UNITED GRINDING has extended its line of WALTER EWAG technologies for cutting tool production to now include the LASER LINE ULTRA 5-axis machining center that incorporates ultra-short pulse laser technology. With this new tool-machining system, tool makers can efficiently meet increasing demands for high-precision CVD-diamond tooling needed to cut today's challenging materials such as lightweight carbon fiber (CFRP) and special aluminum alloys.

According to Ted Neckel, director of corporate marketing for UNITED GRINDING North America, EWAG placed high priority on application flexibility, quality and productivity in tool machining when developing the LASER LINE ULTRA. "Cutting hard diamond tooling materials places limits on present-day grinding and eroding technologies. The addition of laser technology to our portfolio gives customers a multitude of new application options."

The LASER LINE ULTRA production center uses a unique kinematic concept that combines a 5-axis machine kinematic system (X/Y/Z/B/C) with superimposed 3-axis laser beam guidance (U/V/W). The design allows toolmakers to laser machine a tool's cutting edges as well as laser ablate its complex step chipbreakers in one machine clamping. The ultra-short pulse laser technology directly vaporizes materials without significant heat input and without comprising their integrity.

The machine offers an X/Y/Z travel of 15.74" x 7.09" x 5.91" (400 x 180 x 150mm) and a high-precision tool holding fixture (C-axis) that can be equipped with mechanical or vacuum clamping systems for plate-shaped tools. The C-axis is also available with a fully automatic HSK63 interface for processing rotary tools with maximum cutting diameters up to 5.91" (150mm).

EWAG encapsulates and protects the LASER LINE ULTRA's fully integrated 50 high-power picosecond laser beam path so as to protect it from external influences. The laser source and relevant optical elements are integrated into the system's water-cooling circuit and guarantee the highest possible process stability.

An integrated extraction unit extracts laser vapors and flue gases into and through a filter system. An integrated 6-axis articulated-arm robot with triple gripper head automatically loads the LASER LINE ULTRA for autonomous production. The machine's robot cell comes standard equipped with two pallets.

The entire LASER LINE ULTRA system only requires 16.4 square feet (5 square meters) of floor space, making it the most compact high-end laser production center available for processing super hard diamond cutting tools.

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • aluminum alloys

    aluminum alloys

    Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.

  • fixture

    fixture

    Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.

  • grinding

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • machining center

    machining center

    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
