CNC Milling Service

CNC milling is one of the most popular types of CNC machining processes.In a CNC milling machine, rotating cutting tools move relative to the workpiece to remove material. The cutting tool ( the milling tool) is fixed on a spindle that can rotate. The rotation and movement of the spindle give CNC milling machines the ability to perform three or more axes milling operations.

Multi-axis CNC Milling allows parts with multiple surfaces to be machined quickly and easily. Parts requiring good flatness and accurate complex curved surfaces can be produced easily.

CNC Milling, perfect for custom milling, is widely adopted for low to medium-volume metal and plastic parts that require high strength and dimensional accuracy.

What Is CNC Milling

CNC Milling process

CNC Milling process

Successful high-quality milling is a combination of three elements:

  • 1. A cutter with many teeth and ideal sharpness for a material
  • 2. Spinning a tool at a high enough speed to process a material correctly
  • 3. An appropriate feed rate for advancing the chosen material through the process

CNC allows for extremely close control of these elements. Computer system reads design information directly from an engineer’s drawings or models, eliminating possibilities for error between design and production.

The CNC milling process takes directions in customized software codes such as NC code, G-code, and ISO code, all converted straight from a project’s CAM or CAD designs. The codes are then translated into the machine’s controls, which run along at least two axes (X and Y), in addition to the tool spindle running in the depth, or Z, axis. Some machining centers allow for controls on up to five unique axes.

CNC Milling Surface Finishes

SERVICE

ANODIZING

Anodizing is an electrochemical process that enhances metals' corrosion resistance, durability, and appearance, particularly aluminum.

BLACK OXIDE COATING

Get functional and aesthetic benefits in one with Black Oxide surface finishing. It's a matte black finish that also adds protection to metals, reducing corrosion and wear over time.

POLISHING

we enhance the visual appeal of components by providing a smooth and reflective finish with polishing services. Polished surfaces can also serve as excellent bases for coatings, providing better adhesion and a more uniform finish.

ELECTROPOLISHING

Electropolishing enhances the corrosion resistance of metal by removing impurities and creating a clean, passive surface.

BEAD BLASTING

We can effectively remove rust, paint, scale, and other contaminants from various surfaces using bead blasting. Get a uniform and matte finish on surfaces to enhance the aesthetic appeal of the material.

MEDIA BLASTING

We commonly use media blasting in restoration projects to clean and rejuvenate surfaces without causing damage. We can effectively remove years of grime, corrosion, or coatings from historical or vintage items.

NICKEL PLATING

A uniform thickness and smooth finish contribute to an aesthetically pleasing appearance and consistent protective qualities. We ensure our process results in materials that can withstand friction and abrasion for a longer lifespan. Trust our nickel plating service!

ZINC PLATING

The compatibility of zinc plating with various materials adds to its appeal, while its ease of application and established use make it a readily available option.

ELECTROLESS NICKEL

DEZE offers electroless nickel plating with adjustable hardness levels, can be engineered to be non-magnetic, adheres tightly to substrates, and the thickness is precisely controllable.

HEAT TREATMENT

Improve the physical and mechanical properties of materials through heat treatment. Improve hardness, increase strength, enhance toughness, stress relief, and more.

LASER MARKING

We provide high precision and accuracy, enabling intricate designs, fine details, and small text to be marked clearly on a wide range of materials, including metals, plastics, glass, ceramics, and more.

POWDER COATING

Get a resilient finish that is resistant to chipping, scratching, and fading. Powder coating is your low-cost, eco-friendly finish that has long-term benefits, including reduced maintenance and enhanced longevity

PVD COATING

We offer a wide range of decorative finishes with PVD coating, including various colors and aesthetic effects. This process can also make materials more resistant to wear, abrasion, and scratching.

PASSIVATION

We form a thin, inert layer on the material's surface that protects it from environmental factors that could lead to corrosion. Passivation is commonly used in metals like stainless steel and aluminum.

What are the advantages of CNC milling?

  • 1. High Precision and Consistency - CNC milling achieves very precise tolerance control, ensuring consistency in parts.
  • 2. Efficient Production - CNC milling increases production efficiency and speed through automation.
  • 3. Complex Geometry Processing - Capable of handling complex shapes and designs, including using multi-axis machines for more intricate machining.
  • 4. Diverse Materials - Can work with a variety of metals, plastics, composites, and more.
  • 5. Reduced Waste - Precise material cutting reduces waste.
  • 6. Automation - Reduces the need for human intervention, lowering labor costs and improving quality control.
  • 7. Flexibility - Easily adapts to design changes and is suitable for a wide range of applications.
  • 8. Surface Quality - Provides good surface finish, which can be further enhanced if needed.

These features make CNC milling an ideal choice for manufacturing high-precision parts across various industries.

What Is the difference between CNC Milling and Turning?

SERVICE

CNC Milling is mainly realized by rotating and moving the tool on the surface of the workpiece and is often used to process flat, curved surfaces and complex shapes of parts, such as gears, molds, parts shells, and so on.

CNC Turning is mainly realized by rotating the workpiece and cutting with the tool on the workpiece and is often used to process cylindrical-shaped parts, such as shafts, bearings, threads, etc.

Turning and Milling Similarities

Both processes, turning and milling, use subtractive manufacturing to remove unwanted material, producing waste chips. They differ in stock material, machining methods, and tools but both utilize advanced CNC technology. Engineers program the machines using CAD software, reducing supervision and minimizing human error, which enhances speed and reliability for consistent quality.

Turning and milling are suitable for metals like aluminum, steel, brass, copper, and titanium, as well as various thermoplastics. However, they are not suitable for materials like rubber and silicone (too soft) or ceramic (too hard).

Both techniques generate heat and often use cutting fluid to manage this issue.

Knowledges

Investment Casting usually uses investment materials (low melting point materials such as wax, etc.) to make molten molds and form molds, and then coats the mold surface with several layers of refractory materials.
In mold factories, CNC machining process is mainly used for the processing of mold cores, inserts and other key mold parts and copper cores. The quality of mold cores and inserts directly determines the quality of mold forming parts.
Metal polishing can make the metal surface smooth and flat, removing particles, oxide scales, flaws, etc. on the surface, thereby enhancing the overall appearance quality of the material
