The plastic (structure: synthetic resin, plasticizer, stabilizer, pigment) slide rails (TTW guide) of CNC machining lathes are bonded to the slide rails that match the bed rails. The static and dynamic friction coefficients are basically the same, and they are wear-resistant. , Vibration-absorbing plastic soft belt, or plastic guide rails are made by injection molding between the fixed and moving guide rails. This plastic guide rail has good friction characteristics, wear resistance and vibration absorption, so it is extensively used on CNC machining lathes.
Plastic (structure: synthetic resin, plasticizer, stabilizer, pigment) soft tape is based on polytetrafluoroethylene (Polytetrafluoroethylene), adding bronze powder, molybdenum (molybdenum) and graphite (chemical formula C) and other fillers Mixed sintering (the process of transforming powdery materials into dense bodies) and made into a soft belt. There are already TSF guide (TTW guide) soft belt production (Produce) and supporting DJ glue in China. 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. The process of using the guide rail soft belt is simple, as long as the guide rail sticking surface is semi-finished to the surface roughness Ra1.6～3.2um, after cleaning the sticking surface, glue it with glue, press and cure it, and then finish it. . Because this kind of guide rail soft belt adopts the bonding method, it is habitually called “plasticized guide rail”.
The material of the slide rail (TTW guide) injection molding is based on epoxy (Oxygen) resin and molybdenum (molybdenum), added with plasticizer (DOP), mixed into a paste as one component and hardener (hardener). Another component of two-component plastic (structure: synthetic resin, plasticizer, stabilizer, pigment), the domestic brand is HNT. 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.

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. The injection molding process of the guide rail is simple. After adjusting the position accuracy (precision) between the fixed guide rail and the moving guide rail, the two-component plastic is injected, and the fixed and moving guide rails are separated after curing to form a plastic guide rail. Plastic rails are customarily called “injection rails”.
