The principle of electric spark drilling machine

1, the working principle of the EDM perforating machine is the use of continuous up and down vertical movement of fine metal copper tube as the electrode, stainless steel, hardened steel, carbide, copper, aluminum and other metal workpieces for the impulse spark discharge etching molding. Fine hole piercing machine can be used for processing engine cooling holes, sieve plate group holes, hydraulic and pneumatic components of the oil circuit holes, nozzle oil pump oil injection holes, chemical weaving spinneret spinneret holes, wire cutting threading holes, and other traditional machining methods are difficult to process a variety of small holes in the depth of the process.

2, EDM hole punching machine according to the application of different media is broadly divided into two kinds, one is the liquid EDM hole punching machine, due to the liquid processing through the copper rod hole, may be clogged with copper rod hole, so the minimum can be processed 0.15mm hole! Depth can only be processed 20mm. is commonly used, the other is a gas EDM hole punching machine, through the copper rod hole in the medium used is gas, so it is not easy to be clogged, can be processed more precise small holes.

3, punching machine is by the four major parts of the interactions to complete the punching process. First of all, the material will move to the automatic punching machine camera scanning area, the camera scans the image after processing and give the control part of the signal, the control part of the signal received, further processing and control the transmission part of the action, so that the punching head in the plane of the X-axis, Y-axis alignment, complete the alignment of the action of the pneumatic part of the beginning of the work of the solenoid valve to control the cylinder for punching action. Automatic punching machine to play printing positioning holes, the whole action in one fell swoop, fast, accurate and efficient.
