Shank without expensive high-speed peripherals become able to achieve the dream of such a gripping way 3μ processing speed is different from traditional shank tooling systems. Simply pressing a tightening bolt, when tightening the bolt will push the piston seal block generates a hydraulic oil pressure in the holder, the pressure is transmitted uniformly to the steel from the circumferential direction of the expansion sleeve, the expansion wall and then toolholder tight. Using this tool clamping system, allows the system runout accuracy and repeatability of positioning precision control in 3μm or less. Because the handle memory in high-pressure fluid pressure, when the tool is clamped, the structure and the presence of high pressure oil chamber built oil greatly increases the structural damping, which can effectively prevent vibration of the tool and the machine spindle. Practical application shows that the use of this clamping system can not only improve the precision and quality, but also the life of the tool in machining has been doubled. With China's economic development speed shank installation, living standards improve speed shank design, the car as a consumer in people's lives become more prevalent. To seize the mainland market, affordable type of vehicle development and popularization of the major automobile manufacturers to increase market share as the only way to go. In this environment, to provide parts for the automotive manufacturers satellite manufacturers will have to reduce costs in order to reduce prices. The processing cost savings is the most effective and fastest way. In order to achieve cost-cutting by two methods: first, the high price of the original purchase, Germany and Japan to produce relatively low-cost tool, does not reduce the accuracy of the same grade tools. Second, to maintain the stability of the high-speed precision tool holders, long-term changes in the small high-speed precision machining shank sales, improve rough utilization while reducing tool wear and extend tool life. In order to work with the same level of precision of Germany and Japan, Poplar as a professional handle, tool manufacturers, after nearly two decades of effort, can achieve this high speed machining tool holders, Huizhou speed handle, Lu a CNC Precision Tool Unruh provided by the Dongguan City operation of a CNC precision tool. Dongguan City Unruh a CNC precision tool operators (www.luyidaoju.com) strong, credible, and other industries in Dongguan, Guangdong Mould accumulated large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu a CNC precision tool and you hand in hand into the brilliant, for a better future!
