为在洛氏硬度计上测定带有斜面零件的硬度,我们设计了一种可调节斜面为平面的球面工作台,经过多年的使用证明效果良好。工作台由球面支承铁块(图1)和凹形台(图2)组成,均用50号锻钢车成,工作时两者合在一起使用,即可根据不同斜面的零件来调整水平位 To determine the hardness of a part with a bevel on a Rockwell hardness tester, we designed a spherical worktable with an adjustable bevel for a flat surface, which proved to be effective over many years. Table by the spherical bearing iron block (Figure 1) and concave Taiwan (Figure 2), are made of steel forging No. 50, the two work together to use, you can adjust the level according to the different parts of the slope
