Description
Material for blocking workpieces during the traditional polishing process of high-end precision optical surfaces production.
The wrap tar is placed on the opposite side of the workpiece and, when properly mounted on the tool, prevents the workpiece from moving under the forces that occur during the traditional polishing process. Our blocking pitches is prepared to use directly from the packet without mixing, filtering or other preparation.
At the customer’s request we of course can prepare other hardness and mixture of the pitches.
