Abstract: Provided is a machine tool hand including a body portion that is mounted so as to be attachable to and detachable from a spindle of a machine tool, and that is provided with a flow path connected to a coolant-liquid supply path formed in the spindle; and two or more hand members that are attached to the body portion such that at least one of the hand members is pivotable about a prescribed axis, and that are capable of gripping an object therebetween by being closed. The flow path is provided with discharge ports via which a coolant liquid supplied from the coolant-liquid supply path is discharged toward surfaces of the hand members that are exposed to an outside, and a pressure of the coolant liquid causes an opening operation or a closing operation of the hand members.

Abstract: A bearing device includes a rolling bearing having an outer ring and an inner ring, an outer ring spacer disposed adjacent to the outer ring, and an inner spacer disposed adjacent the inner ring. The outer ring and the outer ring spacer are fitted to a housing, and the inner ring and the inner ring spacer are fitted to a rotary shaft. The outer ring spacer is provided with a nozzle, which is configured to inject a cooling fluid (R) toward an outer circumferential surface of the inner ring, and is inclined so that an injection port thereof is inclined forwardly in a rotation direction of the inner ring. An inclination angle α of the nozzle with respect to an axial direction is set to a value within a range from 50° to 90°.

Abstract: A machine tool for cutting a workpiece with a cutting tool, includes a spindle motor that generates heat, a spindle head for supporting the spindle motor, and a heat insulating sheet disposed between the spindle motor and the spindle head. The area of a part of the heat insulating sheet that is in contact with a part of the spindle head having a high heat capacity is small so as to increase the amount of heat transferring from the spindle motor to the part of the spindle head having a high heat capacity, and thereby make the temperature distribution of the spindle head uniform.

Abstract: A drive shaft for a machine tool, for example a core drilling machine, able to be connected to a drilling tool, in particular a core bit, is disclosed. The drive shaft contains a cavity which substantially extends over the whole length of the drive shaft and along the rotational axis. The cavity contains at least one inflow opening where, through the at least one inflow opening, water can be fed along the drive shaft into the drilling tool. In the drive shaft, an insertion device is provided in the cavity, through which water is guided for cooling the drive shaft, firstly, in a first direction and then in a second direction, where the water comes into direct contact with the inner side of the cavity at least in the first direction.

Abstract: In a radiating structure for a main spindle having a tapered bore formed at a distal end of the main spindle, into which a tapered portion of a tool holder is mounted, a key fixing member provided with a drive key is fixed to the distal end of the main spindle, and the drive key is fit into a key groove formed in the tool holder. This configuration prevents a phase shift in rotation direction of the tool holder arising from rotation of the main spindle. A radiating member which exchanges heat with an ambient atmosphere is provided to the key fixing member provided with the drive key.
