为增强千分尺丝杆和测砧工作部分的耐磨性,一般在其头部都焊一块硬质合金(T15K6)。但由于它的面积很小,同时又系光面与光面焊接;掌握不好;硬质合金很易随焊接剂流失,若用粗面焊接又会影响质量,因此给加工带来很多困难。我厂在制造0级千分尺寸,采取了新的方法,因而克服了上述困 In order to enhance the wear resistance of the working portion of the micrometer screw and the anvil, a hard alloy (T15K6) is usually welded on the head. However, due to its small area, but also the Department of smooth and smooth welding; mastery is not good; hard alloy is easy with the loss of solder, if the use of rough welding will affect the quality, so to the processing of many difficulties. I plant in the manufacture of 0 level thousand size, has taken a new approach, thus overcoming the above difficulties
