Electromechanical press-fit from Kistler
15 May 2008
Electromechanical joining systems are increasingly supplanting the familiar hydraulic presses and joining modules in electromechanical press-fitting applications. In addition to better environmental compatibility, a more favourable energy balance, compact design, minimal installation effort and very low-maintenance operation, it is primarily production aspects (flexibility, exact positioning, extremely high reproducibility and accurately defined press-fitting forces) that make an electric system a more obvious choice for the system designer.
With the new generation of its electromechanical NCFH Press-Fit Systems, Kistler offers a particularly compact and precise system solution for a wide variety of force displacement monitored press-fitting and joining tasks. The new integral piezoelectric force measurement technology allows just two sizes of spindle to cover the wide measuring range between 1kN and 60kN – a small one for up to 10kN and a large one for up to 60kN.
Provided the machine design remains unchanged, this ensures spindle interchangeability under different conditions. Their shortness and compactness also make the electromechanical NCFH Press-Fit Systems suitable for under-bench mounting. With an overall height of approx.475 or 795mm they offer a stroke of 200 or 400 mm, which allows them to reach extended end points, such as bearings in transmission half shells.
