‘specials’, ISCAR is able to produce up to
2400 mm long TRI-DEEP drills.

Pistons
Much shorter and thin walled (sometimes
friction welded) steel pistons are lighter than
the conventional examples and are able to
withstand much higher loads than those made
from aluminum. T-piston geometry becomes
more complicated and requires new and
creative engineering ideas for machining difficult
to access surfaces.

grooves in one plunging operation. Bottom

combustion bowl on the upper part of a piston.
ISCAR's goal in machining steel pistons is to
reduce the number of tools needed in order to
shorten cycle times. This requires a high level
of creativity due to the fact that the machined
areas are relatively hard to access.

Although the tool has to be thin enough to
penetrate into the piston without collision, it has
to be strong enough to withstand high cutting
