摘要： A spindle unit comprises a tool-cramping device to make more rigid a main spindle (2) of a machine tool and allow it to operate at high speeds. The main spindle (2) is a solid shaft of a very rigid material such as cemented carbide and is supported rotatably in a spindle head (1) by bearings (3) which generate only low heat. A tool-cramping device includes an adapter (8) attached to a front end of the main spindle (2), and a tool holder (12) carrying a rotary tool (10), with one of the adapter (8) and the tool holder (12) comprising a short columnar lug (9), and the other comprising a cylindrical bore which can be shrink-fitted tightly onto the lug (9). The member having the bore (13) therein is made of a material of a thermal expansion coefficient higher than that from which the other member is made. The tool-cramping device further comprises means for heating (14) and means for cooling (15) the member (12) having the bore (13) therein.

摘要翻译：主轴单元包括工具夹紧装置，以使机床的主轴（2）更加刚性并允许其以高速运行。主轴（2）是刚性材料（例如硬质合金）的实心轴，并且通过仅产生低热的轴承（3）可旋转地支撑在主轴头（1）中。工具夹持装置包括附接到主轴（2）的前端的适配器（8）和承载旋转工具（10）的工具架（12），其中适配器（8）和工具保持器（12）包括短的柱状突起（9），另一个包括可以紧密地收缩配合到凸耳（9）上的圆柱形孔。其中具有孔（13）的构件由热膨胀系数高于制造另一构件的热膨胀系数的材料制成。工具夹持装置还包括加热装置（14）和用于在其中具有孔（13）的构件（12）冷却（15）的装置。
