块规在测量产品时,都是作为比较测量用的,有时为了测量距离,用手来感觉其紧松程度,决定其尺寸合格与否,因而准确性较差,测量效率亦很低。尤其检查大尺寸时,上述缺点更为显著。 我厂创制了一种读数块规,使用时在工作面“A”处研上所需的块规;“B”面有一刀形的测量头1,可以与被? Block gauge in the measurement of products, are used as a comparative measurement, and sometimes in order to measure the distance, feel the tightness of their hands to determine its size or not, so the accuracy is poor, the measurement efficiency is very low. In particular, check the large size, the above shortcomings even more significant. I plant created a reading block rules, when used in the work surface “A” to study the required block rules; “B” surface has a knife-shaped measuring head 1, can be?
