Background information

Why it works

More parts per hour:

  • Faster feed rates
  • Gang cutoff
  • Easy SPC
  • No stringy chips
  • Freed up tool station
  • Faster tool changes
  • More pieces/tool grind
  • Fewer stock ups
More parts per bar:
  • Kerf reduced by up to 75%
  • Less facing stock
  • Fewer pieces scrapped
Less/no secondary work:
  • Cutoff is flat, square, and smooth
  • Lengths repeat consistently
  • Small, flimsy burr
  • No nib
Increased capabilities:
  • Exotic materials
  • Irregular Shapes
  • Thin-walled tubing

Gang Cutting






Benefit: Less/no secondary work
The low cutting pressure allows the saw to cut completely through the piece for a clean, smooth cut. Thus, RSC virtually eliminates the cutoff nib and significantly reduces burr resulting in a better quality part. Furthermore, with RSC, tool and workpiece deflection are negligible; surface flatness and squareness are typically within .002" and often even within .001". This is still attainable while feed rates are 150% to 300% of single point cutoff rates, and without the assistance of workpiece supports. Length dimensions not only can be held to a very close tolerance, but can be repeated within tenths.

On the other hand, the high cutting pressure of a single point cutoff tool causes the part to break off leaving a large nib and excessive burr. Likewise, the same pressure limits the length of stockout over which multiple cutoffs can be taken effectively.
