Ukukhethwa kweeBlades zokusika zeMetallographic Cutters

Xa usebenzisa isixhobo sokusika esichanekileyo ukusika izinto zokusebenza, kuyimfuneko ukukhetha iiblade zokusika ezihambelana neempawu zezinto zokusebenza ngokusekelwe kwizinto zaso ezahlukeneyo, ukuze kufezekiswe iziphumo zokusika ezisebenzayo. Ngezantsi, siza kuxoxa ngokukhethwa kweeblade zokusika kwiimbono ezintathu:

1. Ukhetho olusekelwe kwiipropati zezinto ezibonakalayo

1) Kwizinto zesinyithi ezifana nentsimbi, isinyithi, kunye nee-alloys, kufuneka kusetyenziswe iiblade zokusika ezine-resin-bond. Ubukhulu bazo buhlala buphakathi kwe-1-2 mm, nto leyo efanelekileyo ekusikeni ngokufanelekileyo kwezinto zesinyithi ezifana nentsimbi eqinileyo. Indawo echaphazeleka bubushushu ikwasebenza kwiimeko zokusika ngokuchanekileyo ezifana nohlalutyo lwe-metallographic. Ukongeza, umonakalo wokusika ungancitshiswa ngempumelelo ngokulungelelanisa izinga lokutya.

2) Kwizinto ezingomelelanga ezingeyontsimbi ezifana neeseramikhi neglasi, kufuneka iiblade zokusika iidayimani. Ezi blade zinobunzima obuphezulu kunye nokuqhuba kakuhle kobushushu, nto leyo enokunciphisa umngcipheko wokonakala kobushushu.

3) Kwimizi-mveliso ye-semiconductor, i-integrated circuit, kunye ne-PCB, ii-blades zedayimani ezicokisekileyo kakhulu zisetyenziswa kakhulu kulawulo lomgangatho kunye nohlalutyo lokusilela.

2. Ukukhetha Ngokusekelwe kwiimfuno zokusika umphezulu kunye neemfuno zokusebenza kakuhle

1) Xa umsebenzi ungadingi kuguqulwa kwaye ucoceke kakhulu kumphezulu, khetha iiblade ezibhityileyo zokusika (ubukhulu: 0.3-1.0 mm). Ezi blade zinciphisa umaleko womonakalo wokusika kwaye zenze kube lula iinkqubo zokusila ezilandelayo.

2) Xa kufuneka isantya esiphezulu sokusika kunye nokusebenza kakuhle, khetha iiblade zokusika eziqinileyo (ubukhulu: 1.2-3.0 mm). Ezi blade ziqinile kakhulu, azilula ukuziqhekeza, kwaye zifanelekile ukusika ibhetshi.

3.Ukhetho olusekelwe kwi-Workpiece Hardness

Ubunzima besixhobo somsebenzi bumisela ngokuthe ngqo ukukhethwa kwezinto zeblade yokusika. Okwangoku, kuyimfuneko ukuqwalasela iimfuno ezikhankanyiweyo apha ngasentla zeeblade ezibhityileyo okanye ezityebileyo (ngokusekwe kumgangatho/ukusebenza kakuhle komphezulu). Okukhona ubunzima besixhobo somsebenzi buphezulu, kokukhona kufuneka iblade yokusika iqine kwaye iguge.

1) Izinto zokusebenza ezinobunzima obuphezulu (＞HRC 50, umz., intsimbi eqinileyo, i-carbide eqinisiweyo, intsimbi enekhabhoni ephezulu)

Iiblade zokusika ezifanelekileyo: Iiblade zokusika zedayimani okanye iiblade zokusika ze-cubic boron nitride (CBN)

Ubukhulu obucetyiswayo: Eyona nto iphambili inikwa iiblade ezityebileyo (1.2-3.0 mm). Zinobulukhuni obuphezulu kunye nokumelana nokuguguleka, nto leyo enokuthintela ukuqhekeka ngexesha lokusika. Izinto zokusebenza ezinobunzima obuphezulu zidla ngokuguguleka iiblade eziqhelekileyo zokusika, ngoko ke izinto ezimelana nokuguguleka zinokuqinisekisa ukusebenza kakuhle kokusika; isakhiwo esityebileyo sifanelekile ekusikeni umthwalo omkhulu.

2) Izinto zokusebenza ezinobunzima obuphakathi (HRC 30-50, umz., intsimbi yekhabhoni eqhelekileyo, isinyithi esityhidiweyo, intsimbi engatyiwayo)

Iiblade zokusika ezifanelekileyo: Iiblade zokusika zedayimani ezibotshelelwe nge-resin okanye iiblade zokusika ze-alumina ezikumgangatho ophezulu

Ubukhulu obucetyiswayo: Ukhetho oluguquguqukayo — khetha iiblade ezibhityileyo (0.3-1.0 mm) ukuze kucoceke kakhulu umphezulu, okanye iiblade ezibhityileyo (1.2-3.0 mm) ukuze kusetyenzwe ngebhetshi. Ekubeni ubunzima bezinto buphakathi, iiblade eziqhelekileyo zokusika ezingagugiyo zinokuhlangabezana neemfuno zokusika, kwaye iiblade ezibhityileyo/ezityebileyo zinokulinganiswa ngokomgangatho womphezulu okanye iimfuno zokusebenza kakuhle.

3) Izinto zokusebenza ezinobunzima obuphantsi (

Iiblayidi zokusika ezifanelekileyo: Iiblayidi zokusika ze-alumina eziqhelekileyo okanye iiblayidi zokusika zedayimani ezibhityileyo

Ubukhulu obucetyiswayo: Kunikwa ingqalelo kwiiblade ezibhityileyo (0.3-0.8 mm); iiblade eziyi-1.0 mm zingakhethwa kwezinye izinto. Iiblade zokusebenzela ezinobunzima obuphantsi zinokubambeka kwizixhobo kwaye ziguquguquke; iiblade zokusika ezincinci zinciphisa indawo yokudibana, ziphephe ukunamathela kwizixhobo kunye nomonakalo wezixhobo zomsebenzi. Izixhobo eziqhelekileyo zeeblade zokusika zanele ukuhlangabezana neemfuno zokusika.

Amanqaku okugqibela okukhetha iBlade yokuSika:

Isiphumo sokusika kunye nobomi benkonzo yeeblade zokusika ezisetyenziswa ngokubanzi ziya kuncipha kakhulu xa zisetyenziswa kwizixhobo ezithile.

I-blade yokusika kufuneka ikhethwe ngokwendlela yokusika i-metallographic esetyenziswayo. Umzekelo, kuphephe ukusebenzisa ii-blade zokusika eziqinileyo kwii-cutters ezinamandla aphantsi kangangoko kunokwenzeka, kuba oku kunokubangela ukuba i-motor igcwale kakhulu okanye i-cutting blade iphuke.
