Welcome to inquire! Contact: Yuan Xi Chuan. Machine prototype of the fifteenth century, the need for manufacturing watches and weapons, there has been a watchmaker with a thread lathes and gear cutting machines, and hydraulic-driven barrel boring. Around 1501, the Italian Leonardo da Vinci who had the idea to draw a sketch lathe, boring machine, threading machine and grinder inside, where there are crank, flywheel, bearings top and new institutions. China Ming book "Heavenly Creations" also contains a dedicated grinder axle shaft drilling supply structure, with foot iron disc rotation method, plus sand and water to cut jade. Industrial Revolution led to a variety of machine tools to produce and improve the industrial revolution of the eighteenth century to promote the development of the machine. In 1774, Englishman Wilkinson (full name John Wilkinson) invented a more sophisticated barrel boring. The following year, he used this boring boring out of the cylinder barrel to meet the requirements of the Watt steam engine. In order to make a larger cylinder bore special axle shaft drilling, he manufactured a water wheel driven cylinder boring machine in 1775, to promote the development of the steam engine. Since then, the machine began to drive a steam engine by the crankshaft. The world's first controlled production line was born (1968) in 1968 dedicated axle shaft drilling machine manufacturers, British wool Springs machinery company has developed the first automatic line consisting of CNC machine tools, and soon, the US General Electric Company proposed the "Factory Automation prerequisite is part of CNC machining process and production processes programmed ", so, by the mid-1970s, there has been automated plant, factory automation has also started construction. 1970-1974 special axle shaft drilling products, due to a small computer controlled machine tools are widely used, there have been three technological breakthroughs. The first is the direct digital controller, so that a small computer to control multiple machines at the same time, a "control group"; the second is a computer-aided design, with a light pen to design and modify the design and calculation procedures; s Three are processed according to the actual situation and unexpected changes in the amount of feedback and automatically change the machining and cutting speed, there has been an adaptive control system for machine tools. After 100 years of ups and downs, family machine has become more mature, and truly become the mechanical field, "workhorses."
