PURPOSE: A polishing apparatus is provided to polish the entire surface of a base material by pressing a brush to the base material with constant power regardless of the shape of the base material. CONSTITUTION: A polishing apparatus comprises a mounting unit(200), a brush(300), a contact holding unit(400), a rotary motor(500), and a vibration applying unit(700). A base material(10) is positioned on the mounting unit. The brush closely reciprocates to or apart from the base material. The contact holding unit maintains the brush attached to the base material by pressing the brush to the base material. The rotary motor rotates the mounting unit around a vertical rotary shaft to the movement direction of the brush. The vibration applying unit is placed between the mounting unit and a driving shaft of the rotary motor, and transfers vibration to the mounting unit. |
