CNC machining, an abbreviation for Computer Numerical Control machining, operates as a
subtractive manufacturing technology, autonomously removing material from raw stock guided
by computer-generated instructions.
Generally, CNC machines can be classified into two types: those that keep the raw stock stationary
while rotating the cutting tool, and those that rotate the raw stock while moving it against a
stationary tool.
Various modifications and combinations of these fundamental approaches are employed, allowing
some machines to integrate both techniques for the production of intricate parts with complex
features.
Product Details
The turning process primarily involves the machining of various metals.
These metals encompass a wide range of materials, including alloy steel, carbon steel, cast iron,
stainless steel, aluminum, copper, magnesium, and zinc.
Nevertheless, it is essential to note that the turning process is not limited to metals alone;
it can also be applied to plastic components and a diverse array of materials such as ceramics,
composites, thermoplastics, and thermosetting materials.
| Common Materials | |
| Name | Description |
| Aluminum | High machinability and ductility, good strength-to-weight ratio. |
| Stainless steel | High tensile strength, corrosion and temperature resistant. |
| Mild steel | High machinability and weldability, high stiffness. |
| Brass | Low friction, excellent electrical conductivity, golden appearance. |
| Copper | Excellent thermal and electrical conductivity. |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
| POM | High stiffness, high accuracy, low friction, easy to machine. |
| ABS | Common thermoplastic, impact resistant, easy to machine. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
CNC Machining Tolerances
Typical machining tolerances fall within the range of ± 0.005 inches or 0.13 millimeters.
Tolerances represent the allowable variation for a specific dimension.
For instance, if a CNC machining tool has a tolerance of ± 0.01 millimeters, it means that the tool
can deviate by 0.01 millimeters in each cut.
When provided with a drawing, Our CNC machining service can achieve CNC parts with tolerances
as tight as ± 0.0002 inches.
In the absence of a drawing, all CNC parts are manufactured according to our ISO 2768 medium
standard. We can also work to even tighter tolerances, such as ± 0.025 millimeters or ± 0.001
inches, when an engineering drawing specifies critical features.
| 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
The utilization of CNC machining spans a multitude of industries, with a significant presence in
aerospace, automotive, consumer electronics, robotics, and agriculture, particularly in the
production of metal components. Beyond these, CNC machining is integral to the manufacturing
processes of medical devices, household goods, and various consumer applications.
Its prevalence extends into sectors such as energy, oil and gas, making CNC machining one of the
most pervasive and essential manufacturing techniques globally.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our comprehensive CNC machining services cover milling (3-axis, 3+2-axis, and 5-axis) and
turning processes. In 3/3+2-axis CNC milling, we can achieve part dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.).
For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
CNC turning accommodates a maximum diameter of 431 mm (17 in.) and a length of 990 mm
(39 in.). Smaller parts are recommended to have dimensions around 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), with a minimum feature size of 0.5 mm.
It's important to be aware that our platform imposes a maximum part size of 1000 mm (39 in.),
and for larger requirements, we encourage you to contact our sales team for tailored support.
2. What's the general surface texture of CNC milled and turned parts?
The surface texture of machined milled parts is commonly around 3.2μm (or 1.6μm for more recent
machines). In the case of turned parts, a finer surface finish is achieved, reaching a roughness of
0.8μm. Notably, this enhanced surface texture in turning is accomplished without the necessity of
adjusting machining speeds.
3. What are you shipping terms?
In our standard shipping terms, we utilize Ex Works (EXW) for both rapid prototyping and regular
production orders. This means that once the goods depart our premises, the customer is responsible
for shipping, customs clearance, and all related fees.
Express shipments follow the Delivered Duty Unpaid (DDU) arrangement, where the client takes on
the responsibility of paying import duty upon the goods' arrival at the destination.
