Some of our high-precision equipment will choose to install linear slides, because it can improve our efficiency and mechanical efficiency. Linear slides are often used on CNC machine tools. Since the friction method of linear slides is rolling friction, there is no slippage and high positioning accuracy. If you don't work in this area, you are still very unfamiliar with linear slides. Let me tell you what are the advantages of linear slides? Come and find out!
Linear slide
The first point, high positioning accuracy
When using the linear guide as the linear guide, since the friction method of the linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but the gap between the dynamic friction force and the static friction force is also small. Therefore, when the bed is running, there will be no linear slippage, and the positioning accuracy of um level can be achieved.
The second point, less wear can maintain accuracy for a long time
The traditional sliding guide will inevitably lead to poor motion accuracy of the platform due to the reverse flow of the oil film, and due to insufficient lubrication during motion, the contact surface of the running track will be worn, which will seriously affect the accuracy. The wear of the rolling guide is very small, so the machine can maintain the accuracy for a long time.
The third point is that it is suitable for high-speed movement and greatly reduces the driving horsepower required for the machine
Since the friction force of the linear slide rail is very small, only a small amount of power can be used to make the bed run, especially when the bed works in a regular reciprocating operation, it can significantly reduce the power consumption of the machine. And because the heat generated by friction is small, it can be suitable for high-speed operation.
The fourth point, can bear the load of up, down, left and right directions at the same time
Due to the special bundle structure design of the HIWIN linear slide rail, it can bear the loads in the upper, lower, left and right directions at the same time. Unlike the sliding guide, which can bear the lateral load in the direction of the parallel contact surface, it is easy to cause machine failure. Poor operating accuracy.
Fifth point, easy to assemble and interchangeable
When assembling, as long as the mounting surface of the slide rail on the table is milled or ground, and the slide rail and slider are fixed to the machine table with specific torque according to the recommended steps, the high precision during processing can be reproduced. In the traditional sliding guide, it is necessary to shovel the running track, which is time-consuming and labor-intensive, and once the precision of the machine is poor, it must be shoveled again. The linear slides are interchangeable, and the sliders or slides or even the linear slides can be replaced separately, and the machine can regain high-precision guidance.
Sixth point, the lubrication structure is simple
If the sliding guide is insufficiently lubricated, it will cause direct friction of the metal on the contact surface to wear the bed, and it is not easy for the sliding guide to be sufficiently lubricated, and it is necessary to supply oil at the appropriate position of the bed. The linear slide rail has a grease nozzle installed on the slide block, which can be directly injected with oil, or can be replaced with a special oil pipe joint to connect the oil supply pipe to lubricate with an automatic oil supply machine.
