Compared with the general milling machine, DF's CNC Machine Center has two prominent features in the structure. One is the linkage of coordinates, that is, it can coordinate actions in multiple coordinate directions at the same time, and maintain the predetermined mutual relationship, so as to control the tool to move along the set line, arc or space line, arc trajectory. CNC milling machine can realize two-axis, three-axis, four-axis, or five-axis linkage. The second is the spindle control. The start and stop of the spindle, forward and reverse rotation, spindle speed change, etc. can be automatically executed according to the program. In general, our machine has the following advantages:
It can process parts with complex shapes and sizes, such as mold parts;
It can process the parts that need to be processed in multiple processes after one clamping and positioning;
It has higher machining accuracy and can guarantee stable and reliable quality;
It has higher production automation which can improve production efficiency.
Compared with other manufacturing processes, CNC milling has several advantages. It is cost-effective for short-term operation. Complex shapes and high dimensional tolerances are possible. Smooth surface treatment can be achieved. NC milling can produce almost any 2D or 3D shape as long as the rotating tool can reach the material to be removed. Examples of parts include engine components, molds, complex mechanisms, housings, etc.

Our CNC Milling Services
Every drawing is checked and programmed by our engineers. We accept 2D drawings in PDF or DWG, DXF, 3D STP, and IGS formats.
Use ERP system to manage drawings and production, high efficiency, avoid mistakes.
Each material is carefully selected from the supplier. DF uses a material analyzer to test materials.
Each size is repeated. DF controls the dimensions within the tolerances provided on the drawings. Provide sample quality inspection reports for customers.
Each order is delivered at the specified time. DF accepts the transportation mode required by customers.
DF's processing services are based on quality. Its goal is to provide customers with reassurance and satisfaction
As the finishing process will affect the surface finish (thus affecting the part size), we do not recommend the application of secondary finishing on high tolerance parts, because the finishing process may remove or add enough materials to make the finished parts exceed the dimensional tolerance. DF provides the following secondary processing for your machining and sheet metal processing parts.
Chemical film coating: also known as chemical conversion coating, chromate coating or zinc coating, aluminum or nickel coating. The surface produced by this process has corrosion resistance, durability, and stable conductivity.
Anodizing: anodizing is an electrochemical process that transforms aluminum (usually aluminum) into a decorative, durable, corrosion-resistant anodized surface.
Powder coatings: textured powder coatings (spandex polyester and textured polyester) will cover tool marks without additional surface treatment.
Texture finish: deburring and scraping parts with a brush/sander to create a specific texture. It is ideal for parts where a uniform nude finish is necessary, but powder coating is not ideal.
Due to the geometric shape, grain size finishing can only be applied to the outer surface of parts processed by numerical control and sheet metal, but not to the inner surface of parts.
Non-textured coatings (smooth polyester, smooth epoxy, and smooth polyester epoxy) will not cover tool marks by themselves. Therefore, an additional finishing operation, such as grain size finishing, needs to be performed.
Number printing: This is Ideal for branding (such as your logo), label connectors and switches, and decorative purposes (silkscreen can also be used as an alternative to digital printing).
Machining engraving: This is a permanent form of marking, very suitable for labeling, branding, or schematic. Also known as etching, machining, engraving can be done with powder coating, paint, particle finishing, anodizing and chemical film chromate coating, depending on the material.

Titanium Alloy Parts
If you have titanium parts in the process, we are one of the most capable and affordable sources. Let’s first talk about the following 3 questions:
What are the advantages of titanium?
Which titanium is more popular?
What are the main uses of titanium?
Titanium is new metal. It has many remarkable advantages over other metals.
High strength: Titanium alloy density is generally 4.51g / cubic centimeter, only 60% of steel, pure titanium density is close to the density of ordinary steel, so titanium alloy specific strength is much larger than other metals.
High heat strength: Titanium alloy operating temperature can be up to 500 ℃, while aluminum alloy has to at 200 ℃.
Good corrosion resistance: Titanium has good corrosion resistance to alkali, acid, salt, etc.
Good Low-temperature performance: Titanium can still maintain its mechanical properties at low temperature and ultra-low temperature.
Some of the most popular titanium alloys are as follows: Gr1-4, GR5, GR9, etc.
