托尔亚特亭斯克工学院研制成的内冷式车刀,主要用于在车床和立式车床上粗车难加工的钢材。在这种车刀的结构中(图1)应用装有散热器2的热管1,能提高刀具的冷却效果和排除对刀具外给冷却剂的必要性。这种车刀在刀具自动更换的机床上使用方便。 Tolot Tessek Institute of Technology developed by the internal cooling type turning tool, mainly used in rough lathe and vertical lathe difficult to machine steel. In the construction of such a turning tool (FIG. 1), the use of the heat pipe 1 with the heat sink 2 increases the cooling effect of the tool and eliminates the need for coolant to be supplied to the tool. This type of turning tool is easy to use on a machine that automatically changes the tool.
