Patent ID: 8672730

Claim:
A machine for simultaneously forming a concave or convex radius surface on a plurality of work-pieces comprising: a first platform including a plurality of work-piece receiving areas that are each configured to accommodate a work-piece; and a second platform positioned adjacent the first platform, the second platform including a plurality of substantially hollow rotatable tools each of which includes a circumferential surface that is configured for forming or polishing a radius surface on a work-piece, wherein each hollow rotatable tool corresponds in position to a work-piece receiving area of the first platform; wherein an axis of rotation of each tool is oriented at an oblique angle with respect to a longitudinal axis of a corresponding work-piece and a longitudinal axis of a corresponding work-piece receiving area; a press is included for translating the second platform with respect to the first platform, or vice versa; the first platform includes a removable tray positioned on top of a housing for accommodating the work pieces, the removable tray includes the plurality of work-piece receiving areas that are each configured to accommodate a single work piece, the removable tray includes a top surface and a series of through-holes defined on the top surface, each through-hole sized to receive a work piece, each work piece receiving area corresponds in position to one of the rotatable tools of the second platform, the first platform includes a plurality of rotatable carriers, each rotatable carrier configured to rotate a respective work piece, when the respective work piece is positioned in the removable tray, the first platform includes means for simultaneously rotating all the rotatable carriers in a first direction, and the second platform includes means for simultaneously rotating all the rotatable tools in a second direction, opposite to the first direction; and wherein the work pieces are configured to be positioned in the removable tray, and the removable tray is configured to be positioned on top of the housing and in position for rotation by the rotatable carriers, and the means for rotation are configured to simultaneously rotate all the rotatable carriers in the first direction and all the rotatable tools in the second direction.
