Ukuqina kwe-Vickers HV (ikakhulukazi ukukala ubulukhuni bobuso)
Sebenzisa i-indenter yekhoni yesikwele yedayimane enomthwalo omkhulu ongu-120 kg kanye ne-engeli ephezulu engu-136° ukuze ucindezele endaweni ebonakalayo futhi ulinganise ubude be-diagonal bokuhlehlisa. Le ndlela ifaneleka ekuhloleni ubulukhuni bezingcezu zokusebenza ezinkulu nezingqimba ezijulile zangaphezulu.
I-Leeb hardness HL (umhloli wokuqina ophathwayo)
Indlela ye-Leeb yobulukhuni isetshenziselwa ukuhlola ubulukhuni bezinto. Ivelu yobulukhuni be-Leeb inqunywa ngokulinganisa isivinini sokubuyela emuva somzimba onomthelela wenzwa yokuqina ngokuhlobene nesivinini somthelela ebangeni elingu-1mm ukusuka phezulu kwendawo yokusebenza phakathi nenqubo yomthelela, bese siphindaphinda lesi silinganiso ngo-1000.
Izinzuzo:Umhloli wokuqina ka-Leeb, osuselwe kuthiyori yobulukhuni be-Leeb, uguqule izindlela zokuhlola ubulukhuni ezivamile. Usayizi omncane wenzwa yokuqina, efana neyepeni, uvumela ukuhlolwa kokuqina okubanjwa ngesandla kuzingcezu zokusebenza ngezindlela ezahlukahlukene endaweni yokukhiqiza. Leli khono linzima kwabanye abahloli bokuqina bedeskithophu ukufanisa.
Kunamathuluzi ahlukahlukene okwenza imishini, kuye ngohlobo lwento esetshenzwa ngayo. Amathuluzi asetshenziswa kakhulu okuncike kwesokunxele, ukuncika kwesokudla, nokuncika phakathi, njengoba kuboniswe esithombeni esingezansi, ngokusekelwe ohlotsheni lomphathi owenziwa ngomshini. Ukwengeza, amathuluzi we-tungsten carbide anezingubo zokushisa eziphezulu angasetshenziswa ukusika insimbi noma izinto ezingagugi.
2. Ukuhlolwa kwethuluzi
Hlola ngokucophelela ummese osikiwe ngaphambi kokuwusebenzisa. Uma usebenzisa izinsimbi zokusika ze-high-speed steel (HSS), lola ummese ukuze uqinisekise ukuthi ubukhali. Uma usebenzisa ummese wokuhlukanisa i-carbide, hlola ukuthi i-blade isesimweni esihle yini.
3. Khulisa ukuqina kokufakwa kommese wokusika
Ukuqina kwethuluzi kukhuliswa ngokunciphisa ubude bethuluzi eliphumela ngaphandle kwe-turret. Amadayamitha amakhudlwana noma ama-workpiece aqinile adinga ukulungiswa izikhathi ezimbalwa lapho ithuluzi lisika phakathi kokuhlukana.
Ngesizathu esifanayo, ukuhlukaniswa kuhlale kwenziwa eduze ne-chuck ngangokunokwenzeka (ngokuvamile cishe ku-3mm) ukuze kwandiswe ukuqina kwengxenye ngesikhathi sokuhlukaniswa, njengoba kuboniswe esithombeni.
4. Qondanisa ithuluzi
Ithuluzi kufanele liqondaniswe kahle ne-x-eksisi ku-lathe. Izindlela ezimbili ezijwayelekile zokufeza lokhu ukusebenzisa ibhulokhi yokumisa ithuluzi noma igeji yokudayela, njengoba kuboniswe esithombeni.
Ukuqinisekisa ukuthi ummese wokusika u-perpendicular phambi kwe-chuck, ungasebenzisa i-gauge block ene-parallel surface. Okokuqala, khulula i-turret, bese uqondanisa unqenqema lwe-turret ne-gauge block, futhi ekugcineni, qinisa kabusha izikulufu. Qaphela ukuthi ingawi igeji.
Ukuqinisekisa ukuthi ithuluzi li-perpendicular ku-chuck, ungasebenzisa futhi igeji yokudayela. Namathisela igeji yokudayela endongeni yokuxhuma bese uyibeka kumzila wesitimela (ungasheleli eduze nomzila wesitimela; yilungise endaweni). Khomba othintana naye ethuluzini bese ulihambisa eduze kwe-x-eksisi ngenkathi ubheka izinguquko kugeji yokudayela. Iphutha elingu-+/-0.02mm liyamukeleka.
5. Hlola ukuphakama kwethuluzi
Uma usebenzisa amathuluzi kuma-lathes, kubalulekile ukuhlola futhi ulungise ubude bommese ohlukanisayo ukuze usondele eduze komugqa omaphakathi we-spindle ngangokunokwenzeka. Uma ithuluzi lokuhlukanisa lingekho kumugqa omaphakathi oqondile, ngeke lisike kahle futhi lingase lonakale ngesikhathi somshini.
Njengeminye imimese, imimese ehlukanisayo kufanele isebenzise ileveli ye-lathe noma irula ukuze ithiphu ibe kumugqa omaphakathi oqondile.
6. Faka amafutha okusika
Uma usebenzisa imoto evamile, ungasebenzisi ukudla okuzenzakalelayo, futhi qiniseka ukuthi usebenzisa amafutha amaningi okusika, ngoba inqubo yokusika ikhiqiza ukushisa okukhulu. Ngakho, kushisa kakhulu ngemva kokusika. Faka amafutha amaningi okusika esihlokweni sommese wokusika.
7. Isivinini esiphezulu
Uma usika imoto evamile, umsiki kufanele anqunywe ku-60% wejubane elitholakala encwadini.
Isibonelo:Ukwenza ngokwezifiso ukunemba kwemishininge-carbide cutter ibala isivinini se-aluminium enobubanzi obungu-25.4mm kanye nocezu lokusebenza lwensimbi oluthambile oluwububanzi obungu-25.4mm.
Okokuqala, bheka isivinini esinconywayo, I-Speed Speed Steel (HSS) I-Parting Cutter (V-Aluminium ≈ 250 ft/min, V-Steel ≈ 100 ft/min).
Okulandelayo, bala:
N Aluminium [rpm] = 12 × V / (π × D)
=12 ku/ft × 250 ft/min / ( π × 1 phakathi/rpm)
≈ 950 ukuphenduka ngomzuzu
N insimbi [rpm] = 12 × V / (π × D)
=12 ku/ft × 100 ft/min / ( π × 1 phakathi/rpm)
≈ 380 ukuphenduka ngomzuzu
Qaphela: I-N aluminium ≈ 570 rpm kanye ne-N steel ≈ 230 rpm ngenxa yokwengezwa okubhaliwe kwamafutha okusika, okunciphisa isivinini ku-60%. Uyacelwa ukuthi uqaphele ukuthi lawa ngama-maximus futhi ukuphepha kufanele kubhekwe; Ngakho-ke ama-workpiece amancane, kungakhathaliseki imiphumela yokubala, awakwazi ukudlula u-600RPM.
