Cov ntaub ntawv steel los yog steel rasp

Keeb kwm

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.

Cov ntaub ntawv zoo ib yam tuaj yeem muab faib ua tsib hom raws li cov duab ntawm cov ntaub ntawv hla ntu: cov ntaub ntawv tiaj tus, cov ntaub ntawv square, cov ntaub ntawv triangular, cov ntaub ntawv ib nrab voj voog, thiab cov ntaub ntawv puag ncig. Cov ntaub ntawv tiaj tus yog siv los ua cov ntaub ntawv tiaj tus, lub voj voog sab nraud, thiab qhov chaw convex; Cov ntaub ntawv square yog siv los sau cov square qhov, lub qhov sib npaug, thiab qhov chaw nqaim; Daim duab peb sab yog siv los ua cov ntaub ntawv sab hauv, daim duab peb sab qhov, thiab tiaj tus; Cov ntaub ntawv ib nrab puag ncig yog siv los ua cov ntaub ntawv concave nkhaus thiab tiaj tus;

Cov ntaub ntawv puag ncig yog siv los ua cov kab puag ncig, me me concave curved nto, thiab elliptical nto. Cov ntaub ntawv tshwj xeeb yog siv los ua cov ntaub ntawv tshwj xeeb ntawm qhov chaw, thiab muaj ob hom: ncaj thiab nkhaus;

Shaping cov ntaub ntawv (cov ntaub ntawv koob) yog tsim rau kho me me ntawm workpieces, thiab muaj ntau pawg ntawm cov ntaub ntawv nrog ntau yam cross-sectional duab.
