    摘要： A cutting stylus adapted for mechanically cutting a deep groove, which may be used in lapping the keel on a playback stylus, is provided. The stylus includes a tapering body, a constricted terminal region and shoulders joining the tapering body and the constricted terminal region. The shape of the constricted terminal region is complementary to the shape of the keel tip on the playback stylus. The terminating portion of the stylus tip has a substantially flat cutting face, a pair of side surfaces extending from the side cutting edges of the cutting face which taper at a slight angle to provide clearance to the side cutting edges, and a bottom surface extending from the bottom cutting edge of the cutting face at an angle which provides relief to the bottom cutting edge.

    摘要翻译： 提供了一种用于机械切割深槽的切割触针，其可用于在重放触针上研磨龙骨。 触笔包括锥形主体，收缩端子区域和连接锥形体和收缩端子区域的肩部。 收缩端区域的形状与重放触笔上龙骨尖端的形状互补。 触针尖端的终端部分具有基本上平坦的切割面，从切割面的侧切割边缘延伸的一对侧表面，其以微小的角度逐渐变细，以提供与侧切割边缘的间隙， 切割面的底部切割刃以向下切割刃提供缓冲的角度。
