Momwe Mungayang'anire Kuwongoka kwa Granite Straightedge

Ma granite straightedges ndi zida zolondola zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga makina, metrology, ndi makina osonkhanitsira. Kuonetsetsa kuti granite straightedge ndi yolondola ndikofunikira kuti mutsimikizire kudalirika kwa muyeso ndi mtundu wa malonda. Pansipa pali njira zodziwika bwino zowunikira kulunjika ndi kulekerera kwa geometric kwa granite straightedges.

1. Kukhazikika kwa Mbali Yotsutsana ndi Malo Ogwirira Ntchito

Kuti muwone ngati mbali zowongoka zili molunjika:

• Ikani granite straightedge pa mbale yolinganizidwa bwino.

• Ikani choyezera chozungulira chokhala ndi 0.001mm kudzera mu bar yozungulira yokhazikika ndipo chiyikeni pa zero pogwiritsa ntchito sikweya yoyimira.

• Bweretsani choyezera chozungulira kuti chigwirizane ndi mbali imodzi ya m'mphepete wowongoka kuti mulembe kusiyana kwa perpendicularity.

• Bwerezani mbali inayo ndipo lembani cholakwika chachikulu ngati mtengo wokhazikika.

Izi zimatsimikizira kuti mbali zonse ziwiri zili ndi mawonekedwe ofanana ndi malo ogwirira ntchito, zomwe zimathandiza kuti muyeso usasinthe.

2. Chiŵerengero cha Malo Olumikizirana a Parallel Straightedge

Kuyesa kusalala kwa pamwamba potengera chiŵerengero cha kukhudzana:

• Ikani wosanjikiza woonda wa chowonetsera pamalo ogwirira ntchito a straightedge.

• Pakani pamwamba pang'onopang'ono pa mbale yathyathyathya yachitsulo chopangidwa ndi chitsulo chosungunuka kapena m'mphepete wina wowongoka wofanana kapena wapamwamba.

• Njirayi idzawulula malo olumikizirana omwe akuwoneka.

• Ikani gridi yowonekera bwino ya plexiglass (mabwalo ang'onoang'ono 200, iliyonse 2.5mm × 2.5mm) pamalo osasunthika pamwamba.

• Werengani chiwerengero cha masikweya okhala ndi malo olumikizirana (mu mayunitsi a 1/10).

• Chiŵerengero chapakati chimawerengedwa, chomwe chikuyimira malo ogwirira ntchito ogwira ntchito.

Njira iyi imapereka kuwunika kowoneka bwino komanso kochuluka kwa momwe pamwamba pa straightedge ilili.

3. Kuwongoka kwa Malo Ogwirira Ntchito

Kuyeza kulunjika:

• Thandizani straightedge pazizindikiro zokhazikika zomwe zili pa 2L/9 kuchokera kumapeto aliwonse pogwiritsa ntchito mabuloko ofanana kutalika.

• Sankhani mlatho woyenera woyesera malinga ndi kutalika kwa malo ogwirira ntchito (nthawi zambiri masitepe 8-10, okwana 50-500mm).

• Konzani autocollimator, electronic level, kapena precision spirit level ku mlatho.

• Sunthani mlatho pang'onopang'ono kuchokera kumapeto ena kupita kwina, mukulemba mawerengedwe pamalo aliwonse.

• Kusiyana pakati pa miyeso yayikulu ndi yocheperako kumasonyeza cholakwika cha kulunjika kwa malo ogwirira ntchito.

Pa miyeso yoposa 200mm, mbale yayifupi (50mm kapena 100mm) ingagwiritsidwe ntchito kudziwa cholakwika chowongoka ndi mawonekedwe apamwamba.

4. Kufanana kwa Malo Ogwirira Ntchito ndi Othandizira

Kufanana kuyenera kutsimikiziridwa pakati pa:

• Malo ogwirira ntchito apamwamba ndi otsika a straightedge.

• Malo ogwirira ntchito ndi malo othandizira.

Ngati palibe mbale yolumikizirana:

• Ikani mbali ya straightedge pa chothandizira chokhazikika.

• Gwiritsani ntchito micrometer yofanana ndi lever kapena micrometer yolondola yokhala ndi graduation ya 0.002mm kuti muyese kusiyana kwa kutalika kwa kutalika.

• Kupatuka kukuyimira cholakwika cha kufanana.

Mapeto

Kuwona kulondola kwa mizere yolunjika ya granite ndi geometric ndikofunikira kuti musunge umphumphu wa muyeso m'mafakitale olondola. Mwa kutsimikizira kukhazikika, chiŵerengero cha malo olumikizirana, kulunjika, ndi kufanana, ogwiritsa ntchito amatha kuwonetsetsa kuti mizere yawo yolunjika ya granite ikukwaniritsa miyezo yolondola kwambiri yofunikira pa ntchito zamafakitale ndi za labotale.
