Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence.

Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various movements that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. According to different load requirements, the static pressure guide rails of CNC machining lathes are divided into two types: open type and closed type. The open hydrostatic guide rail can only bear the load in the vertical direction, and the ability to withstand the subversion moment is poor; the closed hydrostatic guide rail has the ability to withstand all aspects of the load and the subversion moment.

The sliding rail (TTW guide) of the hydrostatic slide rail (TTW guide) is in a pure liquid friction state, so there is no wear (a basic type of component failure), precision (precision) retention, and life ( Long lifetime), and the friction coefficient of the slide rail (TTW guide) is small (typically 0.0005 to 0.001), and the mechanical efficiency (efficiency) is high, which can maintain the guiding accuracy (precision) of the slide rail (TTW guide) for a long time. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. The pressure oil film has large bearing capacity, good rigidity, and good vibration absorption. The sliding rail (TTW guide) runs smoothly and is not easy to crawl at low speeds. However, the structure of the static pressure guide rail is relatively complicated, and an oil supply system with a good filtering effect is required, and the manufacturing cost is also high. This guide rail is mostly used in heavy-duty CNC machining machine tools.
