Portable EDM machine
Features:
1.Protable EDM machine can fast remove broken taps, drill, drift, etc., without damaging to the work piece. What applies a magnetic base and a cross stand to support the head, it can be placed at any position, adjust the processing direction comprehensively. It can be applied on any size of work-pieces, especially effective for large machine tools.
2.The short hole processing speed is about 1mm/min.
3.The work head with vibration function.

Product Description:
Working principle
Use workpiece and electrode contact broken tap from short-circuit spark, corrosion broken tap, remove broken tap bit by bit.
Application
1.Remove broken in workpiece diameter tap, drill, reamer, tools/tools such as screw, plug gauge;
2.Can be working in any size, shape of workpieces.
3.Various angles, different shapes from surface of electrodes, processing multiple holes.
4.Processing no precision requirement hole.
5.Especially suitable for difficult to processing large workpieces in EDM machine.
