S33 - The reasonably priced for individual requirements
The Studer S33 CNC is a versatile universal cylindrical grinding machine designed for the grinding of medium sized workpieces in individual as well as small and large-batch production. It can be easily adapted to other grinding tasks by means of various accessory kits such an in-process gauging, balancing system, contact detection (Sensitron) and length positioning.
It can be automated using the Studer smartLoad to give and is especially suited for use in the tooling and precision mechanics sectors. The proven pictogramming allows even less experienced users to quickly optimise the potential of this machine.
