With the development of numerical control technology, surface grinder price, hydrostatic bearings are also widely used in machining centers, CNC machine tool spindle. YTO AG first engine plant, there are many static pressure and static pressure diamond grinder boring head, carried out some exploration and try to repair, made a few experiences. There's Orifice maintenance experience. 1. External to internal throttle throttle surface grinder, and the installation of the upper and lower chamber pressure gauges instantly displays. Make maintenance easy, in particular, can easily be cleaned regularly, this is an internal restrictor incomparable. 2. Throttle ratio. Throttle than the theoretical value of β is between 1.2 to 1.5, and 1.25 based on years of experience is preferred. Such maintenance, the need for precision spindle geometry before and after bearing geometric accuracy, concentricity, roundness and taper strictly controlled to ensure β values. Determine the value of e (eccentricity amount spindle and bearing geometric center) based on the carrying capacity of the machine, so that the optimum value of β. 3. The oil chamber when the spindle is not installed, the oil port of oil each column must be consistent (observation), if not, should be taken to change the way restrictor aperture surface grinder maintenance, changing its flow. In the cavity 4, for example, generally lower, left, and right chamber oil column between 20 ~ 25mm, hole diameter 0.25 ~ 0.4mm.

Grinder manufacturers, surface grinder manufacturers, cylindrical grinder manufacturers, surface grinder price, the price of second-hand grinder. China's machine tool industry in accordance with the practice of international M & A statistics December 14, 2009 to obtain: 2002 to 2008 annual foreign investment of Chinese enterprises grow from $ 2.7 billion to about $ 56 billion, an average annual growth rate reached 66%. Our overseas mergers and acquisitions remained active into 2009, along with the expansion of the international financial crisis, the global cross-border investment has shrunk dramatically, but from January to September 2009, foreign invested enterprises in China still reached about $ 33 billion, basic and 2008 year-ago quarter. At the end of 2003 to 2009 in the third quarter, China had 437 enterprises overseas M & A deals worth a total of $ 116.8 billion. International mergers and acquisitions China's machine tool industry since 2000, belongs to an early start in the industry surface grinder models considered in terms of the whole machinery industry pioneer. China's machine tool industry out from 2002 to 2008 between the country for international acquisitions completed a total of 13, including six in Germany, the United States 3, Japan 2, France 1, England 1. After the merger have reached the intended purpose, satisfactory operating results. It is understood that the machine tool industry now ongoing project also intends to overseas acquisitions, Germany, the United States each one. In fact, China's overseas M & A activity was not affected by the financial crisis, contrary to some powerful enterprises of international financial crisis as an opportunity for overseas acquisitions. Appropriate international mergers and acquisitions will not only improve the international competitiveness of Chinese enterprises in the level of product technology and operations management, and in the current international economic situation in a recession, if the operation is running properly, it may be take advantage of mutual complementarity and win-win of a viable way.
