While traditional machining involves a skilled machinist manually operating a machine to remove
or shape metal based on specifications from designers and engineers, CNC machining performs
the same metal cutting, drilling, milling, boring, grinding, and other metal forming and removal
functions with a crucial distinction — it employs computer numerical control rather than manual
operation.
Traditional machining relies on tools such as turn wheels, dials, switches, chucks, vices,
and cutting tools made of materials like hardened steel, carbide, and industrial diamond.
Measurements are taken to ensure accuracy. In contrast, CNC machining is automated and
code-driven, developed by programmers.
It delivers consistent precision from the initial cut to subsequent repetitions, making it suitable
for digital manufacturing and low-volume production. CNC machining's advantage lies in its
flexibility for revisions and alterations, accommodating modifications and different materials with
ease. While traditional machining retains its place, CNC machining has largely taken over in
manufacturing, fabrication, and industrial production due to its superior precision and automation.
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. | ||

Company Profile
FAQ's
1. Do you offer reverse engineering services or suggest cost saving measures?
We offer reverse engineering services, allowing us to extract design and engineering information
from a wide range of manufactured components. Our expertise goes beyond mere reproduction
– we can aid in designing your part, recommending optimal raw materials, and selecting the most
efficient machining protocols and finishing steps.
With the end-use of the part in focus, we often identify minor design adjustments, material
changes, or tolerance modifications that can potentially reduce the cost of your part without
compromising quality or performance.
2. Do you offer other services, like finishing, assembly, packaging, and logistical support?
From finishing processes to logistical support, we offer a complete suite of services to efficiently
and cost-effectively bring your parts from inception to completion.
Our capabilities encompass anodizing, plating, grinding, finishing, assembly, warehousing, packaging,
and just-in-time delivery. Our aim is to provide a one-stop, hassle-free production process, allowing
you to save time and money while concentrating on your core business.
3. How do I request a quote?
Requesting a quote from us is designed to be simple and hassle-free. Head over to our "Contact Us"
page and complete the brief web form. We'll inquire about your desired turnaround time, required
quantity, and provide space for a concise project description.
Additionally, you can effortlessly upload your drawing file. If you prefer communication via email,
phone, all the necessary contact details are conveniently available on our contact page.
4. What formats of the files can you accept?
We can accept most of the 3D file formats like SolidWorks
(.sldprt)/ ProE(.prt) / IGES(.igs) /
STEP (.stp). We can also use 2D drawing (.pdf) or AutoCAD (.dwg) for quote against the parts
with simple structure.
All the other files formats are not listed above but can be read in AutoCAD/ProE/SolidWorks/
will be also fine for us.
