Bearing the lathe bed of affirmatory horizontal lathe bed of appearance and dimension is sectional appearance basically depends on stiffness requirement, slideway position, the component that interior wants to install and platoon bits, the basic and sectional appearance of lathe bed sees figure below 1. The graph adds the configuration of clapboard between the rear wall before the 1a of figure of basic and sectional figure of 1 lathe bed is, use at medium or small lathe, stiffness is inferior. Graph 1b is double wall structure, stiffness is some taller than graph 1a. The lathe bed that graph 1c place shows is sectional appearance is the aperture that passes rear wall platoon bits, the body of such lathe bed but the box form that make it closes, stiffness is taller. Graph 1d basically is used at in, small-sized workbench does not rise fall type milling machine, double housing planer, the lathe bed of slotting machine and boring machine. To facilitate cooling fluid is mixed the flow of lubricating fluid, end face should have certain rake. Interior of graph 1e lathe bed can install the orgnaization with larger size, also can hold gasoline tank concurrently. Because of this kind of sectional lathe bed, clapboard join is not had between around wall, stiffness is inferior, often serve as the lathe bed that holds a machine tool gently, be like velar bed. Graph 1f is the lathe bed of heavy-duty machine tool, slideway can amount to 4-5. Pillar pillar but lathe bed of regard as vertical, its are sectional have a circle, square and rectangle, if pursue,2 are shown. Load of pillar place susceptive has two kinds: One kind is to bear curve load, the symmetrical face of load action Yu Lizhu, be like the pillar of vertical drilling machine; Another kind bears to bend and turn round load, be like milling machine, the pillar of boring machine. Graph the beam of basic and sectional appearance of 2 pillar and base beam are used on machine tool of frame of dragon door type, when making analysis getting power, can regard the Jian Zhiliang of two fulcrum, complex dimensional load bears when the job, because the stiffness of this beam is right impact of machine tool function is very big, its are sectional and general make it closes form. Base is the bearing with certain indispensable machine tool, because this must want,have enough stiffness. Graph the basic and sectional appearance of 3 beam CNC Milling
