BNT 100

Fully automatic deep-grinding production center for bandsaw blades

ISELI BNT 100, Vollautomatisches Produktionszentrum


  • Designed for the fully automatic new toothing of bandsaw blades with the deep-grinding stack process
  • Extra heavy welded construction in a space-saving compact design
  • The space-saving machine design allows for high ergonomics and excellent usability
  • Easy access for maintenance work to the electrical cabinet, coolant pump, pneumatics and extinguishing systems
  • Optimal, fast and safe programming and setup of saw parameters
  • Extra heavy welded construction in a space-saving compact design
  • The entire work process is programmed via the 3-axis CNC control system
  • All standard tooth shapes are supported thanks to a profiled special grinding wheel with diamond roller dressing system
  • The material feed, stack clamping and grinding wheel dressing are carried out automatically via a touch panel with self-explanatory operator guidance
  • The separation of the electrical area from the work area as well as few moving parts increase the maintenance friendliness and the longevity of the machine
  • Remote maintenance and remote diagnosis are possible without any problems via LAN / WLAN connection.
  • For easy equipping and retooling, the full guard of the area can be raised
