As with all machines from BUDERUS Schleiftechnik, the large series also relies on complete machining of the workpieces in a single clamping operation. This eliminates non-productive times for loading and unloading several machines. This is particularly advantageous for large components, where the non-productive times sometimes approach the main times.

However, the biggest advantage of complete machining is the elimination of the reclamping process itself. Since the exact same center is never achieved when the component is reclamped, significantly lower tolerances can be achieved with complete machining, especially when the machined surfaces run in relation to each other.

Thanks to the DVS modular principle, the workspaces of the BV hard machining center can be freely configured to perform as many machining operations as possible in one clamping. Equipped with several cross slides, not only complete but also simultaneous machining is possible.

The cross slides can be moved independently of each other in different directions. This enables the tools to carry out different machining tasks. For example, internal and external cylindrical grinding operations can be carried out simultaneously or combined simultaneously with turning operations. In this way, the machining time can be significantly reduced without compromising the achievable workpiece accuracy.

One to four cross slides run on the hard machining center in backlash-free, high-precision roller guides. These guides consist of a guide rail and the movable slides, which are equipped with roller bearings. This allows high rapid traverse speeds and very small feed movements without a stick slip effect, while maintaining maximum temperature stability without energy-intensive oil cooling. The slides are guided evenly along the entire stroke length in both axes, which means that inherently rigid cutting conditions are achieved across the entire working range.

Processing large components places particular demands on the machine system. The high workpiece weights often make it difficult to handle the components. For this reason, the BV series has a fixed vertical spindle on which the workpieces can be placed relatively easily using lifting equipment.

In addition to gripper systems which, combined with various workpiece conveyors, enable automatic loading of the machine, a two-spindle solution is also available. This allows processing to take place on one side of the machine while the other side is being set up. This virtually eliminates non-productive time for changing workpieces.

For medium-sized and large machines, the spindles are supported axially and radially separately in precision roller bearings. This ensures high concentricity and axial run-out accuracy even with high weights and asymmetrical load distribution.

Overall, the BV is a machine for large workpieces that combines both flexibility and productivity by consistently utilizing the DVS modular principle. This means that the machine can be specially adapted to your application or your range of components. With the large number of possible variants, your machine is sure to be included.
