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 has been drawn over the lathe, boring machine, screw machine tools and internal grinder CNC machine tools price sketch idea, which has a crank, flywheel, bearings top and new institutions. China Ming book "Heavenly Creations" also contained grinder structure, with the foot of the iron plate 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, 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. Industrial technology development center, from the nineteenth century onwards CNC machine tool manufacturers, quietly toward the United States from England. England won the prestigious past of those technologies, Whitney called the leader. Whitney intelligent man, a visionary, he was the first to come up with a system of mass production of replacement parts. Whitney has been very active engineering company, early in the 19th century, the 1940s successfully developed a hexagonal turret lathe. This lathe with the workpiece making the complex and refined products and the advent of CNC machine tools in the tool in such a lathe CNC machines, equipped with a winch, a variety of needs are installed on the winch, so that by rotating turret fixed tool, you can put the tool to the desired position. With the invention of the electric motor, the machine start by using a motor-driven focus, then widely used alone motor.
