To provide a gear machining apparatus capable of correcting a tooth trace error without using a special tool when a hob cutter is cantilever-supported. A gear machining apparatus includes a hob cutter machining a tooth profile on a workpiece, a tool spindle device rotatably cantilever-supporting the hob cutter, a workpiece spindle device rotatably supporting the workpiece, a driving device moving the tool spindle device and the workpiece spindle device relatively to each other, a measuring device measuring the value corresponding to a bending amount of the hob cutter or a rotation synchronization shift of the workpiece spindle device with respect to the tool spindle device and a correction processing unit correcting a cutting amount of the hob cutter T or the rotation synchronization shift of the workpiece spindle device with respect to the tool spindle device based on the value measured by the measuring device.

The damping property of a rear rolling bearing () is adjusted by controlling a damping force that is applied by damping application means () based on, for example, the type of a tool (T). Thus, it is possible to provide the optimum damping properties for various tools that differ in natural vibration, and to suppress the generation of chattering of the various tools. As a result, it is possible to increase the cut amount per unit time to increase the productivity.

Spindle device for machine tool

An apparatus for setting control parameters of a machining apparatus. The setting apparatus includes a storage unit for storing a set of control parameters for each of a plurality of machining modes; an input device for selecting one of the plurality of machining modes; and a control unit for selecting a set of control parameters corresponding the selected machining mode and setting the set of control parameters as control parameters to be used for controlling the machining apparatus.
