Why the Hauerwas machines' oscillating principle of working?
Higher cutting speeds on the external diameter of the sealing surfaces arise due to the
varying diameter ratios on the sealing surfaces to be machined, in the case of pure
turning motion. Due to the resultating different material removal, depending on the
applied working pressures, the sealing surfaces slope outwards and inwards. As a result of
the continously adjustable oscillation width, an additional sideways disc motion arises.
By this means, the differing cutting speeds are neutralized.
The greater the eccenter is set, the greater is the oscillation path. By this means, the
detrimental circumferential difference is removed. The duration of the reseating process
will be determined not only by the depth of the damage, but also by the oscillation width,
The flatness of the sealing surfaces also depends on the oscillating width.
Grinding patterns
The following advantages arise from the continously adjustable oscillation width:
