Wheels grind artificial eyes

摘要

Industrial abrasive wheels are being used by Moorfields Eye Hospital to help produce its prosthetic eyes. A wax mould is used is used to cast the acrylic plastic that is trimmed back using the Scotch-Brite EXL Unitised Wheel XL-UW, made by 3M, normally used to deburr metal parts in industry. Moorfields makes 1400 customised eyes every year, each of which are hand-made from medical grade acrylic plastic and finished with the abrasive. The Scotch-Brite grinding wheel used is made of a compressed, non-woven fibre.
