机械产品的质量不仅决定于另件的尺寸、形状以及位置误差,在很大程度上还取决于零件的表面质量。表面粗糙度是零件表面质量的重要内容,它对零件的使用性能有很大影响。新国标GB3503—83已于1985年1月1日实施。而现有的表面粗糙度测定仪大都只能测量个别参数,这给新国标的贯彻带来了困难。作者建立了一个由国产BCJ—2型轮廓仪和苹 The quality of a mechanical product depends not only on the size, shape and position of the other part, but also on the surface quality of the part. Surface roughness is an important part of the surface quality, which has a significant impact on the performance of parts. The new national standard GB3503-83 was January 1, 1985 implementation. However, most existing surface roughness testers can only measure individual parameters, which brings difficulties to the implementation of the new national standard. The author established a home made BCJ-2 profiler and Apple
