Hiwin HG Series Linear Rails

How to solve the noise caused by the slider on the straight guide rail during operation? Next, Ruijian will talk about how to solve the noise problem of linear guides in practical operation!

The principle of the rolling body on the slider moving back and forth in the track groove for cycling is that when the rolling body slides, it will produce some noise. How do we deal with this situation? What other methods are there to reduce this kind of noise? Perhaps it is due to excessive noise and abnormal operation, which can simply reduce the lifespan and accuracy of the equipment and increase its repair costs.

1. Different devices require different preloads, which will also result in noise levels;

The so-called preload refers to the preload force of the rolling body of the linear guide slider on the trajectory, also known as the fit degree

The preloading levels of linear guide slider are divided into light preloading, medium preloading, medium preloading, and overweight preloading. The selection criteria for different preloading methods are as follows:

Light preloading, suitable for equipment with fixed load direction, sensation, low impact force, and 2-axis parallel operation. Devices with low precision requirements and low sliding resistance per request. For example, beam welding machinery, binding machinery, active packaging machines, XY axes of typical industrial machinery, active door and window processing machines, welding machines, fuses, east-west exchange equipment, various material supply equipment, CNC engraving and milling machines, lightweight milling machines

Medium preloading: equipment with cantilever load or torque, equipment for single axis operation, equipment with light load and high precision requirements. For example, grinding machine worktable feed axis, active coating machine, industrial robot, NC lathe, electric discharge machining machine, measuring instrument, fine XY channel

Heavy preloading: Request equipment with high rigidity, strong impact force, and high load cutting machine tools. For example, machining bases, NC lathes, grinding wheel feed shafts for grinding machines, milling machines, vertical or horizontal boring machines, tool guides

Overweight preloading: requires high rigidity and strong shock force, such as the Z-axis of the operating machinery and the machinery suitable for heavy preloading

2. In professions with high dust levels, simply present the noise situation of linear guides;

In this situation, we can choose the Pi Ruijian slider with dust-proof equipment supplied by Ruijian Guide Company, or order the high-strength dust-proof equipment from Taiwan STAF represented by Ruijian. We can choose the linear guide slider according to our own practical needs.

3. Different smooth oils can also produce noise;

Some customers use high-strength grease due to the inconvenience of refueling the machine, which has a particularly high viscosity and increases the friction of the rolling body, resulting in increased noise. Perhaps some equipment manufacturers do not refuel diligently, causing the rolling body to be unsmooth and increasing noise, which can also reduce the service life of the equipment. We usually recommend customers to use Mobil 2 smooth grease, Ruijian linear guide special smooth grease, which has viscosity and its smoothing effect, and is composed of molecules that are suitable for various equipment.

4. Incorrect selection of equipment. Some devices have light loads, but many customers do not calculate their dynamic loads and feel that they should choose large loads instead of small ones. This results in light loads and large guide rails, which will definitely increase noise and overload the motor, leading to a shorter lifespan.
