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 ensure the highest precision and efficiency. With the third axis, the standing tooth is precisely ground against the cutting edge, ensuring perfect cutting quality. Optionally, the tool reference point can be set automatically, either via an acoustic sensor or through the Tooth Tracing System, which scans the tooth profile. These features ensure precise positioning and improve repeatability. The ISELI BNP 200 series is flexible, user-friendly, and suitable for both standard and complex tooth profiles. It stands out with its robust construction, high reliability, and reduced downtime, leading to increased productivity and efficiency in production.

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
