为了提高镗床的生产率,往往装备自动机构,但随之而来的问题是由于切屑的自动排出困难,时常发生损伤刀具和加工表面。如果采用以往既简单又方便的断屑槽,又受切削条件的制约,当切削量,进给量等参数变化时便立即影响断屑的性能。此外,断屑槽往往对难加工材料难以奏效,而且,主要问题是断屑槽的磨损比刀尖的磨损还快。 In order to improve the productivity of the boring machine, often equipped with automatic mechanism, but the attendant problem is due to the automatic discharge of chips difficult, often damage the tool and the machining surface. If the past is both simple and convenient chip breaker, but also by the constraints of cutting conditions, when the cutting amount, feed and other parameters change will immediately affect the chip breaking performance. In addition, chip breakers tend to work harder on difficult-to-machine materials, and the main problem is that chip flutes wear faster than tip wear.
