Wood working machine

A wood working machine (1), in particular a circular saw (1), comprising a machine table (3) on which two guide rails (6a, 6b;

• 206a, 6b;
• 306a, 6b) are fastened and which is penetrated by a working tool (2), and an extension element (5) which for widening of the machine table (3) presents an extension plate (8) in particular flush on top with the machine table (3) and which can be positioned adjacent to the machine table (3) in an extension direction (A), as well as two extension arms (7a, 7b) fixed to the extension plate (8) and received in a guided manner in the guide rails (6a, 6b;
• 206a, 6b;
• 306a, 6b) in the extension direction (A) so that the distance of the extension plate (8) to the machine table (3) is modifiable with
• each guide rail (6a, 6b;
• 206a, 6b;
• 306a, 6b) being penetrated by a guide groove (6a, 12a, 6b, 12b;
• 206a, 12a, 206a, 6b;
• 306a, 12a, 6b, 12b), and a sliding portion (7a, 11a, 7b, 11b;
• 7a, 111, 7b, 111;
• 7a, 211, 7b, 211) being provided on each extension arm (7a, 7b) which sliding portion comprises an external cross section corresponding to the internal cross section of the guide groove (6a, 12a, 6b, 12b;
• 206a, 12a, 206a, 6b;
• 306a, 12a, 6b, 12b) so that each extension arm (7a, 7b) with its sliding portion (7a, 11a, 7b, 11b;
• 7a, 111, 7b, 111;
• 7a, 211, 7b, 211) is guided slidingly in the allocated guide groove (6a, 12a, 6b, 12b;
• 206a, 12a, 206a, 6b;306a, 12a, 6b, 12b),
• characterised in that
• the extension element (5) is formed for retrofit from the machine table (3) side located in the extension direction (A) to the opposite machine table (3) side with extension arms (7a, 7b) fitted to the extension plate (8) in order to widen the machine table (3) optionally on the one or on the other side and that the two guide rails (6a, 6b;
• 206a, 6b;
• 306a, 6b) are formed for receiving and removing the allocated extension arms (7a, 7b) are formed in a condition of the said guide rails fastened to the table with the extension plate (8) positioned optionally on the machine table (3) side located in the extension direction (A) or with the extension plate (8) positioned on the machine table (3) side located in the opposite direction, with
• the extension arms (7a, 7b) being located in an axially symmetrical manner, of equal dimension and formed as profiles or sections with constant cross section, and the wood working machine comprising a rip fence module (9) guided shiftably on and/or in the extension arms (7a, 7b).
