At least the last working run is made at a depth at which brittle fracture is avoided. DETAILED DESCRIPTION - The clamping device has a triangular-section base body (2) with an edge partly flattened into a resting surface (3) of the width of the blank, and a stop surface (4). USE - E.g. for micro-lenses and micro-arrays. ADVANTAGE - Can produce products in small and medium batches to high precision.de608670658patent1998-19802976
