Abstract

The invention relates to a machine tool industry, namely to tools for machining deep holes with an internal flow of coolant. The aim of the invention is to improve the accuracy of processing. Before starting work, a plug 5 is inserted into the stem 1 with an axial channel 2. The plug cavity 9 is positioned so that the radial hole 12 is connected to channel 2 through a longitudinal throttle hole 10, a variable annular groove of the depth and the cavity 9. Then insert the tool in the reference hole and fed into the channel 2 coolant under a given pressure. Then, the plug 5 is turned over the protrusion 7 until the coolant with the required flow, which provides cooling of the cutting element 4 attached to the stem 1 from the side opposite to the groove 3, goes from the hole 12 to the longitudinal groove 3 on the outer surface of the stem 1 and sufficient to provide hydrostatic support on the groove 3. Then the plug 5 is fixed and the tool is ready for operation. During operation, the coolant provides compression of the cutting element 4 to the treated surface and its cooling. 3 il.
