EXTERNAL THREAD GRINDING MACHINES
RER Series
The main characteristics are the next:
- Software for all type of threading (ballscrews, worms, gauges,*.dxf profile importing.
- Built-in spindle motors
- Amply range of wheelhead designs (depending on the application and power enquiries)
- Amply range of Dressing unit designs (independent Z1/X1 configuration over the wheelhead, workhead configuration, etc..))
- Helix angle by means of automatic swivelling (+45º / -45º)
- Integration of different type of steady rests (hydraulic, manual, cnc,etc…)

Wide range of worms with modules up to 25 and profiles ZK, ZN, ZI, ZA or user loaded.
Worms
Doimak has developed a sort of applications for the gear and transmissions field: Based on RER thread grinding platform, straight and helical involute gears can be ground using latest CNC technology which includes built-in drives and linear motors.
Involute as well as cycloidal gear profiles are automatically calculated according to standard gear parameters. Dressing is made including helix angle compensation. Higher degrees of process automation thanks to different probing and component measuring solutions.
