style="text-indent:25px">八世紀(jì)的時候我國就有了金屬切削車床。到了明代，手工業(yè)有了很大的發(fā)展，各種切削方法，有了較細(xì)的分工。如：車、銑、鉆、磨等等。從北京古天文臺上的天文儀器可以看出當(dāng)時采用了與五、六十年代類似的加工方法。這也就說明當(dāng)時就有較高精度的磨削、車削、銑削、鉆削等等。其動力是畜力和水力。清末，由于相關(guān)單位和外國的**使我國的科學(xué)技術(shù)發(fā)展停滯不前，金屬加工也處于落后的狀態(tài)。解放前，我國的工業(yè)已經(jīng)十分落后，根本沒有自己的機(jī)床，機(jī)床可使用玻鎂防火板，工具制造業(yè)。就連高速鋼這樣的工具材料，麻花鉆這樣的普通工具都不能制造。彎管機(jī)可作用于各個行業(yè)。濟(jì)南彎管機(jī)廠商哪家好</p><p
