The VHybrid 360 offers a range of automatic settings that enable unmanned production around the clock. With the newly devised Vollmer tool manager, users can manage the automatic switching of up to eight grinding or eroding wheels intuitively.
VHybrid 360 is based on multi-layer machining, which is implemented through two vertically arranged spindles. Here, Vollmer is using the tried-and-tested technology of its VGrind grinding machine series. The bottom spindle can be used for both grinding and eroding, while the top spindle is reserved exclusively for grinding.
Vollmer’s key erosion component is the VPulse EDM erosion generator, while from a grinding perspective, both spindles are vertically arranged in the pivot point of the C axis. This configuration guarantees high profile accuracy and enables exact grinding and eroding processes. In addition, tool machining times can be reduced thanks to the shorter linear-axis travel distances resulting from the spindle arrangement.
VHybrid 360 can be used to produce different cutter types that are used for machining metals or composites. The machine gives tool manufacturers the flexibility to perform grinding and eroding processes on standard and special tools, regardless of whether the blanks are made of carbide, sintered PCD or brazed diamond tips. Tools with diameters of up to 50 mm, and lengths of up to 360 mm, can be processed. Depending on the configuration of the grinding wheels or rotary electrodes, larger diameters are also possible. An optionally available steady rest ensures stability for long tools, while a newly developed 5-axis control also features.
A range of automation solutions enable unmanned machining. For example, the HC4 chain magazine can hold up to 39 HSK 63A tool holders. In addition, up to eight grinding and eroding wheels, including coolant supply, can be exchanged automatically. This functionality is available for the first time credit to the Vollmer tool manager, where machine operators can select the grinding and electrode sets intuitively and easily using a drag and drop option.
The combined grinding and erosion machine is based on the established Vollmer control panel concept with a height-adjustable and pivoting touchscreen. Grinding and eroding processes are programmed, simulated and monitored via ExLevel PRO 3D software.
Axes can be selected and moved with the multifunction hand wheel. In addition, the machine has a dressing device for rotary electrodes and an integrated wheel probe for precise calibration of the grinding and eroding wheel packages.
