OVERVIEW OF THE HIGHLIGHTS OF THE CNC PLASMA CUTTING MACHINE DRM
3D sheet processing – work area 9,500 x 4,500 mm
The sheet and dome cutting center of the DRM series at Schwarte enables flexible 3D processing of flat sheets on a work area of 9,500 x 4,500 mm. The machine features a state-of-the-art plasma source XPR300 from Hypertherm with OptiMix gas console.
Complex processing of tank ends with diameters from 500 mm to 4,500 mm
Thanks to the 120° 3D bevel head, which can be tilted on one side up to 120°, the DRM series allows flexible bevels and holes to be cut in the tank ends of various shapes. A special table for dome cutting allows processing of tank ends with diameters between 500 mm and 4,500 mm. The machine's bevel tool station has an extended Z-axis stroke for processing of a wide range of dome heights. For cutting of different types of domes, the fume extraction is ensured from above the cutting head as well as through slots in the dome cutting table.
120° 3D bevel head for 3D processing of sheets and domes
The integrated 3D bevel head allows to achieve bevel angles of up to 90° (and on other side up to 120°). The bevel equipment with endless rotation enables precise automated weld preparation not only on flat sheets, but also on tank ends – including trimming of domes and processing of the whole dome surface.
MicroStep's mScan technology for precise scanning and processing of tank ends
MicroStep's mScan technology ensures the highest precision and best cutting results: In combination with the 120° 3D bevel head and a laser scanner, Schwarte generates high-quality results and saves a great deal of rework. The system determines the 3D geometry of each dome, compares the real contour to the ideal contour, automatically compensates for production-related deviations and sets the cutting paths exactly.
Even easier to achieve accurate results with ABC in mCAM
An additional function has been integrated into MicroStep's 3D CAM software mCAM: The process-limiting angle deviation of the plasma arc is compensated for by MicroStep's ABC (Adaptive Bevel Compensation) function. This function is implemented in the bevel head controls as a standard. At Schwarte, the ABC function has been additionally connected with the CAM software mCAM – it allows bevel corrections to be applied in mCAM after the scanning process of a particular dome. The system then generates a program adapted to the real contour. A highly precise result is achieved with a few simple operations!
