Kushata Kwepamusoro muMaitirwo Akasiyana-siyana Ekucheka

Surface roughness (Surface roughness) zvinoreva kusarongeka uye kutsauka kwechimiro chepamusoro chechinhu mushure mekunge chaitwa kucheka. Iyo yakakosha paramende inobata zvakananga kushanda, kusimba, uye kunaka kukwezva kwechigadzirwa chekupedzisira. Kuwana kukwasharara kwaunoda kwakakosha kuti uve nechokwadi chakakodzera, kudzikisira kukweshera, uye kusimudzira kuita kwese kwezvakagadzirwa zvinhu.

1. Kutendeuka

Kutendeuka inzira yekugadzira iyo iyo workpiece inotenderera apo chishandiso chinofamba zvine mutsetse kana kutevera nzira yakakombama mukati mendege kucheka zvinhu. Kuvhiya uku kunowanzoitwa palathe kumuchina wekunze uye wemukati cylindrical nzvimbo, kupera zviso, conical nzvimbo, akaumbwa nzvimbo, uye shinda.

Iyo yakajairwa pamusoro pekukasharara kwekushandura mashandiro kubva kuRa 1.6 kusvika 0.8 μm.

• Kushandura kwakakasharara kunovavarira kuwana hunyanzvi hwepamusoro nekushandisa kudzika kwakakura kwekucheka uye kudya kwemazinga pasina kudzikisa kumhanya kwekucheka, zvichikonzera kushata kwepamusoro kweRa 20 kusvika 10 μm;
• Semi-kupedzisa uye kupedzisa kutendeuka shandisa kumhanya kwepamusoro nediki diki rekudya uye kudzika kwekucheka, kuwana roughness yeRa 10 kusvika 0.16 μm;
• High-precision lathes ane maturusi edhaimani akakwenenzverwa anogona kugadzira simbi isina-ferrous ine roughness yepamusoro yeRa 0.04 kusvika 0.01 μm panguva yekumhanya-mhanya kupedzisa mabasa.

2. Kugaya

Kugaya kunosanganisira kushandisa inotenderera yakawanda-fluted cutter kubvisa zvinhu kubva paworkpiece, ichipa nzira inoshanda yekugadzira ndege, grooves, akasiyana akaumbwa nzvimbo (senge splines, giya, uye shinda), uye akakosha maumbirwo e mold. Zvichienderana nekuti danho rekutanga rekufambisa rinoenderana here kana kupikisa gwara rekudya, kugayo kunogona kuverengerwa seyakajairika (kumusoro) kugaya kana kukwira (pasi) kugaya.

Yakajairika milling pamusoro roughness inosiyana kubva Ra 6.3 kusvika 1.6 μm.

• Kugaya kwakashata kunoguma nekukasharara kwepamusoro kweRa 5 kusvika ku20 μm;
• Semi-kupedza milling inobudirira pamusoro roughness yeRa 2.5 kusvika 10 μm;
• Kupedza kugaya kunopa hukasha hwepamusoro hweRa 0.63 kusvika 5 μm.

3. Kukuya

Kukuya ndeye chaiyo machining maitiro anoshandisa abrasive zviyo kana maturusi kubvisa yakawandisa zvinhu kubva paworkpiece, inoiswa zvakanyanya mukugadzira michina.

Kukuya kunowanzo shandiswa semi-kupedzisa uye kupedzisa maoperation, ane yakajairika pamusoro roughness kubva Ra 1.25 kusvika 0.16 μm.

• Kunyatsogaya kunoguma nekukasharara kwepamusoro kweRa 0.16 kusvika 0.04 μm;
• Ultra-chaiyo kugaya inogona kuwana roughness pamusoro Ra 0.04 kusvika 0.01 μm;
• Kurovera kana kupukuta kunogona kuburitsa kupera kwepamusoro kupfuura Ra 0.01 μm.

Iko kushata kwepamusoro kwezvikamu zvemuchina kune zvinosvika kure kune maindasitiri ekugadzira uye einjiniya. Iyo inobata zvakananga kushanda, kuita, uye kuvimbika kwemechini zvikamu, maturusi, uye zvigadzirwa zvevatengi. Nekunzwisisa hukama pakati pekucheka maitiro uye kushata kwepasi, mainjiniya nevagadziri vanogona kukwidziridza maitiro avo ekugadzira, kuderedza kutambisa zvinhu, uye kuendesa zvigadzirwa zvepamusoro kumusika.
