In today’s highly developed manufacturing industry, external broaching machines have become indispensable and important equipment in the field of mechanical processing due to their unique processing capabilities and excellent performance. <\/p>
Whether it is aerospace parts pursuing high precision or automobile manufacturing focusing on production efficiency, external broaching machines play a key role. It provides reliable solutions for external surface processing of various complex shapes, leading the continuous development of modern machining.<\/p>\n\n\n\n
An external broaching machine is a machine tool that uses a broach to cut the outer surface of the workpiece. Its working principle is that through the linear or rotational motion of the broach, multiple cutting teeth on the broach sequentially cut the outer surface of the workpiece, thereby achieving the processing of the outer surface. During the movement of the broach, the cutting teeth gradually cut into the workpiece, removing excess material, and finally obtaining the required outer surface shape and size.<\/p>\n\n\n\n\n<\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>\u0427\u0438\u0442\u0430\u0442\u044c \u0434\u0430\u043b\u0435\u0435:\u00a0<a href=\"https:\/\/broachingmach.com\/ru\/internal-broaching-machine-vs-external-broaching-machine\/\">Internal Broaching Machine VS.
