A fixed wheelhead enables swivel positions of 0, 15 and 30 degrees, offering additional flexibility for straight and angular
plunge grinding in one machine.
A cutting mode for cylindrical
plunge grinding shall be determined by:
In face
plunge grinding, the rotating compound grinding, wheel, which covers the entire wafer surface, is fed continuously in axial direction (Figure 2).
You just waste a lot of time and end up going back to where you were: grinding the shaft ODs on two machines and then
plunge grinding the tapers on a second machine."
The machine's design features, in combination with the exclusive rotary
plunge grinding process, provide parallelism, flatness, size control, and squareness.
Therefore, Rosler uses rotary and trough-style vibratory bowls,
plunge grinding and drag finishing units, or Rotomatic continuous flow systems for processing of such delicate work pieces.
Meanwhile, Karstens' shaft-grinding expertise was combined into a horizontal-spindle machine, with a very fast, linear-motor-powered workpiece transfer, in which the workholding system, common to both machining functions, progresses the job through hard turning and then
plunge grinding. That machine made its debut at EMO 99 in Paris.
As long as the production runs are large enough to justify a dedicated grinding operation, standard
plunge grinding solutions handle this requirement adequately.
The machine offers straight
plunge grinding and 15[degrees]
plunge grinding.
Additionally, centerless grinding with and without centers is possible, as is peel grinding and
plunge grinding on a common platform.
For cylindrical
plunge grinding, a grinding width of 127mm is available while for angular in-feed grinding the width is 90mm.
