Amafayela ensimbi noma i-rasp yensimbi

steel rasp Ukwahlukaniswa

Amafayela ensimbi angahlukaniswa cishe abe izigaba ezintathu: amafayela ajwayelekile, amafayela akhethekile, ukubumba amafayela enaliti amafayela;

Amafayela ensimbi noma i-rasp yensimbi

Umlando

Ukufaka kwangaphambi kwesikhathi noma ukudlwengula kunezimpande zangaphambi komlando futhi kwakhula ngokwemvelo ekuhlanganisweni kokugqugquzelwa okungamawele kokusika ngamathuluzi okusika amatshe (njengama-axi esandla) nokuhuqa kusetshenziswa ama-abrasives emvelo, njengezinhlobo zamatshe ezifaneleke kahle (isibonelo, i-sandstone) .Okuhlobene, i-lapping nayo iyinto yakudala, izinkuni nesihlabathi sasogwini zinikeza ipheya yemvelo ye-lap ne-lapping compound. Ababhali be-Disston bathi, "Ukuze abrade, noma ifayela, indoda yasendulo yasebenzisa isihlabathi, i-grit, i-coral, ithambo, isikhumba senhlanzi, ne-gritty woods, -futhi itshe lobunzima obuhlukahlukene mayelana nesihlabathi namanzi."

I-Bronze Age kanye ne-Iron Age yayinezinhlobo ezahlukene zamafayela nama-rasp. Abavubukuli bathole ama-rasps enziwe ngethusi e-Egypt, asukela eminyakeni engu-1200-1000 BC. Abavubukuli baphinde bathola ama-rasps enziwe ngensimbi asetshenziswa ama-Asiriya, aqala ngekhulu lesi-7 BC.

Amafayela avamile angahlukaniswa abe izinhlobo ezinhlanu ngokusekelwe ekumeni kwesigaba sesiphambano sefayela: amafayela ayisicaba, amafayela ayisikwele, amafayela angunxantathu, amafayela ayindilinga, namafayela ayindilinga. Amafayela ayisicaba asetshenziselwa ukufaka indawo eyisicaba, eyindilinga yangaphandle, kanye ne-convex; Ifayela eliyisikwele lisetshenziselwa ukufaka izimbobo eziyisikwele, izimbobo eziwunxande, nezindawo eziwumngcingo; ifayela elingunxantathu lisetshenziselwa ukufaka amakhona angaphakathi, imigodi engunxantathu, nezindawo eziyisicaba; Amafayela ayindilinga ayisigamu asetshenziselwa ukufaka izindawo ezigobile ezigobile kanye nezindawo eziyisicaba;

Ifayela eliyindilinga lisetshenziselwa ukufaka izimbobo eziyindilinga, izindawo ezincane ezigobile ezigobile, nezindawo eziyiziyingi. Amafayela akhethekile asetshenziselwa ukufaka izindawo ezikhethekile zezingxenye, futhi kunezinhlobo ezimbili: eziqondile nezigobile;

Ifayela lokubumba (amafayela enaliti) afaneleka ukulungisa izingxenye ezincane zezinto zokusebenza, futhi kunamasethi amaningi wamafayela anomumo ohlukahlukene we-cross-sectional.

Isingeniso samafayela ayindilinga

Amafayela ayindilinga

Sinikezela ngokomsebenzi zonke izinhlobo zamafayela ensimbi & ama-rasps namafayela edayimane namafayela enaliti.amafayela ensimbi ekhabhoni ephezulu,4"-18" ukusika okuphindwe kabili (ukusika: i-bastard, okwesibili, okubushelelezi).

Ifayela eliyindingilizi iwuhlobo lwethuluzi lesandla elisetshenziselwa ukususa, ukushelela, nokubumba uhla lwezinto ezifana nensimbi nokhuni. Inhlanganisela yohlangothi oluyisicaba kanye nohlangothi oluyindilinga kusho ukuthi ifayela eliyindilinga eliyisigamu lilungele ukusetshenziswa endaweni eyi-concave, convex, neyisicaba okwenza libe yithuluzi eliguquguqukayo kakhulu.
