机床导轨在使用过程中,因使用保养不当,常会产生划伤或拉毛现象,这时需要进行修复。过去,我们常采用环氧树脂粘补等方法进行修复。自去年11月份起我们又开始采用将刷镀技术与钎焊结合起来修复导轨划伤的方法。经实践证明,修复效果较为理想。采用这种修复方法具有修复速度快、成本低、变形小、结合强度好、钎焊表面镀后硬度较高且耐磨等特点。下面就以我们车间的T611卧式镗床为例,介绍一下具体修复工艺过程。
Machine tool rails in the course of use, due to improper use of maintenance, often scratch or nap phenomenon, then need to be repaired. In the past, we often use epoxy adhesive repair methods such as repair. Since November last year, we have started to use brush plating technology and brazing together to repair the rail scratch. Practice has proved that the repair effect is more ideal. Using this method of repair has the advantages of fast repair, low cost, small deformation, good bonding strength, high brazing hardness after brazing and wear resistance. The following to our workshop T611 horizontal boring machine, for example, introduce the specific repair process.
