Disclosed is a device for angularly precise machining of a workpiece (9) by a tool (3) guided on a guide rail (2), wherein the tool may be, in particular, an electrically-operated hand tool such as a router or circular saw, etc., consisting of a one- or two-piece working panel (1), wherein the working panel (1) of the device is provided with a plurality of receptacles (4), which are arranged in suitable relation to each other and which serve to receive positioning devices (8) without play and perpendicularly to the working panel (1) such that, on one side, a workpiece (9) and, on the other side, a guide rail (2) for guiding a tool (3) can be positioned on or fixed to the working panel such that a defined and reproducible machining angle (11) forms between the face of the workpiece (9) to be processed, which rests against the positioning devices (8), and the guide rail (2), which is placed upon the workpiece (9) to be machined in order to guide the tool (3), which machining angle can be varied by re-inserting at least one of the positioning devices (8) into one of the receptacles (4) and/or by using positioning devices (8) of differently sized cross-sections, wherein the cross-section may be circular or even non-circular, wherein intermediate angles or “crooked” angular value can also be repeatedly set for machining by positioning devices (8), which are rotatable, non-circular in shape or eccentrically mounted, and may be fixed in their rotation. |

1. A device for the machining of a workpiece (9) by a tool (3) which can be in particular an electrically operated hand tool such as a router, circular saw and plunge saw, guided on a guide rail (2), under a precise and definite angle (11) consisting of a work-plate (1) made from one or two superimposed pieces, characterized in that the work-plate (1) contains a variety of holes (4) which are located in an appropriate relation to each other allowing to mount position devices (8) to the work-plate (1) free of play and rectangular to it and in a way that allows to have a workpiece (9) and a guide rail (2) for guiding a tool (3) positioned or/and fixed on them in such a way that a definite and reproducible angle (11) between that side (10) of the workpiece (9) that is positioned at the position devices (8)and the guide rail (2) is established which can be varied by relocating at least one of the position devices (8) into another hole (4) or/and by using position devices (8) of different diameter, whereas their cross-section can be round or out-of-round while allowing to define intermediate angles (11) repeatable through rotatable position devices which can be fixed in their rotation and are out-of-round shaped or mounted eccentrically. |
