在使用铰刀时,常常发现:如果它的直径比某一尺寸稍许大一点或者小一点的话,则铰出的孔径将会更理想。如图所示,用一块淬硬的刀头或硬质合金沿着刀槽、对着切削刃用力划过去。铰刀直径就会增大0.025～0.075mm。增量大小与用力程度成正比。但其力度应尽可能均匀。如果,想要使铰刀直径小一点的话,则可将铰刀夹在机床的主轴上,在其旋转的同时,用一块平油石使劲靠着切削刃,一会儿即可达到目的。当然,这种调整法对于再生旧铰 When using reamers, it is often found that if its diameter is slightly larger or smaller than a certain size, the hinged aperture will be more desirable. As shown, use a hardened tip or carbide along the sipe and force it against the cutting edge. Reamer diameter will increase 0.025 ~ 0.075mm. Incremental size and the degree of effort is proportional. But its intensity should be as uniform as possible. If you want to make the diameter of the reamer smaller, you can clip the reamer on the main shaft of the machine and rotate it with a flat stone against the cutting edge for a while. Of course, this adjustment method for the regeneration of the old hinge
