The directions for the laser beam machining device and the laser machining method that the lens for an optical focus is single, a laser machining device, and a laser machining device

Document Type and Number:

Japanese Patent JP6253410

Kind Code:

B2

Abstract:

A laser beam machining device (1) is provided, in which unfocused light (A) from a light exit point (B) is radiated onto a single lens (8), wherein the lens (8) focuses the laser light (A) and guides it onto a machining point of a workpiece (7). A distance (m_a, m_b) between the lens (8) and the light exit point (B) and a distance (l_a, l_b) between the lens (8) and the machining point of the workpiece (7) and a distance between the light exit point (B) and the aforementioned machining point can be varied. Moreover, a process of usage of a laser beam machining device (1) is provided.
