Apparatus and method for machining hole for optical film

Abstract

Provided are a hole machining apparatus for an optical film, comprising: a clamping part for fixing a plurality of optical films in stacked laminated state; and a machining part for performing a hole operation on a predetermined region of the plurality of optical films so as to sequentially pass through the optical films along the laminated direction in a state where the optical films are fixed to the clamping part, wherein upon the hole operation, the machining part comprises a drill part provided to perform a primary hole machining operation and a bite unit provided to perform a secondary hole operation in the primary hole operation region. Also provided is a hole machining method for an optical film, comprising clamping a plurality of laminated optical films at a predetermined pressure in the hole machining apparatus.
