Method and apparatus for manufacturing a frame work for shadow mask |
摘要 |
After assembling a framework in an approximately rectangular form, a basis plane is formed by grinding a bottom surface of the framework. Then, ends of two opposing sides of the framework on a side opposite to the basis plane are cut in a predetermined shape by shearing. The grinding can be carried out by placing the framework on a grinding surface that is running, while applying substantially no pressurizing force other than the self weight of the framework. According to this method, precision of forming end faces of a framework on which a shadow mask is mounted can be improved. Also, working time can be shortened.
