Each spindle is fixed on

respective base surfaces 12-15 of the caliper 16, which consists of two carriages 17 and 18 and two surface plates 19 and 20. Carriages 17 and 18 or surface plates 19 and 20, or other units 21, are attached to carriages 17 and 18, made, for example, in the form of ball wedges with

return paths, vertical linear guides 22 mounted on a rack 23. Through the vertical groove 2k of a rack 23, carriages 1-7 and 18 arrive, and outside the rack 23 cover overlay plates 19 and 20.

The rack 23 is fixed on the axial stopper 25 with the possibility of rotation together with it relative to the vertical axis of the VM from the electric motor 26 through the gearbox 27.

The tool assembly 2, consisting of a block of functional spindles 3, 6, a support 16, a stand 23 and a sub plate 25, is mounted on a cross slide 23 having the possibility of coordinate movement along the guides 29 and 30 relative to the frame 1 from the screw 31.

On the longitudinal guides 32 and 33 of the bed 1, a longitudinal table 3 is mounted, connected via a screw 35 to an electric motor 36. On a longitudinal table 34, a pivoting / separating table 37 is mounted, carrying satellite 38 with the workpiece 39, the envelope of which is shown in the drawing as cross shaded square. The rotation-dividing table 37 is connected via gear 40 to an electric motor 41 in order to rotate about the coordinate axis of the aircraft,

The functional spindles 3-6 are block-modular in design and equipped with independent sets of drives and control and control equipment: grinding spindle 3 is equipped with a drive 42 for rotating the grinding wheel 7, a drive for automatic movement as the wheel 7 of the coolant nozzle 43 is worn (not shown), a set of hydropneumatic equipment 44 and underwater communications links of hydropneumatic 45 and electrics 46 with junction boxes 47 and 48 mounted on a support 16

and the same for all functional spindles. The universal spindle C is equipped with a drive 49 for rotating the grinding wheel 8 and drives 50 and 51, respectively, for rotation relative to the coordinate axes K and SU, a set of hydropneumatic equipment 52 and communication links 45 and 46, with boxes 47 and 48. Coordinate grinding spindle 5 is equipped with rotational drive S3 grinding wheel E, radial flow 5, planetary motion 55 and rotation 56 relative to the coordinate axis of the SC, set of hydropneumatic equipment 57 and communication links 45 and 46 with boxes 47 and 48 .. Measuring spindle 6 is equipped with a drive 58 for turning relative to the coordinate axis of the SC, a set of hydro pneumatic equipment 59 and communication links 45 and 46 with boxes 47 and 48.

Each working spindle is equipped with an individual tool storage device 60-62, respectively, and installed next to the machine in front of its own spindle. On each accumulator 60-62, tool shops 63–65 are mounted movably in the direction of the machine, respectively, with tools 7–9. Shops are of disk type with the possibility of angular positioning from electric motors, 66–68, respectively.

The caliper 16 with respect to the column 23 is moved by means of a screw 69 from the electric motor 70, hydraulic cylinders 71 are provided for balancing the mass of the caliper with mounted spindles 3-6.

The machine works as follows.

In the initial position, the machined part 39 is mounted on the satellite 38 of the rotary-dividing table 37. The longitudinal table 34 is in the leftmost position, the support 16 of the tool unit 2 is in the extreme upper position, the slide 28 is in the extreme rear position, and the tool unit 2 is rotated to a position in which the working spindles are opposite their accumulators 60-62, respectively,

and measuring spindle 6 - in the working area of the machine. The working spindles 4 and 5 are rotated to a position in which the axes of rotation of the grinding wheels 8 and 9 are vertical, and the measuring probe 11 of the contact sensor 10 of the measuring spindle 6 is also located vertically. Tools are installed in the nests of the shops of drives 60-62.

Before machining the part 39, the tools 7 7 9 are changed in three working spindles x 3-5 at the same time or in one or two of them according to the control program, depending on the part 39 machining process. With a one-time change, the magazine 63 of the accumulator 60 moves sideways to the machine by the stroke, the caliper 16 rotates the electric motor 70 by means of the screw 69 and is lowered to its lower position, and the grinding wheel 7 of the grinding spindle 3 is fixed in the free slot of the magazine 63 of the accumulator 60, then the stores 64 and 65 simultaneously move to the machine by the stroke and fix the tools 8 and 9 of spindles 4 and 5 in free slots, then the grinding wheels 7-9 are simultaneously unclenched in spindle x 3-5, the store 63 of drive 60 moves to its original position ( from the machine) and takes out from the spindle 3 the grinding wheel 7, the support 16 rises to the upper position, with the straightened

0 grinding wheels 8 and 9 remain in the slots of magazines 64 and 65. Disk stores 63 to 65 rotate each angle corresponding to the next tool from the electric motor 66 - 68, respectively, the support 16 is lowered to the lower position, and new grinding wheels 8 and 9 are inserted in the nests of spindles 4 and 5, and upon subsequent movement of the magazine

on 63 drive 60 new circle 7

the spindle 3 is also inserted into the socket, then all three circles are clamped in their spindles, after which the magazines 64 and 65 of the accumulators 61 and 62 move to their original position (from the machine), the slide 16 rises to the upper position, and the store 63 of the accumulator 60 also moves to its original position (from the machine).
