Intro

Electro-Spark·Welding machine

DEPO Series

The use of EDM (EDM) principle of surfacing and coating equipment

According to the principle of discharge will be soluble electrode infiltration, the accumulation of the workpiece surface coating, surfacing machine

Spotlight :

  • It is miniaturized and lightweight based on SparkDepo
  • It is environmentally friendly machines, mold, mechanical parts, tooling and other preventive protection and repair, can save resources, but also to protect the environment.

It is miniaturized and lightweight based on SparkDepo

This model is Japan original install big power model.Simple operation, high quality of coating and surfacing

It is miniaturized and lightweight based on large ESD

To achieve localization based on the Japanese original installation.The price of the machine has been greatly reduced

Depo series of principles

After the capacitor in the host is fully charged, the temperature of the contact between the fused electrode and the workpiece reaches 8,000 to 25,000 ° C in the period of 10-3 to 10-1 seconds and the ultra short pulse width of 10-6 to 10-5 seconds C, in the plasma state fused electrode infiltration to the workpiece surface, resulting in alloying, resulting in a combination of high strength.

Processing site diagram

Coating and surfacing layers

  • Wearproof
  • Heatproof
  • Resistant to burning
  • Anti-corrosion
  • Oxidation-resistivity
  • Lubricant
  • Clamping

Low heat input

As the discharge time (pulse width) is short, the intermittent time is long, the heat of the processing site is sufficiently diffused, so the heat input is low.

  • St discharge time : 10-6~10-5s
  • It interval : 10-3~10-1s
  • Output : Current when surfacing or coating

Features

High performance

  • 1. Low heat input, no internal stress, deformation, undercut, stomata and other defects.
  • 2. The surface of the workpiece to form a strong diffusion layer, combined with high strength.
  • 3. Through the parameter adjustment, can control the surfacing layer or coating thickness and surface roughness.
  • 4. Through high-power surfacing or coating, you can get a thicker surfacing layer or coating and the deeper diffusion layer, the service life has been greatly improved.
  • 5. Depending on the purpose, different welding torches can be used. With argon protection, can prevent oxidation, resulting in high-quality coating and surfacing layer.

safety

  • 1. Simple operation.
  • 2. No noise, no dust, no waste liquid, no light, no smell and other issues.
  • 3. Just wear UV protection glasses such a simple tool can work.
  • 4. Adequate dual safety circuit protection, improve the safety of the machine.

Extensive application

  • 1. The machine is easy to carry, not subject to site restrictions.
  • 2. Large parts without demolition, can be directly on the required parts for processing.
  • 3. No need to warm up and insulation, greatly improve the efficiency.
  • 4. The amount of surfacing can be controlled below 0.1 mm, shortening the finishing time.
  • 5. Even if the processing site is worn, in the same part can also be processed several times.

other Infor about Depo

1High Bonding Strength

The fusible electrode is deposited to the workpiece while a strong diffusion layer is formed on the surface of the workpiece. So the combination of high strength.

2Applicable substrate

It is suitable for low carbon steel, medium carbon steel, tool steel, die steel, cast iron, cast steel, stainless steel, aluminum alloy, nickel copper mold and almost all electric conductors.

3Alternative Machining Methods

Electroplating, spraying, CVD, PVD, TD treatment, nitriding, carburizing, quenching, welding and so on.
