Welcome to inquire! Contact: Yuan Xi Chuan. Nineteenth century, the best mechanic should count Whitworth (full Mingyuesefu · Whitworth), who in 1834 made the measuring machine multi-axis drilling, the measuring machine can measure the length of the error extremely about one inch. The principle of this measuring machine and multi-axis drilling micrometer same price, by rotating the indexing plate can be out of the thread clamped workpieces, using sliding scale readout indexing indexing plate. In 1835, Whitworth invention hobbing in his 32 years of age. In addition to multi-axis drilling equipment, Whitworth also designed the inner circle and outer circle measuring cylinder plug and ring gauges. All the recommendations of machine tool production industry have adopted the same standard thread sizes. Later, the British Standards Institute to develop industry accepted this proposal, and since then until today, such as a standard threaded screw is used by various countries. As a cornerstone of modern industrial CNC multi-axis drilling machine tool industry, the industrial economic development process in any case can not bypass a critical issue, Chinese machine tool industry as a result of deficiencies, has been in the high-end machine development projects fall in foreign mainstream level, positive in a catch-up process. China CNC machine tools is still lagging behind. China CNC machine tool market is huge, compared with foreign products, China's gap is mainly on the machine's high speed and efficiency and precision, China is in the middle of industrialization, from solving the shortage mainly open gradually to build economic power shift from poverty change to become rich, coal, automobile, steel, real estate, building materials, machinery, electronics, chemicals and a number of strong heavy industry-based, high-growth industry momentum, constitute a huge market demand for machine tools, especially CNC machine tools.
