Historia

Early filing or rasping has prehistoric roots and grew naturally out of the blending of the twin inspirations of cutting with stone cutting tools (such as hand axes) and abrading using natural abrasives, such as well-suited types of stone (for example, sandstone).Relatedly, lapping is also quite ancient, with wood and beach sand offering a natural pair of lap and lapping compound. The Disston authors state, "To abrade, or file, ancient man used sand, grit, coral, bone, fish skin, and gritty woods,—also stone of varying hardness in connection with sand and water."

The Bronze Age and the Iron Age had various kinds of files and rasps. Archaeologists have discovered rasps made from bronze in Egypt, dating back to the years 1200–1000 BC. Archaeologists have also discovered rasps made of iron used by the Assyrians, dating back to the 7th Century BC.

Faili za kawaida zinaweza kugawanywa katika aina tano kulingana na sura ya sehemu nzima ya faili: faili za gorofa, faili za mraba, faili za triangular, faili za nusu-duara na faili za pande zote. Faili za gorofa hutumiwa kuweka nyuso za gorofa, za nje za mviringo na za laini; Faili ya mraba hutumiwa kufungua mashimo ya mraba, mashimo ya mstatili, na nyuso nyembamba; faili ya Pembetatu hutumiwa kuweka pembe za ndani, mashimo ya pembe tatu, na nyuso za gorofa; Faili za nusu pande zote hutumiwa kuweka nyuso zilizopindana na nyuso za gorofa;

Faili ya duara hutumiwa kufungua mashimo ya duara, nyuso ndogo zilizopinda na zenye umbo la duara. Faili maalum hutumiwa kufungua nyuso maalum za sehemu, na kuna aina mbili: moja kwa moja na iliyopigwa;

Faili ya kuunda ( faili za sindano) zinafaa kwa ajili ya ukarabati wa sehemu ndogo za kazi, na kuna seti nyingi za faili zilizo na maumbo mbalimbali ya sehemu ya msalaba.

Utangulizi wa faili za nusu-raundi

Faili za nusu pande zote

Faili ya nusu-raundi ni aina ya zana ya mkono inayotumika kutengua, kulainisha, na kuunda anuwai ya nyenzo kama vile chuma na kuni. Mchanganyiko wa upande tambarare na upande wa mviringo unamaanisha kuwa faili ya nusu duara ni bora kwa matumizi kwenye nyuso zenye michongo, mbonyeo na tambarare na kuifanya kuwa chombo chenye matumizi mengi.
