Cooling measures for the screw during operation. The screw is one of the common product components in large machinery, and its importance has been increasingly recognized by more and more people. For example, personnel engaged in industrial mechanization also regard the screw as a sign that the machine can operate stably and normally. From this, it can be seen that its functionality is relatively strong, mainly manifested in the following industries: In the electronic machinery industry, many devices use screw rods, such as measuring instruments, which have high requirements for measurement accuracy In the field of machinery, its product range is very wide, because in the machinery industry, the machining requirements for each workpiece are very high. Whether it is milling machines, grinders, drilling machines, lathes, etc., as long as it is used, the accuracy error is generally below 0.1 millimeters In the field of CNC, the use of screw rods is also widespread. Many CNC mechanical equipment are large and can achieve automated machining and production, but this will not affect their machining accuracy at all; However, its use allows for free conversion between linear and reciprocating motion on CNC machining machinery, ensuring machining accuracy As is well known, during the operation of the screw, there will be some degree of temperature rise, and the shaft will elongate due to thermal expansion, resulting in positioning accuracy errors. Therefore, when strict positioning accuracy is required, corresponding cooling measures should be taken:
1、 Minimize the pre tension of the screw and bearing seat as much as possible while meeting the product requirements
2、 Choose a larger lead as much as possible to reduce the rotational speed
3、 Choosing the appropriate lubricant is important
4、 If possible, use lubricating oil or cold air to forcibly cool the screw shaft.
