Abstract
Vertically divided reticulated cage 20 is provided for receiving machined chips 2. A lower cage 21 is fitted into a lower guide 11 or a nozzle 14, and the lower cage 21 is detachably mounted thereto. An upper cage 22 is mounted to an upper guide 10 or a nozzle 13. During machining, the upper and lower cages 21 and 22 are brought into close contact with each other, and an electric discharge machining portion is surrounded by the cage 20. A work piece 1 and a clamp member 5 can move relatively with respect to the cage 22 and a wire electrode 12 by a notch 22a formed in the upper cage 22.
Claims9
A wire electrical discharge machine in which voltage is applied between a stretched wire electrode and a work piece, machining liquid in injected between the wire electrode and the work piece, electricity is discharged between said wire electrode and said work piece while moving said wire electrode relative to said work piece, thereby machining said work piece to form machined chips, wherein
- receiving means for receiving said machined chips, which covers at least a portion lower than, or both lower than and a side of, the portion where electric discharge machining is carried out, is disposed,
- said receiving means preventing said machined chips from passing through and allowing to said machining liquid to pass through.
A wire electrical discharge machine comprising an upper nozzle disposed above a work piece and lower nozzle disposed below said work piece, in which a wire electrode is inserted between said upper nozzle and said lower nozzle, and said wire electrode moves relative to said work place to machine said work piece, thereby forming machined chips, wherein
- lower receiving means for receiving said machined chips are provided to at least said lower nozzle or a lower guide to which said lower nozzle is mounted
- said lower receiving means preventing said machined chips from passing through and allowing machining liquid to pass through.
A wire electrical discharge machine in which a wire nozzle and a wire guide are disposed laterally in a horizontal direction,
- a wire electrode horizontally held by said wire guide moves relative to a vertically clamped work piece to machine said work piece, thereby generating machined chips, wherein
- receiving means for receiving machined chips is mounted to said wire nozzle or said wire guide,
- said receiving means preventing said machined chips from passing therethrough and allowing machining liquid to pass therethrough.
