Abstract
A wood working router which comprises a plurality of turret heads adapted to be selectively operated and each having a plurality of radially and outwardly extending tools and the corresponding number of motors for driving the individual tools, a mechanism associated with each turret head for intermittently rotating the turret head so as to move a selected one of the tools to the processing position each time the turret head is rotated, and a workpiece holding and releasing device for holding a workpiece on a sucking table by suction and releasing the workpiece from the sucking action.
Claims6
A wood working router comprising a machine base, a table carriage unit movable in a first direction relative to said machine base, a suction-type workpiece holding table unit movable in said first direction together with said table carriage unit and also in a second direction normal to said first direction relative to the carriage unit, a column secured to and extending uprightly from said machine base, at least one turret head mounted on said column for vertical movement and rotation relative to the column and having a plurality of angularly spaced cutting tools extending radially and outwardly about the turret head, a corresponding number of motors attached to said cutting tools for individually driving the tools, a mechanism for intermittently rotating and vertically moving said turret head and selecting said cutting tools on the turret head and a release mechanism for releasing a workpiece held on said suction-type table unit under suction from the table unit.
A wood working router comprising at least one turret head mounted for rotation about a horizontal axis having mounted thereon a plurality of cutting tools extending radially and outwardly from the head and a corresponding number of motors to which the individual tools are attached to be rotated by the motors, a mechanism for intermittently rotating said turret head to successively move said cutting tools to the processing position and successively holding said cutting tools in the processing position, an annular suction member surrounding each said motor having said cutting tool attached thereto for removing chips by suction generated by the processing operation by the cutting tool and having a suction opening and a suction pipe in communication with a vacuum device and adapted to move into contact with or away from said suction opening of the annular suction member, and a workpiece holding suction table for holding a wood workpiece in said processing position while a multi-step cutting operation is performed on said workpiece.
