    In a spindle control system in which a pulse coder is coupled with a spindle; a pulse train signal, derived from the pulse coder upon each rotation of the spindle through a predetermined rotational angle, is converted into an analog signal corresponding to the actual rotational speed of the spindle; and the analog signal is compared with a commanded speed signal to drive the spindle at the commanded speed. Upon application of a command for stopping the spindle at a predetermined position, a predetermined numerical value is set in an error register in accordance with a specified position signal from the pulse coder, the pulse train signal from the pulse coder is fed back to the error register, and the rotational position of the spindle is controlled with a signal corresponding to the content of the error register.

    engages with the upper end portion of the pull rod 13 located in the hollow part of the spindle. As the pull 13 is pulled by the concave spring 14 to the left, the cutter II is fixed on the spindle .4 in the position shown in FIG. 1. Thus, when the motor spindle is turned, the cutter 11 is activated. On the left end section of the spindle 4, a synchronous pulley 15 is installed to control the rotational speed of the spindle 4 and leave it S at a certain position, the pulley being connected using synchronous belts 16 and 17 to the pulse sensor 18 of the speed and position of the spindle. - - -,., - A slotted disk 19 is used as a pulse speed sensor and the position of the spindle, with the disk having many slots 20 converted in a channel on one disk diameter at predetermined intervals and one slot 21 in the channel on a different diameter. Opposite to the source of light 22, there are two phytoelements 23. and 24, in front of which a disk 19c of the hole is located, 5My.L. -, 95P.e. is part of a pulse speed sensor, it generates a signal as a sequence of pulses when spindle 4 is rotated one turn. The photocell 24 is an integral part of a pulse position sensor of spindle 4, it creates a single pulse corresponding to iipe to the Fissile angular position at turning the spindle by one turn. FIG. 1 is shown in advance. but the spindle position where it stops. In order to remove the tool 11 with the spindle 4, the element 25 provided with a groove M1 for supporting the tool in the tool storage 26 moves perpendicular to the tool holder 10 for engagement with the tool holder's circular groove 27. Then the headstock 1 is moved to the left by a feed drive consisting of an engine 28 and a running ax 29, by means of which the crank lever 30 turns clockwise around the shaft with a flat cam 31, overcoming the force of the springs 32 and pushing the left end of the rod 13 towards the spindle to the right, as a result of this, the tension pin 12 of the tool holder 10 is released from the stopper by means of the rod 13, and the cutter 11 and the tool holder 10 are placed into. magazine 26 and spindle 4 separate from tool holder 10 move to the left. The cutter 11 is fixed to prevent it from turning in the m gaszine 26, moreover, if the cutter 11 is subsequently used, after the spindle 4 stops at a certain angular position of rotation, the headstock 1 moves to the right to engage the spindle 4 with the tool holder 10, and the tension pin 12 is locked by thrust 13. As a result, cutter 11 and spindle 4 are always interlinked at the same angular ratio. To cool the spindle 4, there is a conduit 33, radiator plates 34 and a fan motor 35 for cooling. The spindle control system contains a speed master, formed by a register 36 (FIG. 2) and a digital-to-analog converter 37, a spindle position control unit 38 with a digital setting device, a switch 39 through which the signal from the speed setting device enters the comparison unit 40, to the second input of which through a digital-analogue Converter 41 provides a signal from a pulse speed sensor. The rotation speed of the spindle is controlled by the block 42. The signal to stop the spindle is supplied from the frame tape or the manual switch 43. Through the switch 44 it is fed to the comparison unit 40 at a given low-speed voltage, and through the switch 45 connects the comparison output 40 to the comparison unit 40. -h. In the case of controlling the rotational speed of the spindle 4, the set speed is written to the software tape, the value of this speed is stored in register 36 and converted by the digital-to-analog converter 37 of the speed setter to-analog voltage. On the other hand, control unit 38 creates control-. The control signal is only .dl. turning on the switch 39 through which a predetermined voltage is applied to one input terminal of the comparison unit 40. The signal of the speed sensor 18 is connected by a motor 7 spindle 4 ,. converted by a digital-to-analog converter 41 to an analog voltage proportional to the speed of the motor. This voltage is applied to the other input terminal of the comparison unit 40. The unit 40 compares the applied directions and controls the phase of the start signal of the speed control unit 42 so as to equate this speed of the spindle motor to a predetermined speed. When a signal is sent to stop the engine at a certain position from the program tape or the manual switch 43, the control unit 38 switches on the switch 44 and turns off the switch 39dl to provide a low-speed setpoint voltage isa of the comparison unit 40 and convert the engine 7 to a rotation with this speed. After that, at the time of the first signal on the pulse position sensor 18, the control unit 38 turns off the switch, 44 and turns on the switch 45, simultaneously entering into the adder 46 a predetermined value of the spindle angle relative to the position corresponding to the appearance of a pulse in the digital code. The signal from the pulse speed sensor is fed to the input of the adder 46 and through the switch 45 to the input of the comparison unit 40 switches the voltage proportional to the difference between the value specified in the digital code and the value, equal to the number of pulses coming from the pulse speed sensor.
    From the comparison unit, the signal will be sent to the speed control unit 42 until the number of pulses arriving at the adder 46 is equal to the specified one, which corresponds to the spindle stop in a certain position.
    Thus, the spindle motor 7, the pulse sensors 18, the total 46, the comparison block 40, the speed control block 42 and the digital-to-analog converter ± spruce 41 are
    contour of the spindle position control system 4.
