Machine prototype of the fifteenth century, due to manufacturing watches and weapons need 500t press, 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 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. 1774 3000t press, British 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 poster press, 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. Machine is the basic means of production and support of advanced manufacturing technology and equipment industry, equipment manufacturing industry is the basis of equipment, mainly for the automotive, military, agricultural machinery, construction machinery, electrical equipment, railway locomotives, ships and other service industries. For several years, China has become the world's largest machine tool consumer and importer of machine presses, is the world's third largest producer of machine tools. Machine classification: 1. Press precision can be divided into ordinary precision machine tools, precision machine tools, and high-precision machine tools. General machine tools: including lathes, drilling, boring, milling, planing, slotting and so on. Precision machine tools: including grinders, gear cutting machines, screw machine tools and other kinds of precision machine tools. Precision machine tools include: coordinate boring, gear grinding, thread grinding, high-precision hobbing machine, high-precision machine engraved lines and other high-precision machine tools. 2. Press the degree of automation can be divided manually operated machine tools, machine tools and semi-automatic machines. 3. Press the machine control, can be divided into copying machines, process control machine tools, CNC machine tools, adaptive control machine tools, machining centers and flexible manufacturing systems. 4. Press the scope of the machine can be divided into general, special tools. 5 .. according to the workpiece size and weight of the machine tools can be divided into the instrument, small tools, large machine tools, heavy and super heavy machine tools. 500t press, Chen Hua machinery (certified), presses supplied by China Machinery Co., Ltd.
