The productivity benefits that oil and gas companies can gain by using Starrag’s Heckert DBF horizontal machining centres are unquestionable – thanks to the machines’ integral U axis that carries the Starrag DBF multi-tasking head, the rewards for one-hit, multi-facet, multi-face machining are unrivalled!
The DBF spindle head comprises an integrated work spindle with CNC radial facing slide for the U-axis travel. For turning on a fixed workpiece, the rotating turning tool – which has an axial runout of just five/six microns - can be radially adjusted by +/- 35 mm. In addition to external, internal and face turning, the head also permits conical and contour turning courtesy of the radial facing slide’s NC axis. Unlike other U-axis tools add on units, the DBF provides 1,200 rpm, 45 kW of continuous power, and 1,700 Nm of continuous torque allowing the U-axis to efficiently rough and finish features with a superior degree of accuracy.
For milling and drilling, the work spindle is arranged in the U-axis central position and is capable of delivery 3,500 rpm, 45 kW of continuous power, and 1,700 mm continuous torque. This allows the machine to perform effectively as a horizontal machining centre for roughing and finishing when the U-axis is not required.
