Electro-spark hardening machine
XKS-350 Electro-spark hardening machine
Main specification:
Weight:15KG
Coating Thickness:60µm
Max.degree of smooth:∨5
Perforation Diameter:φ1~22
Power:350W
External Dimention:400*295*180mm
Applications:
1.EDM electrodes are made of carbide.Increase the surface of ferrous metal up to HV1100-1400 (HRC70-72 °). Increase the wear resistance, and corrosion resistance, extend usage life 1-3 times.
Mainly for surface hardening, like cold stamping, forging & pressing, bending, extrusion, stretching, die-casting moulds.
2. Processing those easy abrasion parts like high speed steel cutter, tongs, mechanical parts; and also can be used in micro repairing to abrasion parts.
3. Sandblasting to various plastic mould, rubber mould.
4.Dimension repair: the thickness of surface may increase by 20-60mm after hardening; therefore it can be applied to hardening and repairing abrasion part of moulds, cutters and tongs.
5.Extract broken tap, bolts, drill..etc in metal work pieces.

Characteristic of XKS-350 hardening machine:
1. Portable power, portal type, easy to carry and operate in various environment.
2. Copper/ brass pipe or rod: use brass tube or copper rod as electrode.
3. Use water as operating fluid.
4. Big work pieces: easy to process broken screws from big work pieces.
5. Automatic operating, no need occupy labors energy.
6. Use electrical erosion remove principle, no need contact work pieces; no force in processing, and no damage to work pieces.
7. Magnetic base, processing devices can suck to the surface of work pieces.
8. The electrode head can be adjusted freely in different angle.

Main function:
1. Single-phase 220V power
2. Portable & easy to operate and carry.
3. Automatically control the processing depth.
4. Working pump is attached in the machine.

XKS-350 hardening machine processing effect:
1. Processing any broken parts & screws over Φ 2 .
2. Processing speed:

Screw diameter	Processing length	Time	Electrode diameter
M3	10m	5min	¢3
M5	10m	12min	¢5
