To provide a gear processor which can reduce wasteful power consumption at the processing of a gear by making rotational speeds of a workpiece and a gear-cutting tool synchronized with each other, and a gear processing method.SOLUTION: A gear processor 1 comprises a control device 100. The control device 100 has a state value determination part 122 and a variation condition change part 123 which constitute a variation condition setting part 120. The state value determination part 122 acquires a state value indicating a processing state of a workpiece by the gear-cutting tool with respect to the processing of the workpiece, and determines the state value on the basis of a preset reference value. The variation condition change part 123 changes at least either of a rotational speed variation width indicating a variation width when varying the rotational speed of synchronized rotation, and a rotational speed variation frequency indicating a frequency when varying the rotational speed according to a determination result by the state value determination part 122.SELECTED DRAWING: Figure 4 【課題】工作物及び歯切り工具の回転速度を変動させながら同期させて歯車を加工する際における無駄な消費電力量を低減できる歯車加工装置及び歯車加工方法を提供すること。【解決手段】歯車加工装置１は、制御装置１００を備える。制御装置１００は、変動条件設定部１２０を構成する状態値判定部１２２及び変動条件変更部１２３を有する。状態値判定部１２２は、工作物の加工に関して歯切り工具による工作物の加工状態を表す状態値を取得すると共に、予め設定された基準値に基づいて状態値を判定する。変動条件変更部１２３は、同期回転の回転速度を変動させる際の変動幅を表す回転速度変動幅、及び、回転速度を変動させる際の周波数を表す回転速度変動周波数の少なくとも一方を、状態値判定部１２２による判定結果に応じて変更する。【選択図】図４
