MICRO EDM

Features:

A pore (processing range pore diameter of 0.03 to 0.15 mm and diameter thickness ratio of not less than 1:7) is processed on the metallic material structure surface.

Combination of a visual system and a servo alignment platform (X/Y /R axis) at the product position can be completed automatically.

The thickness of the holes is automatically inspected online.Applications:

The ceramic ESD-safe nozzle tip is ideal for use in electronics manufacturing, particularly in dispensing systems for die bonding processes.

It can also be used in other industries where precision and protection from electrostatic discharge are necessary.

Benefits

Micro EDM is a non-contact machining process, and there are Merritt, such as micro cutting force and hard material processing, and with the development of several decades, micro EDM processing now has high technology level, micro energy pulse power supply, micro feed system, servo control system, etc .

The digital control system was developed by applying micro EDM.

The surface roughness Ra of micro EDM processing can be achieved up to 0.2 um, and the maximum processing accuracy can be attained to 440km in the processing of microcavities or small structures, and it is satisfied with the machining requirements of micro holes and fine molds.

Micro EDM processing drum is made of fine tungsten wire or alloy wire. During processing, a micro energy pulse power supply and a dedicated EDM engine oil are added between the tool electrode and the workpiece, and the digital control axis (micro feed system) performs linear servo operation in accordance with the inspection information in the processing state by the control of the digital control system.

After passing through the liquid medium between the tool electrode and the workpiece, a spark puzzle discharge is formed, the temperature is instantaneously elevated in the spark passage, and the portion of the metal of the surface of the workpiece is melted and vapor.

Cooling effect of liquid medium spark mechanical oil causes minute etching granules. The granules are quickly discharged from the processing area by the flow of the mechanical oil, and finally the purpose of etching the metal.
