INTRODUCTION
Our bandsaw machines are designed to be installed with high quality using high speed saw blades for
maximizing productivity. To be able to use this kind of high performance bandsaw blade, the machine
has to be of rugged design, has high quality saw blade guides, has sufficient motor horse power for
high saw band speeds, and has to be able to apply necessary tension to the saw bands. Your machine
has all these features to provide a better service for you.
The saw blade is guided through the cutting area by roller guides to keep it straight as it comes off
the driving wheels. The precision carbide inserted guides then hold the blade securely and accurately
throughout the sawing process. The tension of the saw blade is adjusted through the tensioning
device on the strong saw bow. The cutting feed and down feed pressure of the blade is regulated
automatically by hydraulic regulation.
