Who made the first machine tool in the world?

The first machine tool in the world was invented by John Wilkinson, an Englishman.

Brief introduction of machine tool history:

In p>1774, John Wilkinson, an Englishman, invented a more precise barrel boring machine. The following year, he used this barrel boring machine to bore out the cylinder, which met the requirements of Watt steam engine. In order to bore a larger cylinder, he made a cylinder boring machine driven by a water wheel in 1775, which promoted the development of the steam engine. Since then, machine tools have been driven by steam engines through crankshafts.

In p>1797, the lathe made by Maudslay, an Englishman, was driven by a lead screw, which could realize the motorized feed and thread turning, which was a major change in the structure of the machine tool. Maudslay is therefore called "the father of British machine tool industry".

in the 19th century, due to the promotion of textile, power, transportation machinery and arms production, various types of machine tools appeared one after another. In 1817, the Englishman Roberts created the planer. In 1818, American Whitney (his full name is eli whitney) made a horizontal milling machine; In 1876, the United States made a universal cylindrical grinder; In 1835 and 1897, gear hobbing machine and gear shaper were invented successively.

The best mechanic in the 19th century should be Whitworth (full name: joseph whitworth), who made the length measuring machine in 1834. The length measuring machine can measure the length error by about one ten thousandth of an inch. The principle of this length measuring machine is the same as that of a micrometer. The workpiece is clamped by rotating the thread that can enter and exit the indexing plate, and the graduation on the indexing plate is read by using a sliding ruler. In 1835, Whitworth invented the gear hobbing machine at the age of 32. In addition, Whitworth also designed plug gauges and ring gauges for measuring the inner and outer circles of cylinders. It is suggested that all machine tool manufacturers adopt standard threads of the same size. Later, the British Industry Standards Association accepted this proposal, and since then, this thread has been used as a standard thread in various countries.
