Aerospace Parts CNC Machining Stainless Steel Parts CNC Turning Parts Factory
CNC (Computer Numerical Control) machining is an automated process that involves using a
machine to remove material from raw stock based on computer-generated instructions.
It is applicable to a wide range of materials, from expanded polyurethane foam to nickel
superalloys. Common applications for CNC machining include manufacturing, crafting
ornamental furniture, and producing turbine blades.
The cost of CNC machining is influenced by factors such as precision requirements,
surface finish, quantity, material selection, and the complexity of the part being produced.
Product Details
The turning process predominantly employs metals as its primary materials.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
Nonetheless, this versatile process can also be applied to machine plastic components and work
with an array of other materials, including ceramics, composites, thermoplastics, and thermosets.
| The Most Popular Materials | |
| Name | Characteristics |
| Aluminum 6061 | Good strength-to-weight ratio, excellent machinability, low hardness |
| Stainless Steel 304 | Good strength-to-weight ratio, excellent machinability, low hardness |
| Brass C360 | Excellent mechanical properties, resistant to corrosion & acid, relatively difficult to machine |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon (PA6 & PA66) | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM (Delrin) | High stiffness, excellent thermal & electrical properties, relatively brittle |
CNC Machining Tolerances
Tolerances are not standardized across all processes and materials. The final tolerances on your
part depend on various factors, such as part size, design complexity, the number and size of
features, materials used, surface finish, and the manufacturing process employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas
that may need modification for better manufacturability.
| CNC Turning Tolerances | ||
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
| *Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing. | ||
Applications of CNC Turning
CNC turning serves a variety of industries, enabling the precise manufacturing of components for
specific needs. Here are some key sectors and their respective applications:
1. Transportation: CNC turning is integral to the aerospace,
automotive, mass transit, rail,
locomotive, military, and trucking industries.
It's used to create essential transportation equipment such as headnuts, gear blanks, bearing
blocks, levers, axles, and rotors.
2. Construction: The construction sector relies on CNC machining to
produce robust components
capable of withstanding heavy loads.
Bolts, screws, and fasteners made from stainless steel and aluminum are common CNC-machined
parts used for assembly and fastening purposes.
3. Vehicles: CNC turning services play a crucial role in
manufacturing various auto parts.
These include engine components like cylinder heads, connecting rods, and camshafts, as well as
transmission parts such as shafts and rings.
Suspension elements like sway bars, control arms, and tie rod ends, along with items like bushings
and bolts, are also produced using CNC turning.
4. Air Travel: The aviation industry heavily depends on CNC turned
parts for customizing and
fabricating probes, joint connectors, fasteners, as well as engine and aircraft components.
Many aviation parts are crafted from titanium due to its exceptional performance in extreme
temperature conditions.

FAQ's
Advantages of the Turning Process
The turning process offers several advantages, including:
1. Versatility in Materials: While primarily used for machining metals, turning can be applied
to a wide range of materials, including wood and plastics, making it a highly versatile process.
2. Excellent Tolerance: Turning can achieve exceptionally high tolerances, ensuring precision in
the manufactured parts. It is often used to add precise rotational features to components whose
basic shapes have been formed through other methods.
3. Short Lead Time: Turning is known for its quick turnaround time. The lead time, which is the
duration from order placement to final delivery, is significantly reduced due to the efficiency
of the turning process.
4. Skilled Operator Not Required: Operating a turning machine, particularly a CNC lathe, does
not demand highly specialized skills. Machinists can complete a defined training program and
obtain certification from accredited industrial training organizations to handle CNC lathes effectively.
5. Adjustable Material Removal Rate: Turning allows for flexible adjustment of material removal
rates. Lathes can operate at different speeds based on the material being machined and the
desired end product, providing greater control and adaptability in the manufacturing process.
