机车动轴箱瓦圆加工,国内多在插床上进行,国外也有用圆盘立铣先铣出圆弧部份后,再由插床完成瓦角部份加工的工艺方案. 使用插床加工,生产效率低,不能满足产量日益增长的需要,且我厂插床能力不足,现有插床又多为液压插床,连续工作时间较长时,油温升高,泄漏严重,必须停车降温,严重影响生产.目前尚未能找出有效措施来根除机床的缺陷.若采用第二种方案加工,圆柱铣刀过
Locomotive rolling mill box round, more than the domestic machine in the slot, the other is also useful for circular milling milling circular arc part, and then by the slotted tile corner to complete part of the processing program. The use of slotting machine processing, production efficiency Low, can not meet the needs of growing production, and I plant capacity is insufficient, the existing slotted bed and more for the hydraulic slot, continuous working time is longer, the oil temperature, serious leakage, cooling must be stopped, seriously affecting the production. Yet to find effective measures to eradicate the defects of the machine tool.If the second program processing, cylindrical cutter too
