φ6～φ10.5mm锥柄麻花钻具有柄部大、工作部份细长的特点。但整体加工时要消耗大量工时,又极易产生弯曲变形。因此,绝大多数工具厂都未认真安排过生产。但是,随着工业生产的发展,越来越多的工厂使用多轴组合钻床,迫切需要小规格的锥柄钻头。为此,我厂试制和生产了镶装锥柄麻花钻头。一、镶装锥柄钻的结构参数镶装锥柄钻的结构如图1所示。钻头工作部分与
φ6 ~ φ10.5mm taper shank twist drill has a large handle part of the slender features. However, when the overall processing consumes a large number of working hours, it is also prone to bending deformation. Therefore, most tool factories did not arrange production seriously. However, with the development of industrial production, more and more factories use multi-axis combined drilling machines, and the urgent need for small-sized taper shank drill bits. To this end, I plant trial production and production of taper shank twist drill bits installed. First, the installation parameters taper shank drill mounted taper shank drill structure shown in Figure 1. Drill part and work
