Vollmer VPulse  wire erosion tools to keep your finger on the pulse

The new wire erosion machine from VOLLMER, the Swabian sharpening specialists, is called the VPulse 500. The VPulse 500 is not just the successor to the tried and tested QWD series; it is also equipped with a new erosion generator and the most advanced technology.

Using this machine, PCD (polycrystalline diamond)-tipped tools can be produced quickly and precisely in large quantities. Modern machine kinematics ensure high profile accuracy in both production and maintenance. VOLLMER's operating concept for the VPulse 500 is designed around intuition. The touchscreen acts as a highly developed human-machine interface that simplifies programming and control to guarantee quick, error-free operation.

With the VPulse 500 wire erosion machine, VOLLMER has begun a new chapter in its long history of eroding tools. For a quarter of a century, the Biberach sharpening specialist has been developing erosion machines with designations beginning with Q. But V is now the new Q. The VPulse 500 is the successor to the QWD machines and comes as standard with technology that enables high-quality PCD-tipped tools to be manufactured at incredibly high productivity levels, whether for production or servicing. The human-machine interface has an adjustable control panel that includes a touchscreen, offers user-friendly menu navigation and intuitive operation.

This means that even complex tasks can be carried out after a short training period. The PCD tools are measured and eroded in one clamping process in which simultaneous path interpolation along five CNC axes guarantees that milling cutters, drills and multi-stage tools are machined precisely. The machining process has the option to be carried out with unsupported clamping or with a counter point unit for the machining between the tool centers.

The beating heart of the new VPulse 500 is the Vpulse EDM generator technology. This newly developed high-performance generator ensures higher stock removal rates or improved surface quality. As is the case for the previous QWD machines, the eroding wire for the VPulse 500 also functions as an electrode. The wire is guided close enough to the workpiece that a spark is generated between the electrode and the workpiece and removes the material from the PCD-tipped cutting edge. Thanks to the fine eroding wire, complex geometries and the smallest inner radii that are commonplace on multi-stage tools and bell-shaped tools can be machined precisely.

The VPulse 500 integrated technology database simplifies and improves the handling of pre-configured parameters with its user-friendliness that allows material-specific machining programs to be selected in no time. Depending on the requirements of the tool manufacturer, the technology database can be added to individually. Intelligent automation solutions allow the wire erosion machines to be operated on a multi-shift basis, or in unmanned operation at weekends. Workpiece storage for the VPulse 500 is available for 16, 28 and 65 workpieces. PCD tools weighing up to 25 kilograms can be machined using the VOLLMER machine. Workpieces with a length of up to 500mm and a diameter of up to 320mm can be accommodated in the work envelope.

"The VPulse 500 marks the beginning of a new era of wire erosion for us not only in terms of technology and applications, but also in our naming style," states Dr.-Ing. Stefan Brand, CEO of the VOLLMER Group. "The V stands for VOLLMER and the second part of the name describes the technology. 'Pulse' refers to the generator technology which is used in the VPulse 500 and sets a faster pace for the erosion process."
