10.7 Use of rolling process
Although we have achieved "using turning instead of
grinding" for large shafts through turning, in order to more
reliably control the roughness, we have added a rolling process
to further enhance the roughness.

The MAZAK E670H-4000U center frame has a clamping
range of D135-D460, while the MAZAK E670H-6000U center
frame has a clamping range of D350-D700. Parts processing Figure 19 Form of rolling tool

There are many types of rolling tools, as shown in Figure
