BNP 200 [G2]

Fully automatic profile grinding machine for
band saw blades with 4-axis CNC control

The ISELI BNP 200 series combines advanced technology with innovative design to deliver maximum precision and efficiency in band saw blade grinding. The third CNC axis grinds the stationary tooth precisely against the cutting edge, guaranteeing perfect cutting quality in every pass. For even greater accuracy, the tool zero point can be set automatically – either via an acoustic emission sensor or the Tooth Tracing System, which scans and stores the tooth profile for fully repeatable results. Flexible, intuitive, and built to last, the BNP 200 series handles both standard and complex tooth profiles with ease. Its robust Swiss construction, high reliability, and minimal downtime make it a smart long-term investment for any professional sharpening room.

Highlights

  • Profile grinding of uncoated and Stellite-coated band saws
    • Using CNC axes "X" & "Y" for multiple complete passes of the band saw
    • Using CNC axes "W" & "Y" for grinding the standing positioned saw tooth
  • Face/Back grinding of Stellite and carbide-tipped band saws
    • Using CNC axes "W" & "Y" for grinding the standing positioned saw tooth
    • Optional adjustment of grinding parameters for different tooth geometries
  • Automatic setup of the saw
    • Automatic positioning of the saw to the workpiece grinding position
    • Automatic positioning of the saw to the workpiece changeover position
    • Automatic detection of the tooth group and measurement of tooth pitch for maximum precision
    • Enables fast setup and reduced setup times
  • CNC-controlled cutting angle adjustment ("S" axis)
  • Automatic probing of the grinding wheel on the saw tooth
    • Ensures precise tool zero-point determination for maximum accuracy
  • Automatic tooth profile scanning with "Tooth Tracing System - TTS"
    • Precise capture and storage of tooth profiles for repeatable grinding results
