采用喷射钻加工,可获得高精度的孔,其光洁度可达▽_6-▽_9,椭圆度达0.005毫米左右,工效比单刃硬质合金深孔钻高4—8倍。喷射钻削另一优点是它可以不必采用工件端面密封方式,即能进行钻削。我厂加工40MnB材料,平均刀具寿命在8米以上,已定型投入成批制造,现将我们的浮浅认识总结如下。一、切削齿的分配喷射钻φ20以上都采用多齿、错齿的方法来实现切削的,这样给散热和排屑创造良好的条件,同时便于力的平衡,使切削力减少,给加工质量带来好处,消耗的功率也相对减少。所以切削齿分配的好坏直接影响到刀具寿命、
The use of jet drilling, access to high-precision holes, the finish up ▽ _6- ▽ _9, ovality of about 0.005 mm, the efficiency of 4-8 times higher than single-edged cemented carbide deep hole drilling. Another advantage of jet drilling is that it allows drilling without the need for a workpiece end seal. I plant processing 40MnB material, the average tool life of 8 meters or more, has been put into mass production stereotypes, we now summed up the superficial understanding is as follows. First, the distribution of cutting teeth Jet drills φ20 above are used multi-tooth, the wrong tooth method to achieve cutting, so as to create good conditions for cooling and chip removal, and ease of force balance, cutting force to reduce the processing quality To benefit, the power consumption is also relatively reduced. Therefore, the distribution of cutting teeth directly affect the tool life,
