  • Cutting machine for plate-shaped material
    Patent number: 7316174
    Abstract: When a plate-shaped material, such as a CSP substrate, that does not require exact precision is divided, a cutting machine is provided with not only first and second chuck tables, but also first and second cutting units. Then, each plate-shaped material, which is placed on a respective chuck table, is aligned immediately before it is cut, so that the Y-axis index control and the X-axis cutting movement control are established for cutting by the cutting units. A cutting portion is cut in the first direction by the first cutting unit according to the Y-axis index control and the X-axis cutting movement control, and subsequently a cutting portion is cut in the second direction by the second cutting unit. Hence, the cutting portions of the plate-shaped materials placed on the first and second chuck tables are cut by the first and second cutting units by sharing a role.
