Linear guide installation and force control in the form of machine axis common rail support are the following forms: 1, one end fixed - end free rail end fixed, other end free. Fixed end bearings withstand the axial and radial forces, which supported a small way for the trip short rail or closed loop of machine tools, linear guides for the North Sea, because of mechanical positioning accuracy of this structure is the most unreliable, especially for large aspect ratio rail (linear guide relatively slender), thermal denaturation is obvious, linear guide purchase, 1.5m long rails in hot and cold under different environmental change is normal 0.05 ~ 0.10mm . However, due to his simple structure, easy installation, a number of high-precision machine tools still used to this structure, but the grating must be installed using closed loop feedback. Design of the rail system, and strive to have the largest area of ??contact between the fixed element and a mobile element, linear guides sales, which will not only increase the carrying capacity of the system, and the system can withstand the impact of intermittent cutting or gravity cutting produced the extensive force diffusion, expand the area of ??endurance. To achieve this, the groove shape of the rail system are varied, there are two typical, linear guide production, to be called brother formula (pointed arch), is an extension of the semicircular shape, the contact point for the vertex; the other is rounded, the same can play the same role. Linear guide can be understood as a rolling guided by the ball rolling infinite loop between the slider with the rail, so that the load platform along the high-precision linear motion guides easily and the sliding friction coefficient down to the usual traditional guide fiftieth cited, can easily achieve high positioning accuracy.
