摘要： A spindle structure in which a noise occurrence due to a tap hole and a screw is effectively prevented. A nut for adjusting a preload of a bearing is threadedly engaged with an outer circumference of a spindle. On an edge of the nut, a plurality of tap holes for balance adjustment are provided at even intervals on a circumference centered around the axis of the spindle and to be parallel to the axial direction of the spindle. These tap holes are countersunk, and a plate screw is threadedly engaged so that an edge of each plate screw is flush with a surface of the nut. In addition, the plate screw is used as a balance weight by changing the length thereof.

摘要： There is provided a cutting method for cutting a work by rotating a rotary tool with a circular cutting edge around an axis while a cutting fluid is supplied thereto. Cutting is performed by means of the rotary tool which is rotated in the same rotational direction as an outflow direction of chips, and the rotary tool is rotated at a rotational speed of the rotary tool at which a circumferential speed of the cutting edge is higher than an outflow speed of the chips. Thus, the area of direct solid contact between the rotary tool and the chips is reduced with the aid of a dynamic pressure effect, and the abrasion of the rotary tool is suppressed.

摘要： A spiral groove flow passage with a clockwise spiral direction and a spiral groove flow passage with a counterclockwise spiral direction are provided inside a spindle. When the spindle is accelerated to rotate in the forward rotation direction, a pressure in the direction of causing a reverse flow of a coolant is applied to the left-hand spiral groove flow passage by the axial-flow pumping action, but a pressure in the forward direction is applied to the right-hand spiral groove flow passage by the same axial-flow pumping action to cancel out the pressure causing the reverse flow described above.
