摘要： An apparatus and method for forming aspherical lenses is provided in which a holder holds and rotates a predetermined lens workpiece, with a rotation detecting device provided for detecting the rotation angle of the workpiece. The cutting bit is mounted to swing about an axis perpendicular to the axis of rotation of the workpiece holder, with the cutting bit holder also linearly reciprocated. The swing angle and linear extent of the cutting bit or cutting bit holder are also detected, such that the swinging and reciprocating movement can be coordinated and controlled. The method and apparatus is particularly advantageous in forming aspherical and irregular lens shapes.

摘要： A lubricant is supplied to a bearing for a rotary shaft by an oil pump capable of discharging the lubricant at different flow rates depending upon its speed of operation. The oil pump is preliminarily operated to allow the user to derive and determine a relationship between temperature rise in the bearing and the flow rate of the lubricant by the oil pump with rate of rotation of the shaft as parameter. An optimum flow rate at which the temperature rise is minimized can be determined from such a relationship. The oil pump is operated such that the lubricant is discharged at this optimum flow rate and according to the current rotary speed of the shaft. Corresponding to different rotary speeds of the shaft, a temperature characteristic curve representing these optimum flow rates of the lubricant can be obtained, and this temperature characteristic curve may be used to vary the speed of operation of the oil pump to change the flow rate of the lubricant according to different rotary speeds of the shaft. When it is desired to increase the temperature of the bearing faster such that it can reach its saturation point more quickly, the oil pump can be operated such that the flow rate of the lubricant will be much greater than the optimum rate determined as described above and then reduced after the saturation point is reached.
