Description
技术领域technical field

现有的产品上螺纹孔采用各种机床的加工：比如钻床，车床、镗床……以钻床加工少量螺孔工艺为例，普通钻床定位误差较大，一般都是将一个孔加工完成后再做另一个孔，以保证孔的形位精度：1，首先确定螺孔的中心位置，比如划线、样板、钻模……2，以划线为例，先钻螺纹底孔。3，扩孔，4，锪孔，加工直径最大的沉孔。5，攻丝。6，加工下一个螺孔。The threaded holes on existing products are processed by various machine tools: such as drilling machine, lathe, boring machine... Take the process of drilling a small number of screw holes as an example. The positioning error of ordinary drilling machine is relatively large, and it is generally done after a hole is processed. Another hole, to ensure the shape and position accuracy of the hole: 1. First determine the center position of the screw hole, such as marking, template, drilling template... 2. Taking marking as an example, drill the threaded bottom hole first. 3, reaming, 4, countersinking, processing the countersinking with the largest diameter. 5. Tapping. 6. Process the next screw hole.
车床一般加工轴端螺孔，就要以外圆为基准确定中心孔位置，然后在钻扩攻丝。坐标镗床可以方便的定位，所以，先打所有孔的中心孔，然后再钻所有孔的底孔，在扩所有孔……，减少换装刀具的时间，提高效率。机械加工千变万化，不要拘泥于一种单一工艺，要综合多方面的因素，制定最适合自己工作环境的加工方法。When lathes generally process the screw holes at the shaft end, it is necessary to determine the position of the center hole based on the outer circle, and then drill and tap. The coordinate boring machine can be positioned conveniently, so first drill the center holes of all the holes, then drill the bottom holes of all the holes, and then expand all the holes..., reducing the time for changing tools and improving efficiency. Mechanical processing is ever-changing, so don't stick to a single process, but integrate various factors to formulate the processing method that is most suitable for your working environment.
