There are certainly a lot of friends want to know something about the history of boring, just as we want to understand some of the war, like the Warring States period, causing curious to explore. Hengda tell you: in the 15th century due to the need to manufacture weapons, had already seen a hydraulic-driven barrel boring. After the 1769 J. Watt steam engine made practical patents, precision cylinder steam engine became a key issue. 1774 British J. Wilkinson (also translated John Wilkinson) barrel boring invention, the following year for the Watt steam engine for the cylinder block machining. In 1776 he created a more accurate cylinder boring. Cylinder boring appear decades after 1880, began production in Germany with around columns and horizontal boring machine table. Updated to adapt to the era of large machining, especially heavy workpiece 1930s developed a boring machine. With time, the flow of work, milling increases the 1950s there has been landing boring and milling machine. Early 20th century, the development of watch manufacturing equipment, need to process smaller device pitch error rocker universal milling machine manufacturers in Switzerland appeared coordinate boring. In order to improve the positioning accuracy of boring machine has been widely used in optical reading head or digital display device. Some boring machine also uses digital control system for coordinate positioning and processing automation. Our lives change, the same thinking is changing rocker milling machine, boring now from a body, we can know that the trend is significant that the purchase horizontal boring machine, floor type boring and milling machine manufacturers, horizontal boring machine Manufacturers, boring manufacturers. Hengda CNC machine tools is your best partner for life. For the structural characteristics of horizontal boring and milling machine, Which plants can give my best to answer? Hengda NC tell you. Boring parts mainly coaxial holes in the box for a long hole boring represent cutting rocker milling machine, metal cutting is one of the most important content. So for a boring it's important proportional. But even though there are still using the boring mold, bushings, implementing a long hole boring instance column supporting long boring bar or manual alignment methods such as 180 ° rotation of the workpiece after milling and boring desktop. But in recent years, on the one hand due to the large number of CNC machining centers and milling and boring machine used to make all kinds of horizontal milling coordinate positioning accuracy and precision rotary indexing table has been greatly improved, the long hole boring gradually being efficient work Taiwan swing 180 ° U-turn boring self-positioning of the mass production and application of universal radial milling prices, rotary table 180 ° self-localization of a U-turn from the boring machine structure, almost boring in on this kind of machine long hole the only way. Similarly, the second-hand milling and boring machine is characterized by the same result, but the old and the new points only. Used milling and boring, boring machine manufacturers, vertical coordinate boring, boring machine manufacturers, Hengda NC, your most satisfying business cooperation.
