Services

6. Tooling Reclamation
• With nearly 40 years machining experience, NTR have assembled
and trained the best group of manual milling and fitting engineers
within the sector. Over the many years we have been repairing
pocketed tools our staff have developed some of the most advanced
techniques within the industry which is why so many customers
entrust us to repair their tools.
• Technological advances have also assisted and we now use a
combination of manual and 5-Axis CNC technologies to ensure your
tools are repaired to perform and look as new.
• CNC machining of pocketed tooling now means that cutting tools
once considered scrap or beyond repair, can now be renewed.
• Most U-drills, CAPTO, KM/BT block tooling and Ball Nose cutters
are repaired on CNC.
• In all cases coolant holes are fully restored.

12. Stage 1: Tool with
Outer Diameter and
pocket areas badly
damaged.
Stage 2: The drill is
strip-down and pockets
cut out. This enables us
to assess the structural
integrity of the tool and
also provides assurance
of proper deposition of
the root weld.
Stage 3: The drills is
welded using our
advanced precision
welding technology and
metallurgy study that
guarantees compatibility
between base metal and
filler rod.
Stage 4:
The pockets are
milled and finished
to the required
quality standard
using our integrated
CNC technology to
guarantee the
tolerance.
Stage 5: At final
inspection the
screw holes,
tolerance and
finish quality are
verified. The tool
is then labelled,
oiled and packed
for delivery.
Example: Reclamation process for a Short Hole Drill
Example 1

13. Stage 1: A Long Edge Milling
Cutter and Face Mill with the
top pocket severally
damaged.
Stage 2: The tool is
stripped-down ensuring
any “pick-up” is
removed. The damaged
pocket has been welded
using a filler rod that
closely matches the
parent metal. This
guarantees the tool
longevity during use.
Stage 3: Pockets are
then precision milled, the
outer diameter re-
grounded using our
flexible machining
capabilities and
calibrated measuring
equipment.
Stage 4: Tool finished, screw
holes are precision drilled, tapped
and countersunk. The tool is
deburred before it is polished.
Stage 5: Tool is bead blasted and
inspected - screw holes, tolerances
and finished quality are all verified.
An inspection certificate is
prepared before it is labelled (our
seal of quality), oiled, packed and
shipped.
Example 2: Face, Shell, Shoulder and Long Edge Cutter reclamation process
Example 2

14. Stage 1: Capto tool holder with outer
body and pocket area badly
damaged.
Stage 2 (Not in Picture): The pocket is
stripped down, contaminates and
damaged areas are ground away
guaranteeing the micro-structural integrity
of the weld substrate.
Stage 3: It is then welded using our
advanced precision welding technology
ensuring compatibility between base
metal and filler rod.
Stage 4: The pocket is Milled,
Finished and glass bead blasted.
Stage 5: At Final Inspection screw
holes are checked, the tolerance
measured and finished quality
verified. The tool is then labelled,
oiled and packed ready for delivery.

• Refurbished tool ended with a positive

– Bending?
– Pocket Deformation?
– Not Significant?
• The new tool required more inserts
– Abnormalities on the Pocket?
– Weaker Inserts?
– Freak of Nature?

58. Observations & Conclusions
• Both tools required the same number of Offsets
and of similar magnitudes
• Equal amount of time spent altering machine
• NTR’s Reclaimed Tools Performed like New in a

59. Customer
Case Study

60. Toyota
Problem facing Toyota:
– Poorly managed tooling reclamation service resulting in repaired tooling not
being compliant to drawing and rusting.
Solution:
– NTR worked with Toyota to agree a formalised process for tooling repair in
order to address the above issue.
Process:
– All tooling is reworked to drawing
– Spares identified and an order placed in advance before work commences
– Tools are repaired to specified tolerance and issued with certificate
– Tools are then oiled and bagged to avoid possible rusting
– Before being returned by NTR to the store department
This is a Premium Service offer to Toyota.
