PROBLEM TO BE SOLVED: To provide a small machining device capable of machining a spherical surface and a free curved surface at high precision. SOLUTION: A machining tank fitted with a work 12 is fixed to a work base 11, and the work base 11 is fixed to a D shaft rotated around the y-axis. A stay 2O holding the D shaft is fixed to a C shaft rotated around the x-axis, and a stay holding the C shaft is fixed to a Y shaft 9 linearly moved in the y-axis direction on an X shaft 8. The X shaft 8 is linearly moved in the x-axis direction on a base. A tool shaft 14 fitted with a machining tool 13 is held in a housing 18, and the housing 18 is fixed to a B shaft rotated around the y-axis. A stay 22 holding the B shaft is fixed to the A shaft rotated around the x-axis, and a stay 21 holding the A shaft is fixed to a Z shaft 10 linearly moved in the z-axis direction.
