We have developed a new 6-axis apparatus in which movement of the six anvils are controlled by the high-tech servo mechanism. It is possible to keep the Kawai cell cubic within accuracy of ± 2 µm during compression and decompression. Pressures up to ca. 60 GPa have been generated by using sintered diamond cubic anvils with 14 mm edge length and 1.5 mm truncation. Comparison of the results with our previous experiments using the DIA-type press demonstrates that significant amount of applied load is lost by friction in squeezing the Kawai-cell by the DIA-type press. The load loss increases with increasing load, and it amounts to 45% of the applied load when compressed up to ca. 6.2 MN.
