我厂的C7632多刀半自动车床,主要用于各类气缸套外圆的粗车及半粗车加工工序。吃刀量大,效率高。但存在着一个明显的缺点就是各导轨、拖板磨损剧烈,且拉伤较严重。究其原因,除了生产负荷大以外,主要还是润滑不好。 该设备各滑动面均是压注式油杯润滑,每班一次所加的油满足不了摩擦副所需要的用量;尤其是下刀架润滑更差,加工中有许多切屑、尘泥、冷却水等杂物落在刀架上,虽有护罩但杂物还是很容易进入滑动面,从而加剧磨损,甚至拉伤导轨。而且油杯常被油泥、铁 I plant C7632 multi-knife semi-automatic lathe, mainly for all types of rough cylindrical and semi-rough cylinder machining processes. Eat a large amount of knife, high efficiency. However, there is an obvious shortcoming that all the guide rails and drag plates wear heavily and the tension is serious. The reason, in addition to the large production load, the main or poor lubrication. The sliding surface of the device are pressure-type grease cup lubrication, the oil added to each class can not meet the friction required by the amount required; In particular, under the blade lubrication worse, processing, there are many chips, dust, cooling water Other debris fall on the knife holder, although the shield but debris is still easy to enter the sliding surface, thereby increasing wear and tear, and even strain the rail. And often oily cup of oil, iron
