A milling cutting tool is similar to the
turning cutting tool, but many tools called
“teeth” integrate it.
• The tool is spinning (Mc).
• One or more linear movements
(Mp & Ma) may have the tool or the
part.

• Several technologies are integrated into one machine:
turning, milling, drilling,…
• It has evolved from turning machines.
• The heart of the machine is the tool spindle (B
spindle), which even can be tilted. It provides milling,
drilling and tapping capability along with turning,
facing, grooving and threading.
• This spindle is serviced by an automatic tool changer
that resides outside the cutting zone.
• It may have a double spindle and one/two tool turrets.
• Application: very complex parts.

• It has evolved from 5 axis machining centers:
a) High rpm capability of the C axis (turning table).
b) Adopting the spindle for stationary operations.

 It requires a previous slot milling operation of width
bigger than the T-shape tool shank.
 The use of air flow is highly recommended in order
to evacuate the chip continuously.
T-shape Slot Milling
