Series BG/NT
Flat bevel grinding machine
BG/NT: Surface and bevel grinding
The CNC controlled grinding machines of the series BG/NT grind surfaces on knives, scissors, hand tools and related workpieces. The BG/NT is the update of the original BG series. Depending on the size of the workpiece to be machined, the machines are equipped with grinding wheels of different diameters.
New features of the NT version
- linear motor in the main feed axes (X)
- helical direct gearbox in the A-axis and in the /RV machines also in the B-axis, thus higher rigidity in both axes
- new machine body with enlarged water outlets and optimized, sloped water channels
- new headstock with reinforced bearings and guide system for drive motor with pulley, elimination of multi-spline pulley
- servo drive and ball screw for the headstock with integration as additional axis in the CNC control system
- new measuring control type BEM-Digital/Diamond and BEM AE (ultrasonic)/Diamond for stone compensation
- new PC-based Windows control Andron or Siemens
Technical specifications
- grinding length: 150–640 mm (depending on model)
- mounting flange for grinding wheels from 80–710 mm ∅ (depending on model)
- spindle drive 6.5–45 kW (depending on model)
