Vickers ubulukhuni HV (ikakhulu kumlinganiselo wokuqina komphezulu)
Sebenzisa i-indenter yesikweri sedayimane esinomthwalo omkhulu we-120 kg kunye ne-engile ephezulu ye-136 ° ukucinezela kumphezulu we-material kunye nokulinganisa ubude be-diagonal ye-indent. Le ndlela ifanelekile ukuvavanya ubulukhuni bezinto zokusebenza ezinkulu kunye neengqimba ezinzulu zomhlaba.
Ubunzima beLeeb HL (umvavanyi wobulukhuni ophathwayo)
Indlela yokuqina kaLeeb isetyenziselwa ukuvavanya ubulukhuni bemathiriyeli. Ixabiso lobulukhuni be-Leeb limiselwa ngokulinganisa isantya sokubuyela kwakhona somzimba wempembelelo yenzwa yokuqina ngokunxulumene nesantya sempembelelo kumgama we-1mm ukusuka kumphezulu wesixhobo sokusebenza ngexesha lenkqubo yempembelelo, kwaye ke uphinda-phinda lo mlinganiselo nge-1000.
Izinto eziluncedo:Umvavanyi wobulukhuni be-Leeb, ngokusekelwe kwithiyori yobulukhuni be-Leeb, uye waziguqula iindlela zokuvavanya ubulukhuni besintu. Ubungakanani obuncinci benzwa yobunzima, obufana nepeni, buvumela ukuvavanywa kobunzima obubambe ngesandla kwizinto zokusebenza kwiindlela ezahlukeneyo kwindawo yokuvelisa. Esi sikhundla sinzima kwabanye abavavanyi bobulukhuni bedesktop ukuba batshatise.
Kukho izixhobo ezahlukeneyo zokwenza oomatshini, kuxhomekeke kuhlobo lwemathiriyeli esetyenzwa ngayo. Izixhobo ezisetyenziswa ngokuqhelekileyo zikhohlo, zixhomekeke ekunene, kwaye ziphakathi, njengoko kuboniswe kumfanekiso ongezantsi, ngokusekelwe kuhlobo lomphathi owenziwe ngoomatshini. Ukongezelela, izixhobo ze-tungsten ze-carbide ezineengubo eziphezulu zokushisa zingasetyenziselwa ukusika isinyithi okanye izinto zokunxiba.
2. Ukuhlolwa kwesixhobo
Hlola ngononophelo imela yokusika ngaphambi kokuba uyisebenzise. Ukuba usebenzisa iincakuba zokusika ezikwisantya esiphezulu (high-speed steel (HSS)), lola imela ukuqinisekisa ukuba ibukhali. Ukuba usebenzisa imela yokuhlukanisa i-carbide, khangela ukuba i-blade ikwimeko efanelekileyo.
3. Ukwandisa ukuqina kofakelo lomese wokusika
Ukuqina kwesixhobo kunyuswa ngokunciphisa ubude besixhobo esiphuma ngaphandle kwe-turret. Iidayamitha ezinkulu okanye ii-workpieces ezomeleleyo kufuneka zihlengahlengiswe amaxesha amaninzi xa isixhobo sisika kwimathiriyeli ngexesha lokwahlukana.
Ngesizathu esifanayo, ukuhlukana kuhlala kwenziwa ngokusondeleyo kwi-chuck ngokusemandleni (ngokuqhelekileyo malunga ne-3mm) ukwenzela ukunyusa ukuqina kwenxalenye ngexesha lokuhlukana, njengoko kuboniswe kumfanekiso.
4. Lungelelanisa isixhobo
Isixhobo kufuneka silungelelaniswe ngokugqibeleleyo ne-x-axis kwileyile. Iindlela ezimbini eziqhelekileyo zokuphumeza oku kukusebenzisa ibhloko yokuseta isixhobo okanye igeyiji yokucofa, njengoko kubonisiwe kumfanekiso.
Ukuqinisekisa ukuba i-knife yokusika i-perpendicular phambi kwe-chuck, ungasebenzisa ibhloko ye-gauge kunye ne-parallel surface. Okokuqala, khulula i-turret, emva koko ulungelelanise umda we-turret kunye nebhloko ye-gauge, kwaye ekugqibeleni, phinda uqinise i-screws. Qaphela ukuba igeyiji ingawi.
Ukuqinisekisa ukuba isixhobo si-perpendicular kwi-chuck, ungasebenzisa kwakhona i-dial gauge. Namathisela i-dial gauge kwintonga yokudibanisa kwaye uyibeke kumzila (musa ukuslayida kunye nomzila; yilungise endaweni). Yalatha umfowunelwa kwisixhobo kwaye uyihambise ecaleni kwe-x-axis ngelixa ujonga utshintsho kwigeyiji yokucofa. Impazamo engu-+/-0.02mm yamkelekile.
5. Jonga ubude besixhobo
Xa usebenzisa izixhobo kwiilathesi, kubalulekile ukujonga kwaye ulungelelanise ukuphakama kwemela yokuqhawula ukuze isondele kumbindi we-spindle kangangoko kunokwenzeka. Ukuba isixhobo sokuqhawula asikho kwi-centerline ethe nkqo, asiyi kunqunyulwa ngokufanelekileyo kwaye inokonakala ngexesha lomatshini.
Njengezinye iimela, iimela zokuqhawula kufuneka zisebenzise inqanaba lelathe okanye irula ukuze incam ibe kumbindi othe nkqo.
6. Yongeza ioli yokusika
Xa usebenzisa imoto eqhelekileyo, ungasebenzisi ukutya okuzenzekelayo, kwaye qiniseka ukusebenzisa ioli eninzi yokusika, kuba inkqubo yokusika ivelisa ubushushu obuninzi. Ngoko ke, kuba shushu kakhulu emva kokusika. Faka ioli yokusika ngaphezulu kwincam yomese wokusika.
7. Isantya somphezulu
Xa usika kwimoto jikelele, i-cutter kufuneka inqunywe ngokuqhelekileyo kwi-60% yesantya esifunyenwe kwincwadana.
Umzekelo:Custom precision machiningnge-carbide cutter ibala isantya se-25.4mm ububanzi be-aluminium kunye ne-25.4mm ububanzi bentsimbi yokusebenzela.
Okokuqala, khangela isantya esinconywayo, i-Speed Speed Speed Steel (HSS) I-Parting Cutter (V-Aluminium ≈ 250 ft / min, V-Steel ≈ 100 ft / min).
Okulandelayo, bala:
N Aluminiyam [rpm] = 12 × V / (π × D)
=12 kwi/ft × 250 ft/min / ( π × 1 kwi/rpm)
≈ 950 revolutions ngomzuzu
N intsimbi [rpm] = 12 × V / (π × D)
=12 ngaphakathi/ft × 100 ft/min / ( π × 1 kwi/rpm)
≈ 380 revolutions ngomzuzu
Qaphela: I-N aluminium ≈ 570 rpm kunye ne-N steel ≈ 230 rpm ngenxa yokongezwa kwe-manual yokusika ioli, okunciphisa isivinini kwi-60%. Nceda uqaphele ukuba ezi zizinto eziphezulu kwaye ukhuseleko kufuneka luthathelwe ingqalelo; Iiworkpieces ezincinci ke ngoko, nokuba zithini na iziphumo zokubala, azinakugqitha kuma-600RPM.
