Customer requests – application:

  • Inner diameter and face turning of rotating parts
  • Material: cast iron EN-GJL-250


Machine tool:

  • vertical lathe (carousel) 12 CNC B (man. TOS Hulín)
  • machine table: diameter 1250 mm
  • working diameter: 1 300 mm
  • working height: 700 mm
  • workpiece weight: 12 000 kg


Cutting conditions:

  • Clamping side of parts – pre-machined
  • Feed: min. 0,2 mm/rev.
  • Rotations: 70/min
  • Cutting depth: 5 mm



Due to the nature of the material (cast iron parts), we chose reinforced magnetic system (added NdFeB magnets). Top plate was executed with T-slots in order to allow additional mechanical fixing of parts. El connection was realized by means of quick coupling (bayonet) connector placed on the magnet´s body and secured by anti-leakage cap.
