Machining unit and method for machining a component

A machining unit for machining a bearing component, comprising:

• an industrial robot,
• at least one abrasive tool, wherein the at least one abrasive tool is coupled to the industrial robot,
• a controller in communication with the industrial robot and configured to control the industrial robot,
• wherein the industrial robot is configured to move the at least one abrasive tool through rotational motions, and wherein the controller is configured to control a rotational speed and/or a rotation direction imparted to the at least one abrasive tool by the industrial robot,
• a holder configured to hold the component, wherein the holder is configured to rotate the component, and the controller is in communication with the holder and is configured to control a rotational speed of the component via the holder,
• the controller is configured to control the industrial robot such that a movement path(S) of the at least one abrasive tool such that a contact between the abrasive tool and a surface of the component is in a normal direction relative to the surface, wherein the controller is configured to control the rotational speed of the component and the rotational speed of the at least one abrasive tool such that a ratio of the rotational speed of the at least one abrasive tool to the rotational speed of the component is unequal to an integer or a half integer.
