I-1, ukuthengwa kwabathengisi be-CNC blade baye baxinzezeleka ngenxa yokugqoka i-CNC blades, i-chips yokugqoka i-abrasive okanye ezinye iindawo ezincinci eziqinileyo ebusweni bomsebenzi (njenge-carbide, i-oxide, njl.) kunye nokungcola (okufana nesihlabathi, i-oxide , njl.), kunye nokunamathela kwi-debris ye-chip tumor, njl., i-mechanical wear ebangelwa yi-grooves eqingqwe phezu kobuso beCNC.Kwizixhobo zetsimbi ezikhawulezayo ezinesantya esiphantsi esilindelekileyo kunye nobushushu obuphantsi bokusika (njenge-broach, die, tap, njl.), yeyona nto ibaluleke kakhulu yokugqoka.
2. Ukunxiba okuncamathelayo kubumba unxibelelwano lomphezulu olutsha phantsi koxinzelelo olulungileyo kunye nobushushu bokusika phakathi kobuso besixhobo sangasemva seblade yeCNC kunye nomphezulu wesixhobo sokusebenza kunye nobuso besixhobo sangaphambili seblade yeCNC kunye neetshiphusi.Xa umphezulu woqhagamshelwano ufikelela kumgama we-interatomic, i-adsorption bond phenomenon yenzeke.Indawo edibeneyo isikwa ngokuthe ngcembe kwaye ikrazulwe yi-workpiece okanye iichips, kwaye umphezulu weCNC blade uya kuvelisa ukunxiba okuncamathelayo.Ukugqoka i-adhesive sesinye sezizathu eziphambili zokugqoka i-carbide ye-cemented xa usika kwisantya esiphakathi kunye nesezantsi.
3, ukunxitywa kokusasazwa kubushushu obuphezulu, uxinzelelo oluphezulu, i-CNC blade imathiriyeli kunye nesixhobo sokusebenza esikwimo eqinileyo yezinto ezithile zeekhemikhali kwidiffusion encinci, oko kukuthi, i-tungsten carbide Ti, w, Co kunye nezinye izinto ezinje ngentsimbi, kunye workpiece Fe, C kunye nezinye izinto ukuya CNC blade diffusion, okubangela ubulukhuni umphezulu isixhobo, ukwehla ukufunda ngamandla, ukwanda brittleness, isixhobo ukunxiba ukuqina.Oku kwaziwa njengokunxitywa kokusasazwa, kwaye ukunxitywa kokusasazwa sesinye sezizathu eziphambili zokunxitywa kwezixhobo zokusika i-carbide ngesamente kumaqondo obushushu aphezulu kwangoko (800″900°C).
I-4, ngokubanzi i-W, izinga lokusasazwa kwe-Co likhawuleza kune-Ti, i-Ta, ngoko ke ukusebenza kweqondo lokushisa eliphezulu kwe-YT yeklasi ye-cemented carbide ingcono kuneklasi ye-YG.Ukutshintshwa kwesigaba sokugqoka Xa usika ngezixhobo zetsimbi ezikhawulezayo, xa ubushushu bokusika budlula ubushushu bokutshintsha kwesigaba (550 "600 ° C), isakhiwo se-metallographic ye-CNC blade siya kutshintsha, ukwenzela ukuba ubunzima buya kuncipha kwaye ukugqoka kuya kukhawuleza. , ngoko ke ukutshintshwa kwesigaba sinxibe esinye sezizathu eziphambili zokugqoka i-blade ye-CNC yensimbi ephezulu.Ukunxitywa kweekhemikhali Kwiqondo lobushushu elithile, imidiya ejikeleze indawo yokusika, njengomoya, ulwelo lokusika, njl. njl., isabela ngokwekhemikhali ngezinto zesixhobo ukwenza iikhompawundi ezikhululekileyo nezibuthathaka.Ezi khompawundi kulula ukugawulwa kwaye workpiece abrasion kude, kukhokelela CNC incakuba ukunxitywa.
