Abstract:
A tool assembly having a tool block (50) and a tool holder (12). The tool block has a fluid passage (92) having an outlet (93). A fluid passage (104) in the tool holder shank (14) has an inlet (102) including a shallow recess (99) configured to maintain fluid communication through a range of relative movement of the block and holder. The fluid passage terminates in a discharge orifice (114) to direct a fluid jet at the chip being removed from the workpiece.
Abstract:
A ball lock assembly having a cutting head (22) and a locking component (24) including a lock rod (94) carrying at least one locking member (105). A positioning assembly (50) operatively connects to the lock rod so that one can move the lock rod between a locked position and an unlocked position. In the locked position the locking member engages the cutting head to hold the cutting head to the locking component. In the unlocked position the locking member does not engage the cutting head so that the cutting head is not held to the locking component.
Abstract:
A cutting toolholder assembly for holding a cutting tool (26) used in a material removal operation. The assembly comprises a locking component which contains a bore (32) with at least one recess (34) therein. The assembly also includes a tool holding component (24) with a shank (48) whereby the bore receives the shank. The shank contains a compartment (50) with a locking assembly within the compartment. The locking assembly includes at least one locking member (56) and a positioner assembly (58) that selectively positions the locking member into engagement with its corresponding recess. The recess corresponds to the shape of the locking member such that when the locking member engages the recess, the recess restrains the locking member so that there is essentially no movement between the holder component and the locking component during a material removal operation.
Abstract:
A toolholder (10) includes a support (12) having an insert seat (18) for receiving a cutting insert (20). The cutting insert (20) is brought into engagement with a workpiece to remove a chip of metal from the workpiece. The toolholder (10) includes fluid chip-breaking means for directing a stream of high velocity fluid at the chip being removed from the workpiece to break the chip into small segments. The direction of the fluid stream can be adjusted so that a single tool can be used to perform a variety of cuts while optimizing the effectiveness of the fluid chip-breaking stream for each cut.

Abstract:
Un porte-outil (10) comprend un support (12) ayant un siège d'insert (18) recevant un insert de coupe (20). L'insert de coupe (20) est amené au contact d'une pièce à usiner pour enlever un copeau ou tournure de métal de la pièce à usiner. Le porte-outil (10) comprend des moyens à fluide de cassure des tournures pour envoyer un courant de fluide à haute vitesse sur la tournure qui est enlevée de la pièce à usiner afin de la casser en petits morceaux. La direction du courant de fluide peut être réglée de sorte qu'un seul outil peut être utilisé pour effectuer une variété de coupes tout en optimalisant l'efficacité du courant de fluide de cassure des tournures, et ce pour chaque opération de coupe.
Abstract:
On décrit un ensemble de verrouillage à bille pourvu d'une tête coupante (22) et un élément de verrouillage (24) comportant une tige (94) supportant au moins un élément de blocage (105). Un ensemble de positionnement (50) se connecte en fonctionnement à la tige de verrouillage de façon à ce que l'on puisse déplacer la tige d'une position verrouillée à une position déverrouillée. En position verrouillée, l'élément de blocage vient en contact avec la tête coupante pour la maintenir contre l'élément de verrouillage. En position déverrouillée, l'élément de verrouillage ne vient pas en contact avec la tête coupante de sorte que celle-ci n'est pas maintenue contre l'élément de verrouillage.
Abstract:
Un ensemble outil comporte un porte-outil (50) et un porte-plaquette (12). Le porte-outil comporte un passage de fluide (92) présentant une sortie (93). Un passage de fluide (104) ménagé dans la queue (14) du porte-plaquette possède une admission (102) renfermant un évidement peu profond (99) configuré pour maintenir la communication fluidique sur toute une plage de mouvement relatif du porte-outil et du porte-plaquette. Le passage de fluide débouche dans un orifice de décharge (114) pour diriger un jet de fluide sur les copeaux enlevés de la pièce.
