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

Cutting Off, Grooving & Forming

Gang Cutting






Benefit: More parts per hour
Faster feed rates (1-1/2 to 3 times that of single point tooling) reduce cutoff times and increase the number of pieces cut per hour. In addition, RSC greatly increases the number of applications that can be "gang" cut. The negligible saw and part deflection minimizes the problems usually encountered when attempting single point gang cutoff; the saws themselves act as guides to eject the cut part.

Due to light cutting pressures, not only can length dimensions, flatness, squareness, etc. be held to a very close tolerance , but they can be repeated within tenths, thus making SPC easy.

Saws, without the need to change feeds or speeds, cut effectively over a wider range of surface feeds. Deep cuts can be accomplished with one tool and without sacrificing cycle time. As a result, one less tool needs to be maintained and an extra tool station is gained.

The Kerf Cutters are designed with quick and easy tool changes in mind. Changing a saw takes only a few minutes. Adjustments are rarely necessary because height settings repeat every time. Location settings may need occasional changes, but only to maintain the tightest length tolerances.

Saws easily cut 5 to 10 times as many pieces per grind as do single point tools of comparable material. Because of the light chip load, the interrupted nature of the saw cut (each saw tooth cuts for only a brief moment at a time), and the side clearance on saws, a rotary saw cut builds up very little heat. The heat stays in the chip which is immediately carried away from workpiece and saw by a strong coolant flow. Therefore, tool life is greatly improved because cutting off is far less demanding on a saw than it is on a single point tool.

Reduced tool maintenance, quicker tool changes, easier chip management, and fewer stock ups due to more parts per bar, all contribute to higher production levels.
