它可以提高低碳鋼的切削性能，切削易分離。但工作的精密無縫鋼管進(jìn)一步加工困難的硬化。如冷拔鋼絲，由于加工硬化進(jìn)一步能耗高的畫，甚至被破壞，因而必須通過中間退火加工硬化，然后繪制。當(dāng)切削硬脆工件的表面層，和增加切割速度的切削力，刀具磨損等。冷軋精密無縫鋼管具有內(nèi)外壁無氧化層、承受高壓無泄漏、高精度、高光潔度、冷彎不變形、擴(kuò)口壓扁無裂縫、表面已作防銹處理等特點(diǎn)，主要用于機(jī)械結(jié)構(gòu)、液壓設(shè)備及汽車摩托車的氣動(dòng)或液壓元件，如氣缸或油缸等。冷軋基本的工藝流程是：熱軋毛管—>毛管檢查、修磨—>毛管酸洗—>毛管酸洗后復(fù)檢—>冷軋—>精拉道次前矯直—>酸洗、潤(rùn)滑—>精拉—>成品前處理—>入庫(kù)。生產(chǎn)需要注意控制：毛管壁厚要均勻、內(nèi)外表面缺陷少；要配置外表面拋光及內(nèi)孔缺陷清理設(shè)備。與普通冷軋鋼管相比，冷軋精密無縫鋼管生產(chǎn)增加了熱軋毛管酸洗復(fù)檢工序，主要是要保證毛管外表面無折疊、裂紋等缺陷，排除掉內(nèi)表面存在折疊、嚴(yán)重劃線、麻面等缺陷的毛管。一般冷軋精密無縫鋼管生產(chǎn)所使用的工具的表面光潔度要求在Ra0.4以上，尺寸精度達(dá)到H3以上，硬度要求在HRC70以上。同時(shí)要求拉軋過程中不能出現(xiàn)頂頭或模具粘鋼現(xiàn)象。
