	Ko TPI inobata sei gole saw kucheka? Iyo TPI yegomba saw inogona kukanganisa: 1. Inokurumidza sei kucheka
	2. Unhu hwekucheka kwakapedzwa, sekutsetseka kana kushata.
	3.Material iyo yakanakisisa yekucheka
Cheka kumhanya uye kunaka
	Huwandu hwemazino ane holesaw pa inch inosiyana kubva pamhando kuenda kune mhando, asi kazhinji iri pakati pe3 ne14 TPI.
	Semitemo yakawanda, mazino mashoma pa inch gomba saw ane, iyo inokurumidza kucheka kuburikidza neworkpiece. Zvakadaro, nekuti mazino acho akakura uye akaomarara, anogona kubvarura mafiibhi echinhu chauri kucheka uye anopedzisira aita rougher. Izvi zvingava zvakanaka kumabasa uko kurongeka kwegomba kusinganyanyi kukosha uye uko kusingazoonekwe mushure mekupedzwa.
	Iyo yakawanda mazino iyo saw ine, iyo inononoka inocheka kuburikidza neworkpiece. Zvisinei, nokuti mazino ari maduku uye akaonda, haakwanisi kubvarura kuburikidza nefibers yezvinhu uye naizvozvo kucheka kwekupedzisira kuchava nyore. Gomba rakatsvinda rinodiwa pamabasa apo buri racho richaonekwa uye kunyatsojeka kunodiwa, sekugadzira maburi echikiyi.

	Zvinokosha kucherechedza pano kuti haasi ose denderedzwa masaha ane denderedzwa nhamba mazino pa inch. Mamwe masaha anogona kunge aine nhanho 3 ½ painch, semuenzaniso.
	Izvo zvakakoshawo kucherechedza kuti mamwe anochinja-chinja gomba masaha anotsvedza uye achave nenhamba yakasiyana yemazino pa inch kana ichienzaniswa neichi inotevera padivi pesaha. Semuenzaniso, izvi zvinogona kuratidzwa se4/6 TPI. Izvi zvinoreva kuti ine mazino mana kusvika matanhatu painch.
Zvinhu
	Zvakaoma kutaura nechokwadi kuti imwe TPI yakakodzera kucheka chimwe chinhu, sezvo zvimwe zvinhu zvinokosha zvinofanira kuverengwa, zvakadai sezvinhu izvo mazino egomba rinogadzirwa. Kuti uwane rumwe ruzivo rwekuti ndeapi mahole saws anonyanya kucheka zvimwe zvinhu, ona peji ine musoro: Ndedzipi mhando dzemasaha egomba?
Gomba rakaona mazino
	Mazino emamwe masaha egomba anowanzo gadzirwa kubva kana kuputirwa nezvinhu zvekuvandudza mashandiro avo. Kazhinji kuvandudza kuoma, kupfeka kuramba uye kugona kucheka. Kuti uwane rumwe ruzivo ona peji ine musoro: Zvii zvokusarudza?
	Serrated/square mazino Siponji kana skweya mazino akasiyana zvishoma neakajairwa saha mazino, asi iwe uchiri kugona kuona TPI yavo (mazino painji) nekuyera inch kubva pakati pechidyiro chayo (kazhinji iyo yakaderera poindi) uye kuverenga kuti mangani mazino anowira mukati iyo inch. . Uyu mufananidzo unoratidza sikweya mazino gomba saw ine 3TPI.
