车削铸铜和铸铁等类工件时,因碎末四处飞溅,影响安全生产和车间卫生,也不利于铜屑的回收。为此,革新成一种机夹聚屑车刀。该刀具制造容易,使用方便。刀具结构为机械夹固式,如图所示。刀杆为45钢;刀片采用YG8N硬质合金。刀具前角为2°～3°,并附加一个30°大前角。 Turning cast copper and cast iron and other types of workpieces, due to splinters scattered around, affecting the safety of production and workshop health, but also conducive to the recovery of copper scrap. To this end, innovation into a folder-chip turning tool. The tool is easy to manufacture and easy to use. Tool structure for the mechanical clamping, as shown. Arbor 45 steel; blade YG8N carbide. Tool rake angle is 2 ° ~ 3 °, and attached a 30 ° rake angle.
