How to prevent dust on linear guide rail and how to solve the problem of dust blocking slider?

Dust prevention is the most important part when using linear guide rail system. If dust and other foreign matter enter the back of the linear guide rail, it will cause abnormal wear and shorten the service life. Therefore, it is necessary to choose a sealing device or a dustproof device that meets the requirements of the use environment when dust and other foreign objects are expected to invade.

(1) Special sealing gasket for linear motion system In order to improve the dustproof ability, sealing gaskets made of special synthetic rubber with high wear resistance, as well as accessories such as (laminated contact scraper, etc.) and cleaning rings are provided in each linear guide rail system.

(2) Special telescopic dust cover In places where the use environment is harsh, some models are equipped with special soft retractable dust cover and special dust cover.

Please refer to the corresponding optional accessories (dust-proof) items of various products for details and descriptions of sealing gasket markings. In addition, when it needs to be used in an environment that is easily affected by cutting chips and cutting fluid splashing, it is suggested to use a soft circular telescopic cover to protect the whole system, or use a large telescopic dust cover. When the product is used, the dust will block the installation hole. What method can be used to remove it? Foreign matter may enter the slider after blocking the installation hole. In this case, we suggest installing an internal sealing gasket on the slider. In this way, the entry of foreign bodies and the erosion of water can be well prevented. For some models, it can be installed from bottom to top, so that there is no installation hole on the upper surface of the guide rail.

difference-between-screw-pitch-and-lead

What is the difference between screw pitch and lead?

26/09/2022/in Product News/by aresmotion

Pitch

Pitch is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.

Lead

Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified.

For a single start thread, lead is equal to the pitch. For multiple start screws the lead is the pitch multiplied by the number of starts.

rolled and ground ballscrews

What are the differences between rolled and ground ballscrews?

04/07/2022/in Product News/by aresmotion

The difference between cold rolling screw (rolled screw) and grinding screw is as follows:
1. Different processing methods:
Cold-rolled ball screw is to cut grooves with a certain depth in polished rod material at first, and the groove spacing is equal to the wire spacing you want to process, and then roll them out with a rolling mill. On the basis of press rolling, the grinding screw uses a special cylindrical grinder to precisely process the arc groove with the same shape and size, and the cut groove is at the bottom of the arc groove.

Rolled ball screw is preferred over cutting (turning on a lathe) for lead screws. It involves pressing a round bar between a set of dies that roll the threads into it. It results in a harder surface with superior surface finish for lead screws. Rolled ball screw is also the most common process for ballscrews because it is more economical and sufficiently accurate for most industrial applications. Lead accuracy can be held to better than .003 inch/foot and longer lengths are possible than with ground ballscrews.

If higher accuracy is required, grinding should be considered. The grinding process can hold lead accuracy’s as tight as .0003 inch/foot or better. However, this process is much more expensive and the maximum length of screw is much shorter.

2. Different scope of application and cost:
The precision grade of rolling screw is below the average, which is suitable for ordinary equipment with low precision requirements. It has a short life, high efficiency and low cost. The precision grade of grinding screw is above average, which is suitable for CNC machine tools and other equipment with high precision requirements. It has high precision, long life and high efficiency, but the cost is also high.
3. Different appearance:
The cold-rolled screw rod is formed by extrusion, and the grinding grade is processed by grinding. Turning is not the same as grinding process, and naturally there are process marks after it comes out. Generally, the surface of cold-rolled screw rod is smooth and shiny, and the light reflection rate is high and dazzling. Grinding marks of grinding wheel can be seen carefully on the surface of grinding screw. In terms of appearance, the raceway groove of the turning grade screw rod is smooth, which is shallower than that of the grinding screw rod.

ball screws ball nuts

What may cause premature failure of ball screws or ball nuts?

30/06/2022/in Product News/by aresmotion

In the working operation, the ball screw will always produce some friction. Under the appearance of these friction forces, the ball screw will wear to a certain extent. When the ball screw is used for a certain time, the ball screw will be damaged. This is the process of ball screw damage, but besides, there are other reasons that will cause ball screw damage, such as unreasonable use of staff. What are the reasons for ball screw damage?

1. The clearance of the ball screw guide rail is not appropriate.

When we install the ball screw, if the installation is not in place, the ball screw clearance may be too large. If this happens, when the ball screw is working, it will be easy to have a big impact. Under the influence of this situation, the wear speed of the ball screw will be greatly accelerated. If we want to solve this problem, we need to disassemble the ball screw and install it correctly.

2. Causes of lubrication

Before the ball screw is used, we need to lubricate it. At this time, some inexperienced novice employees may not be able to grasp the usage of lubricating oil. If the lubricating oil used by the novice ball screw is not enough, in this case, the ball screw will generate more friction when it is used, which will also have adverse effects on the ball screw. Therefore, at this time, the novice should add more lubricating oil to the ball screw for lubrication.

3.Excessive speed

Exceeding the ball nut critical speed can lead to pickup fingers breaking, which will allow to the ball bearings to come out of the nut. Exceeding the screw critical speed will cause the screw to whip or vibrate and cause misalignment. Shaft speeds resulting in screw surface speeds above 8,000 inches per minute will reduce rated life.
