Further development

The vision for the further development of the BAYER press-in system was to standardise the electrical hardware by following the SIEMENS standard and to integrate the possibilities offered by the control technology (rapid switch-off, plausibility check by the current) and IT (database, visualisation, evaluation by superimposing curves).

On the mechanical/kinematic level, the feed speed of the press-in unit was increased by approx. 60%, as well as the maximum pressing-in force (here depending on the load case). The distance between the centerlines of two press-in units is 78 mm matching the gauge for boreholes of cylinder heads by pressing-in valve seat rings and valve guides.

KWP 40

KWP 40 (force/distance processor) offers access protection for various different user groups, which can optionally be assigned via EKS® key. Up to 16 channel pairs (force/stroke) can be visualised.

Technical data:

  • Visual curve comparison by superimposing the curves to set the evaluation windows

NB 220

In addition to an improved infeed speed and an increase in the maximum pressing-in force (depending on the load case), the press-in unit NB 220 is able to provide a tensile force. The installation space was further reduced and the maximum possible stroke was increased.
