Precision Granite Bridge Base ya Makina Oyezera Ogwirizana

Nyumba Yomangidwa Kuti Ikhale Yosasunthika

Makina onse oyezera zinthu amafanana ndi chimango chomwe chimayimapo. Ichi ndi gawo la makina lomwe palibe amene amalankhulapo pa ziwonetsero zamalonda - palibe ma servo motors, palibe masensa, palibe chomwe chimayatsa - komabe ndi gawo limodzi lomwe limatsimikiza ngati makina ena onse pa CMM angapereke kulondola komwe kwasindikizidwa pa pepala lake lofotokozera. Ndicho chifukwa chake maziko a mlathowu adamangidwira.

Yopangidwa kuchokera ku bolodi lolimba la granite wakuda wokhuthala, gawoli limapanga kapangidwe ka mlatho wa gantry komwe kumafanana ndi ma CMM a mkono wopingasa ndi mlatho: mizati iwiri yoyima yochokera ku mbale yayikulu yoyambira, yolumikizidwa ndi mtanda wopingasa pamwamba womwe umanyamula mzere wosuntha wa mlatho wa makinawo. Mizere yokhala ndi nthiti yomwe ikuyenda pa mtanda wapamwamba si yokongoletsera - ndi njira zowongolera zapansi zomwe makinawo amayendera, zomwe zikutanthauza kuti kuwongoka kwawo ndi kufanana kwawo kuyenera kukhala mkati mwa ma microns kutalika konse kwa mtandawo, osati pazitsanzo zochepa chabe.

Zimene Mukuyang'anadi

Poyang'ana gawolo lokha, mbale yoyambira imakhala ndi mabowo okhuthala okhala ndi ulusi omwe akuyenda pamwamba pake - mawonekedwe omwe amalola ophatikiza kuti atseke zida, zomangira zogwirira ntchito, kapena zowonjezera zina zoyezera kulikonse patebulo popanda kufunikira ntchito yobowola yapadera pa ntchito iliyonse. Mizati iwiri iliyonse ili ndi chibowo chachikulu chowunikira pakati, chomwe chimachepetsa kulemera popanda kusokoneza kulimba kwa mzati - tsatanetsatane womwe ndi wofunika kwambiri kuposa momwe umawonekera, popeza kilogalamu iliyonse yochotsedwa pa kapangidwe kosasunthika ndi kilogalamu imodzi yomwe makina owongolera kutentha safunika kukhazikika.

Kumapeto kwa pamwamba pake ndi kosalala, kosalala ngati kupukuta pankhope iliyonse — palibe mikwingwirima yopukutira, palibe zizindikiro zooneka za zida, palibe kusiyana kwa mitundu pakati pa magawo, zomwe nthawi zambiri zimakhala chizindikiro chowoneka bwino (ngakhale sichimalowa m'malo mwa satifiketi yeniyeni yowunikira) kuti chipikacho chinaphwanyidwa pa chopukutira chachikulu chimodzi chosamalidwa bwino m'malo mochisonkhanitsa kuchokera ku zinthu zosafanana. Choyikidwa pa mbale yoyambira pachithunzi chofotokozera chili ndi njanji yolunjika yokhala ndi mutu wofufuzira wokwezedwa — chomwe chawonetsedwa pano kuti chiwonetse momwe kapangidwe ka granite komalizidwa kamagwirizanirana ndi zinthu zoyenda ndi zomverera zomwe kasitomala angawonjezere akamakonza makina.

Chifukwa Chake Granite M'malo mwa Chitsulo Chofewa

Chimango cha mlatho chopangidwa ndi chitsulo chosungunulidwa kapena chopangidwa ndi chitsulo ndi chotsika mtengo kutsogolo komanso mwachangu kupanga, koma chimabwera ndi mavuto awiri omwe samawonekera mpaka makinawo atakhala akugwira ntchito kwa kanthawi: kupsinjika kwa mkati komwe kumachepa pang'onopang'ono kwa miyezi ingapo ndikupangitsa kuti chimangocho chisunthe pang'ono, ndipo kuchuluka kwa kutentha komwe kumawonjezeka kuwirikiza kawiri kuposa kwa granite wokhuthala. Pazigawo zoyezera za CMM ku tolerances za ma micron amodzi, vuto lililonse mwa izi ndilokwanira kupangitsa kuti kulondola kwa makinawo kusakhale kopanda tanthauzo mkati mwa chaka chimodzi kuchokera pamene adayikidwa. Granite ilibe kupsinjika kwamkati kuti ichepetse - idapangidwa kale ndi kupsinjika kwachilengedwe kwa geological - ndipo coefficient yake yotsika komanso yokhazikika ya kukulitsa kutentha imatanthauza kuti kapangidwe kake kamasunga mawonekedwe ake kudzera mu kusintha kwa kutentha kwatsiku ndi tsiku pa shopu, osati mkati mwa labu yolamulidwa ndi nyengo yokha.
