Uburhabaxa boMphezulu kwiinkqubo ezahlukeneyo zokusika

Uburhabaxa bomphezulu bubhekiselele kwizitenxo kunye nokutenxa kumongo womphezulu wezinto emva kokuba ziphantsi kwenkqubo yokusika. Yiparameter ebalulekileyo echaphazela ngokuthe ngqo ukusebenza, ukuqina, kunye nesibheno sobuhle bemveliso yokugqibela. Ukuphumeza uburhabaxa obufunwayo bomgangatho ofunekayo wokuqinisekisa ukufaneleka ngokufanelekileyo, ukunciphisa ukukhuhlana, kunye nokuphucula ukusebenza ngokubanzi kwezinto ezinomatshini.

1. Ukujika

Ukujika yinkqubo yomatshini apho i-workpiece ijikeleza ngelixa isixhobo sihamba ngokulandelelana okanye silandela indlela egobileyo ngaphakathi kwendiza ukusika izinto. Lo msebenzi wenziwa ngokwesiqhelo kwilathe ukuya kumatshini umphezulu wangaphandle kunye nangaphakathi wecylindrical, ubuso besiphelo, umphezulu weconical, umphezulu owenziweyo, kunye nemisonto.

Uburhabaxa obuqhelekileyo bomphezulu wokuguqula imisebenzi ukusuka kwiRa 1.6 ukuya kwi-0.8 μm.

• Ukujika okurhabaxa kujolise ekufezekiseni ukusebenza kakuhle okuphezulu ngokusebenzisa ubunzulu obukhulu bemilinganiselo yokusikwa kunye nokutya ngaphandle kokunciphisa isantya sokusika, okubangela ubuninzi bomhlaba weRa 20 ukuya kwi-10 μm;
• Isiqingatha-sokugqiba kunye nokugqiba ukujika sebenzisa isantya esiphezulu kunye namazinga amancinci okutya kunye nobunzulu bokusika, ukuphumeza uburhabaxa bomphezulu be-Ra 10 ukuya kwi-0.16 μm;
• Iileyile ezichanekileyo eziphezulu kunye nezixhobo zedayimani eziphuculweyo ziyakwazi ukuvelisa iindawo zetsimbi ezingenayo i-ferrous kunye noburhabaxa bomhlaba we-Ra 0.04 ukuya kwi-0.01 μm ngexesha lemisebenzi yokugqiba ngesantya esiphezulu.

2. Ukugaya

Ukugaya kubandakanya ukusebenzisa i-cutter multi-fluted ejikelezayo ukuze kususwe izinto ezivela kwi-workpiece, ukubonelela ngendlela efanelekileyo yeendiza zomatshini, i-grooves, iindawo ezahlukeneyo ezenziweyo (ezifana ne-splines, gears, kunye neentambo), kunye neemilo ezikhethekileyo zokubumba. Kuxhomekeka ekubeni isalathiso sesantya sesindululo esiphambili siyahambelana okanye siyachasa isalathiso sesondlo sesixhobo sokusebenza, ukungqusha kungahlelwa njengokusila okuqhelekileyo (phezulu) okanye ukukhwela (ezantsi) kokungqusha.

Uburhabaxa obuqhelekileyo bomphezulu wokugaya buhluka ukusuka kwiRa 6.3 ukuya kwi-1.6 μm.

• Ukungqusha kuphumela kuburhabaxa bomphezulu beRa 5 ukuya kuma-20 μm;
• Semi-finishing milling ifezekisa uburhabaxa bomphezulu beRa 2.5 ukuya kwi-10 μm;
• Ukugqiba ukugaya kuvelisa uburhabaxa bomphezulu beRa 0.63 ukuya kwi-5 μm.

3. Ukusila

Ukugaya yinkqubo yomatshini echanekileyo esebenzisa iinkozo ezinqabileyo okanye izixhobo zokususa izinto ezingaphezulu kwi-workpiece, esetyenziswa ngokubanzi kwimveliso yomatshini.

Ukusila ngokuqhelekileyo kusetyenziselwa ukugqiba isiqingatha kunye nokugqiba imisebenzi, kunye noburhabaxa obuqhelekileyo bomgangatho ukusuka kwi-Ra 1.25 ukuya kwi-0.16 μm.

• Ukusila ngokuchanekileyo kubangela uburhabaxa bomphezulu beRa 0.16 ukuya ku-0.04 μm;
• Ukugaya okuchanekileyo kwe-Ultra kunokufezekisa uburhabaxa bomhlaba we-Ra 0.04 ukuya kwi-0.01 μm;
• Ukuqhotsa okanye ukupolisha kunokuvelisa umphezulu ogqitywe kakuhle kuneRa 0.01 μm.

Uburhabaxa bomphezulu bamacandelo oomatshini bunempembelelo enkulu kwimizi-mveliso yokuvelisa kunye nobunjineli. Ichaphazela ngokuthe ngqo ukusebenza, ukusebenza, kunye nokuthembeka kwamalungu oomatshini, izixhobo, kunye neemveliso zabathengi. Ngokuqonda ubudlelwane phakathi kweenkqubo zokusika kunye noburhabaxa bomphezulu, iinjineli kunye nabavelisi banokuphucula iinkqubo zabo zokuvelisa, ukunciphisa inkunkuma yezinto eziphathekayo, kunye nokuhambisa iimveliso eziphezulu kwimarike.
