Description

Изобретение относитс  к области обработки металлов резанием, в частности к металлорежущему инструменту.The invention relates to the field of metal cutting, in particular to metal cutting tools.

Известен металлорежущий инструмент, в державке которого закреплен кристалл алмаза, со средством отвода тепла lKnown metal-cutting tool, in the holder of which a diamond crystal is fixed, with a means of heat removal l

Недостатком известного инструмента  вл етс  низка  эффективнос-ть отвода тепла.A disadvantage of the known tool is the low heat removal efficiency.

С целью повышени  эффективности отвода тепла средство отвода тепла вьтолнено в виде охватывающей державку оправки с отход щими от нее стержнеобразными элементами и направленными в сторону кристалла алмаза.In order to increase the efficiency of heat removal, the heat removal means is embodied in the form of a mandrel embracing the holder with rod-like elements extending from it and directed towards the diamond crystal.

На чертеже показан предлагаемый инструмент .The drawing shows the proposed tool.

Описываемый инструмент содержит державку 1 с кристаллом алмаза 2, державку охватывает оправка 3 с отход щими от нее стержнеобразными элементами 4.The described tool contains a holder 1 with a diamond crystal 2, the holder includes a mandrel 3 with stem-like elements 4 extending from it.

При работе инструмента вьщел юще- ес  в зоне резани  тепло эффективно отЬодитс  от поверхности кристалла по элементам 4, которые передают тепло оправке 3.During the operation of the tool, the heat in the cutting zone is effectively removed from the surface of the crystal through the elements 4, which transfer heat to the mandrel 3.

Так как элементы 4 располагаютс  на различных уровн х кристалла, тепло, выдел ющеес  в зоне резани , практически сразу же отбираетс  и отводитс  верхним р дом элементов 4 и частично нижележащими , практически не распростран  сь на нерабочую часть инструмента, что преп тствует созданию благопри тных дл  графитизации условий. По мере срабатывани  кристалла, а следовательно , и вышележащих элементов 4 в работу по отбору и переносу тепла постепенн и с наибольшим,;эффектом вступан т ни .жележащие элементы.Since the elements 4 are located at different levels of the crystal, the heat generated in the cutting zone is almost immediately taken away and removed by the upper row of elements 4 and partially underlying, practically does not extend to the non-working part of the tool, which prevents the creation of good graphitization conditions. As the crystal is triggered, and consequently, the overlying elements 4, the work on the selection and transfer of heat gradually and with the greatest, the effect comes to the underlying elements.
