Machining Center Offers Turning, Thread Generation
IMTS 2018: Starrag’s Heckert DBF 630 six-axis machining center enables turning, milling, boring, drilling and thread generation operations in one setup.
Starrag’s Heckert DBF 630 six-axis machining center enables turning, milling, boring, drilling and thread generation operations in one setup. The machine is said to be particularly useful for oil and gas industry parts such as fluid ends, gate valves, drill bits and pump housings.
The center features a B-over-A trunnion table and a 45-kW (60-horsepower) U-axis head with 1,700 Nm (1,254 ft/lbs) of torque. To consolidate machining operations, the head consists of a faceplate with integrated work spindle and CNC radial facing slide.In addition to external, internal and face turning, the head enables conical and contour turning courtesy of the radial-facing slide’s NC axis. For turning on a fixed workpiece, the rotating turning tool, which has an axial runout of 5 to 6 µm, can be adjusted by ±35 mm.Other features include
a 40-tool automatic tool changer and pallets measuring 630 × 630 mm that can accommodate loads as heavy as 1,000 kg.
When this aerospace job shop settled on machining tungsten alloys and other heavy metals as its specialty, it had to have a machine tool, cutting tools, workholding and process know-how to succeed.
Instead of inspecting machined parts, get to know the process better.
Large monolithic aircraft parts may be machined more productively one at a time instead of three at once.
