Shrink-Fit
Tool Holders Extend Cutting Tool
Life
Cutting tool life is reduced by 10%
with every .0001" of T.I.R.
And the maximum T.I.R. with Techniks
Shrink-Fit tool holders is
.0001". Rigidity and
accuracy translates to quality
machined part finish, longer cutting
tool life and lower costs.
If you do high speed, or high torque
machining you should seriously
consider the benefits of shrink fit
technology. Your investment will pay
for itself many times over.
With shrink fit
toolholders vibration is reduced and
cutting is noticeably faster and
smoother. Manufacturing times can be
reduced while maintaining the
quality and accuracy demanded by
today's competitive markets.
How
it works
Shrink fit uses the expansion and
contraction properties of metal to
provide extremely powerful tool
holding. The bore is slightly
smaller than the tool shank, and
when heated it expands just enough
to allow the tool to be inserted.
When it cools, the contraction of
the metal holds the cutting tool
with 10,000 lbs of force.
Safe, controlled induction heat from
the shrink fit machine expands the
inside diameter of the tool holder
bore so the tool shank can be
inserted.
Automatic
air cooling contracts the bore to
hold the tool with up to 10,000 lbs
of holding power creating an
extremely rigid connection between
the spindle and the cutting tool.
