Milling CNC Parts Aluminum Turning Parts
CNC machining is a subtractive manufacturing process, meaning it achieves its final product by
removing material.
It involves tasks like drilling holes, creating slots and pathways, and shaping metal stock into
different forms with varying dimensions and designs.
Unlike additive manufacturing, which builds up materials layer by layer, CNC machining subtracts
material to create shapes. It also differs from injection molding, where material is injected into a
mold to form a specific shape.
CNC machining is highly versatile and compatible with a wide range of materials, including metals,
plastics, wood, glass, foam, and composites.
This versatility has made CNC machining a popular choice in various industries, offering efficient
and precise fabrication for designers and engineers.
Product Details
CNC machines excel at cutting a wide range of materials, including aluminum, bronze, copper,
ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering materials.
This versatility makes them perfect for crafting prototypes during product development.
With CNC milling, you can easily fine-tune and make precise adjustments until you achieve the
desired final product, offering accuracy and efficiency throughout the manufacturing process.

Specialist Industries
CNC machining services find applications in various industries, catering to specific needs and
demands:
1. Transportation: CNC turning plays a vital role in crafting components for the aerospace,
automotive, mass transit, rail, locomotive, military, and trucking sectors.
These industries rely on CNC machines to produce essential parts like headnuts, gear blanks,
bearing blocks, levers, axles, and rotors for transportation equipment.
2. Construction: The construction industry requires robust components capable of withstanding
heavy loads.
CNC machining is frequently employed to manufacture bolts and screws from materials like
stainless steel and aluminum, essential for assembly and fastening tasks.
3. Automotive: CNC turning services are indispensable in the automotive sector, producing critical
auto parts including cylinder heads, connecting rods, camshafts, transmission components like
shafts and rings, suspension parts such as sway bars, control arms, tie rod ends, as well as various
items like bushings and bolts.
4. Aviation: The aviation industry heavily relies on CNC turned parts for customization and the
production of probes, joint connectors, fasteners, and engine and aircraft components.
Many aviation components utilize titanium due to its ability to withstand extreme temperature
variations, making it a preferred material for critical applications.

Geometry-Based Cost Reduction Strategies
To reduce manufacturing costs related to part geometry, consider the following tips:
1. Simplify or Downsize Shapes:
Make shapes simpler or smaller when possible.
2. Minimize Fine Details:
Avoid intricate details in shapes to reduce complexity and machining time.
3. Corner Optimization:
Avoid sharp inside and outside corners, which may require specialized tooling.
Increase the radius of inside and outside corners for smoother machining.
4. Material Efficiency:
Design shapes that minimize material wastage.
For instance, consider breaking down a large U-shaped part into three separate sections to avoid
wasting material in the center.
5. Hole Standardization:
For 3D parts, minimize the number of different hole diameters to simplify machining.
6. Complex Shapes:
Avoid shapes with long protrusions, thin sections, or extensive material removal requirements.
7. Work-Holding Considerations:
Design parts that do not require complex work-holding setups.
Rectangular parts are the most practical, followed by round parts (requiring milling), while shapes
with intricate outer profiles are more time-consuming to set up for machining.
8. Slot and Channel Widths:
Make narrow slots and channels wider, as narrow areas necessitate smaller cutting tools, which work
more slowly.
9. Edge Treatment:
Avoid adding explicit chamfers or rounded edges in the CAD design, as these can often be addressed
using more cost-effective methods during the machining process.
10. Integrate Protrusions:
Inside deep pockets, connect protrusions close to walls (e.g., mounting posts) to the wall to eliminate
separate "islands" within the pocket.
Implementing these geometry-based cost reduction strategies can help optimize part designs for more
efficient and cost-effective CNC machining processes.
