在设备维修工作中,对机床导轨、工作台的砸、钻、铣、拉、咬伤的修补,过去采用过很多办法,从银焊镶补,到环氧树脂铸铁粉的填补,进而发展到轴承合金(巴氏合金)钎焊及高锡基轴承合金焊补。以上各项的修补技术都存在着下列问题: 1.焊补处结合不牢; 2.焊补材料的硬度不高; 3.焊补工艺比较复杂,成本较高; 4.焊补材料与本体颜色不一。我们厂对导轨较细的拉毛仍采用高锡基轴承合金焊补,对砸、钻、铣、拉、咬伤等面积较大
In the equipment maintenance work, the machine tool rail, table drop, drill, milling, pull, bite repair, used in the past a lot of ways, from silver welding trim, epoxy resin to fill the cast iron powder, and then to Bearing alloy (Babbitt) brazing and high tin bearing alloy welding. Above all the repair techniques are the following problems: 1. welding repair Department is not strong; 2. welding repair material hardness is not high; 3. welding repair process is more complex, higher cost; 4. welding repair materials and body Different colors. Our factory on the guide rail thinner is still using high-tin-bearing alloy welding repair, smashing, drilling, milling, pulling, bites and other areas larger
