CNC Milling Parts Machining Service CNC Machining Custom Mechanical Parts
In the realm of metal fabrication, milling stands out as the most prevalent method for
material removal.
CNC milling machines, renowned for their exceptional precision and accuracy, find extensive
application in cutting an array of metals.
The outcome of milling can vary depending on factors such as the material's type, strength,
and hardness.
Certain metal alloys, like titanium, exhibit exceptional durability and can withstand demanding
environments.
Other noteworthy metal alloys encompass aluminum, copper, brass, zinc, bronze, stainless steel,
and steel. Metal milling encompasses processes such as shaping, cutting, drilling, and tapping.
Product Details
CNC milling encompasses a wide range of materials, with three main categories:
plastics, soft metals, and hard metals.
These materials are versatile and suitable for various machining applications.
Examples of materials used in CNC milling include aluminum, bronze, copper, ceramics,
plywood, various types of steel, stone, wood, and zinc, among others.
Certain materials, such as aluminum and mild steel, are favored by machinists due to their
ease of workability and excellent properties, making them industry standards for many applications.
| Common Materials for CNC Machining | |
| Material | Properties |
| Aluminum | 2024: Good fatigue resistance and strength; excellent toughness at moderate to high strength levels; improved fracture toughness |
| 6061: Excellent machinability, low cost, and versatility | |
| 7075: High strength, hardness, low weight, and heat tolerance | |
| Stainless Steel | Excellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability |
| Steel Alloy | Mix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength |
| Brass | Versatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive, and medical industries |
| Copper | High ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM | High stiffness, excellent thermal & electrical properties, relatively brittle |

Company Profile
FAQ's
1. What are the minimum and maximum dimensions you can machine?
We offer a wide range of CNC machining services, including CNC milling (3-axis, 3+2-axis, and 5-axis)
and turning.
When it comes to milled parts, our capabilities extend to dimensions of up to 2000 x 1500 x 200 mm
(78.7 x 59.0 x 7.8 in.) for 3/3+2 axis CNC milling, while for 5-axis milling, the maximum part
size accommodated is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
For CNC turning, we can handle parts with a maximum diameter of 431mm (17 in.) and a length of
990 mm (39 in.).
On the smaller end, we recommend minimum part dimensions of around 0.39 x 0.39 x 0.39 inches
(10 x 10 x 10mm), with a minimum feature dimension of 0.5 mm.
Please note that our platform has a size limitation of up to 1000 mm (39 in.) for parts.
If you require larger dimensions, you can submit a request through our sales team for further
assistance.
2. What cosmetic standards do you guarantee?
Our commitment to quality ensures that deburring and edge breaking are standard procedures for
all CNC machined parts.
In cases where there are specific edges that need to remain sharp, it is crucial to clearly specify
them in the technical drawings.
Furthermore, we guarantee that the surfaces of the machined parts will be free from any defects,
including but not limited to scratches, dents, stains, blemishes, and hanging marks.
Surfaces that are designated as critical, especially the primary (a) side as indicated in the technical
drawing, will be completely free from any mill steps or other marks.
For the secondary (b) side, minor hanging marks and up to 2 minor defects are within acceptable
limits. Our commitment to delivering high-quality results extends to post-processing and finishing
methods that can be employed to enhance surface roughness, improve visual properties, and
increase wear resistance for machined parts.
3. How long does delivery time and quotation take?
Our delivery time and quotation process are influenced by the complexity of your project.
For low-complexity parts, expect a lead time of 2-3 days. As complexity increases, the lead time
can range from 2-5 days. High-complexity parts may require a lead time of 5-15 days.
Quotation turnaround time varies based on complexity as well. For straightforward designs, we can
provide a quote within 1 business day or even faster. However, for more intricate projects,
the quoting process may take 3 or more business days.
If you have a design that needs assessment and a quote from our team, please don't hesitate to
contact us.
