A spring forming machine comprising a wire feeder, a forming tool, a cored bar, a pitch tool, and a cutting tool, wherein, in use, a wire is fed from the wire feeder along a horizontal wire feeding line and brought into contact with the forming tool so as to be formed into a coil spring surrounding the cored bar, the pitch tool being configured to expand a space between coils of the coil spring and to be inserted between the coils of the coil spring from one side in a vertical direction with respect to the coil spring, and the cutting tool being configured to separate the coil spring from a remaining wire and to approach and separate from the coil spring from an other side in the vertical direction with respect to the coil spring, the spring forming machine further comprising: a forming tool slide mechanism including a slider to which the forming tool is fixed, the slider being supported to be linearly movable in a direction inclined with respect to the wire feeding line; a first lifting mechanism including a slider to which the pitch tool is fixed, the slider being supported to be liftable on one side in the vertical direction with respect to the cored bar; a second lifting mechanism including a slider to which the cutting tool is fixed, the slider being supported to be liftable on an other side in the vertical direction with respect to the cored bar; a fixing base to which the wire feeder and the forming tool slide mechanism are attached; a lifting base that is liftably supported by the fixing base, and to which the cored bar, the first lifting mechanism, and the second lifting mechanism are attached; a plurality of servo motors that are drive sources of the wire feeder, the forming tool slide mechanism, the first lifting mechanism, the second lifting mechanism, and the lifting base; a controller that is configured to control the plurality of servo motors; an individual drive control unit that is provided in the controller and configured to individually drive each of the servo motors corresponding to an operation of an operation unit; and an interlocking control unit that is configured to, when the servo motor of the lifting base is individually operated, interlock the servo motors of the lifting base and the first lifting mechanism so that the slider of the first lifting mechanism is not lifted and lowered with respect to the fixing base by lifting and lowering of the lifting base with respect to the fixing base, and, when the servo motor of the first lifting mechanism is individually operated, not interlock the servo motors of the lifting base and the first lifting mechanism. a forming tool slide mechanism including a slider to which the forming tool is fixed, the slider being supported to be linearly movable in a direction inclined with respect to the wire feeding line; a first lifting mechanism including a slider to which the pitch tool is fixed, the slider being supported to be liftable on one side in the vertical direction with respect to the cored bar; a second lifting mechanism including a slider to which the cutting tool is fixed, the slider being supported to be liftable on an other side in the vertical direction with respect to the cored bar; a fixing base to which the wire feeder and the forming tool slide mechanism are attached; a lifting base that is liftably supported by the fixing base, and to which the cored bar, the first lifting mechanism, and the second lifting mechanism are attached; a plurality of servo motors that are drive sources of the wire feeder, the forming tool slide mechanism, the first lifting mechanism, the second lifting mechanism, and the lifting base; a controller that is configured to control the plurality of servo motors; an individual drive control unit that is provided in the controller and configured to individually drive each of the servo motors corresponding to an operation of an operation unit; and an interlocking control unit that is configured to, when the servo motor of the lifting base is individually operated, interlock the servo motors of the lifting base and the first lifting mechanism so that the slider of the first lifting mechanism is not lifted and lowered with respect to the fixing base by lifting and lowering of the lifting base with respect to the fixing base, and, when the servo motor of the first lifting mechanism is individually operated, not interlock the servo motors of the lifting base and the first lifting mechanism.
