CNC Milling Parts Stainless Steel Aluminum CNC Parts Precision Rapid Prototyping Services
CNC (Computer Numerical Control) milling is a common machining technology used to produce complex metal or non-metal parts. The characteristics of CNC milled parts can be described from many aspects, and the following are some of the main characteristics:
Shape and complexity:
CNC milling can produce parts with very complex shapes, including three-dimensional surfaces, special-shaped holes, cavities and grooves.
It can produce complex geometric shapes that are difficult to achieve with traditional machining methods.
Dimensional accuracy:
CNC milling machines have high positioning accuracy and repeatability, and can process parts with high dimensional accuracy requirements.
Usually, an accuracy of ±0.005 mm (±0.002 inches) or higher can be achieved.
Surface finish:
The surface finish of the milled parts is high, sometimes even mirror-like.
Surface roughness (Ra value) can reach 0.4 microns or less.
Material diversity:
CNC milling can process a variety of materials, including various metals (such as aluminum, steel, stainless steel, titanium, etc.), plastics, wood and composite materials.
Consistency of mass production: CNC milling machines can continuously produce a large number of parts of the same specifications with high consistency. Reduced manual operation errors and improved production efficiency. Processing efficiency: CNC milling can usually set up and switch programs quickly, which is suitable for multi-variety and small-batch production. High degree of automation, reduced manual intervention and improved processing efficiency. Versatility: CNC milling machines are usually equipped with a variety of tools, and can complete a variety of processing operations on the same machine, such as drilling, tapping, countersinking, milling slots, etc. Reduced material waste: CNC milling can remove material accurately and reduce material waste. Material utilization can be further improved by optimizing tool paths and fixture design. Design flexibility: CNC milling allows designers to be more innovative in the design stage, because almost any imaginable shape can be achieved by CNC milling. Post-processing requirements: Due to the high precision and good surface quality of CNC milling, parts usually require less post-processing work. However, for some applications, subsequent finishing, heat treatment, surface treatment and other steps may still be required. These characteristics of CNC milling technology make it an indispensable processing method in the manufacturing industry, especially in the production of high-precision and complex parts.

Q1: What kind of CNC machining services do you offer?
A1: CNC machining is also known as computer numerical control machining. We offer the following machining services: milling, turning, drilling, threading, tapping, EDM and wire-cutting, custom surface treatments, prototyping, small batch or single-use parts machining.
From prototype to production, from 1 to 10,000 pieces, we offer fast turnaround CNC machining for your custom metal and plastic parts, the fastest delivery time can be within 3 days.
Q2: What are your CNC machining capabilities?
A2: We have 3000 square meters of CNC machining workshop. With 60+ skilled employees and more than 20 high-performance CNC machines, it maintains 24/7 operations and can deliver more than 400 machining projects and 30,000+ machined parts per month.
Q3: What is the cost of CNC machining parts?
A3: Our engineering and sales teams will provide one-to-one quote support for your project. In general, for similar parts, the machining cost of CNC lathes is 15% lower than that of standard 3-axis CNC milling. In contrast, the cost of 5-axis machining increases, and the cost of 5-axis linkage milling is higher than that of a 5-axis machine (also known as 3+2 milling) by 20%, about twice as much as a standard 3-axis milling machine.
Q4: What is the maximum size range of your machine travel?
A4: Max size of the 3-axis milling is 1500×808×635(mm); Max size of the 5-axis milling is 1016×635×635(737)(mm),Work table diameter is Φ635 mm .
Q5: What kind of surface finish does CNC machining leave behind?
A5: After machining, there are slightly tool marks on the part surface which is called “machining marks” or “milling marks” surface finishing. The standard machining surface roughness(Ra) is 1.6-3.2μm. We can improve to 0.8-1.6μm or better 0.2-0.8μm but it takes more operation time and cost.
