TMT primary mirror consists of hexagon shape (1.44 m in diagonal diameter and 45 mm in thickness) segment mirrors. This article describes the fabrication process developed for these segment mirrors. Stressed mirror polishing (SMP) method is adopted taking the advantages of its process speed and attained smoothness in higher spatial frequency figure. Segment substrate bending fixtures enables versatile aspheric polishing of various types of TMT segments by adjusting the bending force distribution. Mass production of segment polishing has started and 22 segments were successfully polished to comply with the specifications. Detailed studies for hexagonal cutting and mounting of the polished mirror onto the segment support assembly to complete segment mirror assemblies are under way.
