BNF 100

Automatic side grinding machine for band saw blades controlled with 4 CNC axes in wet grinding



  • Equipped with 4 axes CNC-control
  • Powerful water cooling system with fully enclosed protection hood
  • Each action can be controlled individually by step motors which reduces idle running of the machine to a minimum
  • The user friendly touch-screen provides a clear display of the program elements
  • The advanced saw tooth can be finish ground several times in the same position
  • Auxiliary pneumatic clamping for stabilizing of thin saw teeth resulting in higher measuring accuracy
  • A special program (option) allows side-grinding of variable tooth widths, tooth pitches and tooth heights
