CFM Schiller specializes in systems that dampen vibrations in equipment—for example, test benches. In production, they are once again relying on expertise from Microstep Europe.

Since 2018, CFM Schiller has relied on a multifunctional 3D plasma cutting system from the MG series by Microstep for precise cuts. In 2024, the next logical step in this direction was taken. This refers to the investment in a second, larger system of the same Microstep series with an oxy-fuel torch—this time supplemented by a tube processing module, as reported further. Its processing area measures 9,500 × 2,500 millimeters (approx. 31 by 8 feet). The focus of this project was the processing of tubes for GRB-type air springs, which are considered a standard product for isolating system vibrations. Tubes with a diameter of 558 millimeters (approx. 22 inches) are processed, with inner and outer contours being cut and weld seam preparation being automated using a 3D plasma rotator for bevel cutting. The plasma power source is a Hifocus 280i from Kjellberg. Before the upgrade, this task could only be carried out by the specialists from Roetgen through multiple processing steps on various machines in different production areas. Now, everything can be completed with the new machine, while also improving process reliability. Exhaust gases are filtered out using a Donaldson system. The so-called ABP technology allows bevels to be worked on already manufactured components, supported by a laser scanner.

Sheet Metal Cutting Capability Expands Range of Offerings

In the current production operation, tube processing accounts for around ten percent of the total production, as further reported. Diameters between 30 and 70 millimeters (approx. 1.2 to 2.8 inches) can be processed, with semi-finished products allowed to be up to 9,000 millimeters (approx. 29.5 feet) in length. To optimize the utilization of the second system, the range of services was intentionally expanded to include contract cutting of sheet metal, which now accounts for about 40 percent of the production. Primarily classic structural steels like S355 are processed – supplemented by other materials such as pressure vessel steel P265 or CroMo steel—using the Microstep systems. The range extends from one to 150 millimeters (approx. 0.04 to 5.9 inches) in sheet thickness, as noted. Thinner materials are cut using plasma, while for thicknesses of about 40 to 50 millimeters (1.6 to 2 inches) and up, oxy-fuel cutting becomes the more efficient method. Additionally, there is an automatic drilling spindle that can carry out boreholes up to 40 millimeters (1.6 inches) in diameter and threads up to M30. The system is also suitable for countersinking. The decision for the second investment was driven not only by the comprehensive package offered by Microstep but also by the high quality of the cuts, which allow for tighter tolerance ranges. Added to this is the robust construction of the MG 3D plasma cutting system. It can be said that the first "Microstep" made CFM Schiller notably more independent and flexible. And with the second, tube processing has become more productive.
