PURPOSE: A mirror-face rolling apparatus for workpieces is provided to prevent the deformation of a burnishing tool, a rotary shaft, and a body portion by preventing friction heat between the burnishing tool and the body portion and between the burnishing tool and the rotary shaft due to the installation of first and second bearings. CONSTITUTION: A mirror-face rolling apparatus(1) for workpieces comprises a fixing unit(10) and a burnishing unit(20). The fixing unit is fixed to one side of the work piece and rotates the work piece. The burnishing unit burnishes the exterior of the work piece to be flat. The burnishing unit comprises a body portion, a rotary shaft(22), a burnishing tool(23), a first bearing, and a second bearing(25). The both ends of the rotary shaft are supported on a pair of support units of the body portion. The burnishing tool is coupled with the rotary shaft in the vertical direction to be rotated. The first bearing is located between the burnishing tool and the rotary shaft. |
