This Koike PNC-12 Extreme is a used plasma cutting machine — sometimes referred to as a plasma cutter or CNC plasma table — designed to cut metal plate and sheet material with precision using a high-temperature plasma arc. Koike is a well-established Japanese manufacturer with a long history of producing cutting and welding equipment for fabrication, shipbuilding, steel construction, and related industries. This example was built in 2015 and is located in Germany.
The machine operates across two axes and offers an effective cutting area of 1,500 × 3,000 mm, accommodating a broad range of plate sizes. Maximum cutting thickness reaches 50 mm, while the recommended cutting range is 1–20 mm with a maximum of 40 mm achievable under standard conditions. Piercing thickness is rated up to 20 mm. Rapid travel speed is 4,000 mm/min and maximum cutting speed is 3,000 mm/min. The X and Y axes are driven by stepping motors via rack-and-pinion drives with linear guides, and the torch lifter uses a DC motor. The torch holder accepts a 35 mm diameter torch, and the system includes initial torch height control, arc voltage height control (switchable between 1:1 and 50:1 ratios), and torch collision protection.
Control is handled by a Koike D420 CNC unit featuring a 7-inch colour multilingual display. The control supports rotation, mirroring, nesting, recovery, and piercing point selection. Data input is via USB or manual data input (MDI), and the program format is EIA. CAD files can be imported in DXF and DWG formats, and the system includes 47 preinstalled cutting patterns along with automatic nesting and sequencing. The included software package comprises Koike PNC-CAM Expert V2E together with a FastCAM licence.
The plasma source is a Kjellberg CutFire 100i, a 100 A air-cooled unit with a 100% duty cycle at full output. Cutting current is adjustable from 35 to 100 A. The unit draws 16.6 kVA from a three-phase 400 V ±10%, 50 Hz supply, with an open circuit voltage of 330 V DC, an efficiency of 0.92, and a power factor of 0.97. Cooling is provided by a built-in fan and torch gas cooling. The gas supply requires compressed air at 5.5 bar and 220 Nl/min. The plasma source carries an IP21 protection rating, weighs 50 kg, and measures 710 × 280 × 590 mm. The control unit is powered separately from a single-phase 200–240 V, 50/60 Hz supply.
This listing includes a substantial package of ancillary equipment alongside the cutting machine and plasma source: a laptop with FastCAM licence, a plasma table measuring 3,000 × 1,500 mm with four suction chambers, a ventilation unit with outlets, a 500 kg capacity hoist, a 5.5 kW piston compressor with a 270-litre vessel rated to 10 bar, a 1,500 Nl/min air dryer, a lifting magnet and sheet gripper, and a stock of nozzles, electrodes, and spare parts.
