在机器制造工业中,为了保证产品零件符合规定标准和技术要求,使零件达到充分的互换性,因此在生产过程中必须使用各种不同精度的量具和仪器来测量。这些量具和仪器一定要经常地使用最精密的量具来校核和调整。这种最精密的量具就是我们通常所说的量块(又叫做规矩块、对板、千分墊或平行平面端度器)。量块不但用来校核和调整各种量具和仪器,也可以直接测量极精密工件。所以,量块是工厂中最精密、最高级的量具,也是工厂中长度测量中的基准,假使量块不准确,选择和使用不恰当,都会使生产上遭到损失。因此,在使用量块时应该给予最大的重视。
In the machine manufacturing industry, in order to ensure product parts meet the required standards and technical requirements, to achieve full interchangeability of parts, so in the production process must be used to measure a variety of different precision gauges and equipment. These gauges and instruments must always be checked and adjusted using the most accurate gauges. This most sophisticated measuring tool is what we usually call the measuring block (also known as the rule block, on the board, thousand pad or parallel plane end-device). Measuring block is not only used to check and adjust a variety of measuring instruments and instruments, but also can directly measure very precise workpiece. Therefore, the measuring block is the most precise and highest quality measuring tool in the factory, and also the reference in the middle length measurement of the factory. If the measuring block is inaccurate, the selection and use are not appropriate, the production will be lost. Therefore, the use of measuring block should give the greatest attention.
