PURPOSE: A groove processing apparatus is provided to process a groove on the side surface of a plate without a gap even if a flange unit is formed on the side surface of the plate. CONSTITUTION: A groove processing apparatus comprises a cutting member(110), a first drive unit, and a second drive unit(150). The cutting member cuts the side surface of a plate. The first drive unit moves the cutting unit to first and second positions. The second drive unit moves the cutting member in the groove processing direction of the plate. The first position corresponds to one of two sides of a triangular shape. The second position corresponds to the other one of two sides of the triangular shape. |
