The EDM drilling machine uses a hollow copper tube and liquid or gas passes through the thin hole to cool and remove chips. The discharge of the electrode and the metal generates high temperature to corrode the workpiece, which can be used to process superhard steel, hard alloy, copper, aluminum and any conductive substance.
EDM drilling machine can be roughly divided into two types, one is liquid perforation, and the other is gas perforation. Because liquid needs to pass through the pores, it may cause the pores to be blocked, so it can only process holes as small as 0.02mm. It can only process 0-300mm. Gas perforation Since the pores pass through the gas, it is not easy to be blocked, so tighter holes can be processed.
How EDM drilling machines work
There are many aliases for EDM drilling machine: EDM hole drilling machine, edm punching machine, edm small hole machine, and fine hole discharge machine. Its working principle is to perform pulse spark discharge on the workpiece to remove metal through the vertical movement of the electrode wire. , so as to process the workpiece required by the customer. The electrode of the piercing machine is a hollow copper rod, and the working fluid passes through the fine hole in the middle of the copper rod hole, mainly for cooling and chip removal. The high temperature is generated by the discharge between the electrode and the metal, thereby corroding the metal to achieve the purpose of perforation.
What is the difference between EDM hole drilling and EDM wire cutting
1. EDM hole drilling requires that the processed workpiece should have a cross section or shape, while WEDM moves along the electrode wire.
2. EDM hole drilling has only one relative servo feed movement, while EDM has two horizontal directions and relative servo feed movement at the same time.
Application of EDM drilling machine
EDM drilling machine has a wide range of applications and is used to process fine holes in superhard steel, hard alloy, copper, aluminum and any conductive material. The processing range is 0.02mm to 3mm aperture, and can process small holes with taper at the same time, so it is widely used in the precision mold processing industry, generally used as supporting equipment for wire electric discharge machine tools, for wire electric discharge cutting Processed threading hole, chemical fiber spinneret, spinneret hole of spinneret, filter plate, group holes of sieve plate, engine blade, cooling hole of cylinder body, oil circuit and air circuit hole of hydraulic and pneumatic valve body, etc.
