Plastic guide rail for CNC machining lathe
Dec 10, 2018

The plastic guide rail of the CNC machining lathe is made by bonding the static and dynamic friction coefficient on the sliding guide rail matched with the bed rail, and the plastic soft belt with wear resistance and vibration absorption is made by injection molding between the fixed and movable guide rails. Plastic rails. This plastic guide rail has good friction characteristics, wear resistance and vibration absorption, so it is widely used on CNC lathes.


The plastic soft belt is made of polytetrafluoroethylene as a matrix. It is mixed with bronze powder, molybdenum disulfide and graphite to form a soft band. It has been produced in the domestic grade TSW soft belt, and the supporting DJ. Glue. The process of using the soft belt of the guide rail is simple, as long as the surface of the guide rail is semi-finished to a surface roughness of Ra1.6-3.2um. After cleaning the adhesive surface, it is bonded with glue, cured by pressure, and then finished by finishing. . Since such a rail soft belt adopts a bonding method, it is customarily called a "plastic rail".


The material for injection molding of the guide rail is a two-component plastic with epoxy resin and molybdenum disulfide as the matrix, plasticizer added, and mixed into a paste and a curing agent as another component. The domestic grade is HNT. The process of injection molding of the guide rail is simple. After adjusting the positional accuracy between the fixed guide rail and the moving guide rail, the two-component plastic is injected. After solidification, the fixed and movable guide rails are separated into a plastic guide rail. The plastic guide rail produced by this method is also known as a plastic guide rail. "Injection rails".
