ukuzinza, ukusika ukusebenza kakuhle kunye nomgangatho wokugaya xa ubhobhoza kwizinto ezahlukeneyo.

Indlela yokukhetha i-speed high-speed drill bit
Ukukhetha i-speed high-speed drill bits ayisekelwe kuphela kwixabiso, kodwa iqwalasela iimfuno zangempela zomsebenzi. Oku kulandelayo zizinto ezininzi eziphambili xa ukhetha:

Uhlobo lwezinto zokusebenza
Izixhobo ezahlukeneyo zineemfuno ezahlukeneyo ze-drill bits. Kwiintsimbi ezithambileyo (ezifana ne-aluminium kunye nobhedu), i-M2 ye-speed drill ye-speed drills inokuhlangabezana neemfuno. Kwizinto ezilukhuni zetsimbi (ezifana nensimbi engenasici kunye ne-alloy steel), kucetyiswa ukuba ukhethe i-M35 okanye i-M42 i-drill ye-speed-speed drills, enokubonelela ngokuxhathisa ukushisa okuphezulu kunye nokuxhatshazwa kokugqoka.

Idayimitha yokomba kunye nobunzulu
Ubungakanani kunye nobunzulu be-drill buya kuchaphazela ukucaciswa kwe-drill. Ngokubanzi, imingxunya emikhulu yedayamitha ifuna ukugrunjwa komgangatho ophezulu ukugcina ukuchaneka kokusika. Ukongeza, ubunzulu bokugaya buya kuchaphazela uyilo lwesakhiwo se-drill, njenge-drill drill, i-slender drills, njl.

Indawo yokusebenza kunye neemeko zokusika
Ngesantya esiphezulu, umthwalo ophezulu okanye indawo yokushisa ephezulu, kubaluleke kakhulu ukukhetha ii-drills ze-HSS ezinokumelana nokushisa okuphezulu kunye nokumelana nokugqoka okuphezulu. I-coated drills ifaneleke ngokukodwa ukusika isantya esiphezulu kunye neemeko zokushisa eziphezulu, ezinokwandisa ngokufanelekileyo ubomi benkonzo.

Uhlahlo lwabiwo-mali kunye nokukhetha uphawu
Umahluko wexabiso le-high-speed steel drills kwimarike inkulu. Indlela yokufumana ibhalansi phakathi kokusebenza kunye neendleko kukuqwalaselwa okubalulekileyo xa ukhetha. Ukukhetha uphawu olunegama elihle kunokuqinisekisa umgangatho kunye nenkonzo emva kokuthengiswa kwemveliso. Iimpawu ezaziwayo zihlala zibonelela ngengqinisekiso yomgangatho ongcono kunye nenkxaso yobugcisa ebanzi.

Ukugcinwa kunye nokugcinwa kweentsimbi ze-speed-speed drill bits
Umgangatho ophezulu we-speed drill bits uhlala unobomi obude benkonzo, kodwa ngexesha lokusetyenziswa, ukulungiswa okufanelekileyo kunye nokugcinwa kunokwandisa ubomi babo benkonzo:

Ukucoca rhoqo: Gcina i-drill bit icocekile kwaye ususe iitshiphu zetsimbi ezenziwe ngexesha lokugaya ukuphepha ukuchaphazela ukusika ukusebenza kakuhle.

Ukupholisa okunengqiqo: Ukusebenzisa ulwelo lokusika okanye ukupholisa, ngakumbi xa kusetyenzwa izinto ezinamandla kakhulu, kunokuthintela ngokufanelekileyo ubushushu obugqithisileyo kunye nokwandisa ubomi bento yokubhola.

Qwalasela ukunxiba: Qwalasela umphetho kunye nokuguga komphezulu we-drill bit, kwaye ulole okanye utshintshe amasuntswana e-drill eyonakeleyo ngexesha.

Isishwankathelo
Amasuntswana okomba esinyithi anesantya esiphezulu abe sisixhobo esiyimfuneko kwimveliso yemizi-mveliso ngenxa yokusebenza kwawo okugqwesileyo kunye nokusebenza okubanzi. Ngokuqonda iipropati zabo eziphathekayo, imigangatho yomgangatho, kunye nendlela yokwenza ukhetho olufanelekileyo olusekelwe kwiimfuno zomsebenzi, abasebenzisi banokuphucula ngokufanelekileyo ukusebenza kakuhle kokomba kunye nokuchaneka kokucubungula. Ingaba kwiprosesa yesinyithi, ukwakhiwa okanye ukuveliswa ngokuchanekileyo, ukukhetha i-drill drill bit ye-speed drill yeyona nto ibalulekileyo ekuphuculeni umgangatho womsebenzi kunye nokunciphisa iindleko.
