<p>Disclosed is a low-cost polishing device provided with: a high polishing ability for eliminating microfissures that exist on the surface of a polygonal column shape comprising a hard material; and a fine polishing ability that eliminates surface irregularities and reduces surface roughness. Further disclosed is a method for polishing same. The polishing device is provided with: a base (4) on which the machining surface (P) to be polished of a object (W) to be polished is loaded horizontally facing upwards; a clamping means (5) that clamps both ends of said object to be polished; a polishing unit (1), which clamps both ends of the aforementioned object to be polished, polishes, ends the clamped state after polishing completion, automatically rotates said object to be polished by means of manual rotation or a rotating means (14A, 14B), causing the next machining surface to be horizontal facing upwards, and which moves a polishing means (2) provided with a polishing tool (10) that rotates while contacting and polishing the edge of said machining surface; and a height-position detection means (3) that detects the height position of the machining surface of the aforementioned object to be polished and enables the automatic setting of the amount of cutting into the machined surface by the polishing tool of the aforementioned polishing means.</p> |
