solution to extend the life of the new VMC machines.
According to Schuster, “Dependability of the ma-
chining center is very important, and using the JMPP
High Torque retention knobs should reduce the
failures associated with traditional retention knobs. I
specifically like the low tightening torque required to
seat the retention knob into the tool holder. I imme-
diately implemented about 30 of these and plan to
use them exclusively on all of my TRAK machines/V-
Flange systems moving forward.”
HIGH TORQUE / CARBIDE TOOL TEST:
Increasingly, the automotive industry is using more
carbide tools primarily because they can cut both
aluminum and hard materials such as titanium, car-
bon, and exotic alloys at high speeds. Carbide tool-
ing is expensive and also fragile, so it’s imperative to
watch for microfractures which yield poor surface
finishes. If a microfracture occurs, the whole tip may
disappear and the inserts can be rendered useless.
Recently, Sandvik, Inc. (Fair Lawn, NJ), a high-tech
and global engineering Group with about 42,000
employees, lent out one of their engineering rep-
resentatives to test the best retention knobs for
Caterpillar® with a $1,200 solid
carbide tool. The specification
included: a toolholder, reten-
tion knob, tightening spec,
proper placement, and then
lock it down. The test’s goal was
to get the custom carbide tool
to run without shattering.
A variety of standard retention
knobs did not work. When
tested with JMPP’s High Torque
knobs tightened to their pro-
vided torque specifications,
it worked every time with no
tool shatter. After witnessing
the dramatic testing results,
the Sandvik rep stated, “The
JMPP knobs may be the biggest
savings to the industry for the
next ten years. They are better,
faster, provide unbelievable
feeds, and can reduce set up
times by 40-60%.”

V-Flange tooling by design should be the most
efficient, precise and cost effective tooling system
available.
The fact is, a carbide tip cannot vibrate when it
makes contact, or it shatters. Essentially, carbide
must smoothly enter into the pocket and maintain
its position in the pocket or it breaks. Carbide can
last a long time with the right chip load and RPM.
It could last weeks, but let it vibrate and it could be
minutes. JMPP’s High Torque knobs have been prov-
en to extend carbide tooling life.
HIGH TORQUE AUTO / CONCLUSION:
Ultimately, by making a simple change…moving to
the High Torque retention knobs, CNC manufactur-
ers across the board can eliminate the vast majority
of issues, improve their milling operations, and get
the best results while saving money. Moreover,
this solution creates a real opportunity for U.S. tool
shops to grow along with their automotive OEM and
Tier One customers in creating progressive tooling
cost containment solutions.
This High Torque solution is so potent, that JMPP
guarantees the results their
customers have been realizing
on any V-flange toolholder that
is made to the AT3 or better
taper tolerances. They offer to
provide High Torque retention
knobs at no charge for testing
purposes to any manufacturer
willing to provide tracked tool
life prior to and post-installation
of the knobs. JMPP maintains
that their High Torque retention
knobs are the only tool that can
deliver increased productivity
and performance on virtually
every V-flange tool used in CNC
manufacturing.
