Cutting tool manufacturers have always had the inconvenience of producing solid-carbide and PCD cutting tools on two separate machines. However, Vollmer has eradicated this issue with its versatile new VHybrid 260 solution that can grind carbide tools and erode PCD tools on a single platform.

Importantly, the VHybrid 260 allows users to switch between grinding and erosion processes in next to no time. Utilising Vollmer’s proprietary multi-layered machining technology (first proven in the company’s Vgrind series), the vertical alignment of two spindles allows the grinding and electrode wheelsets to pivot the C axis and ensure operators always achieve optimal results. This configuration allows users to combine both processes. If the tool requires both grinding and erosion, the VHybrid 260 can create one complete and efficient machining process for all tool production requirements.

The multi-layered spindle configuration allows the grinding of carbide tools with diameters of up to 150 mm on the top spindle, whereas the bottom spindle can accommodate both grinding and erosion. Here, the finely tuned Vpulse EDM erosion generator delivers surface finishes to a roughness of 0.1 μRa.

Vollmer has factored automation and ease of use into every element of the VHybrid 260, including the tool loading and unloading facilities. Here, Vollmer offers several options with its HC4 chain magazine that has space for 39 HSK-63A tools or up to 158 shank-type tools with a maximum weight of 5 kg. Alternatively, for manufacturers producing larger tools, Vollmer offers the HC4 Plus, which provides space for 160 shank type tools or 40 HSK-63A tool holders with a tool diameter of 80 mm. With larger tool diameters of up to 150 mm, there is space for 20 HSK-63A tool holders with a maximum weight for individual tools up to 10 kg.
