ABSTRACT:
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a power saw machine, and more particularly to a tile cutting guide arrangement specifically incorporated with the power saw machine, which can guide the tile to be cut into a predetermined shape quickly and easily.
2. Description of Related Arts
Power saw is a common machine specially used in cutting and shaping tile or other construction materials made of granite, marble, slate, pave, brick, ceramics, and masonry. A conventional power saw comprises a supporting frame comprising a cutting table slidably mounted thereon, a cutting head arrangement overhanging on the cutting table with a circular saw blade that is powered by an electric motor.
However, the conventional power saw has a major drawback that the power saw does not provide a tile guider for cutting the tile precisely. Especially when the tile is needed to be cut diagonally, a user merely use his or her experiences to adjust the position of the tile on the cutting table. Even though a right triangular shaped tile guider is incorporated with the power saw for guiding the tile on the cutting table, the tile guider can only guide one side edge of the tile such that the tile may force to be misaligned during cutting. Thus, due to the various sizes of the tile, the user always has difficulty to guide the tile by the standard size tile guider.
SUMMARY OF THE PRESENT INVENTION
A main object of the present invention is to provide a tile cutting guide arrangement for power saw machine, which can easily and quickly guide a tile on the cutting table in a corrected alignment.
Another object of the present invention is to provide a tile cutting guide arrangement for power saw machine, which comprises a tile guider having a plurality of rip guides each having a predetermined size for fittedly guiding a corresponding size of tile. In other words, the tile cutting guide arrangement fits for guiding any size of the tile.
Another object of the present invention is to provide a tile cutting guide arrangement for power saw machine, wherein a tile guider securely holds two corners of the tile to ensure the tile is in a right alignment when the tile is cut diagonally.
Another object of the present invention is to provide a tile cutting guide arrangement for power saw machine, which does not require to alter the original structure of the power saw machine, so as to minimize the manufacturing cost of the tile cutting guide arrangement incorporating with the power saw machine having a cutting table.
Accordingly, in order to accomplish the above objects, the present invention provides a tile cutting guide arrangement for power saw machine which comprises a supporting frame, a cutting head arrangement, having a circular saw blade, supported on the supporting frame, wherein the tile cutting guide arrangement comprises:
a cutting table, slidably supported on the supporting frame, having a main cutting channel wherein the saw blade is arranged to overhanging travel along the main cutting channel; and
a tile guider slidably mounted on the cutting table comprising a plurality of rip guides spacedly formed on the tile guider wherein each rip guide has a guiding edge, which is 45 degrees with respect to the main cutting channel, adapted for guiding an edge of the tile, so as to align a diagonal of the tile with the main cutting channel of the cutting table.
