1.曲轴光磨前的准备一是用清洗液清洗曲轴各部位并擦干净;二是检查有无裂纹损伤;三是检测弯曲和扭曲,当主轴颈的弯曲度大于0.15 mm时,须利用专用校正器进行校正,方法是将两端的连杆轴颈转至水平位置,测出相对应的连杆轴颈高度差即扭转角,扭转很微小时可通过曲轴光磨予以修正;四是对砂
1. Preparation of the crankshaft before polishing First, clean the parts of the crankshaft with a cleaning fluid and wipe clean; the second is to check for crack damage; the third is to detect bending and distortion, when the main journal of the curvature greater than 0.15 mm, the use of special Calibrator correction method is to turn the two ends of the connecting rod journal to a horizontal position, measuring the corresponding link journal height difference that is the torsion angle, twisting a very small hour by the crankshaft optical mill to be amended; Fourth, the sand
