AI Technical Summary

Technical Problem

The accuracy of the column of a horizontal boring and milling machining center changes after long-term use, affecting the machining stability and accuracy of the machine tool. Existing designs have failed to effectively improve the rigidity of the column and reduce its weight.

Method used

It adopts a hollow column design with symmetrical reinforcing walls and diagonal bracing inside. It uses HT300 high-strength gray cast iron material and combines the diagonal bracing structure of the motor base and tail end base to optimize the column structure to enhance rigidity and stability.

Benefits of technology

It improves the overall strength and torsional resistance of the column, reduces the processing difficulty, ensures the accuracy and stability during the processing, and optimizes the column structure.
