Embodiment Construction

[0072] A machine tool according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a table traverse type grinder is taken as an example. like figure 1 As shown, the machine tool 10 has: a bed 11; a slender workbench unit 12 that can move along the Z-axis direction on the upper surface of the bed 11; A headstock 13 and a tailstock 14 supporting both ends of the object W; a grinding wheel head 15 movable in the X-axis direction on the bed 11; and a grinding wheel 16 rotatably supported on the grinding wheel head 15 .

[0073] The table unit 12 includes: a traverse table 20 (corresponding to the "base" of the present invention), which can move in the Z-axis direction on the upper surface of the bed 11; and a corner table 30, which is provided in a rotatable manner. on the upper surface of the traversing table 20 ; and an actuator 40 , which adjusts the rotation angle θ of the corner table 30 relative to the traversing...

Abstract

A machine tool that enables a reduction in the amount of deflection of a swiveling table is provided. A machine tool includes a base, a swiveling table that is shaped to be elongate and that swivels while sliding on an upper surface of the base, and an actuator attached to a longitudinal first end of the swiveling table to move a position of the first end of the swiveling table with respect to the base, thereby adjusting a swiveling angle of the swiveling table with respect to the base. The rigidity of the swiveling table against a bending force that bends the swiveling table in a deformed manner in a swiveling plane is set to increase from the longitudinal first end of the swiveling table toward the swiveling center.

Description

technical field [0001] The present invention relates to a machine tool provided with a corner table. Background technique [0002] The machine tools described in Japanese Patent Laying-Open No. 11-77493 and Japanese Patent Laid-Open No. 7-195266 are provided with a cornering operation that slides and rotates on the upper surface of the base in order to perform taper processing or taper correction for forming a tapered portion on a workpiece. tower. The rotation angle of the corner table relative to the base can be adjusted by moving the position of the first end of the corner table relative to the base using an actuator provided at the first end in the longitudinal direction of the corner table. [0003] However, since the length from the vicinity of the rotation center of the elongated corner table to the driving position of the actuator is long, the corner table bends and deforms. Therefore, it is desirable to reduce the amount of deflection of the corner table. Conten...
