The machines have been designed for high-precision grinding of flat surfaces of various articles, and when the grinding wheel periphery profiling and installation of attachments are used – for machining of profile surfaces, slots, shoulders, and also grinding with wheel face.

Design advantages:

  • The rational design of the base, compound slide, column, table and wheelhead ensures the machine high rigidity and vibration-free operation providing stable precision and purity of machining.
  • The use of backlash-free rolling ball-screw pairs in the feed units ensures smooth, high precision, backlash-free positioning.
  • All working travels on machines are automated.
  • It is possible to equip machines with the electric components of leading world producers such as: "Siemens", "Balluff".
  • Basic parts made from cast iron.
