| titleOfInvention | Method for manufacturing glass blank for magnetic disk and method for manufacturing glass substrate for magnetic disk |
| abstract | When a large number of glass blanks are produced by pressing a lump of molten glass, the thickness of the glass blank is made uniform. When a large number of glass blanks are produced, the pressure value of the press pressure of the die in the press process is adjusted according to the thickness of the molded glass blank. For example, the press pressure is adjusted so that the thickness becomes constant according to the change in the thickness of the glass blank that changes according to the usage history of the mold. Alternatively, when forming a glass blank using a plurality of pairs of molds, the thickness of the glass blank formed by a plurality of pairs of molds so that the thickness of the glass blank formed by the plurality of pairs of molds is uniform. The pressure value of the press pressure in each pair of dies is adjusted according to the difference between the two. [Selection] Figure 2 |
