(www.qdchenhua.com) is specialized in the "press, ports bollard, adjustable multi-axis tapping drilling machine, CNC multi-axis drilling, milling goal" of the enterprise, the company adhering to the "integrity management , hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Yuan Xi Chuan. 1797, the British record Maudslay made by screw drive turret lathe, to achieve mobility and turning threaded drill feed prices, which is a major change in the structure of the machine. Maudslay has been called "the father of the British machine tool industry." 19th century, due to promote textile, power, transportation machinery and arms production of various types of machine bed CNC machine tools have appeared. In 1817, the British created the goal planer Roberts; 1818 American Whitney (his full name is Eli Whitney) made of horizontal milling machine; in 1876, the United States made universal cylindrical grinder; 1835 and 1897 years and has invented hobbing and slotting machine. Ancient Drilling Drilling - "Bow windlass" drilling technology has a long history. Archaeologists have now found that 4000 BC, humans have invented the punch with the device. The ancients shelves in two columns a beam, then hang a rotatable awl down from the crossbar, then wrapped with bow awl driven rotation, so you can punch a stone on wood. Soon drilling products, it is also devised called "gin" in drilling equipment, it is also the use of elastic bow, making awl rotation. The first drill (Whitworth, 1862) to 1850, the German 马蒂格诺尼 first made a twist for metal punch; 1862 in London, England on the International Exposition held drill, England Whitworth who exhibited powered by the drilling of cast iron cabinet, which became the prototype of the modern drilling. Later, various drilling spate of drilling supplies, there is radial drilling machine, drilling machine with automatic feed mechanism, and can play more than once at the same time, such as multi-axis drilling holes. Due to improvement of tools and materials, and drill, coupled with an electric motor, a large manufacturer of high-performance drilling has finally come out.
