WhizCut of Sweden AB
has developed a new and unique back-turning insert for its insert
tooling system for automatic lathes.
The insert has two
cutting edges, a 12° positive cutting rake and a chip former
that will steer the chip away from the work piece. The special
design of the cutting edge allows the insert to have contact with
the work piece only along the straight cutting edge and a short
part of the wiper edge. The radial pressure is hereby
considerably lower than with conventional back turning tools.
The combination of
positive cutting edge, low cutting force, low radial pressure and
short length of contact has resulted in better roundness of the
turned diameter, easier to keep small tolerances, better surface
finish, fewer adjustments during the tool-life of the cutting
edge and considerably longer tool-life.
