DEVICE FOR MICROFEED OF BLANKS AT GRINDING Russian patent published in 2007 - IPC B24B47/20 

FIELD: machine building, applicable for precise feed of blanks at grinding.

SUBSTANCE: the upper plate with a fastener of the blanks is installed on the foundation in parallel with it. Provision is made for two cylindrical guides and springs for returning the upper plate to the initial position and taken up the backlashes. Four wedges are fixed oppositely in pairs on the foundation and upper plate. Four balls installed in two strips fastened on the opposite ends of the power member are positioned on the guides of the wedges for motion on them. The rod of the power member carries a piezoelectric element and a stop, which can move axially relative to the rod and provide for variation of the power member length.

EFFECT: reduced power intensity and enhanced precision and quality of machining, as well as the reliability of the device operation.
