The Ergo-Cut 3150 , manufactured with a stable, rigid portal design and equipped with a sophisticated linear guide system as well as a 5 axle CNC control system. Dynamic drives ensure positioning speeds of up to 30 meters/minute, with a guaranteed positioning accuracy of +/- 0.1 mm. The worktable is 3,000 x 1,500 mm (X/Y traveling axes).The work feeders can be adjusted between 10 and 8,000 mm/min, and therefore can be optimally adapted to the material to be cut and the material thickness.

The Kjellberg system HiFocus 160i, which has proven itself time and again in industrial use and also the the Hypertherm HPR series, is used as the plasma source.  The standard equipment includes two plasma torch replacement inserts. Furthermore, the standard delivery also includes the automatic height adjustment of the plasma torch, the hose set for plasma, an automatic gas mixing system as well as the screw fittings and manometers for the gas tanks. The Kjellberg- and also the Hyperthermsystem has been successfully utilized in the Boschert CombiCut combination punch machines for many years and is distinguished by an outstanding cost/benefit ratio as well as reproducible cutting quality with regard to contour accuracy and edge surfaces. With the new HF 3015-160i flatbed plasma cutting system, normal steel of thicknesses between 0.5 and 8 mm can be cut in the „HiFocus Quality“ mode, while normal steel in thicknesses between 4.0 and 50 mm, stainless steel and aluminum in thicknesses between 1.0 and 35 mm can be cut in the „HiFocus plus“ mode, precisely, economically and efficiently.

The cutting quality is comparable to that of laser cutting in construction steel, high-alloy steel or aluminum of thicknesses between 0.5 and 35 mm. (Cutting quality as per DIN EN ISO 9013; cutting tolerance +/- 0.2 mm for normal steel of thicknesses up to 5 mm). The cut edges and surfaces are metallic blank and free of burrs, so that expensive rework is generally unnecessary. The flatbed plasma cutting machine is equipped with a CNC track control, which was designed especially for plasma cutting.

The screen control with operator guidance and graphics can be easily programmed, facilitating extremely short production times, even for individual parts and small series. The automatic referencing process as well as the automatic height control (tension-dependent height control…) ensure outstanding reproducibility of the cutting results. Boschert supplies the machine as a complete system ready for operation, and offers a series of accompanying accessories and suction units.

Rounding Machines RME

Ideal for thin materials!

Three rolls offer best results on rounding light gauge materials. The drive is connected to a motor with 1-phase power supply (household plug). The variable speed can be adjusted from 0 to 12 m/min. A counter displays the rear roll rounding setting. The 2 pedal footswitch is used for forward or reverse motion. An all round ripcord meets the safety requirements. In order to achieve perfect curves, the rolls are crowned and optionally hardened.

Specialized on air ducts!

NEW:

The RAS VENTIrounder is now also available with even rear rounding rings. This allows rounding outside duct cheeks without scratching the visible material surface.

The application: Air ducts

The RAS VENTIrounder for the air duct production solves all these problems. It easily rounds sheet metal elbow cheeks with pre-formed Snap Lock or Pittsburgh seams. The result are perfectly rounded inside and outside elbow cheeks.

The starting situation

The production elbow parts for air ducts starts with a rollforming process. This operation seams the blank and creates one part for the lock. This happens usually on a lockforming machine, for instance the RAS SpeedySeamer. In the second step the internal and outside elbow duct cheeks will be rounded on the requested radius.

Here a rounding machine comes into play. Traditional rounding machines use one part rolls. Since the part comes with the rollformed seam, traditional rounding machines can offer only some poor and costly compromises. Setting the rolls to the seam thickness results in poor radii. Stronger settings will damage the seam and in the long term also the rolls. Two remedies are known. Inserted metal strips, keep the seam open but must be manufactured separately and often can be used just once. Reusable mats must be produced also separately and need to be adjusted to the width of the elbow cheek.

The operation

After having moved the rounding rings along the working length and set them to the approximate blank width, you can start rounding the blank. The rings round the sheet metal without touching the seams. Therefore the seams keep their geometry during the rounding process. A gear-brake motor with variable speed drives all three shafts and can be operated from a single phase outlet. The rear shaft can be set with a hand wheel for the adjustment of the bending radius.
