CIRCULAR CUTTING PLATE AND MODULAR CUTTER Russian patent published in 2017 - IPC B23B27/16 

FIELD: machine engineering.

SUBSTANCE: radial grooves are made in the side surface of the circular cutting plate central hole. Each groove includes the communicating parts, disposed on the cylindrical and conical sections of the central hole and the lower support surface. On the lower backrest of the modular cutter holder receptor, the recess with cylindrical side surfaces is performed with the hole for coolant supply, and the surfaces are coaxial with the axis of the central hole of circular cutting plate during its installation and fastening in the holder receptor, at that the central angle of the recesses in relation to the axis of the central hole of the cutting plate is more than the central angle between cutting plate, located at the lower support surface and the parts of two adjacent radial grooves.

EFFECT: increase of coolants supply efficiency.
