Micro Hole Processing Method and Comparison

Comparison	Processing Method	Apply	Merit	Deficiency
Electrical discharge-drilling	Pulse spark discharge etching metal forming for workpiece	Suitable for processing complex workpieces	Unique advantages for machining thin-wall workpieces, deep and narrow grooves and micro machining	Electrical discharge machining has no advantage and long processing cycle for workpieces that can be machined by conventional machine tools
Laser puncturing	Melting and gasifying materials by irradiation of workpiece with high power density laser beam	Suitable for repeated drilling with large number and high density and processing in difficult-to-machine inclined surface materials	Quick, clear, glabrous hole outline	Hole depth and hole depth-to-diameter ratio are limited
Linear cutting	The same as the principle of electrical discharge	Suitable for machining low rigidity parts and small parts	Reduced cost and shortened production cycle without design and manufacture of molding tools	Cutting while gradually dissolving workpieces is not suitable for mass production
Etching perforated	Contact chemical solution during etching to dissolve corrosion	Sheet below 2 mm, especially for sheet below 0.5 mm	Easy to achieve flat parts, no burr, complex pattern, and short processing cycle, low cost	The thickness of the material is limited, too thick to be etched
