Coating apparatus for surface refinement of a workpiece

Abstract

The invention relates to a coating device for surface finishing of a workpiece, comprising at least the following components: a tool chuck for holding a workpiece with a treatment surface; a coating unit with an application axis for application of a finishing layer in a region and along a feeding direction on said treatment surface; and an optical monitoring unit by means of which an application operation on said treatment surface can be detected in a focus region. The coating device is characterized especially in that the focus region of the monitoring unit is directed onto the region of the current application operation upstream of the region in the feeding direction and/or at an inclination with respect to the application axis. With the coating device proposed here, the application quality can be monitored in-line in the coating process.
