Abstract: A functional component usable for demonstration and/or training purposes which is releasably secured to the mounting surface of a support base (1) and for this purpose it is provided with a securing device engageable with the support base (1). The securing device (8) is formed as a clamp (11) which is provided with a clamping component (15) projecting on the underside of the functional component (5) and which engages a mounting recess (93) in the support base (1). The clamp (11) includes an actuating element (22) that permits the clamping component (15) to be mounted manually and without any tool between a clamped position and a released position, whereby, in its clamped position, it is prestressed transversely (16) to the mounting recess (3) against the surface of the mounting recess (3) and, in its released position, operates with a lesser prestress against the recess surface or is removed therefrom.

Abstract: A chip collecting device for a routing tool is in the form of a hood or box having a wall surrounding part of the circumference of the routing bit. Chips thrown tangentially outwards from the bit are guided by the wall onto an upwardly sloping ramp when they pass into the suction current of a dust aspirating means that acts in an upward direction adjacent to the bit. The chip collecting hood or box is mounted on the lower side of an L-shaped stop in rails. The stop has a passage for the chips placed over the ramp.

Abstract: A router comprises a cage supporting a drive unit having a shaft on which a cutter can be fixed. A rest plate is provided with an aperture for moving the cutter therethrough. The rest plate is connected to the cage through two guide columns on which it is displaceable in axial directions of the cutter and arrestable in a selected position. The rest plate is a hollow structure open downwardly where it is closed by a detachable cover having a smooth outer surface. A cavity of the plate communicates with and encircles the aperture 21 for the cutter and grows toward an exhaust connection which extends tangentially to the cutter, i.e. in the direction in which the millings are thrown. The exhaust connection can be connected to an exhauster. Laterally on the rest plate, an adjustable slide stop may be provided having an angled leg which can be brought into a position flush with the bottom surface of the rest plate or moved downward therefrom.

Abstract: The spindle can be rotated by way of a set wheel, and thus displaced within the spindle guide. At the end of this displacement, the spindle butts against one of the set screws of a turret stop provided on the rest plate. The spindle can be locked to the respective set screw by way of a swing extension. The spindle may be hollow to pass therethrough a tool and finely adjust the set screw already locked to the spindle.
