What error will occur in the cutting of seamless carbon steel pipe machine tools?

The main factors affecting the processing quality of seamless steel tubes are machine tools, tools, fixtures, workpiece blanks, process methods and processing environments. In order to improve the cutting quality of seamless steel pipes, it is necessary to take appropriate measures in these aspects, such as reducing machine tool working errors, correct selection of tools to improve blank quality, rational arrangement of technological processes, and improvement of environmental conditions.

The methods commonly used to reduce the cutting error of seamless pipe machine tools are:

1. Use the machine with sufficient precision and rigidity.

2. Compensation and correction methods can be adopted when necessary, such as on thread grinders or gear hobbing machines, the error correction device of the machine tool chain error measured before is used to correct the error of the machine tool transmission system.

3. The machine tool fixture is used to ensure the machining accuracy. For example, the boring die is used on the hole system to process the box, so that the accuracy of the hole from the boring die is not affected by the positioning error of the machine tool.

4. Prevent the thermal deformation of the machine from affecting the machining accuracy.

5. Eliminate the vibration source in the machine and take vibration isolation measures to reduce the impact of vibration on the machining accuracy and roughness of seamless steel pipes.

6. Improve the automation degree of the machine, such as the use of active measurement or automatic control system to reduce the seamless processing process of human error.
