Introduction to Sodick EDM

Sodick EDM is a kind of high-precision slow-wire wire-cutting machine tool produced by Japan Shadick Company, and the following is its relevant introduction:

I. Technical specifications

Adopting non-resistance and anti-electrolysis power supply, with water immersion processing and taper cutting function. The highest practical processing efficiency of 120-150mm²/min, the best surface roughness of Ra <0.5μm, cutting accuracy of ± 0.005mm, generally using more than 0.15mm copper wire cutting.

Second, the type of machine

There are three main models, AQ water cutter, AP oil and water machine and high precision EXC oil cutter.

Third, some models and parameters

ALN400QS: Z-axis travel 255mm, maximum cutting thickness 250mm, main machine weight 2200kg, maximum processing speed 3.3-60mm/min, surface roughness 0.19μm, electrode wire diameter range 0.10-0.30mm, table weight 500kg.

α-C400iB: table size 626mm × 441mm, bearing 500Kg, X-axis travel 400mm, Y-axis travel 300mm, Z-axis travel 255mm, inclination ± 30 ° / 80mm, taper travel U-axis ± 60mm, V-axis ± 60mm, cutting efficiency of 330mm ²/min, electrode wire diameter Ф0.10-Ф0.30mm. Wire travelling speed <15M/min, roughness Ra≤0.19μm.

Advantages

High precision: through the water cooling device to control the temperature, reduce the thermal deformation of the machine tool, the use of linear motors to achieve precision positioning, can reach 0.1μm equivalent control.

Good surface quality: it can achieve good surface roughness, such as Ra <0.5μm, high surface quality of the processed workpiece, reducing the subsequent processing procedures.

High degree of automation: with high-speed automatic threading AWF function, 10-second cycle, 0.10 fine wire can be automatically threaded, and has a variety of automatic programming, automatic tool setting, short circuit and broken wire processing and other functions.

High cutting efficiency: the practical processing efficiency is 100-120mm²/min, and the large productivity can reach 350mm²/min.
