我在磨削柴油机进排气门时,把气门端头的外圆、平面、倒角在一次磨成,克服了原来分几次磨削,浪费辅助时间的缺点。工件(如图1)的技术要求如下:1)端头面对圆柱面В的不垂直度不超过0.04公厘;2)圆柱面В对气门头锥度面А的摆动不超过0.04公厘;3)А,б,В三面都要在磨床加工。加工方法如下:把砂轮修整如图2的样子。砂轮是中等硬度 When I was grinding diesel engine intake and exhaust valve, the valve end of the outer circle, plane, chamfer grinding at once, to overcome the original points in several grinding, wasting auxiliary time shortcomings. Workpieces (Figure 1) technical requirements are as follows: 1) the end face of the cylindrical surface of the non-perpendicularity of В does not exceed 0.04 mm; 2) cylindrical surface of the valve head taper angle А swing not more than 0.04 mm; 3 ) А, б, В all three sides in the grinder. Processing methods are as follows: The dressing wheel as shown in Figure 2. Wheel is medium hardness
