用新技术加工孔是很有前途的方法。它不仅可以提高穿透率和循环次数,而且能大大降低对操作、必需设备和刀具安装的要求,还能大大缩短非切削时间。 对于一般的箱形零件,孔的加工及精加工(铰、镗和攻螺纹)要花费加工周期的80％。为了有效地减少这一大块时间,切削时间和非切削时间都必须缩短。 为了中、大批零件的生产者,R＆D的很多工作都是研究在加工中心上进行切实可行的和生产性的钻孔和孔 Hole processing with new technology is a promising method. Not only does it increase the penetration and the number of cycles, it also drastically reduces the need for operation, necessary equipment and tooling, and greatly reduces non-cutting time. For ordinary box-shaped parts, hole machining and finishing (hinge, boring and tapping) takes 80% of the machining cycle. In order to effectively reduce this large time, cutting time and non-cutting time must be shortened. For a large number of parts producers, much of R & D’s work is to study practical and productive drilling and holes in machining centers
