Figure 2
The ring saw produces large, uniform chips that are easy to collect. This eliminates the time
normally lost for chip removal and reduces the potential for metal fines to get into the
slides, bearings, and other machine components.
In some cutting technologies, the blade
teeth experience high impact loads and
have a brief “in-metal” time. On the other
hand, the ring saw’s cutting inserts are
tapered and brought into contact with the
workpiece gently so there is no impact
(see Figure 1). The table’s two-axis
motion maximizes the in-metal time and
optimizes the chip load.
A LONG-TERM VIEW
Many times the decision-makers look
at the upfront cost of the machine when
they really should look at the cost of
each cut. In other words, it’s illuminating
to consider the machine’s long-term
operating cost, not just the initial capital
investment. Oftentimes saving a few
dollars upfront results in decades of high
operational cost.
