Kusankhidwa kwa Ndalama Zobwezeretsanso

⑴ Chilolezo chobwezanso ndi kuzama kwa kudula kosungidwira kukonzanso. Nthawi zambiri, ndalama zolipirira kukonzanso zimakhala zocheperapo kusiyana ndi zomwe zimalola kukonzanso kapena kusokoneza. Kuchuluka kwa reming allowance kumawonjezera kuthamanga kwa kudula ndikuwononga reamer, zomwe zimabweretsa kuuma kwa malo okonzedwa. Pamene malirewo ali aakulu kwambiri, hinji yolimba ndi hinji yabwino imatha kupatulidwa kuti zitsimikizire zofunikira zaukadaulo.

Kumbali ina, ngati malipiro a billet ndi ochepa kwambiri, reamer amatha kutha msanga ndipo sangadulidwe bwino, ndipo kuuma kwa pamwamba kudzakhala kosauka. Nthawi zambiri, gawo la reming ndi 0.1 ~ 0.25mm, ndipo pamabowo akulu akulu, gawolo silingakhale lalikulu kuposa 0.3mm.

Pali chochitikira chomwe chikuwonetsa kusungitsa makulidwe a 1 ~ 3% ya mainchesi a remer ngati chololeza chowongolera (mtengo wa mita). Mwachitsanzo, ndi koyenera kuwonjezera Φ20 reamer yokhala ndi dzenje lapakati pafupifupi Φ19.6: 20-(20*2/ 100)=19.6 Malire a rereming nthawi zambiri amapangidwa kukhala ang'onoang'ono pazinthu zolimba ndi zida zina zakuthambo.

(2) Mlingo wa chakudya cha reming Mlingo wa chakudya cha reming ndi wokulirapo kuposa wakubowola, nthawi zambiri 2-3 nthawi zake. Cholinga cha mlingo wapamwamba wa chakudya ndi kupanga reamer kudula zinthu m'malo mwa abrasive. Komabe, roughness Ra mtengo wa reming amawonjezeka ndi kuchuluka kwa chakudya. Ngati kuchuluka kwa chakudya kuli kochepa kwambiri, kugundana kwa ma radial kumawonjezeka, ndipo chowongoleracho chimatha mwachangu, zomwe zimapangitsa kuti chowongoleracho chigwedezeke ndikupangitsa kuti pabowolo zikhala molimba.

Zida za Xinfa CNC zili ndi mawonekedwe abwino komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:
CNC Tools Opanga - China CNC Tools Factory & Suppliers (xinfatools.com)

Standard zitsulo reamer processing zigawo zitsulo, kupeza pamwamba roughness Ra0.63, mlingo chakudya sayenera upambana 0.5mm / r, kwa kuponyedwa zitsulo mbali, akhoza ziwonjezeke kwa 0.85mm / r.

⑶ Kubwezeretsanso liwiro la spindle ndi kuchuluka kwa kukonzanso Zinthu zonse zimakhudza kukhwinyata kwa dzenje lobwezeretsanso, pomwe liwiro lobwezeretsa limakhudza kwambiri. Ngati chowotcha chitsulo chimagwiritsidwa ntchito pokonzanso, roughness yabwino Ra0.63; m , Pakuti sing'anga carbon zitsulo workpieces, liwiro reming sayenera upambana 5m/mphindi, chifukwa anamanga m'mphepete si zophweka kuchitika pa nthawi ino, ndipo liwiro si mkulu; pokonzanso chitsulo chosungunuka, chifukwa tchipisi taphwanyidwa kukhala granular, palibe m'mphepete mwake womwe udzapangike. M'mphepete, kotero liwiro likhoza kuwonjezeka kufika 8 ~ 10m / min. Nthawi zambiri, liwiro la spindle la reming litha kusankhidwa ngati 2/3 ya liwiro la spindle pobowola pazinthu zomwezo.

Mwachitsanzo, ngati pobowola spindle liwiro ndi 500r/mphindi, ndi zomveka kukhazikitsa reaming spindle liwiro pa 2/3: 500 * 0.660 = 330r/mphindi.

Zomwe zimatchedwa remer kwenikweni ndizotopetsa. Fine boring nthawi zambiri imakhala ndi malire a 0.03-0.1 ndi liwiro la 300-1000. Mlingo wa chakudya uli pakati pa 30-100, kutengera ngati umatchedwa mpeni.
