GER SR CNC Profile Grinders
The machine capacities available go from 400 x 200mm up to 6000 x 1000mm.
This range is designed and built to grind all types of high precision moulds and dies, as well as carrying out all plane surface grinding operations.
The software allows the programming of all kinds of profiles direct from the drawing and also has the ability to control a CNC orientable rotary dresser to dress the profile.

Software
SRA-CNC
The machines are equipped with the latest generation Fanuc Oi-MD nano control and equipment.
The simple user-friendly touch screen control uses graphic-based software specially created by GER. The SRA-CNC machine is even easier to use than a conventional grinder and gives the performance and accuracy of a CNC machine without the complex codes. The diamond dressing is table mounted and all dressing cycles include diameter compensation.
The digital servo motor and bass screw system enable the highest levels of precision and productivity. Dressing is made easy with the aid of 9 pre-defined dressing profiles.
Main Features
- Easy component size input and adjustment by touch screen keyboard or by physical position input using “teach-in” mode.
- Dressing on demand with automatic size & speed compensation.
- Independent table and cross axis oscillation movement
- Vertical plunge and pattern grinding.
- Different working parameters for roughing/finish grinding
- Different dressing parameters for roughing/finish dressing
- Angular grinding using interpolation.
- Six programme on-board storage.
- Operator display in different languages.
- Extra in-cycle dressing can be performed at any time during the automatic grinding cycle.
