Kungani Izingxenye Zomshini We-Precision Granite Zimbozwe Ngamafutha Ngaphambi Kokuthunyelwa

I-granite eqondile ibilokhu iqashelwa njengenye yezinto ezithembeke kakhulu zezakhiwo zomshini we-metrology kanye nokunemba okuphezulu. Uma iqhathaniswa nensimbi ephonswe noma insimbi, i-granite yezinga eliphezulu inikeza ukuzinza okumangalisayo kobukhulu kanye nokunemba kwesikhathi eside, okwenza ibe yindawo efanele kakhulu yokubhekisela, izisekelo zomshini, izisekelo zomhlahlandlela oqondile, kanye nezingxenye ezibalulekile ezisetshenziswa emishinini yokulinganisa ehlanganisiwe, ama-interferometer e-laser, imishini yokugaya i-CNC, kanye nezinhlelo zokuhlola ze-semiconductor.

Umbuzo owodwa ovame ukuphakanyiswa abasebenzisi ukuthi kungani izingxenye ze-granite ezinembile zimbozwa ngengqimba encane yamafutha ngaphambi kokuthunyelwa, nokuthi kungani kunconywa ukugcotshwa ngamafutha uma imishini izohlala ingasetshenziswa isikhathi eside. Njengoba i-granite ingagqwali, kusobala ukuthi uwoyela awukona ukuvimbela ukugqwala. Esikhundleni salokho, ifilimu evikelayo isebenzela injongo ehlukile newusizo kakhulu: ukuvikela ukunemba kwendawo yokusebenza.

Izingxenye ze-granite zakhiwe ngendlela eqine kakhulu, futhi izindawo zazo kumele zihlale zingenalo uthuli, izinhlayiya ezihudulayo, nezinye izinto ezingcolisayo. Ngisho nenani elincane lemfucumfucu encane lingathinta ukunemba kokulinganisa, futhi ukusula izinhlayiya ezinjalo ngqo ebusweni kungabangela imihuzuko emincane. Nakuba i-granite imelana kakhulu nokuguquguquka futhi ayikhi ama-burrs njengensimbi, imihuzuko ejulile ebusweni obunembile ingathinta ukusebenza kahle futhi ingadinga ukugoqwa kabusha noma ukulungiswa.

Ngokusebenzisa ifilimu yamafutha alula—ngokuvamile i-transformer oil noma ingxube ka-1:1 kawoyela womshini kanye nedizili—indawo iba lula kakhulu ukuyihlanza. Uthuli nezinhlayiya ezincane zinamathela kumafutha kunokuba zinamathele etsheni ngokwalo, futhi zingasuswa ngokusula ifilimu. Lokhu kunciphisa ingozi yokuhudula izinhlayiya ezirhabaxa endaweni yokusebenza futhi kugcina ubuqotho besikhathi eside bendiza yokubhekisela. Emishinini egcinwe isikhathi eside, ifilimu yamafutha ibaluleke kakhulu ngoba ukuqongelela kothuli kuyanda ngokuhamba kwesikhathi. Ngaphandle kwamafutha, ukuhlanza okomile kungashiya amamaki abonakalayo noma imihuzuko elimaza ukunemba kokulinganisa.

Ngesikhathi sokukhiqiza, izingxenye ze-granite ezinembile zivame ukudinga imishini eyengeziwe ukuze zihlanganiswe nezinye izinhlelo zemishini. Kuye ngemidwebo yamakhasimende, isakhiwo se-granite singafaka phakathi i-inserts enezintambo, i-T-slots, i-counterbores, noma imigodi edlulayo. I-insert ngayinye iboshelwe endaweni yayo ngemva kokucubungula i-granite ngokucophelela ngobukhulu obubekiwe, futhi ukubekezelelana kwesimo kumele kulawulwe ngokuqinile ukuqinisekisa ukuhlanganiswa okufanele nezingxenye zokuhlanganisa. Inqubo yokukhiqiza eqinile—ehlanganisa ukubhoboza, ukubopha ama-bushing ensimbi, kanye nokuqedwa kokugcina kwendawo—iqinisekisa ukuthi zonke izidingo ze-geometric ziyahlangatshezwa nokuthi ingxenye igcina ukunemba kwayo ngemva kokufakwa.

I-granite esezingeni eliphezulu inikeza izinzuzo eziningana ezibalulekile zokusetshenziswa kobunjiniyela bokunemba. Izinzile ngokwemvelo, ngokucindezeleka kwangaphakathi okukhishwa ukuguga isikhathi eside kwe-geological. Imelana nokugqwala, umswakama, kanye namakhemikhali amaningi. I-coefficient yayo yokwanda kokushisa okuphansi inciphisa izinguquko zokunemba ngenxa yokushintshashintsha kwezinga lokushisa. Futhi ngokungafani nezindawo zensimbi, imithelela emincane ku-granite ibangela imigodi emincane kune-burrs ephakanyisiwe, ngakho-ke i-reference plane ayiphambuki.

Ngenxa yalezi zizathu, i-granite iyaqhubeka nokudlala indima ebalulekile ku-metrology yesimanje, imishini ye-semiconductor, kanye nokukhiqizwa okunembile kakhulu. Ukuphathwa kahle—njengokufaka ifilimu kawoyela ngaphambi kokuthunyelwa noma ukugcina isikhathi eside—kusiza ukuqinisekisa ukuthi ingxenye ngayinye ye-granite enembile igcina ukusebenza kwayo kusukela efektri kuya kumsebenzisi wokugcina, isekela ukulinganisa okuthembekile kanye nokukhiqizwa okunembile kakhulu kuzo zonke izimboni.
