How to choose high quality ball screw?

1.What are the commonly used types of ball screws, and what is the difference between rolled screws and ball screws? What are the common types of ball screws?High precision and accurate positioning are the main performance characteristics of ball screws, but if the mechanical production equipment can do these two points, it will basically require the model of the transmission element to be relatively complete. This kind of transmission components have a wide variety of characteristics, the production of more models, if there are more types, the adaptation to the demand environment is more extensive. The application of ball screws is more extensive, and in this wide use, there are several types are more used, the following will talk about the main application environment and characteristics of these types. 1. Ultra-high DN value This one is mainly used in some high-speed machine tools and high-speed comprehensive machining center machines. It is able to cope with complex situations in high-speed situations.

2, end cover type This type is mainly suitable for rapid handling systems, of course, some automated machinery also prefers this type.

3. High-speed This type of ball screw is mainly used in the production of some compact machinery, such as CNC machinery, precision machine tools, and high-speed machinery.

4. Precision grinding This type is mainly used in places with high precision requirements, such as the aerospace industry.

5. Rolling grade The advantages of this type of product are low friction, smooth operation, the important thing is that the price is not high, and the supply speed is fast.

The types of ball screw products are far more than the above, but they are used more, or if they are widely known, they may still be these types. Basically, these types of products are also widely adapted to many occasions. In addition to the above types, there are also nut rotary types and heavy-duty types, which are also used more.

The difference between cold rolled lead screw and ground lead screw is as follows:

Different processing methods Cold rolling wire rod is first cut a certain depth of groove on the rod material, groove spacing is equal to the length of the wire you want to process, and then roll out with a tooth rubbing machine similar to the processing of screw teeth.

On the basis of pressing and rolling, the grinding screw is precisely machined with a special cylindrical grinder for the circular groove of the same shape and size, and the cut groove is at the bottom of the circular groove.

Range of application and cost of different cold rolled lead screw accuracy grade medium lower, suitable for ordinary precision requirements are not high equipment. The use of the precision of the industry is not high, short life, efficiency, but the cost is low.

The precision level of the grinding lead screw is medium to high, which is suitable for CNC machine tools and other equipment with high precision requirements. It has high accuracy, long life, high efficiency, but also high cost.

The appearance of different cold rolled wire rod by extrusion molding, grinding level as the name suggests is the use of grinding processing. Rotary manufacturing and grinding process is different, naturally after the process traces. Cold rolled wire rod is generally smooth and shiny, with high glare under light conditions.

The grinding wheel grinding marks can be seen on the surface of the grinding screw carefully. In terms of appearance, the roller groove of the rotary screw rod is smooth and shallower than the grinding screw rod. There is usually a small groove at the top of the uplift between the roll groove and the roll groove of the rotary lead screw.
