（1）生產效率高：用傳統(tǒng)的方法生產一根內徑420毫米，12米長的缸筒需154小時，用冷拔方法生產只需4分鐘。 </p> <p> （2）成品率高：由于鏜孔的滾壓頭兼起導向作用，在切削過程中，毛坯管由于自重產生撓度，致使?jié)L壓頭和鏜刀走偏，造成廢品。成品率只能達到60%左右，而用冷拔方法生產，成品率可達95%以上。 </p> <p> （3）金屬利用率高：用傳統(tǒng)的鏜孔方法制造缸體，金屬利用率只有50-70%。用拉拔方法生產時，金屬不但不被切削成鐵末，反而可以得到30%的延伸，金屬利用率可達95%。 </p> <p> （4）能改善成品管金屬的機械性能：用拉拔方法生產，使毛坯得到30%以上的塑性變形，由于加工硬化而使成品管金屬的強度限大為提高。一般在成品管內層強度限提高達60%。高精度冷拔管是用無縫熱軋鋼管、直縫焊管為坯料，經過化學處理后在**冷拔機上，通過特種變形原理設計的模具進行拉拔，生產出高精度管。其尺寸精度達H10～H8，直線度達0.35～0.5mm/m，表面粗糙度達Ra1.6-0.4。 </p><p> 冷拔扁鋼是常見的一種用于加工機械零件的鋼材。扁鋼的表面光潔度對機械零件的使用性能有很大的影響，有的用戶對于鋼材的光潔度有著較高的要求，那么怎樣才能提高鋼材的表面光潔度呢？常用的三種措施：<span style="font-size:12px;">一、要選用質量好的鋼料，如果鋼料質量不好，本身存在折疊，或者表面有夾雜、嚴重的刮傷和裂縫，在修磨處有棱角，冷拔扁鋼拔制后經延伸而容易出現折疊、裂縫等問題。</span><span style="font-size:12px;">二、在拔制前要清理管料上面的氧化鐵皮或其他質硬的污物，為了防止產生中由于氧化鐵皮或其他質硬的污物在拔制或矯直過程中壓入了鋼管表面，造成鋼管表面不平整。</span><span style="font-size:12px;">三、保持冷拔扁鋼生產場地、工具和潤滑劑等的清潔，防止氧化鐵皮和污物落到鋼管表面。</span>
