ABSTRACT:
A spindle device of a machine tool such as a milling machine and a machining center and a method of replacing a spindle, the spindle device wherein the housing of a spindle head (5) is divided into a front housing (23) and a rear housing (25), a spindle (7) is installed in the front housing (23) through front bearings (9), and a built-in motor rotor (43), a bearing case (33) through rear bearings (11), and a draw bar (51) for clamping a tool are installed on and in the spindle (7) to form a front housing unit (93); the method comprising the step of replacing the spindle (7) and the bearings by replacing the front housing unit (93), whereby, when the spindle device comes out of order, the spindle and bearings can be easily replaced in a short time and the stop time of the machine tool can be minimized at a site where the machine tool is used.
