Abstract: A deburring apparatus for finishing workpieces includes machines having rotary tools and a gyro-finishing machine. The workpieces are conveyed by an intermittently-driven charging conveyor with a given pitch. The workpieces are transferred from the conveyor to each machine or held at stations of the rotary tools. The machines operate in parallel with each other and successively on all workpieces.
Abstract: A deburring method for finishing workpieces by machines using rotary tools and a gyro-finishing machine successively includes conveying the workpieces by an intermittently-driven charging conveyor with a given pitch, transferring the workpieces from the conveyor to each machine or holding the workpieces at stations of rotary tools. Such steps and processes are performed in parallel with each other and successively with all workpieces.
Abstract: Recipro-finishing methods and machines in and by which workpieces having a curved profile are subjected to both reciprocating and rocking movements in a finishing trough containing finishing media.
Abstract: Automatic centrifugal barrel finishing machine of the type which includes a turret turning on its central axis at a high speed and carrying a plurality of barrels open at top which rotate on their own axes and revolve around the turret central axis, comprising a plurality of barrel holders rotatably and revolvably mounted on the turret and each carried by a dual-rotary shaft structure which consists of an outer hollow shaft and an inner shaft equipped at one end with a chuck engageable with a barrel mounting shaft thereby mounting barrels in position to the barrel holders, and an indexing table carrying a plurality of barrels at different stations and rotating through predetermined indexing steps to place the barrels in position for mounting one barrel to the turret holder while placing other barrels in position for discharging the contents therefrom and charging new contents therein, the operations of the indexing table being operatively associated with the operation of the turret and performed in parallel w
Abstract: An improved vibratory finishing apparatus with a vibratory finishing tub formed like a hollow circular annular trough disposed in a horizontal, ascending- or descending-slope arrangement, the tub having therein a limited accumulating space defined by a known stationary dam of triangular shape at the bottom, a known movable flap member provided with an anti-backflow member thereon, at least one guide plate for guiding a mass including workpieces and media into the space and preventing the backflow of the mass, and at least one closure rigidly or removably mounted on upper open portions of the tub and for controlling the flow of the mass moving up in the space. As a flow of the mass is pushed into the space, it is accumulated to form an accumulated mass which is then pushed out onto the mass separating device or sieve. The space so constructed serves to prevent the backflow of the accumulated mass, and ensures an increased rate of finishing work and a better mass separation.
