We present optical interferometric observations of two double-lined spectroscopic binaries, HD 6118 and HD 27483, taken with the Palomar Testbed Interferometer (PTI) in the K band. HD 6118 is one of the most eccentric spectroscopic binaries, and HD 27483 is a spectroscopic binary in the Hyades open cluster. The data collected with PTI in 2001-2002 allow us to determine astrometric orbits, which, when combined with the radial velocity measurements, determine all orbital parameters of the systems. The masses of the components are 2.65 ± 0.27 and 2.36 ± 0.24 M ☉ for HD 6118 and 1.38 ± 0.13 and 1.39 ± 0.13 M ☉ for HD 27483. The apparent semimajor axis of HD 27483 is only 1.2 mas, making it the closest binary successfully observed with an optical interferometer.
