BNP 300

Fully automatic 5-axis-control profile sharpening machine for band saw blades

The BNP 300 meets all requirements for processing stellite- and carbide-tipped bandsaw blades. It impresses with high precision and a long service life. Both the raker and fleam teeth, with height differences and 45° bevels, can be ground in a single pass, making the process efficient and time-saving.

Highlights

  • Profile grinding of uncoated and stellite-coated bandsaw blades
    • Using CNC axes "X" & "Y" (multiple complete rotations of the bandsaw)
    • Using CNC axes "W" & "Y" (grinding of the vertically positioned tooth)
  • Face/Back grinding of stellite- & carbide-coated bandsaw blades
    • Using CNC axes "W" & "Y" (grinding of the standing tooth)
    • Chamfering and bevel grinding of the tooth back using CNC axis "U" (for raker & fleam teeth with height differences or 45° chamfer)
  • Automatic setup of the saw
    • Positioning the saw to the workpiece grinding position (automatically)
    • Positioning the saw to the workpiece changeover position (automatically)
    • Automatic recognition of the tooth group and measurement of the tooth pitch
  • Automatic touching of the grinding wheel on the saw tooth
  • Automatic tooth form scanning "Tooth Tracing System - TTS"
