高速铰孔工艺,五十年代就在世界各国逐步推广和使用,近年来仍为各国重点推广和扩大使用的先进工艺之一。它具有以下优点:1、可获得较高的内孔表面光洁度(高达▽10),尺寸精度可稳定在2级(GB159～59);2、适宜于深孔铰削;3、工效高,普遍可提高2～4倍,有的高达几十倍;4、铰削后可改善内孔的表面质量;5、操作简便,使用时不需多次修磨。高速铰孔的优点决定了它是内孔表面光洁
High-speed reaming process, the fifties in the world gradually promote the use and use in recent years is still focused on the promotion and expansion of the use of advanced technology. It has the following advantages: 1, get a higher surface finish of the hole (up to ▽ 10), dimensional accuracy can be stabilized at 2 (GB159 ~ 59); 2, suitable for deep hole reaming; Can be increased 2 to 4 times, and some up to several times; 4, after reaming can improve the surface quality of the hole; 5, easy to operate, do not need to use multiple grinding. The advantages of high-speed reaming determines that it is a smooth surface of the hole
