Abstract
NOVELTY - The production process involves clamping a rod blank in a clamping device acting uniformly along opposite sides of it and polishing it with a rotating grinding tool whose axis is parallel to the longitudinal axis of the blank. 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.
