CNC machining iinxalenye zeplastiki

NangonaCNC Machiningyamacandelo eplastiki kulula ukugawula, nayo ineengxaki ezithile, ezifana nokuguqulwa lula, ukungahambi kakuhle kwe-thermal, kunye nokukhathazeka kakhulu kumandla okusika, ukuchaneka kwayo kokucubungula akuqinisekiswanga, kuba kulula ukuchatshazelwa ngubushushu, kwaye kulula ukuvelisa i-deformation kwi-processing, kodwa sineendlela zokujongana nayo.CNC machining iinxalenye zeplastiki:

1. Ukukhetha isixhobo:

• Njengoko imathiriyeli yeplastiki ithambile, kufuneka kukhethwe izixhobo ezibukhali. Umzekelo, kwiiprototypes zeplastiki ze-ABS, izixhobo ze-carbide ezinemiphetho yokusika ezibukhali zinokunciphisa ngokufanelekileyo iinyembezi kunye ne-burrs ngexesha lokucubungula.

•Khetha izixhobo ezisekelwe kubume kunye neenkcukacha ezintsonkothileyo zeprototype. Ukuba iprototype inezakhiwo ezibuthathaka zangaphakathi okanye izikhewu ezimxinwa, ezi ndawo kuya kufuneka zicocwe ngoomatshini kusetyenziswa izixhobo ezincinci ezifana ne-diameter encinci ye-ball end mill.

2. Ukusika useto lweparamitha:

•Isantya sokusika: Indawo yokunyibilika yeplastiki iphantsi kakhulu. Ukusika ngokukhawuleza kunokubangela ukuba iplastiki ishushu kakhulu kwaye inyibilike. Ngokubanzi, isantya sokusika sinokukhawuleza kuneso sokwenza izixhobo zentsimbi, kodwa kufuneka zihlengahlengiswe ngokusekelwe kuhlobo oluthile lweplastiki kunye neemeko zesixhobo. Ngokomzekelo, xa kusetyenzwa iiprototypes ze-polycarbonate (PC), isantya sokusika singasetwa malunga ne-300-600m / min.

• Isantya sokutya: Isantya sokutya esifanelekileyo sinokuqinisekisa umgangatho wokuqhuba. Isantya sokutya esigqithisileyo sinokubangela ukuba isixhobo sithwale amandla okusika ngokugqithisileyo, okukhokelela ekuncipheni komgangatho womphezulu weprototype; umyinge wesondlo omncinci kakhulu uya kunciphisa ukusebenza kakuhle. Kwiiprototypes zeplastiki eziqhelekileyo, isantya sokutya singaba phakathi kwe-0.05 - 0.2 mm / izinyo.

• Ukusika ubunzulu: Ubunzulu bokusika akufunekanga bube nzulu kakhulu; Ngaphandle koko, imikhosi emikhulu yokusika iya kuveliswa, enokuthi iguqule okanye iqhekeze iprototype. Ngaphantsi kweemeko eziqhelekileyo, kucetyiswa ukuba ubunzulu bokusika enye kulawulwa phakathi kwe-0.5 - 2mm.

3. Ukukhethwa kwendlela yokubamba:

•Khetha iindlela ezifanelekileyo zokubamba ukuthintela ukonakalisa umgangatho weprototype. Izinto ezithambileyo ezifana neepads zerabha zingasetyenziswa njengomaleko woqhagamshelwano phakathi kwe-clamp kunye neprototype ukuthintela umonakalo obambekayo. Umzekelo, xa ucinezela iprototype kwi-vise, ukubeka iipads zerabha emihlathini akugcini nje ukuqinisa iprototype ngokukhuselekileyo kodwa ikhusela umphezulu wayo.

•Xa ubamba, qinisekisa ukuzinza kweprototype ukuthintela ukufuduka ngexesha lokucubungula. Kwiiprototypes ezinokwakheka ngokungaqhelekanga, ukulungiswa kwesiko okanye ukudibanisa okudibeneyo kungasetyenziselwa ukuqinisekisa indawo yabo esisigxina ngexesha lokucubungula.

4. Ukwenziwa kwesicwangciso solandelelwano:

• Ngokubanzi, umatshini orhabaxa wenziwa kuqala ukuze kususwe uninzi lwezibonelelo, kushiyeke malunga ne-0.5 – 1 mm yesibonelelo sokugqitywa. I-roughing inokusebenzisa iiparamitha ezinkulu zokusika ukuphucula ukusebenza kakuhle.

•Xa ugqiba, kufuneka kunikwe ingqwalasela ekuqinisekiseni ukuchaneka komgangatho kunye nomgangatho womphezulu weprototype. Kwiiprototypes ezineemfuno eziphezulu zomgangatho ophezulu, inkqubo yokugqibela yokugqiba inokucwangciswa, njengokugaya ngesantya esincinci sokutya, ubunzulu obuncinci bokusika, okanye ukusebenzisa izixhobo zokupolisha kunyango lwangaphezulu.

5. Ukusetyenziswa kwesipholisi:

•Xa ulungisa iiprototypes zeplastiki, lumka xa usebenzisa into yokupholisa. Ezinye iiplastiki zinokusabela ngokwekhemikhali kunye nesipholisi, ngoko ke khetha uhlobo olufanelekileyo lwesipholisi. Umzekelo, kwiiprototypes zepolystyrene (PS), kuphephe ukusebenzisa izinto zokupholisa ezinezinyibilikisi ezithile eziphilayo.

•Eyona misebenzi iphambili yesipholisi kukupholisa nokuthambisa. Ngexesha lenkqubo yomatshini, isisipholisi esifanelekileyo sinokuthoba ubushushu bokusika, sinciphise ukunxiba kwesixhobo, kwaye siphucule umgangatho womatshini.
