A spindle assembly of a machine tool comprises a drive of main movement of a spindle located inside with possibility of transmission of torque by an electromagnetic field, a helical gear and a collet mandrel for a cutting tool or workpiece. A nut of helical gear from one side is connected to a rotor of an electromechanical system arranged coaxially to the spindle with possibility of rotation and creating a longitudinal field of different direction and from the other side through the rolling bodies - with an inlet plunger of small diameter, which is coaxially located in a fixed tapered distributing sleeve and generates fluid pressure in a closed hydraulic system acting on a coaxially located plunger of larger diameter to transmit force to a spring-loaded movable conic sleeve of a clamping chuck.
