  • a second diamond roller for dressing the grinding wheel for internal grinding is mounted on the cross slide of the grinding support for external and face grinding.
  • the slide of the grinding support for external and face grinding arranged at an angle and the right longitudinal slide of the support for internal grinding are only driven when the corresponding grinding wheels are dressed (DD-PS 84 808).
  • the disadvantages of the known cylindrical grinding machine for external and internal grinding are: the complicated kinematics of the support for external and face grinding, which essentially consists of two supports, one of which is only used for dressing the wheel; using an expensive diamond roller with a large diameter for dressing the wheel for external grinding, moreover it does not achieve a high smoothness of the machined workpieces; a longitudinally immovable support for the internal grinding, which leads to large distances between the faces of the discs for external and internal grinding in the working position, which in turn favors the occurrence of errors in the mutual arrangement of the inner and outer surfaces of the machined workpieces; the impossibility of machining a base and an attachment with programmable movements of tapered inner and outer surfaces when combined with outer and inner cylindrical surfaces and forehead surfaces appear in a workpiece; the need to manually change the machine when moving workpieces of one type to another with significant preparation time.
  • the invention has for its object to provide a cylindrical grinding machine for external and internal grinding with NC control, in which the grinding is guaranteed with a base and an attachment of workpieces with multi-stage outer and inner cylindrical and conical surfaces and end faces, namely at high accuracy of their mutual arrangement and the ability to quickly change when changing the type of workpieces.

  • the cross slide of the internal grinding support is mounted on a longitudinal slide which is guided over the longitudinal guides of the body by a device for longitudinal feed.
  • the following devices are installed above the protective shield between the headstock and the grinding support for internal grinding: one for active control during external grinding, one for active control during internal grinding and one for dressing the grinding wheel for internal grinding.
  • a device for the axial positioning of the machined workpiece is mounted on the grinding support for external grinding, and a device for dressing the grinding wheel for external and face grinding is mounted on the headstock at the level of the axis of the machined workpiece.
  • a hydraulic drive cylinder and two hydraulic locking cylinders are mounted on the rotating plate of the headstock.
  • the advantages of the machine according to the invention are: the possibility of automatic grinding of multi-stage inner and outer cylindrical and conical surfaces and end faces when fastening the workpieces and with high accuracy of their mutual arrangement; increasing dimensional accuracy by using facilities to actively control and zero the system when machining is complete; increasing the dressing accuracy of the grinding wheel for external grinding and, as a result, achieving a high smoothness of the machined surfaces; the rapid automatic changeover of the machines when changing the type of workpieces the simple kinematics with essential technological possibilities.
  • a left longitudinal slide 2 and a right longitudinal slide 3 are mounted on the longitudinal guides of the body 1 (FIGS. 1 and 2). These can be set in motion along the body 1 with the aid of two mechanisms of the same construction for longitudinal feed - left 4a and right 4b.
  • a rotatable plate 5 is mounted on the left longitudinal slide 2 with the possibility of angular rotation for grinding conical (outer and inner) surfaces with the help of a hydraulic drive cylinder 6.
  • the rigid attachment and detachment of the rotatable plate 5 to the left longitudinal slide 2 is carried out by two hydraulic locking cylinders 7.
  • the headstock 8 with the spindle 9 mounted therein is rigidly attached, at the front end of which a chuck 10 is fixed with manual, hydraulic or other type of actuation for fastening the machined workpiece 11.
  • a console-type dressing device 12 for dressing the circumference and the end face of the outer grinding wheel 13 is mounted on the headstock 8 in the level of the axis of the machined workpiece 11.
  • a transverse slide 14 with the possibility of a transverse movement is mounted with the aid of a device for transverse advancement of the inner grinding wheel 15.
  • a spindle unit 16 for internal grinding is mounted, which carries a spindle 17 for internal grinding.
  • the arrangement of the spindle 17 to the inner loop may be either parallel to the axis of the machined workpiece 11 (Fig. 3) or at an angle to ⁇ (FIG. 4) take place.
  • a linear measuring system 18 On the side surface of the right longitudinal slide 3, the housing of a linear measuring system 18 is attached, which is provided for the photoelectric measurement of the displacement of the cross slide 14, on which a slider 19 is rigidly mounted.
