深孔单刃铰削加工是采用新型结构的硬质合金单刃铰刀对深孔零件进行精加工的一项技术(已申请专利)。特点为单刃切削,主切削刃由两段两个锥角组成。单刃铰刀上有分布合理的两块或两块以上的导向块,工作时起支承和挤压作用,所以铰削过程是切削与挤压相结合的综合性加工,从而可获得高精度、低表面粗糙度和高的生产效率.其尺寸精度可稳定在H8或 H7;表面粗糙度可稳定在 Ra0.4,最好可达
Deep-hole single-edged reaming is the use of a new structure of carbide single-edged reamer deep hole parts for finishing a technology (patented). Features a single-edged cutting, the main cutting edge consists of two sections of two cone angle. Single-edged reamer on the distribution of a reasonable two or more pieces of the guide block, work from the support and extrusion, so the reaming process is a combination of cutting and extrusion machining, which can be high-precision, Low surface roughness and high production efficiency of its dimensional accuracy can be stabilized at H8 or H7; surface roughness can be stabilized at Ra0.4, the best reachable
