机床在使用过程中,导轨面的研伤现象是经常发生的。近年来,我们将还原铸铁粉与 KH579粘接剂混和,用来修复了6m 刨床、5m 车床等机床严重磨损的导轨。粘补沟槽最大长度2m、槽宽4mm、槽深3mm,浅的为0.2～0.4mm,经三年多的使用,证明放果良好。现将粘补工艺介绍如下:一、粘补材料(1)填充剂:采用的还原铸铁粉为160～200号,视研伤部位深浅和面积大小而定。(2)粘接剂:采用 KH579粘接剂。它可在100～120℃温度下长时间使用。对于受高温辐射和高速运行的导轨,使用该胶较为理想。该胶在非金属之间、金
Machine tool in use, the track surface of the phenomenon of injury is often happen. In recent years, we will restore the cast iron powder and KH579 adhesive mixing, used to repair the 6m planer, 5m lathe and other serious wear and tear of the machine rail. The maximum length of sticking trenches is 2m, the groove width is 4mm, the groove depth is 3mm, and the lightness is 0.2 ~ 0.4mm. After more than three years of use, it proves that the putting fruit is good. Now sticky process introduced as follows: First, the sticky material (1) filler: The use of reduced cast iron powder 160 to 200, depending on the depth of injury site size and size may be. (2) adhesive: KH579 adhesive. It can be used for a long time under the temperature of 100 ~ 120 ℃. For the high temperature radiation and high-speed rail operation, the use of the plastic is more ideal. The glue in the non-metallic, gold
