Chinese name: CPC linear guide mbth: CPC linear guide properties: rolling guide features: less wear can maintain accuracy for a long time. Introduction, characteristics, working principle and introduction CPC is a kind of rolling guide rail. With the infinite rolling cycle between the slider and the slide rail with steel balls, the load platform can easily perform high-precision linear motion along the slide rail. In addition, the design of the binding unit between the slider and the slide rail enables the CPC linear guide rail to bear loads in all directions at the same time. The above display features are not comparable to those of the traditional sliding guide rail. Therefore, if the machine can cooperate with the ball screw and use the CPC linear guide as the guide, the equipment accuracy and mechanical efficiency will be greatly improved. Compared with the traditional sliding guide, the friction coefficient of rolling guide can be reduced to the original 1/50. Because the starting friction is greatly reduced and relatively few invalid motions occur, it can easily realize micron-level feeding and positioning. Features (1) The traditional sliding guide rail can keep the accuracy for a long time, which will inevitably lead to poor movement accuracy of the platform due to oil film countercurrent, and the contact surface of the running track will be worn due to insufficient lubrication during movement, which will seriously affect the accuracy. The wear of the rolling guide rail is very small, so the machine can keep the accuracy for a long time. (2) High positioning accuracy When the CPC linear guide rail is used as the linear guide rail, because the friction mode of the CPC linear guide rail is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide rail, but also the gap between dynamic friction and static friction becomes very small. Therefore, when the lathe bed is running, there will be no slippage, and the positioning accuracy of micron level can be achieved. (3) It is suitable for high-speed movement and greatly reduces the driving horsepower required by the machine. Because the friction of CPC linear guide rail is very small, the bed can be operated with less power, especially when the bed works in regular reciprocating motion, which can significantly reduce the power loss of the machine. And is suitable for high-speed operation. (4) It can bear loads in four directions: up, down, left and right. Because of the special binding structure design of CPC linear guide rail, it can bear the load in the up, down, left and right directions at the same time, unlike the sliding guide rail, which can bear the transverse load parallel to the contact surface direction, it is easy to cause poor machine running accuracy. (5) Simple lubrication structure If the sliding guide rail is not lubricated enough, the contact surface metal will directly rub and wear the lathe bed. However, it is not easy to get enough lubrication for the sliding guide rail, and it is necessary to drill holes in the proper position of the bed for oil supply. On the other hand, the CPC linear guide rail is equipped with a nozzle on the slider, which can directly inject grease with an oil gun, or can be replaced with a special oil pipe joint to connect the oil supply pipe for automatic lubrication. (6) Easy to assemble and exchange. When assembling, we only need to mill or grind the assembly surface of the slide rail on the lathe bed, and fix the slide rail and slide block on the lathe bed with specific torque according to the suggested steps, so that the high precision of machining can be reproduced. The traditional sliding guide needs to shovel the running track, which is laborious and time-consuming, and once the accuracy of the machine is poor, it must be shoveled again. CPC linear guide rails are interchangeable, and the slider or slide rail or even CPC linear guide rail group can be replaced separately, so that the machine can regain high-precision guidance. Working principle CPC linear guide rail can be understood as a kind of rolling guide rail. The steel ball rolls endlessly between the slider and the guide rail, and the friction coefficient is reduced to one fiftieth of that of the ordinary traditional sliding guide rail, so that the load platform can easily perform high-precision linear motion along the guide rail, and high positioning accuracy can be easily realized. The final unit design between the slider and the guide rail, patented reflux system and simplified structural design make the silver-plated CPC linear guide rail move more smoothly and with lower noise. So that the linear guide rail can bear loads in all directions at the same time. Working principle of CPC linear guide rail
