MoreThe 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.
More2012-11-15 The grinding/machining procedure is to rotate the grinding wheel at maximum rpm, counter-rotate the material to be machined at high rpm, and move the grinding wheel along the same path that the turning tool would have taken. This process is similar to turn-milling except that a grinding wheel is used instead of a milling cutter.
MoreHowever, hard turning has become widespread since its introduction and has replaced many grinding processes worldwide. Nevertheless, both processes are fundamentally sound but differ and which method is best suited depends on the workpiece to be machined and the number of parts in a production run.

MoreIn 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.
MoreThe process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding. However, when it is applied for finishing where form and dimension are critical, grinding is superior. Grinding produces higher dimensional accuracy of roundness and cylindricity. In addition, polished surface ...
