I-Cylindrical Grinding & Internal Grinding
Ukugaya Cylindrical
Ikakhulukazi yenziwa kumshini wokugaya oyicylindrical ukugaya isilinda sangaphandle, ikhoni yangaphandle kanye nobuso bokuphela kwehlombe le-shaft le-shaft workpiece. Ngesikhathi sokugaya, i-workpiece ijikeleza ngesivinini esiphansi. Uma i-workpiece ihamba ngobude futhi ngokuphindaphindiwe ngesikhathi esifanayo, futhi isiphambano sesondo lokugaya siphakela ucezu lokusebenza ngemva kokushaywa ngakunye noma okuphindwe kabili kokunyakaza kwe-longitudinal, kubizwa ngokuthi indlela yokugaya i-longitudinal.
Uma ububanzi besondo lokugaya bukhulu kunobude bomhlaba ophansi, i-workpiece ngeke ihambe isikhathi eside ngesikhathi sokugaya, kodwa isondo lokugaya lizoqhubeka nokuwela okuphakelayo okuhlobene nendawo yokusebenza, ebizwa ngokuthi i-cut in grinding. Ngokuvamile, ukusebenza kahle kokusika ekugayeni kuphakeme kunokugaya i-longitudinal. Uma isondo lokugaya lisikwa libe indawo ebunjiwe, indlela yokugaya ingasetshenziselwa umshini ongaphandle owenziwe.
Ukugaya Kwangaphakathi
Isetshenziselwa ikakhulukazi ukugaya izimbobo ze-cylindrical (Fig. 2), izimbobo ezinama-tapered kanye nezindawo zokugcina zembobo ze-workpieces ku-grinder yangaphakathi, i-universal cylindrical grinder kanye ne-coordinate grinder. Ngokuvamile, indlela yokugaya i-longitudinal iyamukelwa. Lapho ugaya indawo yangaphakathi eyenziwe, indlela yokugaya ingasetshenziswa.
Lapho ugaya imbobo yangaphakathi ku-grinder ye-coordinate, i-workpiece igxiliwe ku-workbench, futhi isondo lokugaya lijikeleza ngesivinini esikhulu, kodwa futhi lenza ukunyakaza kweplanethi ezungeze umugqa ophakathi wembobo yokugaya. Ekugayeni kwangaphakathi, isivinini sokugaya ngokuvamile singaphansi kuka-30 m/s ngenxa yobubanzi obuncane besondo lokugaya.
Ukugaya Okungaphezulu
Isetshenziselwa ikakhulukazi ukugaya indiza kanye ne-groove ku-surface grinder. Kunezinhlobo ezimbili zokugaya okungaphezulu: ukugaya okuzungezile kubhekisela ekugayeni nge-cylindrical surface yesondo lokugaya (Umfanekiso 3). Ngokuvamile, i-spindle surface grinder evundlile isetshenziswa. Uma isondo lokugaya elibunjiwe lisetshenziswa, izindawo ezimise okwehlukene zingabuye zenziwe ngomshini; Ukugaya ubuso ngesondo lokugaya kubizwa ngokuthi ukugaya ubuso, futhi i-vertical surface grinder ngokuvamile isetshenziswa.
