The linear guide system is a kind of rolling guide. The steel ball makes an infinite rolling cycle between the slider and the guide rail, and the load platform can easily move linearly with high precision along the guide rail. Compared with the traditional sliding guide, the friction coefficient of the rolling guide can be reduced to 1/50 of the original. Since the friction force of the starting is greatly reduced, relatively few invalid movements occur, so the um-level feed and positioning can be easily achieved. Coupled with the bundle unit design between the slider and the guide rail, the linear guide can bear the load in all directions such as up, down, left and right at the same time. The above display characteristics are not comparable to the traditional sliding guide. Therefore, if the machine can be matched with a ball screw and used as a guide, the equipment accuracy and mechanical efficiency can be greatly improved.
When assembling, as long as the assembly surface of the slide rail on the machine table is milled or ground, and the slide rail and the slider are fixed on the machine table with a specific torque according to the recommended steps, the high precision during processing can be reproduced. The traditional sliding guide requires shoveling the running track, which is laborious and time-consuming, and once the accuracy of the machine is poor, it is necessary to shovel again. The linear slide rail is interchangeable, and the slider or slide rail or even the linear slide rail group can be replaced separately, and the machine can regain high-precision guidance.
When the linear guide moves, only a small amount of power is required to make the bed run, especially when the working mode of the bed is regular round-trip operation, which can significantly reduce the power loss of the machine. And because of the small heat generated by friction, it can be applied to high-speed operation. Due to the special bundle structure design of the linear guide, it can withstand the loads in the upper, lower, left and right directions at the same time, unlike the sliding guide, which can withstand lighter lateral loads in the direction of the parallel contact surface, it is easy to cause poor operation accuracy of the machine. If the sliding guide is not lubricated enough, it will cause direct friction loss of the contact surface metal. It is not easy for the sliding guide to be fully lubricated, and it is necessary to drill holes in the appropriate position of the bed to supply oil. The linear slide has an oil nozzle installed 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 to lubricate the automatic oil supply machine. In this way, the wear of the slider during the working process is greatly reduced, thus improving the service life. Our company has a large number of stock. Welcome to inquire.
