    The purpose of the invention is to increase the quality and accuracy of manufacturing while expanding the range of workpieces.
    FIG. I shows a machine with a mutual arrangement of working parts, top view; in fig. 2 is a longitudinal section of the machine through the non-elongated headstock, internal grinding and integrated unit and mechanisms for their movement; in fig. 3 is a diagram of a parallel arrangement of the axes of the workpiece and a 1pp for section of internal grinding; in fig. 4 is a layout diagram for internal grinding of iodine with an angle relative to the axis of the workpiece; in fig. 5 is a schematic of the axial orientation of the workpiece; in fig. 6 shows a grinding scheme for multistage surfaces; on f | n. 7 is a schematic diagram of a schlie turning mechanism 26 for straightening a circle. On the slide 29 for external grinding there is a mechanism for axial orientation 32 of the machined part 11, and on the headstock 8 at the level of the axis of the workpiece 11 there is a cantilever wheel straightening mechanism 12. A new hydraulic drive cylinder 6 and two hydraulic lock cylinders 7 are installed on the Novorot nlit 5. 1 Cp f-ly. 10 il.
    fowaning internal multistage surfaces; in fig. 8 shows the grinding scheme for the internal conic top; in fig. 9 is a grinding pattern for the outer conical surface; in fig. 10 is a sharpening scheme for grinding wheels for external and internal grinding.
    The first longitudinal slide 2 and the second longitudinal slide 3 are mounted on the longitudinal tracks yushi to the housing 1 with the possibility of longitudinal movement on the housing 1 using the first 4a and 46 second longitudinal feed mechanisms of the same design.
    On the first longitudinal slide 2, a Novorot plate 5 is installed with the possibility of turning to an angle when grinding the outer and inner conical surfaces with the help of a driven hydraulic cylinder 6. Fixed fixing and release of the rotary plate 5 to the longitudinal slide 2 are carried out using two locking hydraulic cylinders 7.
    On the swivel plate 5, the headstock 8 is rigidly fixed with a spindle 9 installed in it with a clamping chuck 10 in which the workpiece 11 is attached. On the headstock 8 at the level of the axis of the workpiece 11 a cantilever mechanism 12 is fixed for dressing the periphery and end of the outer grinding wheel 13 On the transverse guides, made on the longitudinal slide 3, there is a cross slide 14, set in motion by the cross feed mechanism 15 of the internal grinding wheel.
    A spindle assembly 16 with a spindle 17 for internal grinding is mounted on the cross slide 14. The spindle 17 for internal grinding can be installed parallel to the axis of the workpiece 11 (Fig. 3) or at an angle (X (Fig. 4). On the side surface of the longitudinal slide 3
    A housing is attached to a linear measuring system 18 for measuring the movement of the cross slide 14, to which the slider 19 is rigidly attached.
    A hydraulic cylinder 20 supplying and discharging the casing 21 of the inner grinding wheel 22 is rigidly mounted on the cross slide 14. On the longitudinal guides of the housing there is a rigid protective shield 23 passing through the cavities formed by the longitudinal slide 2 and 3. On the upper surface of the protective shield are active control during internal grinding 24 and during external grinding 25, as well as a turning mechanism 26 for dressing the face and periphery of the internal grinding wheel 22.
    A stand 27 is rigidly attached to the rear of the housing, on the upper surface of which is placed perpendicular or at an angle of 60 ° relative to the axis of the workpiece 11, transverse guides 28 with a support 29 for external grinding, moved by means of a cross feed mechanism of the external grinding wheel 30. In the front part the slide 29 has a spindle assembly 31 for external grinding and a mechanism for axial orientation 32 of the workpiece 11.
    The spindle assembly 31 can be mounted to the caliper 29 for external grinding in two positions, perpendicularly or at an angle of 15-20 ° relative to the transverse rails 28. The arrangement of the spindle assembly 31 at an angle of 15-20 ° takes place with the perpendicular position of the transverse guides 28 with respect to the axis of the workpiece 11 to ensure simultaneous external grinding of its face and cylindrical surfaces.
    The digital software system 33 and the electrical cabinet 34 are fixed to the housing 1 on the side of the headstock. The straight position of the rotary plate 5 (for grinding cylindrical surfaces) is fixed by the rear adjustable stop 35, and the rotated position (for grinding conical surfaces) by the front adjustable stop 36
    The machine works as follows.
    At the beginning, an automatic axial orientation of the workpiece 11 is carried out, the mechanism for axial orientation 32 occupies a working position at the level of the axis of the workpiece 11. The support 29 for external grinding moves along the X axis. To the workpiece 11 until the probe for an axial orientation 32 is reached programmable size A, corresponding to the end surface (Fig. 5). Longitudinal slide
    2, which were in the final left position, to move the new workpiece 11 to the right, move along the Z axis., Until a touch signal is received from
    axial orientation mechanism 32.
    The grinding of the outer cylindrical and end surfaces of the workpiece 11 (Fig. 6) is carried out by the outer grinding wheel 13 with the transverse movement of the slide 29 for external grinding along the X axis, and the movement of the longitudinal slide 2 along the Z axis. During the outer grinding the inner grinding wheel 22 is in the final right position.
    Grinding of internal cylindrical
    and the end surfaces of the workpiece 11 (Fig. 7) can be implemented in two ways: in the first case, the movement along the Z axis of the longitudinal slide 3 serves only to feed the internal grinding wheel 22 to the working position, straightening and oscillation during mortise internal grinding, internal grinding is carried out by the internal grinding wheel 22 when the cross slide 14 moves along the X axis and the longitudinal slide 2 along the Z axis.,; in the second case, grinding is performed by moving the longitudinal slide 3 and feeding the cross slide 14 after the longitudinal slide 2 has previously moved the workpiece 11 to the working position. In both cases, the outer grinding wheel 13 is in the rear end position.
    Grinding of the internal and external conic surfaces of the processed
    Details 11 is carried out automatically within the framework of the operating cycle after a preliminary turn of the rotary plate 5 at an appropriate angle to the front adjustable stop 36 (Fig. 8 and 9).
    Editing of the end face and periphery of the external grinding wheel 13 is carried out by a cantilever mechanism for straightening 12, moreover, using motion on the controlled axes X and Z, (Fig. 10).
    Editing the butt and periphery of the internal
    the grinding wheel 22 is carried out by turning the mechanism 26 for straightening after it has been rotated in the working position by the hydraulic mechanism 37, and using movements on the control axes Xj and Z.
