带表外径千分尺用于测量大中型工件外尺寸的高精度量具。它的主要优点是:可以用微分筒一端和表头一端分别是进行工件尺寸的测量。尤其是使用表头一端测量时,读数更直观、方便,并具有刚性好、变形小、精度高的特点。
其技术要求执行企业标准。
The outside micrometers with dial indicators are a high precision
tool used to make the outside measurement of large-sized and
medium-sized workpieces.Their main advantage is that the
measurement of the dimensions of workpieces can be made either by
means of the dial indicator or by means of the micrometer
head.Especially,when the measurement is made by means of the dial
indicator,reading is more direct and convenient,and the
measurement also has the features of good rigidity,small
deformation and high accuracy.
Their
technical specifications conform to the standard of the
enterprise.
