在轴,套零件的外圆车削中,常常会遇到精车后零件的加工余量还剩0.01—0.02毫米,这时再用普通外圆精车刀车削是较困难的,若用砂布打、或锉刀锉则会使零件的几何精度超差,为此,我们没计制造了微量切削精车刀。 焊有YT15或YT30硬质合金刀片的刀头与刀体采用滑配合,由螺栓固紧。刀体与开有3毫米宽通槽的方套采用滑配合并装在刀架上,其特点是: 1.主后角和前角、刃倾角和副后角、主偏角和副偏角均可调节,主后角和前角由转动刀体来调节;刃倾角和副后角由转动刀头来调节;主偏
In the shaft, sleeve parts of the external turning, often after finishing the remaining parts of finishing after the remaining 0.01-0.02 mm, then use ordinary cylindrical turning turning more difficult, if the fight with emery cloth , Or rasp file will make the geometric accuracy of the parts out of tolerance, therefore, we did not count the manufacture of micro-cutting fine turning knife. Welded YT15 or YT30 carbide blade blade and body with a sliding fit, bolted. The cutter body and the square sleeve with the 3 mm wide through slot are matched with each other and fitted on the knife holder. The utility model is characterized in that: 1. The main posterior horn and the rake angle, the rake angle and the sub-posterior horn, the main declination and the declination Can be adjusted, the main posterior horn and rake angle by rotating the blade body to adjust; edge angle and deputy after the angle by the rotating blade to adjust; the main deviation
