Main factors affecting the quality of seamless steel tube
Machining is machine tools, tools, fixtures, workpiece blanks, processing methods and processing environment. In order to improve the cutting quality of seamless steel tube, corresponding measures must be taken in these aspects, such as reducing the working error of machine tools, selecting cutting tools correctly, improving the quality of billet, arranging process rationally and improving environmental conditions.


The common methods to reduce the cutting error of seamless machine tools are:
The machine has enough accuracy and stiffness when used.
(2) When necessary, compensation and correction methods can be adopted, such as in the screw grinder or hobbing machine, to correct the error of machine tool drive system according to the error correction device of machine tool chain measured previously.
(3) Use machine tool fixture to ensure the processing accuracy, such as using boring die box in the hole system, so that the accuracy of the drilling die is not affected by the positioning error of the machine tool.
(4) Prevent the influence of thermal deformation on the machining accuracy.
_Eliminate the vibration source inside the machine and take vibration isolation measures to reduce the vibration of seamless steel tube processing accuracy and roughness.
Improve the automation of the machine, such as the use of active measurement or automatic control system, to reduce human errors in seamless processing.
