Patent ID: 6846228

Claim:
A structure for a polishing machine of an optical disk comprising: a motor, a turntable unit integrated with a housing, at least two polishing wheels positioned on a cover which can cover said housing, and a timer, wherein said motor is fixed in said housing with a predetermined strength, said turntable unit is fixed at a front portion of a spindle of said motor, said turntable unit comprises a fixing ring, a circular supporting plate, a buffer pad, a positioning button, and a nut cover, said fixing ring is fixed at a front end of said spindle of said motor by a screw, said circular supporting plate with a predetermined strength and a soft buffer pad are positioned above said fixing ring in series by a positioning button with a screw bar at both ends, a nut cover with inverted bowl shape and screw inside is screwed on said positioning button to fix an optical disk on a buffer pad, a spindle shaft is positioned in a base of said polishing wheel, a screw bar and a screw ring are extended and positioned in a center of said spindle by tight screwing of said screw bar, said screw ring is tightly fastened to enhance fixity of said polishing wheels and make them freely rotatable, surface of one of said polishing wheels presses on data zone and covers an inner half region of said optical disk, surface of the other one of said polishing wheels covers an outer half region and said cover can cover components of said housing that can at least exchange the optical disk when opened and can fix the components when closed, said timer is connected to a power circuit of said motor in series to stop said motor when said motor is rotated for a predetermined time so as to precisely control polishing time of the optical disk.
