What is the guideway of NC machine tools? What are the classifications?
The guideway of a numerically controlled machine tool is the component that moves the moving parts of the work table, ram, and guides its movement, as the rails support the weight of the train and guide the way forward.Rail forms are sliding, rolling, hydraulic rail, etc..
The function of the slideway of machine tool is the function of guiding and supporting. Its precision, rigidity and structural form have direct influence on the machining accuracy and carrying capacity of machine tools. In order to ensure the machining accuracy of NC machine tools with high and large capacity, the guide rail with high precision, high stiffness, good abrasion resistance, good low-speed stability, and should try to make the guide rail has the advantages of simple structure, convenient manufacture, adjustment and maintenance. The commonly used guideways of CNC machines are divided into sliding guide and rolling guide according to their frictional properties.
