S242 - The Flexible machine for grinding and
turning operations The Studer S242 CNC
combination hard turning and grinding machine combines the
technologies of cylindrical grinding and hard turning in an ideal
way.
Due to the design concept of the machine
both applications can be done without compromise. In other words,
highly productive hard fine machining of shafts and chuck
components to a high quality, size holding capability and fine
surface finishes all in one clamping. Ideal for large production
series and also for small batch sizes and even single parts.
