TURNING INSERTS
TCMT 110204E-FM:T8415 Dormer Pramet solution:
Segment:
Automotive parts mass producer (Brazil) Trapezoidal connecting rod SAE 4140 (Alloy steel, 250 HB) Yes, water soluble oil emulsion (8%)
Component:
Material: Coolant:
Machining data:
f n
a p
v c
Application:
Hole diameter boring
709 (216)
.003 (0.07)
.039 (1.0)
Previous results:
The setup is very strict and all aspects of machining productivity vs. economy are taken into account. The competitor insert has tool life stability for 100 workpieces.
Results with T8415: After long-term testing, the Pramet insert confirms a stable tool life of 130 workpieces, which is 130% to a competing PVD insert of similar type!
SNMG 120408E-SM:T8415 Dormer Pramet solution:
Segment:
Oil & gas industry parts producer (France) Shaft for extremely corrosive environment Inconel 718 (Ni-based HRSA, 36 HRC) Yes, water soluble oil emulsion (12%)
Component:
Material: Coolant:
Machining data:
f n
a p
v c
Application:
Continuous longitudinal roughing
131 (40)
.010 (0.25)
.098 (2.5)
Previous results:
The competing insert had a tool life set to 12 minutes for process safety. The customer needs to avoid sudden breakage because the workpiece is very expensive.
Results with T8415: Long-term repeated testing has shown that we are able to achieve double tool life with the same cutting parameters without any problem or sudden failure.
CNMG 120408E-NF:T8415 Dormer Pramet solution:
Segment:
Chemical industry sub-contractor (Poland) Sleeve for chemicals pump shaft Hastelloy C-276 weld-on layer Yes, water soluble oil emulsion (8%) Continuous longitudinal semi-roughing
Component:
Material: Coolant:
Machining data:
v c
f n
a p
Application:
33 (10) .005 – .006 (0.12 – 0.15) .039 (1.0)
Previous results:
All competing inserts failed to complete a single pass through the welded layer, which is 70 mm long. The best competitor lasts up to 30 mm, then burns out from the heat.
Results with T8415: Long-term repeated testing has shown that we are able to achieve double tool life with the same cutting parameters without any problem or sudden failure.
