OVERVIEW OF THE HIGHLIGHTS OF THE PLASMA CUTTING MACHINE MG-PRSB 6001.20
3D sheet metal processing on a working area of 6,000 x 2,000 mm
AL-Cut AG opted for a plasma cutting system of the MG series for 3D processing of sheet metal on a working area of 6,000 x 2,000 mm.
3D processing of domes from 500 to 1,500 mm diameter
A special dome cutting table was installed at one end of the MG plasma cutting system. Thanks to the flexible design at the Swiss job shop center, the CNC cutting system enables 3D processing of domes with a diameter of 500 to 1,500 mm in addition to sheet metal processing.
Plasma rotator for weld edge preparation up to 45° and dome processing with automatic calibration unit
AL-Cut AG invested in a drilling plasma cutting solution for processing sheet metal and domes. The MicroStep plasma rotator for weld edge preparation up to 45° was integrated into the cutting solution. The endlessly rotating bevel unit enables V, X, Y or K seams to be applied and is used not only for cutting sheet metal but also for processing domes. The ACTG® calibration unit, developed and patented by MicroStep, is used to calibrate the bevel unit as well as the other tools. The unique system corrects inaccuracies and deviations fully automatically with the highest precision in the hundredth range. AL-Cut relies on an extremely powerful model from the HiFocus 600i neo series with automatic gas console and Contour Cut Speed technology as its plasma power source. According to manufacturer Kjellberg Finsterwalde, this model enables quality cuts on materials up to 120 mm thick and separation cuts up to 160 mm thick.
Drilling unit for drilling up to 40 mm and tapping up to M33 with automatic tool changer
For the processing of cutting tasks, a drilling spindle with 26.8 kW for drilling up to Ø 40 mm and threads up to M33 was installed at the MG plasma cutting system. Part of the drilling-cutting system is a magazine consisting of two tool carriers for a total of 16 tools. The system allows the tools to be changed fully automatically.
ABP® technology from MicroStep for subsequent weld edge preparation on already cut components
MicroStep's ABP® (Additional Beveling Process) technology was developed to realize the subsequent application of bevels for weld edge preparation on a cutting system. By means of the multifunction laser scanner, which is also used for the 3D detection of domes (see feature below), already cut components are scanned and flexible bevels are applied. This eliminates the need for time-consuming material handling on an additional (robot) workstation and makes it possible to apply weld edge preparations subsequently, even for thicker materials.
mSCAN® technology from MicroStep for precise detection and processing of domes
AL-Cut AG relies on MicroStep's mSCAN® technology for high-precision processing of domes. A laser scanner was integrated into the MG plasma cutting system, which determines the surface of the dome. In the process, height, diameter, camber radius and corner radius of the dome are recorded. The geometry data is imported into the mSCAN® software, the system compensates for production-related deviations from the ideal contour, corrects the parameters based on the 3D scan and sets the cutting paths accordingly. The use of this technology thus leads to a significant improvement in the cutting quality during the processing of the workpieces. An additional Scanner Calibration Station is used to calibrate the scanner during the dome processing.
