手工刃磨钻头是在砂轮上进行的,因此对砂轮应有如下要求:
(1)选用粒度适当的(46#~80#)中软级(ZRl~ ZR2)砂轮。
(2)砂轮旋转时跳动要小。
具体刃磨步骤如下:
(1)将主切削刃置于水平状态并与砂轮外圆平行。
(2)保持钻头中心线与砂轮外圆面的夹角为Φ)。
(3)用右手握钻头头部,作定位支承并加刃磨压力。
(4)左手握钻头柄部,协助右手作上下摆动(目的:磨后角)。
(5)左右两手的动作必须很好配合协调一致。
(6)刃磨时,由上向下或由下向上都可。
(7)一面磨好后,翻转 180°磨另一面(磨法同上)。
在刃磨过程中主切削刃的锋角、后角和横刃斜角都是同时磨出的。钻头刃磨后可用样板进行检查,一般常用目测法进行检查。目测时,将钻头竖起,立在眼前,两眼平视,观看刃口,这时背景要清晰。因为观察时两钻刃一前一后,会产生视差,观看两钻刃时,往往感到左刃(前刃)高。这时将钻心绕轴线旋转180°,这样反复几次,如果看的结果一样,就证明对称了。另外钻头刃磨时,为防止切削部分过热而退火,应经常浸入水中冷却。
钻头的顶角的选用一般是硬材料取大点,可以到130-140度,软材料小点90--100度,标准的是118度.
