Vertical turning machines, grinding machines, vertical hard turning

Hard turning, scroll-free turning, grinding

The turning and grinding centers VSC 250 DS, VSC 400 DS and VSC 400 DDS combine the advantages of vertical hard turning with those of grinding – on a single machine, in a single set-up.

These turning and grinding centers combine the advantages of vertical hard turning with those of grinding, in a single machine with a single setup. This machine contributes to process stream consolidation with all its advantages for the user: low capital outlay, low unit production costs, reduced throughput times, improved component quality and a high degree of process integrity.

Advantages

Vertical hard turning and finish-grinding in a single setup, on a single machine
All workpiece sections that can be turned with the required process reliability are hard finish-turned and only ground (after hard pre-turning) where component quality and process reliability demand
A better quality component and increased productivity levels, because the workpiece is machined in a single setup, and the hard turning process leaves a small amount of material to be ground away in the subsequent operation
The grinding wheel subjected to less wear because it does not need to remove as much stock. This reduces the frequency of dressing operations and offers advantages in cycle time
The grinding operation has to remove only a small amount of material, the grinding wheel specification can be chosen to reflect the desired finish-machining quality
Back faces are difficult to reach with grinding wheels; however, this problem is solved by employing hard turning operations
