Different milling machine configurations offer varying capabilities for part
complexity, size, and production efficiency. Selecting the right machine type
is critical for manufacturing success.

**3-Axis Vertical Machining Centers (VMC):**
The most common CNC milling configuration. The spindle moves vertically (Z),
while the table moves in X and Y. Ideal for prismatic parts, pockets, and
flat surfaces. Workpiece remains stationary on the table, suitable for heavy
parts. Tool access is primarily from the top.

**3-Axis Horizontal Machining Centers (HMC):**
The spindle is horizontal, and the workpiece mounts on a table that moves in
Y and Z, with X motion via the spindle or column. Excellent for chip evacuation
(gravity-assisted), enabling deep pocket and slot machining. Tombstone fixtures
allow four-sided machining for production efficiency.

**5-Axis Machining Centers:**
Simultaneous 5-axis machines add two rotary axes (typically A/B tilting the table
or A/C with a trunnion) to the standard three linear axes. Enable machining of
complex contours, undercuts, and impellers in single setups. Improve accuracy
by eliminating multiple setups and reduce cycle time through optimized tool angles.

**Gantry Mills:**
Large-format machines with a bridge-like structure spanning the work area.
The spindle travels on the gantry beam. Ideal for aerospace structural parts,
molds, and large components that exceed standard VMC capacity. High rigidity
for heavy-duty cutting on oversized workpieces.

**Bed Mills vs. Knee Mills:**
Bed mills have a fixed vertical column and moving table, offering heavy cutting
capacity. Knee mills allow vertical adjustment of the table height but are less
rigid. CNC bed mills are more common in production environments.

**Mill-Turn Centers:**
Hybrid machines combining turning and milling capabilities. The primary spindle
rotates the workpiece for turning; live tools in the turret perform milling
operations. Some configurations include a sub-spindle for complete part transfer
and back-side machining without operator intervention.

**High-Speed Machining Centers:**
Optimized for high spindle speeds (30,000+ RPM) and rapid feeds. Designed for
light cuts at high speeds on aluminum and soft materials. Feature direct-drive
spindles, linear motors for axis motion, and enhanced chip evacuation systems.

**Swiss-Type Lathes:**
Though classified as lathes, Swiss machines combine sliding headstock technology
with milling capabilities. The bar stock feeds through a guide bushing, providing
support close to the cutting action. Ideal for long, slender precision parts
(medical devices, electronics connectors) with tight tolerances.
