Fermat is a producer of high-precision, fully CNC controlled cylindrical grinders that have been designed primarily for numerically controlled grinding on a number of external, cylindrical surfaces of different diameters. Features include automatic wheel dressing and wear compensation by means of the CNC system. Grinding machines can also be equipped with an internal grinding attachment for the grinding of cylindrical and conical internal surfaces. We produce cylindrical grinders with high accuracy in the tolerance of IT4 and higher.
Grinding machines are equipped with a Siemens 840D sl or Siemens 828D sl control system, and able to grind work pieces with a swing diameter from 320 mm l 12.69″to 1000 mm l 39.37″ and a length from 1000 mm l 39.37″ to 6000 mm l 236.22″. Wheel head infeed and table travel are provided by means of servomotors and ball screws. Some of our cylindrical grinders are great for small-scale production series for work pieces with weight up to 500/ 1 000/ 3 000 / 4 000 kg l 1 100/ 2 205/ 6 600/ 8 800 lb. (optionally 5 000 kg l 11 000 lb. – heavy duty machine) according to machine design. The standard machine meets CE standards and is supplied with essential accessories and a one-year warranty.
