Pakuona vanamazvikokota vachikwesha nemaoko pakugadzira maturusi emuchina, munhu angabvunza kuti: “Unyanzvi uhwu hunogona kunyatso kusimudzira nzvimbo dzinogadzirwa nemichina here? Unyanzvi hwevanhu hunopfuura hwemichina here?”
Kana kutarisa kuri chete pane aesthetics, mhinduro ndeye "kwete." Kuchera hakugadziri kukwezva kwekuona, asi kune zvikonzero zvinomanikidza zvekushandisa kwayo kuenderera. Chimwe chinhu chakakosha chinhu chemunhu: nepo maturusi emuchina akagadzirirwa kugadzira mamwe maturusi, haagone kuburitsa chigadzirwa chinodarika chaiyo yepakutanga. Kuti tiwane muchina wakanyatsojeka kupfuura wakautangira, tinofanira kugadza nheyo itsva, iyo inoda kupindira kwevanhu-kunyanya, kukwenya kwemaoko.
Kukwenya hakusi kurongeka kana kusarongeka; asi, inzira yekudzokorodza chaiyo inonyatso tarisisa iyo yepakutanga workpiece, iyo inoshanda seyakajairwa referensi ndege, zvakare yakagadzirwa nemaoko.
Pasinei nechimiro chayo chinoda, kukwenya itsika ine hunyanzvi (yakafanana nechimiro chehunyanzvi). Kudzidzira shasha yekugera kunogona kunetsa pane kudzidzisa muvezi wemapuranga. Zvishandiso zvinokurukura nezvenyaya iyi zvishoma, kunyanya maererano nechikonzero chekukwesha, izvo zvinogona kuita kuti ionekwe sechimiro chehunyanzvi.
Ndotangira papi
Kana mugadziri akasarudza kushandisa grinder kubvisa zvinhu pachinzvimbo chekukwenya, njanji dze “master” grinder dzinofanirwa kuratidza kunyatsojeka kupfuura dzeguyo idzva.
Saka, chii chinotsigira kururama kwemuchina wekutanga?
Kunyatsoita uku kunogona kubva kumuchina wepamberi, zvinoenderana neimwe nzira inokwanisa kugadzira nzvimbo yakati sandara, kana kutorwa kubva kune iripo, yakanyatsogadzirwa yakafuratira nzvimbo.
Kuenzanisira maitiro ekugadzirwa kwepamusoro, tinogona kufunga nzira nhatu dzekudhirowa madenderedzwa (kunyangwe madenderedzwa ari mitsara yehunyanzvi, anoshandira kujekesa pfungwa). Mhizha ine hunyanzvi inogona kugadzira denderedzwa yakakwana ichishandisa kambasi yakajairwa. Sezvineiwo, kana akateedzera gomba rakatenderera patemplate yepurasitiki nepenzura, anodzokorora kusakwana kwese kwegomba iroro. Kana akaedza kudhirowa denderedzwa pachena, iko kurongeka kunozoganhurwa nehunyanzvi hwake.
Muchiono, nzvimbo yakati sandara yakakwana inogona kuwanikwa nekupenengura nzvimbo nhatu. Somuenzaniso, funga nezvematombo matatu, rimwe nerimwe riine nzvimbo yakati sandara. Nekukwesha nzvimbo idzi pamwe chete munhevedzano isina kurongeka, unozodzipfavisa zvishoma nezvishoma. Zvakadaro, kushandisa matombo maviri chete kunozokonzera concave uye convex mating pair. Mukuita, kupeta kunosanganisira kutevedzana kwakati, uko kunowanzo shandirwa nenyanzvi yekupeta kugadzira jig inodiwa, senge yakatwasuka kana ndiro yakati sandara.
Panguva yekugadzira, nyanzvi inotanga kushandisa mugadziri wemavara kune yakajairwa jig uye yobva yatsveta pamusoro penzvimbo yebasa kuti ione nzvimbo dzinoda kukweshwa.
