SET OF SHORT CONE TOOLS AND METHOD FOR PROCESSING LONG CONE HOLES WITH A SET OF SHORT CONE TOOLS

摘要

FIELD: tool engineering. ;SUBSTANCE: set is designed for processing long cone holes with a length of more than 10 medium diameters with short axial cone tools by sequentially placing them in the machine spindle. In this case, the first cone tool is made with the possibility of direct placement in the spindle of the machine, and the second and subsequent ones with the help of an intermediate tail element. For sequential movement of tools, the length of the tail element of the next tool in the queue is determined by the given ratio. On the tail part of the first cone tool and on each tail element there is a locking ring fixed with a pin placed respectively in the hole of the tail part of the first cone tool or tail element. At the same time, an anti-vibration ring is installed on the tail of each cone tool, except for the first one, and chip-breaking grooves are made on the cutting edges of the cone tools. The method involves the use of a number of short axial cone tools with a length equal to or greater than the length of the hole. In this case, the shape of the short cone tools coincides with the shape of the hole being processed. The introduction of these tools into the workpiece begins with a cone tool with the largest average diameter to prepare the hole section for the installation of the next cone tool and ends with a cone tool with the smallest average diameter. ;EFFECT: possibility of processing long conical holes is provided. ;2 cl, 7 dwg
