Kuwongolera kwa Hole Saw Teeth ndi TPI

TPI
	TPI imayimira "mano pa inchi" ndipo ndi njira yoyezera kuchuluka kwa mano pa tsamba la macheka. Nthawi zambiri amafupikitsidwa kukhala TPI, monga "tsamba lopangidwa ndi 18TPI".
	Kodi TPI imakhudza bwanji kudula kwa mabowo? TPI ya hole saw ingakhudze: 1. Ingadule bwanji?
	2. Ubwino wa odulidwa womalizidwa, monga wosalala kapena wovuta.
	3.Material omwe ndi abwino kwambiri kudula
Dulani liwiro ndi khalidwe
	Kuchuluka kwa mano obowola pa inchi kumasiyanasiyana kutengera mtundu, koma nthawi zambiri kumakhala pakati pa 3 ndi 14 TPI.
	Monga lamulo, mano ochepa pa inchi imodzi yomwe macheka amakhala nawo, m'pamenenso amadula kwambiri chogwirira ntchito. Komabe, chifukwa chakuti manowo ndi aakulu komanso okhwimitsa, amatha kung’amba ulusi wa zinthu zimene mukudulazo n’kufika pokhala okhwima kwambiri. Izi zitha kukhala zabwino pantchito zomwe kulondola kwa dzenje sikuli kofunikira komanso komwe sikudzawoneka mukamaliza.
	Mano ambiri omwe macheka ali nawo, pang'onopang'ono amadula ntchito. Komabe, chifukwa mano ndi ang'onoang'ono komanso ocheperako, sangadutse ulusi wa zinthuzo ndipo chifukwa chake kudula komaliza kumakhala kosalala. Bowo loyera limafunikira ntchito zomwe dzenjelo lidzawonekere komanso kulondola kumafunika, monga kupanga mabowo a maloko.
	Macheka otsika a TPI (mano 1-4 pa inchi) Masamba otsika a TPI amakhala ndi mano akulu omwe amakhala ndi zibowo zozama pakati pawo. Machekawa amadula mwachangu koma amakhala aukali kwambiri, ndikusiya malo okhwima pa workpiece.
	Mabowo okhala ndi TPI yapakatikati (mano 5-9 pa inchi) Macheka okhala ndi TPI yapakatikati amakhala okhazikika pakati pa macheka mwachangu, mwaukali komanso pang'onopang'ono, macheka osalala.
	Mitundu Yapamwamba ya TPI Hole Saw Blades (10+ TPI) Ma saw masamba okhala ndi mtengo wapamwamba wa TPI amakhala ndi mano ang'onoang'ono okhala ndi mipata yaying'ono pakati pawo. Machekawa amadula pang'onopang'ono koma amatulutsa odula kwambiri komanso osalala.
Mtengo wa TPI
	Kuti mupeze TPI ya tsamba la macheka, yambani kuyeza kuchokera pakati pa mmero (nthawi zambiri malo ake otsika kwambiri). Kaya ndi mano angati pa inchi kuchokera pamenepa, ndi mano angati pa inchi yomwe bowo lanu limakhala nalo.
	Ndikoyenera kudziwa kuti si macheka onse ozungulira omwe ali ndi mano ozungulira pa inchi. Macheka ena amatha kukhala ndi masitepe atatu ndi ½ pa inchi, mwachitsanzo.
	Ndikofunikiranso kudziwa kuti macheka ena osinthika amazungulira ndipo amakhala ndi manambala osiyanasiyana a mano pa inchi iliyonse poyerekeza ndi inchi yotsatira pa tsamba la macheka. Mwachitsanzo, izi zitha kufotokozedwa ngati 4/6 TPI. Izi zikutanthauza kuti ili ndi mano 4 mpaka 6 pa inchi.
Zida
	Zimakhala zovuta kunena motsimikiza kuti TPI inayake ndi yoyenera kudula chinthu china, popeza zinthu zina zofunika ziyenera kuganiziridwa, monga zinthu zomwe mano a dzenje amapangidwa. Kuti mudziwe zambiri za macheka omwe ali abwino kwambiri podula zida zina, onani tsamba lotchedwa: Kodi macheka mabowo ndi ati?
Bowo anaona mano
	Mano a macheka ena amabowo nthawi zambiri amapangidwa kuchokera kapena yokutidwa ndi zinthuzo kuti apititse patsogolo ntchito yawo. Kawirikawiri kukonza kuuma, kuvala kukana ndi kudula luso. Kuti mudziwe zambiri onani tsamba lotchedwa: Kodi ndi zinthu ziti zomwe mungasankhe?
	Mano osweka/makona Mano a siponji kapena masikweya amasiyana pang'ono ndi mano ocheka, koma mutha kudziwabe TPI (mano pa inchi) poyeza inchi kuchokera pakati pa bowo lake (nthawi zambiri malo otsika kwambiri) ndikuwerengera mano angati omwe amagwera mu inchi imeneyo. . Chithunzichi chikuwonetsa masikweya am'bowo okhala ndi 3TPI. Macheka a serrated kapena masikweya a mano ndi zobowola pakati amapangidwa kuti azidula zida zolimba monga konkriti, zomanga, matailosi a ceramic, galasi ndi miyala.
