Abstract:
1. A cutting machine comprising: a base; a worktable provided on said base and having a working surface and a lateral side; a cutter provided on said worktable; and an elongate fence having first and second long edges that are opposite to each other in a transverse direction relative to the length of said fence, said fence being pivoted to said lateral side of said worktable so as to be rotatable relative to said worktable about an axis, said axis being disposed between and being spaced apart from said first and second long edges of said fence in said transverse direction by first and second distances, respectively, and being spaced apart from said working surface of said worktable by a third distance; wherein said first distance is greater than said third distance, while said second distance is not greater than said third distance; wherein said fence is rotatable about said axis between first and second positions, and is formed with a pair of opposing long grooves indented inwardly from said first long edge of said fence and extending along a first curve centered about said axis, and a pair of opposing short grooves indented inwardly from said second long edge of said fence, extending along a second curve centered about said axis, and disposed between said long grooves, said cutting machine further comprising a holding unit that includes a pair of screw members extending through said fence and engaging threadedly said lateral side of said worktable so as to hold said fence to said worktable, one of said screw members extending through a selected one of said long grooves, the other of said screw members extending through one of said short grooves that is distal from the selected one of said long grooves when said fence is rotated to a corresponding one of said first and second positions.
