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.
