While the majority of the workpiece is machined with PCD,
carbide cutting edges are used for the steel area.
World first for external machining
On the outside, the part features a helical circumferential
groove. Because the coolant later flows through this groove
after it’s been inserted into the outer housing, the stator carrier
is also known as the “cooling jacket”.
MAPAL is presenting new external machining tools at the EMO
in Milan. They are among the more unusual tools. After pre-
machining, a bell-shaped tool takes over the complete finishing
of the outside. The specifically designed lightweight tool is
equipped with indexable inserts and guide pads and was
provided with bars in the right places to save as much weight as
possible and to get rid of chips through large openings. The fine
machining tool promises high roundness and accuracy.
Complete machining on machining centre
Internal machining is possible very quickly and accurately with
the boring tools. In addition, the outside can also be machined
in the same clamping setup without moving. The machining
centre solution caters to customers who are embracing the
transformation to e-mobility with existing machinery geared to
machining large cubic aluminium housings.
Those who start their production on a greenfield site can, of
course, choose which machining strategy is best for them.
MAPAL has developed an alternative machining solution in a
joint project with a machine manufacturer. In this case, the
process was rotated 90 degrees for use on vertical lathes.
