Kusarudzwa Kwemari Yekudzorera
⑴ Ruregerero rwekudzoreredza Rumbidzo yekudzorera hudzamu hwekuchekwa kwakachengeterwa kudzokorora. Kazhinji, mvumo yekudzorerazve idiki pane mvumo yekudzorerazve kana kufinha. Yakawandisa reming allowance inowedzera kudzvanywa kwekucheka uye kukuvadza reamer, zvichikonzera kushata kwenzvimbo yakagadziriswa. Kana iyo margin yakakurisa, hinge yakakasharara uye hinge yakanaka inogona kupatsanurwa kuve nechokwadi chehunyanzvi zvinodiwa.
Nekune rumwe rutivi, kana mari yebhillet iri diki zvakanyanya, remer inosakara nguva isati yakwana uye haigone kutemwa zvakajairika, uye kushata kwepamusoro kuchave kwakashata. Kazhinji, iyo reming allowance ndeye 0.1 ~ 0.25mm, uye kumakomba makuru edhayamita, mvumo haigone kuva yakakura kupfuura 0.3mm.
Pane chiitiko chinoratidza kuchengetedza ukobvu hwe1 ~ 3% yeiyo remer dhayamita semvumo yekudzosera (dhayamita kukosha). Semuyenzaniso, zvakanyanyo fanira kuwedzera Φ20 reamer ine buri dhayamita inosvika Φ19.6: 20-(20*2/ 100)=19.6 Mitemo yekudzorera inowanzoitwa diki kune zvinhu zvakaoma uye zvimwe zvemuchadenga.
(2) Chiyero chekudya chekugadzirisa zvakare Chiyero chekudya chekugadzirisa zvakare chakakura kudarika chekuchera, kazhinji 2 ~ 3 nguva dzayo. Chinangwa chechiyero chepamusoro chekudya ndechekuita kuti reamer acheke zvinhu panzvimbo yeabrasive material. Nekudaro, iyo roughness Ra kukosha kwekudzokorora kunowedzera nekuwedzera kwehuwandu hwekudya. Kana chiyero chekudya chiri chidiki zvakanyanya, radial friction ichawedzera, uye reamer ichasakara nekukurumidza, zvichikonzera kuti mugadziri azunguze nekukwenya pamusoro pegomba.
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:
CNC Zvishandiso Vagadziri - China CNC Zvishandiso Factory & Suppliers (xinfatools.com)
Standard steel reamer processing steel parts, kuti awane kushata kwepamusoro Ra0.63, chiyero chekudya hachifaniri kudarika 0.5mm / r, yezvikamu zvesimbi yakakandwa, inogona kuwedzerwa kusvika 0.85mm / r.
⑶ Kudzora kumhanya kwe spindle uye huwandu hwekuitazve Zvinhu zvese zvine chekuita nekushata kwepamusoro kwegomba rekudzoreredza, pakati peiyo kumhanya kwekudzokorora kune simba guru. Kana simbi yesimbi inoshandiswa pakugadzirisa zvakare, iri nani roughness Ra0.63; m , Kwepakati kabhoni simbi workpieces, reming speed haifaniri kudarika 5m/min, nokuti yakavakirwa-kumusoro kumucheto hakusi nyore kuitika panguva ino, uye kumhanya hakusi yakakwirira; kana uchigadzira simbi yakakandwa, nekuti machipisi akatsemurwa kuita granular, hapana mupendero wakaunganidzwa uchaumbwa. Edges, saka kumhanya kunogona kuwedzerwa kusvika 8 ~ 10m/min. Kazhinji, iyo spindle yekumhanyisa yekudzokorora inogona kusarudzwa se 2/3 yespindle yekumhanyisa yekuchera pane imwecheteyo chinhu.
Semuyenzaniso, kana drilling spindle speed iri 500r/min, zvine musoro kuseta reming spindle speed pa 2/3 yacho: 500*0.660=330r/min.
Iyo inonzi remer inobhowekana. Fine boring kazhinji ine unilateral margin ye0.03-0.1 uye kumhanya kwe300-1000. Chiyero chekudya chiri pakati pe30-100, zvichienderana nekuti inonzi banga.
