浅析线切割加工中存在的问题及对策

对在线切割加工中影响工件表面质量的主要原因———送丝机构故障、电参量选择、操作不合理等作了分析 ,并对工件表面加工精度差的具体表现———加工表面粗糙、有条纹、拐角处精度差、加工面平直度差、鼓形、模具产生裂纹等原因作了详细的分析 ,提出了相应的措施。

An Brief Analysis of the Problems Existing in Wire Cutting and the Countermeasures

The main factors in wire cutting affecting the surface quality of the parts such as the failure of the thread feeding mechanism, selection of the electric parameters and irrationality of operation were analyzed. Low processing precision of the part surface might cause rough processing surface, stripes on the surface, low precision at the corner part, poor flatness of the surface, bulging, or cracks in the moulds. The reasons for causing these defects were analyzed in detail and the corresponding improving or avoiding measures were proposed.
