FIELD: machine building.
SUBSTANCE: invention relates to machine tool building and can be used, for example, in grinding machines designs. On grinding machine receiving element (21), for example, on grinding head, grinding spindle unit (10, 27, 55) is installed with possibility of rotation around axis (26) of rotation. Grinding spindle unit carries driven grinding wheel (31), which can be installed at angle to processed part longitudinal axis using adjusting unit (33). At that, pressure bolt (34) is extending, turning grinding spindle unit rotation around axis (26) of rotation. Axis (26) of rotation is made in form of living hinge using bearing part (23, 60) targeted elastic deformation area. Tension spring device (38) provides constant contact of pressure bolt (34) with receiving element (21).
EFFECT: invention increases accuracy of grinding wheel specified installation at angle during inclined or convex surfaces processing.
