Abstract
A device for polishing of a multi-surface workpiece is described. The device includes a base and a vertical motion platform that moves along two support rods, which carries a motor that drives a rotating shaft. The support rods extend from said base. A polishing tool is attached to the motor shaft. The workpiece being polished is placed on a linear motion stage during the polishing process.
Claims20
A device for polishing of a multi-surface workpiece, the device comprising:
- a base;
- a vertical motion platform having a weight guide;
- a motor disposed on the vertical motion platform, wherein said motor drives a rotating shaft;
- two rods extending perpendicular from said base, wherein the rods support the vertical motion platform while it moves in a direction parallel to the base;
- free weights attached to the weight guide, wherein said weights ensure equal distribution of weight around the motor shaft;
- a polishing tool attached to said rotating shaft, wherein surfaces of said workpiece are in contact with said polishing tool;
- and
- a linear stage having a support base plate;
- wherein said linear stage moves in any direction parallel to the base and vertical motion platform, and wherein said linear stage is disposed below the floating platform and wherein the workpiece is reversibly attached to the linear stage support base plate.

A method of polishing of a workpiece comprising:
- placing the workpiece on a tray;
- reversibly attaching the workpiece to the tray using an adhesive;
- wherein said tray is attached to a support base and wherein said support base is in turn attached to a linear motion stage wherein the linear motion stage is capable of moving to in any horizontal direction;
- installing a polishing pad on a polishing tool;
- attaching the polishing tool on a rotating shaft;
- attaching the rotating shaft to a motor installed on a vertical motion platform;
- wherein said vertical motion platform is disposed above the workpiece reversibly attached to the tray;
- beginning the rotation of the polishing tool;
- lowering the polishing tool to the workpiece;
- contacting the rotating polishing pad with workpiece surfaces;
- moving the linear motion stage and the vertical motion platform to polish each region of the workpiece;
- detecting the surface profile of the workpiece;
- ceasing the rotation of the polishing pad upon detection of a smooth surface on the workpiece;
- raising of the vertical platform and the polishing tool;
- and
- removing of the workpiece.
