对于激光切割机来说,使用时间久了,需要经常更换一些配件来保证激光切割机的性能稳定,这些配件称之为易损件,其中喷嘴和镜片是激光切割机更换得最为频繁的配件。

 

其中聚焦镜片是一种比较精密的光学元件,其洁净程度直接影响激光切割机的加工性能和质量。所以,定时对聚焦镜片的保养是非常必要的。今天小编就为大家带来了聚焦镜片的保养流程和注意要点,一起往下看吧~

 

 

保养激光切割机聚焦镜片的正确操作流程:

 

1.镜架中取出聚焦镜:松开紧固螺丝,依次取下气嘴和镜筒;先用吹气球吹去镜片表面的灰尘;

 

2.如确实需要清洁镜片,只能采用实验室级别的纸质软棉球,蘸取适量的丙酮或高存度酒精,轻轻地按顺时针方向从镜片的中心旋转着擦向边缘。有必要时镜片的两面都需要清洁,擦洗时应小心细致;

 

3.装好镜筒和气嘴,调整好焦距,旋紧紧固螺丝,聚焦镜安装时请务必保持凸面向下。

 

保养激光切割机的聚焦镜片要注意以下三点:

 

1.聚焦镜片材料为ZnSe(锌化砷),比较脆,怕摔;在拆装时要注意:不能过于用力,不能和硬物发生碰撞。表面有增透膜,怕污染、怕湿、怕油性、怕刮擦;故要求在工作中提供干燥、去油的空气,千万不要直接用手处理激光切割机聚焦镜的镜片,因为皮肤油脂会对镜片表面产生永久性的伤害。相反的,您可以带手套及其专用套具进行操作,对更小的镜片,使用光学镊子或真空镊子会更方便。不管用什么方法来夹激光切割机聚焦镜,只能沿非光学表面夹持,比如镜匾边的磨砂边缘。

 

2.一般情况下,在使用前和清洁的前后都需要检查激光切割机聚焦镜的情况。因为大多数污染物和表面缺陷的尺寸比较小,在检查镜片时我们经常需要用到放大设备。除了放大设备,有时我们还需要用一束比较亮的光来照射光学表面,增强表面污染物和缺陷的镜面反射强度,这样可以更容易地发现污染物和缺陷。

 

3.当清洁一个激光切割机聚焦镜时,经常使用干净的擦拭纸和光学级别的溶剂,以防止被其他污染物破坏。擦拭纸必须用合适的溶剂润湿,千万不能干燥使用。处于对柔软度的考虑,可用的擦拭纸为纯棉的Webril擦拭纸或者棉球,镜头纸,和棉签等涂敷器。

 

虽然,清洁保养激光切割机的聚焦镜片是件麻烦事,但是,良好的清洁保养操作,能够延长镜片的使用寿命,对企业来说能够提高效率节省成本,可谓事半功倍。当清洁多次过后仍然达不到很高的洁净度时需注意更换,保证激光切割机的加工效率,以免耽误生产。
