Product Descriptions

The unique Sodick automatic electrode feeder (AEF) is standard enabling unmanned multiple electrode supply. The new optional automatic electrode feeder changer (AEF-C) allows continuous machining of thousands of holes. In addition, the automatic guide changer (LGC) supports processing holes of multiple sizes. The rotary table (A/B) and part probe options are available for further enhancement.

K4HL is equipped with a penetration detection function as standard. Since the penetration of hollow-shaped workpieces such as turbine blades is automatically detected and machining is stopped, unnecessary machining after penetration can be prevented and unnecessary machining feed can be eliminated, so machining time can be shortened. is. Ion-exchanged water (pure water) is used as the processing liquid, and it is compatible with jet specifications (spraying with a nozzle) as standard.

We have newly developed a "SPK power supply" specializing in fine hole machining. Optimal servo control enables high-speed, high-quality hole drilling for difficult-to-cut materials such as titanium alloys / nickel alloys in addition to iron / cemented carbide / copper / aluminum / brass. The automatic programming software "LN Assist" supports program creation with simple operations using an interactive input method. Continuous machining of multiple holes, including the operation of optional devices such as AEF-C, ATC, and LGC, can be easily programmed.
