摘要： The present invention relates to a tool for rotary chip removal machining. The tool comprises a cutting head (10), a retention means (11) and a shank (12). The cutting head (10) is provided with at least one cutting edge (27, 30) which is integral with the cutting head. The cutting head and the retention means comprise overlapping asymmetrical means (15, 19) of separate material for mounting of the cutting head to the shank. The asymmetrical means (15) of the material with highest density comprises a mass diminishing recess (34). In that manner the center of gravity is displaced in the area of the hook-shaped means, closer to the axis (CL) of rotation of the tool and therefore the tool becomes dynamically centered. The invention also relates to a cutting head for the tool.

摘要翻译： 本发明涉及一种用于旋转切屑加工的工具。 该工具包括切割头（10），保持装置（11）和柄部（12）。 切割头（10）设有至少一个与切割头成一体的切割边缘（27,30）。 切割头和保持装置包括用于将切割头安装到柄上的独立材料的重叠的不对称装置（15,19）。 具有最高密度的材料的不对称装置（15）包括质量减小凹槽（34）。 以这种方式，重心在钩形装置的区域中移位，更靠近工具的旋转轴线（CL），因此工具变为动态居中。 本发明还涉及用于该工具的切割头。
