Birkett Cutmaster extends its range of pulse cutting bandsaws

In operation, the pulse cutting action of the PCSAW is provided by a special high output servomotor, which ensures constant blade speed control of the longitudinal force and eliminates vibration in the cutting area. In effect, for the first pulse, the servo drive wheel sends another vibration to cancel out the frictional vibration of the blade. The second pulse enhances penetration force by sending vibration dampening pulses to the blade. These mechanically induced pulses are created by a very precise set of multi-lobe cams mounted above the blade, spinning at a predetermined rpm to strike the blade at exactly the same time thus producing successive pulses that assure proper damping. These successive pulses reduce cutting resistance and tooth chipping, enabling increased blade life and improved surface finishes.
