I-Granite Surface Plate Machining and Maintenance Guide: Ipuleti langaphezulu legwadle elinembayo lidinga ukwenziwa kwemishini okukhethekile nokunakekelwa ukuze kuqinisekiswe ukunemba kwalo nokuphila isikhathi eside. Ngaphambi kokupholisha, ingxenye yegwadle kufanele icutshungulwe umshini wokuqala kanye nokulungiswa okuvundlile okusekelwe kumigomo yokuma engunxantathu. Ngemva kokugaya okuvundlile, uma ukwenza imishini ye-CNC ingakwazi ukufinyelela ukunemba okudingekayo—okuvame ukufinyelela ukunemba kweBanga 0 (ukubekezelela okungu-0.01mm/m njengoba kucaciswe ku-DIN 876)—ukuqedela ngesandla kuba kudingekile ukuze kuzuzwe amamaki anemba aphakeme njengeBanga 00 (ukubekezelela okungu-0.005mm/m nge-ASTM7 89).3.
Inqubo yokwenza imishini ihilela izinyathelo ezimbalwa ezibalulekile. Okokuqala, ukugaya okumahhadlahhadla kusungula ukucaba okuyisisekelo, okulandelwa ukuqeda kancane ukuze kukhishwe amamaki omshini. Ukugaya okunembayo, okuvamise ukwenziwa ngesandla, kucwengisa indawo engaphezulu ukuze kufinyelele ukubekezelelana kokucaba okufiselekayo kanye nokuqina kwendawo (inani lika-Ra elingu-0.32-0.63μm, lapho u-Ra emelela ukuchezuka kwesilinganiso se-arithmetic sephrofayela engaphezulu). Okokugcina, ukuhlola ngokucophelela kuqinisekisa ukuhambisana nezindinganiso zobuchwepheshe, ngamaphuzu okulinganisa abekwe ngokuhlelekile kuwo wonke ama-diagonal, imiphetho, nemigqa ephakathi—imvamisa amaphuzu ayi-10-50 kuye ngosayizi wepuleti—ukuqinisekisa ukuhlolwa kokunemba okufanayo.
Ukuphatha kanye nokufakwa kunomthelela kakhulu ukunemba. Ngenxa yokuqina kwegwadle (ukuqina kwe-Mohs 6-7), ukuphakamisa okungafanele kungabangela ukuwohloka unomphela. Kuzinhlelo zokusebenza ezibucayi ezidinga ukunemba kweBanga 00, ukuxhashazwa kwesandla kwangemva kokufakwa kubalulekile ukuze kubuyiselwe ukunemba okonakele ngesikhathi sokuthutha. Lokhu kunakekela emininingwaneni kuhlukanisa amapuleti angaphezulu okunemba kwegranite kusukela ezinguqulweni ezijwayelekile zomshini.
Izinqubo zokunakekela zithinta ngokuqondile ukusebenza neminyaka yokuphila. Qala ngokuhlanza ngokuphelele usebenzisa izihlanzi ze-pH ezingathathi hlangothi-gwema izinto ezine-acidic ezingabamba phezulu. Ukulinganisa kwaminyaka yonke ngama-laser interferometer, alandeleka kumazinga we-NIST, kuqinisekisa ukunemba okuqhubekayo. Lapho ubeka ama-workpieces, vumela ukulingana okushisayo (imvamisa imizuzu eyi-15-30) ukuvikela amaphutha okulinganisa kusukela ekuhlukeni kwezinga lokushisa. Ungalokothi uslayide izinto ezimahhadlahhadla uwele phezulu, njengoba lokhu kungadala imihuzuko emincane ethinta ukucaba.
Imihlahlandlela yokusetshenziswa efanele ihlanganisa ukuhlonipha imingcele yomthwalo ukuze kuvinjelwe ukuwohloka kwesakhiwo, ukugcina izimo zemvelo ezizinzile (izinga lokushisa elingu-20±2°C, umswakama ongu-50±5%), kanye nokusebenzisa izinto zokuphakamisa ezizinikele ukuze kugwenywe ukulimala kwendiza. Ngokungafani nozakwabo be-metallic, ukuzinza kwe-thermal ye-granite (0.01ppm/°C) kunciphisa imithelela yemvelo, kodwa ukuguquka kwezinga lokushisa okungazelelwe kusafanele kugwenywe.
Njengethuluzi eliyisisekelo ku-precision metrology, amapuleti angaphezulu kwegwadle aqinisekisiwe (i-ISO 17025 egunyaziwe) asebenza njengezinga lenkomba lezilinganiso zobukhulu. Ukugcinwa kwazo kudinga umzamo omncane—ukumane uzisule ngendwangu engenantambo ngemva kokusetshenziswa—akudingeki izinto zokuthambisa ezikhethekile noma izinto zokuthambisa. Ngokulandela lezi zinqubo zokwenza imishini nokunakekelwa, amapuleti angaphezulu kwegwadle alethe ukusebenza okuthembekile amashumi eminyaka, okuwenza abaluleke kakhulu kumalabhorethri okulinganisa, ukukhiqizwa kwe-aerospace, kanye nezinhlelo zokusebenza zobunjiniyela ezinemba okuphezulu.
