Document Type and Number:
Japanese Patent JP7338339
Kind Code:
B2
Abstract:
To improve quality of a hole.SOLUTION: A spectacle lens processing device, which processes a hole in a spectacle lens by a hole processing tool held by lens holding means, comprises: transfer means which relatively changes a positional relationship between the spectacle lens held by the holding means and the hole processing tool; hole data acquisition means which acquires hole data with a desired hole depth and a desired contour shape which is expanded with respect to a diameter of the hole processing tool; and control means which controls the transfer means on the bases of the hole data. The control means performs at least two stages of short-distance expansion processing comprising: first processing that moves the hole processing tool in an axial direction of the hole processing tool, and processes a hole at a distance shorter than a distance of the desired depth; and second processing that moves the hole processing tool in an expansion direction orthogonal to the axial direction to expand the hole in the state that a depth position of the hole processing tool in the first processing is maintained.SELECTED DRAWING: Figure 7
