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.
