PROBLEM TO BE SOLVED: To provide an electric milling machine capable of obtaining a particle diameter of a milled powder similar to that in a traditional manual stone mill and making a device to a light weight and a small size as well as the stone mill to a light weight and a small size and economical for home by simplifying the whole mechanism. SOLUTION: The electric milling machine 1 is provided with: a first hand mill 3, which keeps an upper stone mill 31 and a lower stone mill 32 having a lower surface and an upper surface adjacent to each other coaxially arranged, the upper stone mill 31 non-rotatably fixed, and the lower stone mill 32 rotatably supported through a deceleration means 43 by a drive source 41; and a second mill 7 for rough milling provided between the upper stone mill 31 and a hopper 2. A rotation rough milling blade of the second mill 7 is driven coaxially to the lower stone mill 32. The second mill is provided with a means for adjusting a clearance between a fixed rough milling blade and the rotation rough milling blade. The means for adjusting the gap between the fixed rough milling blade and the rotation rough milling blade comprises a means for varying a vertical position of the fixed rough milling blade. Further, the first hand mill may be provided with a clearance adjustment mechanism 33 for adjusting a clearance between the upper stone mill 31 and the lower stone mill 32.
