The static pressure slide rail (TTW guide) of the CNC machining lathe is to transfer the oil with a certain pressure to the oil chamber between the sliding surfaces of the slide rail (TTW guide) through a throttle to form a pressure oil film to float the moving parts , The surface of the slide rail (TTW guide) is in a state of pure liquid friction. CNC machining generally CNC machining usually refers to computer digitally controlled precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

The feed route for finishing is basically carried out along the contour of its parts. Therefore, the work of determining the feed route is to determine the feed route for rough machining and empty stroke. In numerical control processing, the control system sends out instructions to make the cutter perform various movements that meet the requirements, and expresses the processing of technical requirements and processing requirements such as the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of processing parts on CNC machine tools. In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have also been developed and used in the aerospace industry. According to different bearing requirements, the static pressure guide rails of CNC machining lathes are divided into two types: open and closed. The open type static pressure guide rail can only bear the vertical load, and the ability to withstand the subversive moment is poor; the closed type static pressure guide rail has the ability to withstand various loads and subversive moments.

The TTW guide surface of the static pressure slide rail (TTW guide) is in a state of pure liquid friction, so it does not produce wear (a basic type of component failure), the accuracy (precision) is maintained well, and the life ( The lifetime is long, and the friction coefficient of the guide rail (TTW guide) is small (generally 0.0005 to 0.001), the mechanical efficiency is high, and the guide accuracy (accuracy) of the guide rail (TTW guide) can be maintained for a long time. CNC machining generally CNC machining usually refers to computer digitally controlled precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

The feed route for finishing is basically carried out along the contour of its parts. Therefore, the work of determining the feed route is to determine the feed route for rough machining and empty stroke. The pressure oil film has a large load-bearing capacity, good rigidity, and good vibration absorption. The TTW guide runs smoothly and is not prone to crawling at low speed. However, the structure of the static pressure guide rail is relatively complicated, and an oil supply system with good filtering effect is required, and the manufacturing cost is also high. This guide rail is mostly used in heavy-duty CNC machine tools.
