在我厂设备维修与工具制造的单件小批生产中,经常会碰到各种规格结构的孔。由于不可能都设计专用刀具,只好依靠操作者的熟练程度去掌握镗孔精度,因此精度不易控制。为此,设计制造了微调万能镗头(见图1)。该镗头可以在铣床、镗床、车床及具有一定刚度的钻床上镗削φ10～φ100毫米、长100～150毫米的通孔与不通孔,并能使刀架6在旋转过程中作径向进给,以 In our factory equipment maintenance and tool manufacturing single small batch production, often encounter a variety of standard structure of the hole. Since it is impossible to design a dedicated tool, we have to rely on the proficiency of the operator to master the boring accuracy, so the accuracy is not easy to control. To this end, the design and manufacture of fine-tuning universal boring head (see Figure 1). The boring head can boring φ10 ~ φ100 mm and length of 100 ~ 150 mm through holes and non-through holes in the milling machine, boring machine, lathe and the drilling machine with certain rigidity, and can make the tool holder 6 to make radial direction during the rotation give
