Domestic measuring tool is bright
From visual measurement to simple measurement to precision measurement, the progress of measurement technology ensures the progress of manufacturing technology. Mr. Qian xuesen, a famous scientist, also pointed out that information technology includes measurement technology, computer technology and communication technology. Measurement techniques are key and fundamental.
The director of China machine tool industry association told the author that precision machining and manufacturing not only needs the precision and stability of machine tools, but also the precision of tools and clamps to ensure, as well as the precision of precision measuring instruments to calibrate and measure. Some are in the process (such as tool alignment); Some tests are done after the fact (e.g., gear measuring instruments).
