摘要：A spin casting machine having a gyro rotor which stabilizes the spindle in thevertical position. The weight of the heavy rotating wheel provides the inertial resistanceto speed changes to provide smooth continuous rotation at the selected speed. Lensesspun cast on such a gyroscopically stabilized rotor shaft will be of high optical quality andreproducible.
