The main factors that affect the quality of seamless steel tube machining are machine tools, knives, fixtures, workpiece blanks, process methods and processing environment. To improve the quality of
seamless steel tube cutting, we must take appropriate measures in these areas, such as reducing machine work error, the correct selection of cutting tools to improve the quality of blanks, reasonable arrangements for the process to improve environmental conditions.
Commonly used methods to reduce the cutting error of seamless machine tools are:
(1) enough precision and stiffness of the machine.
(2) if necessary, it is possible to use the revise method of screw grinder or hobbing machine to correct the error of the machine tool transmission system according to the previously measured machine chain error correction device.
3. Use the machine tool jig to ensure the machining precision, for example, using the drill die processing box on the drilling system, so that the precision of the drill die is not affected by the positioning error of the machine tool.
Prevent the thermal distortion of machine from affecting the accuracy of machining impact.
Eliminate vibration sources inside the machine and take vibration isolation measures to reduce the vibration and accuracy of seamless steel tube.
To improve the automation of machines, such as active measurement or automatic control system, to reduce the seamless process of human errors.
