                                                    提高機床精度的方法
                                                    作者:    發布于:2014-12-19 15:03:14    文字:【】【】【

                                                        修復機床導軌精度,數控導軌大都是利用鑄鐵或者不銹鋼所制造,在長時間的運行之下,加工部件和導軌之間往往會出現不均衡的摩擦程度,這樣一來就會加大熱量的急劇累加,不但加大了部件之間的表面摩擦還會加劇多于熱量的產生。安陽機床提出:如果不及時修復導軌,勢必會對機械加工帶來一定的誤差。通常情況下,我們對導軌所出現的輕微損傷,技術人員可以結合實際,利用一些先進的金屬修復材料對導軌進行維護和修復,這樣不會影響加工的進程,而對于一些受損比較嚴重的導軌,則要利用人工刮研的方式進行表面維護和修復。

                                                        調整主軸精度,機床在運行過程中,刀具和加工工件都是通過主軸進行固定,因此主軸精度的高低直接影響加工部件質量的高低。機床在大周期的運行環境下,回轉精度和主軸的穩定性因為受到摩擦和機械的振動受到不同程度的影響,因此在實際工作中一定要定期對其進行精度的修復和維護。如果出現精度相差比較大的情況,就需要對主軸進行拆卸修復,拆卸之后要進行詳細的檢查,然后根據檢查結果作出相應的修理計劃和方案。不過在實際工作中,很多單位都是對主軸軸承進行簡單的更換,有的也只是重新設定一下軸承的間隙以及相應的螺絲進行緊固處理。
