Estimating the term…
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. A chip screen is mounted for adjustable movement toward and away from the rest plate.
A router, comprising a drive unit housing, a rotatable cutter shaft extending out of said housing for carrying a cutter, guide column means extending out of said housing in the same direction as that of said cutter shaft, a rest plate having a contact surface for engaging a workpiece, said rest plate guided on said column means for movements toward and away from said housing and having an aperture therethrough for the passage of a cutter on the cutter shaft and aligned with the cutter shaft, said rest plate having a cutting cavity in said contact surface surrounding the aperture and surrounding a cutter carried on the shaft, said cavity extending outwardly for exhausting chips cut by the cutter away from the aperture, said rest place having an exhaust connection with an inlet communicating with said cutting cavity for removing chips from the cavity, a chip screen mounted on said rest plate along the periphery thereof, said chip screen extending parallel to the shaft and being lowerable to a maximum lowered position in a direction parallel to the shaft below said contact surface, a slide stop mounted on said rest plate adjacent said chip screen and extending parallel to the shaft and lowerable below the contact surface in a direction parallel to the shaft, and means on said chip screen and slide stop which are engageable at the maximum lowered position of said chip screen so that said chip screen can be lowered only as far as said slide stop is lowered and said chip screen can be lowered to a lesser extent than said slide stop.
