The linear guide has been equipped with an oil nozzle on the slider, which can be directly injected into the grease with an oil injection gun, or it can be replaced with a special YouTube connector to connect the oil supply YouTube, so that the active oil supply machine is smooth. The fixed components are usually guide rails, which ensure the accuracy of the linear guide. If the linear guide is bent and deformed, the components will lose their fine guidance. The linear guide is interchangeable. The machine tool guide slider can be replaced by the slider or guide or even the linear guide group, and the machine can regain high-precision guidance.
Linear guide rail, also known as rolling linear guide rail pair, slide rail, linear guide rail, linear slide rail, rolling guide rail, is used for linear reciprocating motion places with high degree of parallelism. The rated load is higher than that of linear bearings, and there is a certain torque. High load can still be high-precision linear motion. Linear motion guide rails can be divided into sliding friction guide rails, rolling friction guide rails, elastic friction guide rails, fluid friction guide rails and other varieties, and are generally used in high-precision control numerical machine tools. Line rails are the use of rollers (double rows) to slide in the side chute of the guide rail, which belongs to the rolling guide pair.
The structure of the hydrostatic guide itself is relatively complex, and there is a set of oil supply system. A certain amount of guide oil is injected into the messy contact surface and forms a bearing oil film, so that the movement between the guide rail and the slider is in a state of pure liquid friction. This requires a high level of cleanliness of the smooth oil.
