characteristics and applications of electric discharge machining
Electric Discharge Machining (EDM) is a machining process that uses electrical sparks to erode the parts. It is a highly accurate and precise method of machining that is used to create complex shapes and intricate details in a wide variety of materials. EDM is used in a variety of industries, including aerospace, automotive, medical, and electronics.
1.First benefit of cnc edm machine.the electrode tool is not contact with the workpiece materials when it machining,there is almost no mechanical force between the two sides.Therefore,the electric discharge machining has no relationship with the hardness of the electrode and workpiece material.e.g.the graphite or copper electrode can machine the quenched steel,carbide,even diamond.
2.Fine processing,because the energy density of pulse power could be precisely cotrolled,and no mechanical force between the two,The precise and fine machining can be acheived.for example,the narrow slit,narrow groove and micro holes machining,those accuracy can acheive to micron order.
3.contour machining,electric discharge machining that’s easy to acheive the automation and intelligentize.the application for the intelligent software make the contour machining more precise.
4.the edm machine can reduce the machining processes and working hours,easy to maintain and operate that make employee lower the work intensity.
At present,the technology of the edm machine is widely used in aviation,electronic,mold manufacture,instrument and meter,motor and electric appliance,precision machinery,vehile,military industry,and scientific research department.
The electric discharge machining applications as follow
1.machining various of metals and alloy materials,conductive hard materials e.g. PCD,CBN,and cermet,special thermal sensitive material,semiconductor and non-semiconductor.
2.variuos of complex cavity and hole workpieces,including circular hole,square hole,polygonal pore,micro hole,deep holes etc.various of cavities.
3.cutting various workpiecs and parts,cutting micro narrow slit and parts,tools,measuring tool,screw shape parts.
4.product surface strengthening,e.g.metal surface quenching,electric discharge machining can remove the broken screw,drill bit or machine taps in hole of the products
Overall, EDM is a highly accurate and precise machining process that is used to create complex shapes and intricate details in a wide variety of materials. It is a cost-effective process that requires minimal setup time and can be used to produce parts in large quantities. EDM is used in a variety of industries and applications, making it a versatile and valuable machining process.
