[0005] However, such a conventional fine-hole electric discharge machine is arranged side by side with respect to the wire electric discharge machine at the same time, and is used to drive the slider device and the electrode of the tube electrode for electric discharge machining of small holes such as initial holes on the workpiece. The conveying device and the servo function are set separately from the slider device, the wire electrode supply device and the servo function used to drive and supply the upper wire head for the wire electrode provided on the wire electric discharge machine.
Therefore, the existing fine-hole electric discharge machine has a large-scale device structure and high cost.

Embodiment Construction
[0020] Hereinafter, an embodiment of a fine hole electrical discharge machining device detachable to a wire electrical discharge machining machine according to the present invention will be described with reference to the drawings.
[0021] This fine-hole electric discharge machining device is a device for electric discharge machining an initial hole as a small hole 50 through which a wire as a wire electrode 30 can pass through a workpiece 1, and is a simple type that can be detachably mounted on a wire electric discharge machine. structure. The wire electric discharge machine sets the workpiece 1 on the workpiece mounting table 14, and the workpiece mounting table 14 is arranged on a worktable 51 that can move along the X-axis direction and the Y-axis direction (vertical and horizontal directions parallel to the paper surface). In order to discharge the workpiece 1 through the wire electrode 30, the wire electric discharge machine is equipped with: an upper head body 2 with ...

Disclosed is a pore electrical discharge device allowing easy installation and removal to a head 2 of a wire electrical discharge machine, without the use of an additional servo, having a simple construction and low manufacturing costs. The pore electrical discharge device is provided on a head 2 of an upper wire head 3 of a wire electrical discharge machine with a freely installed and removed pore head 10. A rotary spindle 33 is rotatably supported on the pore head 10 for removably mounting a pipe electrode 25. A guide holder 29 is provided to guide the pipe electrode 25 such that the pipe electrode 25 is movably supported by the pore head 10.
Description
technical field [0001] The present invention relates to a fine-hole electrical discharge machining device which is detachably mounted on a wire electrical discharge machining machine for performing electrical discharge machining of workpieces such as superhard alloy, hardened steel, copper, and stainless steel through wire electrodes, And the initial hole for electric discharge machining is machined on the workpiece through the tube electrode. Background technique [0002] In the past, the wire electric discharge machine used the part where the wire electrode travels to process workpieces such as cemented carbide and hardened steel. However, the workpiece to be subjected to wire electric discharge machining requires an initial hole for the wire electrode to be inserted first. A fine-hole electrical discharge machine is known as an initial hole machining device for performing initial hole machining. The fine-hole electrical discharge machining machine installs the holding de...
