铰刀直径为铰刀设计中最重要的构成部分,因它直接决定着被加工孔的尺寸与精度。决定铰刀直径的尺寸时需考虑下面三个因素: (1)扩大量:在铰孔时由於机床、刀具与夹具等的振动,必然促使铰后之孔较铰刀本身稍大一些,故铰刀上限差须比工件上限差低一最大扩大量,其值与实际工作条件?

The reamer diameter is the most important part of the reamer design because it directly determines the size and accuracy of the hole being machined. Determine the size of the reamer diameter to consider the following three factors: (1) to expand the amount: Reaming due to machine tools, tools and fixtures and other vibration, will inevitably promote the hinge hole slightly larger than the reamer itself, so the hinge Upper limit of the difference between the upper limit of the workpiece should be lower than the maximum amount of expansion, the value of the actual working conditions?
