Plastic guide rail for CNC machining lathe
by：QY Precision 2020-03-29
The plastic guide rail of the CNC machining lathe is a plastic soft belt with the same static and dynamic friction coefficients, wear resistance and vibration absorption on the sliding guide rail matching the bed guide rail, or plastic guide rails are made by injection molding between fixed and moving guide rails. This plastic guide rail has good friction characteristics, wear resistance and vibration absorption, so it is widely used in CNC machining lathes. The plastic soft belt is made of polytetrafluoroethylene as The Matrix, mixed and sintered with fillers such as bronze powder, molybdenum disulfide and graphite, and made into a soft belt. The domestic guide rail soft belt with the brand TSF is produced, and the supporting DJ adhesive. The process of using the guide rail soft belt is simple, as long as the guide rail paste surface is semi-finished to the surface roughness Ra1. 6 ~ 3. 2um, after cleaning the paste surface, glue it with adhesive, press and cure it, and then finish it. Because this kind of guide rail soft belt adopts the bonding method, it is habitually called'Plastic guide rail'. The material for guide rail injection molding is a two-component plastic with epoxy resin and molybdenum disulfide as The Matrix, plasticizer added, paste mixed as one component and curing agent as another component, and the domestic brand is HNT. The process of guide rail injection molding is simple. After adjusting the mutual position accuracy between the fixed guide rail and the moving guide rail, two-component plastic is injected. After curing, the fixed and moving guide rails are separated to form a plastic guide rail, the plastic guide rail made by this method is also called'Injection guide rail'.
