Hard turning / grinding

The process combination hard turning / grinding is used, to great effect, to reduce cycle times. Where the complete hard finishing process (hard turning and grinding) is carried out on a single machine, throughput, transport and storage times can be drastically reduced. There are also advantages in the reduction of setup efforts and setting times.

The hard turning and grinding technology has proven its worth in the field
In the machining of chucked components (VSC DS Hard Turning and Grinding Machine) the combination of hard turning and grinding is state-of-the-art. There is, however, a considerable rationalisation potential still to be tapped, as by no means all the processes where it would be advantageous to switch to the combination process hard turning and grinding, have been changed. The future will see the increased integration into combination machines of processes such as hard milling, hard reaming and honing, in addition to hard turning and grinding. For shaft machining too, the market offers suitable machine concepts that integrate the hard turning and grinding process (VTC 315 DS Hard Turning and Grinding Machine for shaft components). The use of these systems is, however, not as common as in the machining of chucked components with hard turning and grinding technology, as there are already highly efficient systems based on conventional grinding technology, CBN technology and modern turning technology in existence. But there are signs that the advantages the combination machining hard turning and grinding brings, will also be used more frequently in the machining of shafts.

In summary, it must be noted that the combination machining process hard turning and grinding is no longer an exotic thing, but that both the technology and the machines have been well tested. The consistent use of the combination machining process hard turning and grinding and the integration of other production processes will be advantageous in tapping into further considerable rationalisation potentials.
