The basic philosophy of KERN Micro- und Feinwerktechnik GmbH und Co. KG
consists in obtaining the maximum machining accuracy. Hence all major machine components vital to reaching the highest precision are made by KERN according to
the same precision principles linking the development, design and manufacture
of our products.

 
Axis system (X, Y, Z)
Thecomplex design principle of the axis system is fundamental to the high overall accuracy of KERN machines. High precision roller-seated and backlash-free pre-stressed prismatic linear guides ensure constant positioning accuracies on a permanent basis. Only specially selected precision machined ball screw spindles are used for integration into the axis centre next to the incremental Heidenhain glass scales (resolution 0.0001mm). Thanks to the central alignment of the major drive and command elements, jamming of the axes is avoided. All the slideways and ball screw spindles are permanently lubricated and are therefore maintenance-free.
Differenttravels are available depending on machine types. It is recommendable to choose the biggest available travels for machine configurations including 4th/5th axes. Special customised solutions can also be offered to meet special needs.
Theaxis systems driven by DC servomotors use either the analogue (MMT and MMP) or digital technology (HSPC). Both technologies support high machine accuracy. In addition, the digital drive can increase acceleration rates considerably with a final travel speed more than doubling that of the analogue drive.
