High precision milling and fixturing is necessary to produce this part made from aluminum. Used in the ophthalmic industry, this high precision component is critical for proper fit and alignment of multiple lenses and mirrors. This part had eventually been outsourced to China because of competitive prices, but It wasn't more than 3 months later that our customer realized China's prices are not helping business any if the part can't be manufactured properly, and we are currently making this component once again. Our fixturing and milling techniques again have been proven to be second to none.
