This study aims to examine a new Turcite-B Rails on structural dynamic characteristics of machine tool feed system effect of cutting stability. Ball linear guideway in use although there are advantages to reduce sliding friction, but for lack of machine vibration is more. This study used linear Rails modular concept, developed a new type of Turcite-B rail, in order to overcome the effects of traditional hard track to do difficult, too rely on the experience of human weakness. Turcite-B rail has a modular structure, use of their existing roller linear guideway dimensions as a standard, so that it can be quickly replaced his original roller slider without the need to make alternative processing. Slider interface affixed with a layer of Turcite-B wear-resistant liner, Turcite-B is a wear resistant resin, high wear resistance and can effectively reduce the frictional resistance and improve the system of machine vibration. For the assessment of TB Rails have a coercivity of effect, the research and application of finite element method for vibration analysis and vibration experiments do, through finite element analysis and evaluation of machine machining stability range (Stability Lobes), you can tell the speed and stability of relations between the maximum cutting depth, and then by cutting experiment to confirm cutting accuracy of stabilization diagram. After cutting experiments confirmed that the cutting experiment under different cutting depth and speed are in compliance with stability of cutting scope diagram, it can prove that TB-slider with a good vibration may improve the stability of feed mechanism when structure cutting.
