The Microstep PLS 7501.25PG is a used plasma cutting machine — sometimes referred to as a CNC plasma cutter — manufactured in 2008 and currently located in Germany. Plasma cutting machines use a high-velocity jet of ionised gas to cut through electrically conductive materials with precision, and are widely employed in metal fabrication, structural steelwork, and industrial manufacturing. Microstep is a well-established European manufacturer specialising in CNC cutting systems, including plasma, flame, and laser cutting equipment, serving industries that demand accurate, high-throughput sheet and plate processing.
This is a 3-axis, single-portal machine equipped with two cutting tools: a Hypertherm HPR 260 AGC plasma unit with a maximum piercing and cutting capacity of 58 mm, and an acetylene gas burner fitted with a gas rotator. A BEM 12 drilling head is also included. The dual cutting configuration allows operators to handle a broad range of materials and thicknesses from a single machine, with the acetylene burner suited to heavier plate work and the plasma unit covering high-definition cuts across the full material range. Maximum cutting thickness is stated at 50 mm.
The working field is substantial, with a longitudinal movement of 7,500 mm, a cross movement of 2,500 mm, and a maximum working zone of 4,000 mm wide by 35,000 mm long. Vertical travel is 150 mm for the plasma axis and 200 mm for the gas axis, including the rotator. The BEM 12 drilling head has a vertical travel of 80 mm. Working speed ranges from 0 to 100 mm/s across all axes.
Accuracy specifications include a maximum longitudinal deviation of 0.5 mm over 3,000 mm and a maximum cross deviation of 0.5 mm over 2,500 mm. The machine runs on a Microstep MSNC500 control system. Drive units are supplied by Control Techniques: the longitudinal axis uses two DCM 6C 30/14 A1 drives, the cross axis two DCM 3B 35/06 A1 drives, and the vertical axes two DCM 2C 30/03 B1 drives. Gear ratios are 14.81 mm/rev on the longitudinal axis (belt drive), 13.33 mm/rev on the cross axis (belt drive), and 2 mm/rev on the vertical axis (belt and screw). The mechanical enclosure is rated IP 43.
Specified operating conditions include an ambient temperature range of 5–40 °C, maximum relative humidity of 90% at 20 °C, atmospheric pressure of 84–107 kPa, and a maximum dust concentration of 200 mg/m³, classifying the environment as common type under STN 330300 with the N32 operational temperature exception. The machine has an overall depth of 10,169 mm.
