Ndi mapini amtundu wanji omwe alipo?

Zikhomo zokankhira zimapezeka muutali wosiyanasiyana, zolemera ndi ma diameter ndipo zimaphatikizapo izi:
Pusher kutalika
	Kutalika kwa kasupe wa mpesa ndi pafupifupi 178 mm ( mainchesi 7).
	Kusiyana kwa kutalika kwa zikhomo zokankhira ndi chifukwa chakuti zikhomo zamakono zilibe nsonga, ndipo zina zilibenso silinda. Chifukwa chake, pini yokankhira yamakono nthawi zambiri imakhala pafupifupi 152 mm ( mainchesi 6) kutalika. kutalika.
	Kusiyanitsa kwa kutalika kwa kachipini makamaka chifukwa cha kutalika kwa mapini omwe amagwiritsidwa ntchito. Mwachitsanzo, mutha kugwiritsa ntchito chokokera misomali kuyambira 165 mm (6 1/2 mainchesi) mpaka 203 mm (8 mainchesi). zazitali, zokhala ndi mapini kuyambira 15.87 mm (5/8 in.) mpaka 38 mm (1 1/2 in.) yaitali.
	Muyenera kugwiritsa ntchito V-misomali ya 152 mm (6 inchi) yokhala ndi V-misomali 7 mm (0.27 inch) kapena 10 mm (0.39 inchi).
	Muyenera kugwiritsa ntchito pini ya 152 mm (6 inchi) yokhala ndi mapini 7 mm (0.27 inch), 10 mm (0.39 inch) ndi 12 mm (0.47 inch).
Pin kulemera
	Mabatani okhala ndi chogwirira chamatabwa nthawi zambiri amalemera pafupifupi 100 g (3.52 oz). Mabatani a matabwa amakhala olimba koma osalemera.
	Mabatani okhala ndi chogwirira cha pulasitiki nthawi zambiri amalemera pafupifupi 50g (1.76oz). Batani lokhala ndi chogwirira cha pulasitiki ndi losavuta kugwira. Komabe, zingawoneke ngati zopepuka kwambiri kuti zigwiritsidwe ntchito molimba mtima.
Pin diameter
	Makankhira amatha kukhala 2 mm (0.07 in.), 3 mm (0.11 mkati) kapena 4 mm (0.15 mu.) m'mimba mwake. mpaka kukula kwa mainchesi a mutu wa pini iyi. Kuti mupindule kwambiri ndi pini yokankhira, onetsetsani kuti mainchesi a mutu wa piniwo ndi wocheperako kapena wofanana ndi kukula kwa piniyo. Zitsanzo za mapini ogwiritsiridwa ntchito ndi mapini akukankha akuwonetsedwa pansipa.
	Ndi pin yanji yomwe ndiyenera kugwiritsa ntchito ndi pini yokankha? Mapini a maboti achitsanzo, mapini a veneer ndi mapini opyapyala a njanji atha kugwiritsidwa ntchito ndi pini yokakamiza ya 2 mm (0.77 inch). Pini yolemera kwambiri ya 3 mm (0.11 in.) ifunika 3 mm (0.11 in.) pini yokankhira.
	Kuthamanga kwa pini yapakati ndi 4 mm (0.15 mu.); mapini okhala ndi mutu wa 3 mm (0.11 inchi) mpaka 4 mm (0.15 inchi) ndi oyenera kugwiritsidwa ntchito ndi pushpin iyi.
	Kampaniyo Choponyera mapini chimakhala ndi mapini okhala ndi mainchesi 1.5 mm (0.05 mkati) kuti azigwira ntchito ndi zitsanzo zomwe zimagwiritsa ntchito zikhomo zazing'ono, zopapatiza.
