Kwishishini lokulungisa iindawo ezichanekileyo, ukuchaneka okwaneleyo kudla ngokuba yimbonakaliso ecacileyo yamandla ayo okusebenza kwiworkshop. Siyazi ukuba ubushushu yeyona nto iphambili echaphazela ukuchaneka komatshini.
Kwinkqubo yokucubungula engokwemvelo, phantsi kwesenzo semithombo eyahlukeneyo yobushushu (ubushushu bengxabano, ubushushu bokusika, ubushushu be-ambient, i-thermal radiation, njl.), xa ubushushu besixhobo somatshini, isixhobo kunye nesixhobo sokusebenzela sitshintsha, ukuguqulwa kwe-thermal kuya kwenzeka. Kuya kuchaphazela ukufuduka okuhlobene phakathi kwendawo yokusebenza kunye nesixhobo, yenze ukutenxa ngomatshini, kwaye emva koko kuchaphazele ukuchaneka komatshini wenxalenye. Ngokomzekelo, xa i-coefficient yokwandisa i-linear yensimbi yi-0.000012, ukunyuswa kweengxenye zetsimbi ezinobude be-100 mm kuya kuba ngu-1.2 um kwi-1℃ yokwanda kweqondo lokushisa. Ukutshintsha kweqondo lokushisa akuchaphazeli ngokuthe ngqo ukwandiswa kwendawo yokusebenza, kodwa kuchaphazela ukuchaneka kwesixhobo somatshini.
Kwi-machining echanekileyo, iimfuno eziphezulu zibekwe phambili ukuchaneka kunye nokuzinza kwe-workpiece. Ngokwezibalo zezixhobo ezifanelekileyo, ukuphambuka komatshini okubangelwa yi-akhawunti ye-thermal deformation kwi-40% - 70% ye-total machining deviation of precision machining. Ngoko ke, ukwenzela ukuthintela ukwandiswa kunye nokucutshungulwa komsebenzi obangelwa ukuguquka kweqondo lokushisa, ukushisa kwereferensi yendawo yokwakha ngokuqhelekileyo kulawulwa ngokungqongqo. Zoba umda wokutenxa wenguqu yobushushu, i-200.1 kunye ne-200.0 ngokulandelanayo. Unyango lwe-thermostatic lusaqhutywa kwi-1℃.
Ukongeza, itekhnoloji yokulawula ubushushu obuchanekileyo inokusetyenziselwa ukulawula ngokuchanekileyo ukuguqulwa kwe-thermal yamalungu ukuphucula ukuchaneka komatshini wokuchaneka. Umzekelo, ukuba utshintsho lweqondo lobushushu kwireferensi yesixhobo sokusila silawulwa ngaphakathi kwe-± 0.5 ℃, ukuhanjiswa kwe-gapless kunokufezekiswa kwaye impazamo yothumelo inokupheliswa; Xa ubushushu be-screw rod bulungiswa ngokuchaneka kwe-0.1 ℃, impazamo ye-pitch ye-screw rod inokulawulwa ngokuchaneka kwe-micrometer. Ngokucacileyo, ulawulo oluchanekileyo lweqondo lokushisa lunokunceda ukufezekisa ukuchaneka okuphezulu okungenakufezekiswa ngoomatshini, umbane, i-hydraulic kunye nezinye iitekhnoloji zodwa.
4 Uyilo olutsha lobuchwephesha kunye nokuvelisa ukuhluza okupholisa i-oyile kunye nezixhobo zokulawula ubushushu, ukwahlula amanzi e-oyile kunye nokuqokelelwa kwenkungu ye-oyile, ukuhluzwa kothuli, ukucolwa komphunga kunye nokubuyiswa, ubushushu obuchanekileyo berhasi yolwelo, ukucocwa kolwelo kunye nokuvuselelwa ngokutsha, itshiphu kunye ne-slag de-liquid recovery and ezinye izixhobo ezipholileyo zokulawula izixhobo ezahlukeneyo zomatshini kunye nemigca yokuvelisa, kwaye ibonelela ngezinto ezixhasayo zokucoca kunye neenkonzo zobugcisa zolawulo olupholileyo, ukubonelela abathengi ngezisombululo ezahlukeneyo zengxaki yolawulo olupholileyo.
