Milling and Grinding Center in One 

High-precision milling and coordinate grinding on the same machine 

Versatile and economical – one machine for two processes.

The FEHLMANN VERSA family is impressive — with its solid construction and remarkable mechanical accuracy. High temperature stability with extremely low thermal growth is another one of the amazing features of these versatile machining centers in portal design — making them the ideal
machines to use for coordinate grinding.    The decision whether to use hard milling or coordinate grinding requires the evaluation of costs, machining time and precision. FEHLMANN solves this problem with the VERSA 645 linear and the VERSA 945 with coordinate grinding function. 
Both processes are perfectly combined on one machine. You can decide case-by-case and with great flexibility how to achieve the desired surfaces most economically.  

Advantages of combining hard milling and grinding:
 

• Versatile and economical – one machine for two processes
• Time-savings with one-time clamping of workpiece for milling and grinding. No more re-clamping necessary
• Shorter machining times thanks to two processes on same machine
• Multi-use of precision: make a one-time investment in high precision and benefit twice thanks
  to the combination of milling and grinding
• Increased efficiency due to high process reliability
• Parts can be precisely pre-milled before grinding, ensuring a perfectly pre-finished part.
  Elimination of varying offsets caused, for example, by warpage during hardening
• Consistent excellent surface quality and contour accuracy: due to choice of most
  suitable machining strategy and automatic dressing of grinding tool
• Simple programming: grinding functions such as pendulum stroke and dressing can be
  easily integrated into the program after milling
