Machining of microtools made of hard and ultra-hard materials with maximum surface finish
The VHybrid 260 is the only hybrid machine on the market that meets the high requirements for the production of PCD micro tools. Thanks to the innovative Vpulse EDM generator, the smallest microtools with diameters of 0.45 millimetres and below can be produced with the highest precision, performance and surface finish.
Progress in areas such as medical implants and wearables means that electronic components are becoming increasingly fine and delicate. For this reason, smaller and smaller tools are being used in manufacturing processes in the medical technology and electronics industries. PCD microtools with diameters of 0.45 millimetres and below are in particular demand for the production of printed circuit boards.
Microtools are also used in micromechanics and the watch and jewellery industry. With the VHybrid 260, a surface finish of up to 0.05 μm/Ra and a cutting edge radius of up to 1.5 μm is achieved.
One of the reasons why the VHybrid 260 is able to sharpen so precisely is the VOLLMER machine‘s innovative and robust kinematics. Tool manufacturers can use the VHybrid 260 to grind or erode both carbide and PCD tools up to 100 percent in one set-up. The sharpening machine is based on multi-layer machining, which is implemented through two vertically configured spindles. The lower spindle can be used both for grinding and for eroding.
Very rigid, compact construction with optimal accessibility and overview for the operator.
Grinding spindle and eroding spindle (bottom) are positioned vertically in the pivot point of the C axis. The result: Reduced machining times thanks to shorter linear-axis travel distances.
MODERN CONTROL-PANEL CONCEPT
Height-adjustable, with touchscreen, 19" diagonal screen size and optimum view into the machining chambers.
ExLevel Pro and VStandard for a comprehensive range of tools for drills and milling cutters. For greater flexibility and variety.
Even greater flexibility for your production processes. Space for eight HSK 50 grinding and eroding wheel sets.
Such as with the HC 4 or the HC 4 plus for increased capacity and flexibility.
To ensure optimum concentricity of 2 μm when machining microtools, the VHybrid 260 is equipped with an insulated shank steady rest, which also allows it to be used for eroding. Furthermore, due to the „Laser Check“ integrated measuring system, required tolerances of ± 2 μm can be achieved during fully automatic machining in a closed-loop process and enables complete machining in one set-up.
