Using proprietary technology, Hollymatic’s Defender 4000 Band Saw effectively stops the saw blade with no damage to the saw at a rate 10x faster than the blink of an eye! That’s taking safety further than it has ever been! Hollymatic uses a new high speed camera processing algorithm at 500 frames per second and a total processing and output time of under 4 milliseconds. Blade stopping speeds are under 40 milliseconds. That’s .040 seconds with a proprietary low inertia high horsepower servo motor. Hollymatic’s Defender Band Saw also features a highly specialized drive unit and a proprietary, zero backlash, wash-down duty gearbox.
