    • PROBLEM TO BE SOLVED: To provide a machine tool equipped with a cooling mechanism capable of efficiently suppressing heat conduction. SOLUTION: A spindle motor which is a heating element, and a spindle head provided with a spindle driven by a spindle motor, are connected through a cooling flange 3. The cooling flange 3 is provided with a cooling passage 4 gradually enlarged in cross-sectional area from a gas inlet 4a to a gas discharge port 4b. When high pressure gas is filled from the gas inlet 4a, the high pressure gas is adiabatically expanded and cooled by the cooling passage gradually increased in cross-sectional area, and conduction of heat generated at the spindle motor, to the spindle head is suppressed by the cooling flange 3. Unlike the case of simply allowing refrigerant gas to flow, a cooling effect by adiabatic expansion is also utilized to efficiently prevent/suppress heat conduction. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种配备有能够有效地抑制热传导的冷却机构的机床。 解决方案:作为加热元件的主轴电动机和具有由主轴电动机驱动的主轴的主轴头通过冷却法兰3连接。冷却凸缘3设置有逐渐扩大的冷却通道4 从气体入口4a到排气口4b的横截面积。 当从气体入口4a填充高压气体时,高压气体被横截面积逐渐增加的冷却通道绝热膨胀和冷却,并且主轴电机产生的热传导到主轴头被抑制 冷却法兰3.与简单地允许制冷剂气体流动的情况不同,通过绝热膨胀的冷却效果也被用于有效地防止/抑制热传导。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a temperature control system for a machine tool capable of promptly coping with surrounding temperature changes. SOLUTION: A machine tool mechanism 2 for the machine tool 1 is covered with a machine tool cover 3. Air subjected to temperature control by a temperature controller 6 flows in an air bearing flow passage 4 through a pipe 5 and is discharged from a bearing part of the air bearing provided at the machine tool mechanism 2 into a range covered with the machine tool cover 3. There is provided a branch pipe 9 for directly injecting a part of air discharged from the temperature controller 6 to a temperature sensor 10a disposed in the machine tool cover 3. The temperature sensor 10a measures a temperature of air in which air directly injected from the pipe 9 and air in the machine tool cover 3 are mixed in a predetermined ratio. The measurement result of the temperature sensor 10a is fed back to the temperature controller 6, thus controlling the temperature of air supplied to the bearing. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供能够及时应对周围温度变化的机床的温度控制系统。 解决方案:机床1的机床机构2被机床盖3覆盖。受温度控制器6的温度控制的空气通过管道5流入空气轴承流路4,并从 将设置在机床机构2的空气轴承的轴承部分设置在被机床盖3覆盖的范围内。设置有分支管9,用于将从温度控制器6排出的空气的一部分直接喷射到温度传感器10a 温度传感器10a测量从管9直接喷射的空气和机床盖3中的空气以预定比例混合的空气的温度。 温度传感器10a的测量结果被反馈到温度控制器6,从而控制供应到轴承的空气的温度。 版权所有(C)2009,JPO&INPIT
