自动车床用OBS扁钻的特点

[2016-11-17 15:49:28]

扁钻是自动车床上常用的钻头,特别是对于铜类,铝类,材质较软的材质上对孔径的光洁度各孔径公差要求严格上选择OBS扁钻是一种不错的选择。

扁钻是经过圆棒对切削部分磨成一个扁平体,主切削刃磨出锋角,副切削磨出后角中,副偏角控制钻孔直径,OBS扁钻前角小,没有螺旋槽,制造简单,成本低等特点特别对小孔加工上得到广泛的应用。

扁钻的切削部分为扁体结构简单,切削润滑油能轻易导入孔中,但切削各排屑较差,扁钻的结构分为整体各焊接式丙种,整体费用较高,焊接式后部为工具钢材料价格低。

因为OBS扁钻钢性好,对于孔径提高,光洁度各加工精度有重要应用,在自动车床深孔加工占有重要地位。

今天给大家分享一下怎么选对钻头,

今天给大家分享一下车削什么材质选什么样的钻头,曾经有客户问我你家OBS镀钛左钻都打什么材料好用啊,我会很干脆的说不锈钢,快削铁,因为连最硬的材质都可以切削那稍软的材料就很轻松的切削了,要不然就拿铝材来说吧,虽然软但是它比较粘刀,出来的渣也比较多容易粘在钻头上,这时我们应该在钻头尖部开一个断削槽这样就可以免去粘渣现象,如果还有的话,就多退几次凸轮就可以了.
