I-Granite Surface Plate Machining kunye neSikhokelo soLondolozo: Ipleyiti echanekileyo yomphezulu wegranite ifuna umatshini kunye nokugcinwa okukhethekileyo ukuqinisekisa ukuchaneka kwayo kunye nokuphila ixesha elide. Ngaphambi kokupholisha, icandelo legranite kufuneka liqhubele phambili kumatshini wokuqala kunye nohlengahlengiso oluthe tyaba olusekwe kwimigaqo yokubeka i-triangular. Emva kokusila okuthe tye, ukuba i-CNC machining ayikwazi ukufezekisa ukuchaneka okufunekayo-ngokuqhelekileyo ukufikelela kwiBanga le-0 ukuchaneka (0.01mm / m ukunyamezela njengoko kuchazwe kwi-DIN 876) -ukugqiba ngesandla kuba yimfuneko ukuze kuphunyezwe amabakala aphezulu achanekileyo afana neBanga le-00 (0.005mm / m ukunyamezela nge-ASTM7 yemigangatho ye-ASTM 89).3.
Inkqubo yomatshini ibandakanya amanyathelo abalulekileyo aliqela. Okokuqala, ukugawula ngokurhabaxa kuseka isiseko esisicaba, kulandele isiqingatha sesibini sokugqiba ukususa amanqaku omatshini. Ukusila ngokuchanekileyo, okuhlala kusenziwa ngesandla, kuphucula umgangatho ukuze kufezekiswe ukunyamezela okufunwayo kunye nobunzima bomhlaba (ixabiso le-Ra le-0.32-0.63μm, apho i-Ra imele i-arithmetic ithetha ukutenxa kwiprofayili yomphezulu). Ekugqibeleni, ukuhlolwa okucokisekileyo kuqinisekisa ukuthotyelwa kwemigangatho yobugcisa, kunye namanqaku okulinganisa abekwe ngokucwangcisiweyo kuwo wonke ama-diagonals, amaphethelo, kunye ne-midlines-ngokuqhelekileyo i-10-50 amaphuzu ngokuxhomekeke kubukhulu beplate-ukuqinisekisa ukuhlolwa kokuchaneka okufanayo.
Ukuphatha kunye nofakelo kuchaphazela kakhulu ukuchaneka. Ngenxa yobulukhuni be-granite (ubunzima be-Mohs 6-7), ukunyuswa okungafanelekanga kunokubangela ukuguqulwa okusisigxina. Kwizicelo ezibalulekileyo ezifuna ukuchaneka kweBanga le-00, i-post-installation hand lapping ibalulekile ukubuyisela ukuchaneka okuchanekile ngexesha lothutho. Le ngqalelo kwiinkcukacha yahlula iipleyiti zomphezulu zegranite ezichanekileyo kwiinguqulelo ezisemgangathweni zoomatshini.
Izenzo zokulondoloza zichaphazela ngokuthe ngqo ukusebenza kunye nobomi. Qala ngokucoca ngokucokisekileyo usebenzisa izicoci ze-pH ezingathathi hlangothi-zigweme izinto ezine-acidic ezinokuthi zifake umphezulu. Ukulinganisa ngonyaka kunye ne-laser interferometers, elandelwayo kwimigangatho ye-NIST, iqinisekisa ukuchaneka okuqhubekayo. Xa ubeka i-workpieces, vumela ukulingana kwe-thermal (ngokuqhelekileyo i-15-30 imizuzu) ukukhusela iimpazamo zokulinganisa ukusuka kwimilinganiselo yokushisa. Ungaze utyibilikise izinto ezirhabaxa kumhlaba wonke, njengoko oku kunokudala imikrwelo emincinci echaphazela ukucaba.
Izikhokelo zokusetyenziswa ngokufanelekileyo zibandakanya ukuhlonipha imida yomthwalo wokuthintela ukuguqulwa kwesakhiwo, ukugcina iimeko ezizinzileyo zokusingqongileyo (iqondo lobushushu 20±2 ° C, ukufuma 50±5%), kunye nokusetyenziswa kwezixhobo zokuphakamisa ezizinikeleyo ukuphepha umonakalo wenqwelomoya. Ngokungafaniyo noogxa besinyithi, ukuzinza kwe-thermal ye-granite (0.01ppm/°C) kunciphisa iimpembelelo zokusingqongileyo, kodwa utshintsho lwesiquphe lobushushu kusafuneka luphetshwe.
Njengesixhobo esisisiseko kwi-metrology echanekileyo, iipleyiti zomphezulu zegranite eziqinisekisiweyo (i-ISO 17025 evunyiweyo) zisebenza njengomgangatho wereferensi kwimilinganiselo yobukhulu. Ukugcinwa kwazo kufuna umgudu omncinane—ukucoca ngelaphu elingena-lint emva kokuba ulisebenzisile—akufuneki zityatyambo zikhethekileyo okanye izithambiso. Ngokulandela ezi prothokholi zoomatshini kunye nokhathalelo, iipleyiti zomphezulu zegranite ezichanekileyo zinikezela ukusebenza okuthembekileyo kumashumi eminyaka, zizenza zibe yimfuneko kwiilebhu zokulinganisa, ukwenziwa kwe-aerospace, kunye nezicelo zobunjineli ezichanekileyo.
