    • PURPOSE:To cut a cylindrical surface with high accuracy using no special cutting machine by a construction wherein a plurality of bits symmetrical about a center axis are formed at the end of a tubular shank, and the bits comprise a bite face substantially parallel to the plane passing the center axis and a flank having a necking slope relative to the plane perpendicular to the center axis. CONSTITUTION:A shank part (b) is attached to the chuck of a driller or the rotatable section of a lathe. With the shank part being fed in a similar way to drilling, a material 7 to be cut is cut with bits 5-1, 5-2 to form the cylindrical surface of diameter D. The part of the cylindrical surface of diameter D and a land (i) are fitted with each other in a sliding relation to hold the center axes of the cut material 7 and cutting tool in a concentric state. Because the cut material 7 is cut by two bits 5-1, 5-2 symmetrical about the center axis (d) simultaneously, there causes no bending deformation.
    • 目的:使用不需要特殊切割机器的高精度切割圆柱形表面,其中在管状柄部的端部形成有围绕中心轴对称的多个钻头,并且该钻头包括基本上平行于该平面的咬合面 通过中心轴线和相对于垂直于中心轴线的平面具有颈缩斜面的侧面。 构成:柄部分(b)连接到司钻的卡盘或车床的可旋转部分。 以与钻孔相似的方式进给柄部分,用钻头5-1,5-2切割要切割的材料7以形成直径D的圆柱形表面。直径D的圆柱形表面的部分和 焊盘(i)以滑动关系彼此配合,以将切割材料7和切削工具的中心轴保持在同心状态。 因为切割材料7被同时围绕中心轴线(d)对称的两个位5-1,5-2切割,所以不会产生弯曲变形。
