Claims

[Claims for Utility Model Registration] (1) A spindle head having a spindle formed with a tool holding portion and a casing containing a motor directly connected to the spindle, wherein the tool holding portion of the spindle and the motor are connected to each other. A spindle head consisting of a spindle support section consisting of a plurality of angular bearings in between. (2) The spindle head according to claim 1 of the utility model registration claim, which is constructed by providing a heat insulating material between the spindle support portion and the motor. (3) The spindle head according to claim 1, wherein the casing is provided with a protruding head having a diameter smaller than that of the casing, and a spindle support portion is provided within the protruding head. (4) A machine tool having a machine body and a ram movably installed in the machine body in the vertical direction, wherein the ram is provided with a spindle head according to claim 1, 2, or 3 of the utility model registration claim. . A support structure for a spindle head configured to support the spindle head via a casing of the spindle head with the axis oriented in the direction of movement of the ram.
