Therefore, there exists a need to firmly secure a large work-piece to a smaller milling machine table such as when the size of the work-piece extends beyond the edge of the milling machine table and does not allow access to the T-slots on the top of the table.Īccording to its major aspects and briefly stated, the present invention is a clamping device for securing an oversized work-piece to a milling machine table, especially to a smaller milling machine table. If the work-piece is larger than the available table, there is often no means of securing the work-piece to the table even if the individual features being machined are small enough for the smaller milling machine to produce them. In relative terms, a larger work-piece generally requires a larger milling machine which, in turn, comes equipped with a larger table with more clamping space.

Usually, the size of work-piece itself is limited to the size of the table on the milling machine or the extent of the feature(s) being machined. The table with the attached work-piece may then be moved in three dimensions either manually or by computer (CNC) as the milling machines'cutting tool engages the work-piece.

Those slots accommodate a variety of different clamps, fixtures, grips and T-shaped bolts that are used to hold a work-piece firmly in place. Most milling machine tables have T-shaped slots that traverse the top of the table. There are many different methods that machinists use to hold a work-piece to a milling machine table so that machining operations and statistical measuring processes can be performed on the work-piece. Milling T slots is a $1,000 solution to a $5 problem. And removing mass/weight from a machine tool (remilling T slots), who's virtue of mass/weight is an asset seems anti-themetic to me. Milling table=not cheap, not easily replaced, easy to muck up. T nuts=cheap, easily made and modifiable. The present invention relates generally to the manufacturing and machine tool industry, sometimes known as toolmaking.
