我厂分厂一台车床于1990年5月由于润滑系统故障及保养不善,造成干摩擦,主轴严重磨损,径跳达0.15mm以上。为了能继续使用,我们进行了修理,其补救的方法是将主轴锥度(被磨损部分)部分镀上0.30mm厚的硬铬层,然后精磨至图纸要求,配合铲刮轴瓦,精刮要求在25×25mm～2内应有12～25点接触。按着处理润滑系统故障,清洗床头箱及油泵系统的吸油管滤网,重新注入干净的30#机油。经过修复后,该车床径跳不超过0.01mm,切断力正常。如今该车床一直在正常使用,还未出现任何异常现象。为我厂节约1000多元并赢得宝贵的时间使生产
I plant a lathe factory in May 1990 due to lubrication system failure and poor maintenance, resulting in dry friction, the spindle serious wear and tear, up to 0.15mm diameter. In order to be able to continue to use, we conducted a repair, the remedy is the spindle taper (worn part) is plated with 0.30mm thick hard chrome layer, and then fine grinding to the drawing requirements, with scraping pad, 25 × 25mm ~ 2 should have 12 to 25 points of contact. In accordance with the lubrication system failure, cleaning the headstock and pump system suction pipe filter, re-injection of clean 30 # oil. After repair, the lathe diameter does not exceed 0.01mm, cutting force normal. Now the lathe has been in normal use, has not yet appeared any anomalies. I saved more than 1,000 yuan plant and won valuable time to make production
