As the smallest all-purpose SMS thread grinding machine, the type RAG is used for precision grinding all types of male threads of small dimensions. These can include small threading tools such as thread-cutting taps, forming taps and thread gauges. The stable basic structure of the machine enables high productivity and precision (machine basis: Reishauer thread grinding machine type RAG).

The machine is equipped with the latest drive and control technology (digital servo drives: Bosch-Rexroth, precision length measurement systems: Heidenhain). Thanks to the workpiece-specific user interface by SMS (HMI), the CNC control system (Bosch Rexroth MTX) can easily be programmed by the operator in the dialogue system and ensures short setup times. Equipped with modern CNC dressing technology, the machine is highly flexible and can grind all types of threads – also with special profiles.

For series production, the machine can be equipped with an optional automatic loading system – consisting of an integrated robot (Fanuc) and a pallet station or magazine installation for Reishauer cassettes. The machine is also available as a 3-axis version with a table-mounted dressing unit.

For dressing/profiling single tooth as well as multi-tooth grinding wheel profiles, a variety of dressing units (for diamond form rolls as well as diamond profile rolls) are available.
