Productivity on the highest level
The innovative powertrainhone machine concept can be applied to all known honing processes. In addition to conventional honing, innovative processes such as position honing can also be handled. The high processing and cutting speeds, and the optimised workflows significantly boost productivity even further. Whether as stand-alone machine or as integrated production lines - the modular concept provides the highest levels of flexibility in configuring modern production solutions. Standard function modules combined with customised solutions guarantee optimal results.
Optimally equipped for the future
The compact honing unit with powerful stroke and efficient direct spindle drive stands for the highest levels of flexibility. The different sizes of the models satisfy a broad spectrum of applications, with diameters ranging from 68 to 105 mm. And the integrated electromechanical feeding unit with force control (EMZ-F) ensures that process to reproduce the desired results is capable.
The fast and efficient tool change system, with its extremely short tool changing times, provides you with the best solution for a range of part types, as well as tool changing as a result of wear or process modifications. Typical areas of applications are all types of car crankcases - which means for example that inline blocks or V-blocks can be optimally processed, not to mention crank bores.

LSR
The LSR (Large Scale Reaming) honing unit of the powertrainhone series can be used as a modular machine or as an integrated solution in a transfer line. The horizontal honing unit ensures precise and effective machining of crank bores in engine blocks. Driven by a servo motor and equipped with an electro-mechanical feeding system, optimized machining results are achieved.
The machining of the crank bore improves the geometrical and positional accuracy. The used ream honing process is characterized by maintaining close tolerances and long tool life. This results in high process availability with low tooling costs. The ream honing is a contribution to the future sustainability of the combustion engine.
The LSR module can alternatively be equipped with one or two honing units and optionally supplemented by an automatic tool changer. In combination with the HSK connection, quick tool changes can be assured. Overall, this machine offers quality at the highest level.
