Abstract
The present invention relates generally to a device used to process workpieces. In particular, the invention relates to a carrier that is used to support a workpiece during workpiece honing, grinding, or polishing. The carrier includes a rigid core coated with a fiber-free, scratch-resistant material to prevent scratching of workpieces disposed in the carrier. An adhesive layer is typically used to attach the scratch-resistant layer to the rigid core. The adhesive film and the scratch-resistant films may be attached to the rigid core by hot pressing.
