Abstract
An electric discharge machining apparatus includes an air blower attached to a head thereof, and when a work pallet is to be taken away from a work chucking device in a machining vessel after completion of machining, the air blower blows air onto the work pallet on the work chucking device before the work pallet is carried away therefrom, so that a machining liquid deposited on the work pallet is blown off and cleared therefrom.
Claims3
An electric discharge machining apparatus comprising:
- a pallet position measuring unit for measuring a pallet position of a work pallet carried onto the work chucking device in the machining vessel by an automatic work exchanger which accompanies the electric discharge machining apparatus;
- wherein,
- when a deviation between a pallet position measured by said pallet position measuring unit and a specified pallet position is not less than an allowable value, said automatic work exchanger carries away the work pallet from and carries it again onto said work chucking device.
An electric discharge machining apparatus comprising:
- a head for holding a machining electrode,
- a workpiece chucking device for positioning a workpiece pallet relative to said machining electrode,
- an air blower held by said head;
- wherein after completion of machining but before exchanging said workpiece pallet, said air blower operates to blow air onto said workpiece pallet to remove deposited machining fluid, and
- means for moving said head to plural air-blowing positions in accordance with the dimensions of said workpiece pallet.
