Technical field
The present invention relates to metal cutting tool field, particularly relate to a kind of cutting tip with the combination of multiple cutting edge.
Background technology
Blade passivation generally adopts circular arc, and circular arc radius of curvature is everywhere identical, and blade intensity is everywhere also identical.
Cutting edge roundness passivation can improve cutting edge microdefect, reaches round and smooth smooth, i.e. sharp firm but also durable object.But cutting edge is not necessarily more sharp better, also not necessarily more blunt better, determine different passivation value for different processing conditions, effectively can improve cutting edge strength and improve cutter life.
When cutting workpiece be material that intensity is higher or stronger operating mode is impacted to cutting edge time, excessively sharp blade is tipping in the process of cutting easily, therefore needs larger cutting edge passivation arc radius, increases the intensity of blade, prevents the generation of tipping; When cutting operating mode is that high-speed and continuous adds man-hour, excessively blunt blade can make cutting force rise, and accelerates the rate of wear of cutting edge, causes the premature failure of blade, and less cutting edge passivation arc radius cuts more brisk.
But, the passivation value of each cutting edge of existing cutting tip is identical, and a cutting tip only can carry out roughing or fine finishining, need to carry out slightly workpiece, smart in various degree add man-hour, need to adopt multiple cutting tip, thus cause the inconvenience of use.
