外径可微调的硬质合金机用铰刀,其结构如图所示。制造简单,只要在一般同类型铰刀的头部,加工一1:50的锥孔,然后,配上一只带内螺纹圆锥销即可。锥销大小视铰刀的外径而定,既不能太大,也不能过小,如外径25毫米的铰刀,锥销可选φ10毫米左右(指小端尺寸)。经我厂多年使用证明,效果显著。刀具主要特点为: Diameter can be fine-tuning carbide reamers, the structure shown. Simple to make, as long as the head of the same type of reamer, machining a 1:50 tapered bore, and then, with a tapered female pin can be. Cone pin size depends on the outer diameter of the reamer, neither too much nor too small, such as 25 mm outer diameter reamer, cone pin optional φ10 millimeter (referring to the small end size). After years of using our factory to prove that the effect is remarkable. The main features of the tool are:
