Linear Cylindrical Guide A type of rolling guide in which rolling steel balls reciprocate infinitely between the slider and the guide rail. The load platform can easily move linearly with high precision along the track. Compared with the traditional machine tool guide rail, the friction coefficient of the rolling guide rail can be reduced to 1/50 of the original. Because the starting friction is greatly reduced, the occurrence of ineffective motion is relatively reduced, so high-precision feeding and positioning can be achieved. Therefore, it can cooperate with the ball screw and use the linear guide as the guide, which will greatly improve the accuracy and mechanical efficiency of the equipment. We often say that we need to do maintenance for linear cylindrical guides, so what is the role of linear cylindrical guide maintenance? Let's take a look together below!
1. Reduce wear and maintain high precision for a long time
Traditional sliding guide rails will inevitably cause poor platform movement due to oil film countercurrent, and insufficient lubrication during movement will cause wear on the contact surface of the running track, thereby affecting accuracy. The wear of the rolling guide is very small, so the equipment can maintain high precision for a long time.
2. Suitable for high-speed movement and greatly reduce the driving power required by the equipment
Because the friction force when the linear guide moves is very small, only a small amount of force is needed to make the load platform move, especially when the equipment working mode is regular reciprocating motion, it can significantly reduce the power loss of the equipment. And because the heat generated by friction is small, it is suitable for high-speed movement.
3. Easy to assemble and interchangeable
When assembling, it only needs to mill or grind the mounting surface of the guide rail on the machine tool, and fix the guide rail and the sliding block on the machine tool with specific torque according to the steps, which can reproduce the high precision during processing. Sliding the guide rail takes a lot of time, and when the precision of the guide rail is poor, it is necessary to reproduce flowers. The linear guide rails are interchangeable, and the guide rails or sliders or even the linear guide rail groups can be replaced separately, and the equipment can obtain high-precision guidance from the beginning.
