S121 RADIUS

The Compact for small precision components.

Basic Data

The S121 is a radius internal cylindrical grinding machine. It is the ideal machine for internal, face and external grinding of chuck components. The maximum swing diameter is 300mm (11.8″) and the maximum workpiece weight is 100kg (220lbs).

The radius internal cylindrical grinding machine is especially suitable for grinding complex workpieces from very hard materials such as tungsten carbide, ceramics and sapphire as well as for general grinding tasks. It has a host of sophisticated technical features such as the revolutionary StuderGuide® guideway system, high-precision axis drives with linear motors, a fully automatic B-axis with direct drive, etc.

Hardware / Software
