Eyona njongo iphambili yeprofayile kukuqinisekisa ukuba imilo yecontour yangaphandle yeringi yepiston iyahambelana negophe loxinzelelo eliyiliweyo.

1. Umphezulu wokuphela kokusila ngokurhabaxa: ubude obungenanto bobude = ubude bendandatho yangaphambili yediski yokusika + isibonelelo sokusila esirhabaxa (0.7-0.8 iidiski ezimbini)
I-disc yokusika: ukuphakama kwendandatho yangaphambili ye-disc yokusika = ububanzi be-cutter + 2 × (ukuphakama kwendandatho emva kokugaya okuphakathi + isibonelelo esiphakathi sokugaya);   Ububanzi bemela yokusika ngokuqhelekileyo yi-1.8 ~ 2.2, kwaye isibonelelo sokusila esiphakathi ngokuqhelekileyo si-0.18 (icala eliphindwe kabini)
2. Ubuso bokuphela kokusila obuphakathi: ukuphakama kwesiqingatha sokugqiba + isibonelelo sesiqingatha sokugqiba; Umxhesho ophakathi kokugqiba uphela yi-0.16~0.20 (amacala amabini)
Semi-finish ekupheleni kobuso bokusila: ubude obucolekileyo bokusila + isibonelelo esilungileyo sokusila; I-alloy ring isibonelelo sokusila esihle sithatha i-0.03 ~ 0.035 (icala eliphindwe kabini); I-iron ductile ring ithatha i-0.05 (icala eliphindwe kabini)
3. Gqibezela ubuso bokugqiba ukugaya: thatha isigqibo sokuba unxibe kwaye uphinde ugaye ngokuhambelana nobuchwepheshe bokucubungula
4. Ukukopa imoto: ubukhulu bedayamitha emide
5. Ukusika ukugaya: ubude bokusika
6. Isangqa sangaphakathi esirhabaxa: ukuzimisela kobukhulu be-radial; isibonelelo esidikayo esingaphakathi kwisangqa sobubanzi beradial + isibonelelo esikruqulayo sangaphakathi sesangqa + isibonelelo esilungileyo sokuguqula isangqa sangaphandle. Isibonelelo somatshini wesangqa esingaphakathi esikruqulayo kunye nesangqa esihle esijikayo sangaphandle ngokubanzi yi-0.2mm.
7. Ukulungiswa okurhabaxa kokuvula: i-gap evaliweyo ngokuqhelekileyo yi-0.15-0.35, kunye nobubanzi obungaphakathi be-ring gauge ngokubanzi φd1 (ubungakanani obusisiseko beringi yepiston) + 0.65
8. Gqibezela ukujika isangqa sangaphandle: ubukhulu be-radial be-substrate egqityiweyo + isibonelelo esidikayo sangaphakathi sesangqa + isibonelelo sokuhona sangaphandle; Isibonelelo esikruqulayo sangaphakathi siqhelekile
0.2mm, isibonelelo se-honing ngokubanzi yi-0.03 ~ 0.05mm. Ukuzimisela kwesithuba esivaliweyo: ngesiseko sobukhulu be-trim, faka i-0.05 kumacala aphezulu nangaphantsi.
9. Isangqa sangaphakathi esikruqulayo esicolekileyo: ubungqingqwa beradial bemveliso egqityiweyo-ubukhulu bomaleko wechromium + isibonelelo sokuhomba phambi kokubekwa; ubukhulu bomgca we-chromium bunqunywe yinkqubo, kwaye ayinakubhekisela kuphela kumzobo wemveliso. Isibonelelo sokulungisa phambi kokucwenga sithathwa ngokubanzi njenge-0.05
10. I-engile yangaphandle eChamfering: gabalala yi-0.2X45°, injongo kukuthintela i-chrome plating ekuweni kwi-chrome.
11. Ukugqiba umlomo phambi kokutyalwa: Qinisekisa ngokwesithuba esivaliweyo emva kokusila okuphakathi, umda kwicala elinye lokuvula yi-0.10.
12. Ukuhlolwa phambi kokubekwa
13. Ukuhlonitshwa phambi kokubekwa: isibonelelo secala elinye yi-0.05
14. Qwalasela inkangeleko phambi kokutyabeka
15. I-Chrome plating: i-chrome plating egqitywe ubukhulu be-chrome + isibonelelo sokuhomba emva kokubekwa
16. I-Demagnetization
17. Ukuvulwa kokugaya okuphakathi: Kumiselwa ngokobukhulu bemveliso egqityiweyo, kwaye imfuneko kukuqinisekisa ukuba kukho umda wokuvula ukugaya okulungileyo, kodwa kungabi mkhulu kakhulu. Ngokubanzi, umda we-unilateral yi-0.05 ~ 0.10m
18. Ukuhlonitshwa emva kokubekwa: Umda osecaleni 0.05
19.Hlola inkangeleko emva kokubekwa
20. Ukuvula ukugaya okucokisekileyo: misela ubude bomsesane ngokweemfuno zomzobo wemveliso
21. Ukugaya kwakhona: Qinisekisa ubude bomsesane ngokweemfuno zemizobo yemveliso
22. Umphezulu weWedge wemoto: 1.5 ukusuka kwisangqa sangaphandle, ukuphakama kwesangqa sesiseko 1.061±0.01, i-engile ye-wedge 7 ° 15′±15′
23. Ukugaya i-groove yokumisa: ngokweemfuno zomzobo wemveliso
24. I-oyile yokuhombisa isangqa sangaphandle: Ukuhonjiswa kwe-oyile imizuzwana eli-10 ukuqinisekisa isithuba esivaliweyo kunye nomda osecaleni.
