Introduce several cooling measures of ball screw in operation

The Ball Screw is one of the common product components of large Machinery, and its importance has been well known by more and more people. For example, those engaged in industrial mechanization also regard the ball screw as a sign of the stable and normal operation of the machine. . It can be seen that its functionality is relatively strong, mainly in the following industries:

In the electronic machinery industry, there are many devices that use ball screws, such as measuring instruments, which require high measurement accuracy.

In the field of machinery, it has a wide range of products, because in the machinery industry, machinery has high requirements for the processing of each processed part, whether it is a milling machine, a grinding machine, a drilling machine, a lathe, etc., as long as it is used, the accuracy is The error is generally below 0.1 mm.
In the field of numerical control, the use of ball screws is also very wide. Many CNC machinery and equipment are large-scale. They can realize automatic processing and production, but this will not affect its processing accuracy. However, its use can make CNC processing machinery The above Linear Motion and reciprocating motion can be freely converted, and the machining accuracy is also guaranteed.
As we all know, in the process of running the ball screw, the temperature will rise to some extent, and the shaft will be elongated due to thermal expansion, which will cause positioning accuracy errors. Therefore, when the positioning accuracy is strictly required, corresponding cooling measures should be taken:
1. On the premise of meeting product requirements, minimize the pre-tightening of the ball screw and Bearing seat;
2. Choose as large a lead as possible to reduce the speed;
3. It is very important to choose the right lubricant;
4. If possible, use lubricating oil or cold air to forcibly cool the screw shaft.
