Machining unit and method for machining a component

A method for machining a bearing component comprising:

• providing an industrial robot, and at least one abrasive tool, wherein the at least one abrasive tool is coupled to the industrial robot, and a controller, wherein the controller is configured to control a movement path (S) of the at least one abrasive tool such that a contact of the abrasive tool is in the normal direction to a surface of the component, and
• controlling a movement path of the at least one abrasive tool such that a contact of the abrasive tool is in the normal direction to a surface of the component.

A bearing component for a large diameter rolling bearing comprising:

• a bearing component an industrial robot, and at least one abrasive tool, wherein the at least one abrasive tool is coupled to the industrial robot, and a controller, wherein the controller is configured to control a movement path (S) of the at least one abrasive tool such that a contact of the abrasive tool is in the normal direction to a surface of the component, and wherein the bearing component has an arithmetic average surface roughness Ra of less than 0.5 μm, preferably between 0.05 μm and 0.5 μm.
