CNC WEST June/July 2018 www.CNC-West.com 67 New Products The machine uses the company’s pick-up concept, where the main spindle is used to load and unload workpieces from the integrated con- veyor belt or shuttle. Users can equip the machining area with a variety of turning and grinding modules. The first step is to pre- or complete- machine component surfaces that can be hard turned. Then, without changing the setup, the machine finish grinds areas that require high-precision geometries. This process has two advantages: the turning process is faster than grinding flat surfaces and using the grinding tools for only fin- ish grinding operations reduces wear and tear, the company says. Because the workpiece is machined in a single setup Ewag reports that the process is more efficient than when carried out on two machines. The machine can be used as a conventional vertical grinding center, equipped with two grinding spindles for external and internal grinding, or for combination machining, with an additional block toolholder for hard turning operations. It can be equipped with corundum or CBN grinding technology, and users can dress vitrified-bonded CBN grinding wheels using a rotating diamond roll.A structure-borne sound system serves as GAP-control between the dressing roll and grinding wheel. An adaptive pro- cess control system promotes shorter cycle times. New Whisperline Turning Boring Bars—Iscar Deep boring applications are of- ten accompanied by strong unwanted vibrations. Iscar’s new Whisperline offers a new solution for overcoming chatter and vibrations. The boring bars feature a unique integral absorber which Iscar reports suppresses cutting tool vibrations. The absorber mecha- nism provides optimal surface finish and a soundless turning application. The boring bars are available up to 10 x D length bars. This new tool line is supplemented with a variety of exchangeable heads for turning, threading and grooving.
