Title:
MANUFACTURING METHOD FOR OPTICAL LENS
Document Type and Number:
Japanese Patent JP2003103401
Kind Code:
A
Abstract:
To provide a manufacturing method for an optical lens, capable of precisely cutting an optical resin material without polishing work after cutting.
An ion generator 1 is used as a static electricity preventing device to prevent the chips of the optical resin material 4 generating during the cutting operation from electrostatically adhering to a lens machining surface and a turning tool 5. The chips are removed sequentially by a suction pipe during the operation.
