HM390 Application

Turbine Housing
Synergic cooperation between OEM and
metalworking companies regarding turbo-chargers
illustrates this strategy, where both parties aimed to
optimize and stabilize the technological process of
turbine housing production. The most common raw
material used was steel DIN 1.4848 – an austenitic
heat-resistant casting steel – but rationalization forces
and cost reduction pressure necessitated a switch to
cheaper alternatives: austenitic heat-resistant casting
steels DIN 1.4837 and DIN 1.4826, which are more
difficult to machine.
Leading metalworking companies were asked to
find solutions to this new challenge. ISCAR achieved
this with the integration of new insert material grade
MS32 together with cutting edge geometry and
treatment to produce tools with improved cutting
conditions and maximum insert tool life, including the
S845 SNHU 13 MS32 radially clamped insert with 8
helical cutting edges. And the market benefited from
S845 Application receiving new, dedicated tools for turbine housing
production.

On the right track
This development shows how the collaborative
manufacturer-OEM customer model has led to a
new road in tool development, and how ISCAR
applies its intellectual resources to create smart
combined tools for improved productivity and
reduced cost per unit. The automotive market
benefits from the new applications and everybody
stays on track in keeping down prices while
optimizing performance.
