Momwe Mungawonere Kuwongoka kwa Granite Straightedge

Ma granite straightedges ndi zida zolondola zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga makina, metrology, ndi kusonkhana kwamakina. Kuwonetsetsa kulondola kwa granite kuwongoka ndikofunikira kuti mutsimikizire kudalirika kwa kuyeza komanso mtundu wazinthu. M'munsimu muli njira zowunikira zowongoka ndi kulolerana kofananira kwa ma granite owongoka.

1. Perpendicularity ya Mbali Yotsutsana ndi Ntchito Yogwira Ntchito

Kuwona perpendicularity ya mbali zowongoka:

• Ikani chowongoka cha granite pa mbale yokhazikika.

• Ikani dial gauge yokhala ndi omaliza maphunziro a 0.001mm kudzera pa bar yozungulira yokhazikika ndi zero pogwiritsa ntchito sikwele.

• Bweretsani dial gauge kuti igwirizane ndi mbali imodzi ya straightedge kuti mulembe kupotoza kwa perpendicularity.

• Bwerezani kumbali ina ndikulemba zolakwika zazikulu monga mtengo wa perpendicularity.

Izi zimawonetsetsa kuti nkhope zam'mbali zimakhala zozungulira pamalo ogwirira ntchito, zomwe zimalepheretsa kuti miyeso ikhale yosiyana panthawi yogwiritsira ntchito.

2. Contact Point Area Ratio of a Parallel Straightedge

Kuyesa kusalala kwa pamwamba polumikizana ndi chiŵerengero:

• Ikani gawo lochepa la wothandizila wowonetsera kumalo ogwirira ntchito a straightedge.

• Pakani pamwamba pang'onopang'ono pa mbale yachitsulo yopangidwa ndi chitsulo kapena mizere ina yowongoka yofanana kapena yolondola kwambiri.

• Njirayi idzawulula malo olumikizirana owoneka.

• Ikani gululi wowonekera (mabwalo ang'onoang'ono 200, 2.5mm × 2.5mm iliyonse) pamalo owoneka bwino pamtunda.

• Werengani kuchuluka kwa mabwalo omwe ali ndi malo olumikizirana (mu mayunitsi a 1/10).

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

Njirayi imapereka kuwunika kowoneka ndi kuchuluka kwa mawonekedwe amtundu wa straightedge.

3. Kuwongoka kwa Malo Ogwira Ntchito

Kuyeza kuwongoka:

• Thandizani zowongoka pazikhomo zomwe zili pa 2L/9 kuchokera kumapeto kulikonse pogwiritsa ntchito midadada yofanana kutalika.

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

• Tetezani chotengera cha autocollimator, mulingo wamagetsi, kapena mulingo wolondola wa mzimu mpaka pamlatho.

• Sunthani mlathowo pang'onopang'ono kuchokera kumapeto mpaka kumapeto, ndikulemba zowerengera pamalo aliwonse.

• Kusiyanitsa pakati pa chiwerengero chachikulu ndi chochepa chimasonyeza cholakwika chowongoka cha malo ogwirira ntchito.

Pamiyezo yakumaloko yopitilira 200mm, mbale yayifupi ya mlatho (50mm kapena 100mm) ingagwiritsidwe ntchito kudziwa cholakwika chowongoka chokhala ndi malingaliro apamwamba.

4. Parallelism of Working and Support Surfaces

Kufanana kuyenera kutsimikiziridwa pakati pa:

• Pamwamba ndi m'munsi ntchito malo a straightedge.

• Malo ogwirira ntchito ndi malo othandizira.

Ngati mbale yaflat yofotokozera palibe:

• Ikani mbali yowongoka pa chothandizira chokhazikika.

• Gwiritsani ntchito micrometer yamtundu wa lever kapena mikrometer yolondola yokhala ndi omaliza maphunziro a 0.002mm kuti muyeze kutalika kwa kutalika kwake.

• Kupatuka kumayimira cholakwika cha parallelism.

Mapeto

Kuwona kuwongoka ndi kulondola kwa geometric kwa ma granite owongoka ndikofunikira kuti musunge kukhulupirika kwa muyeso m'mafakitale olondola. Potsimikizira perpendicularity, chiŵerengero cha malo olumikizana, kuwongoka, ndi kufanana, ogwiritsa ntchito amatha kuonetsetsa kuti mawongoledwe awo a granite akukwaniritsa miyezo yolondola kwambiri yofunikira pakugwiritsa ntchito mafakitale ndi labotale.
