Stainless Steel Parts Customization CNC Machining Multiple Parts CNC
Turned Components Manufacturer
CNC turning is a machining process that involves securing a rotating workpiece in a chuck or
collet while cutting tools are used to remove material, shaping the workpiece as desired.
This process is controlled by a computer numerical control (CNC) system, enabling precise
operations like turning, facing, threading, and grooving by moving the cutting tools along
multiple axes.
Product Details
CNC machining materials are generally grouped into three primary categories: plastics, soft
metals, and hard metals. This classification includes materials such as aluminum, bronze, copper,
ceramics, plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.
| 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
Parts produced by this type of machining are commonly found in the automotive, aerospace,
medical, marine, and hydraulic industries. Such as headers, housings, shafts, shells, knobs,
rotors, terminals, fittings, pistons, valve stems, and similar products.

FAQ's
1. Can you generate design sketches for me?
Although we don't provide an independent product design service, we
do conduct Design for
Manufacturing reviews for all approved orders. This involves partnering with our clients to
optimize their 2D and 3D drawings, ensuring better manufacturability, resolving design conflicts,
and minimizing production costs. Explore guidelines on how to prepare your CAD drawings for
manufacturing.
2. What tolerances can I achieve with CNC machining?
Our standard tolerances for CNC machining are set at 0.05 microns, providing precision suitable
for the majority of commercial and industrial applications. If your project requires even closer
tolerances, we welcome consultation to address specific requirements and ensure optimal results.
3. What are the advantages of CNC machining?
1. Rapid Prototyping: CNC machining excels in rapid prototyping, allowing for the quick creation
of prototypes to test and iterate designs.
2. Efficient Production: The ability to produce full-scale
production parts rapidly makes CNC
machining a time-efficient manufacturing process.
3. Precision and Accuracy: CNC machining ensures a high level of
precision and accuracy in
manufacturing, meeting tight tolerances for parts of various sizes.
4. Tight Tolerance Machining: CNC machining offers the capability
for tight tolerance machining,
ensuring the exact specifications of CNC parts are met consistently.
5. Flexibility: CNC machining provides maximum flexibility in terms
of production volume, pricing,
lead times, and the selection of materials and finishes for the manufactured parts.
