What Is CNC Drilling
CNC drilling is a core process in CNC machining used to create precise holes in various materials such as metal, plastic, and wood. This technique is essential in the manufacturing of parts that require accuracy and precision in hole placement. CNC drilling is often combined with milling and turning to produce parts that need both holes and other machined features.
Drill parts typically feature multiple holes, which are common in components like flanges, housings, or other parts that require fasteners, shafts, or channels. The combination of drilling with milling or turning allows for greater versatility in manufacturing, enabling the creation of complex components with high tolerances and precision.
This process is highly valuable in industries that require intricate parts, such as aerospace, automotive, and electronics, where the alignment and diameter of holes are critical to the overall functionality of the components.

Materials and Diverse Coatings For CNC Machining
Your CNC machining services are suitable for a wide range of materials, from metals to plastics. Based on your requirements, Sundi offers more than 50 production-grade materials to choose from. Below is a list of the materials most commonly used in our CNC machining process. You can also contact us to discuss your specific needs.
Aluminum
It is the most widely used non-ferrous metal structural material in the industry. As a soft, lightweight, and durable metal material, it is often used in aerospace, automobile, machinery manufacturing, shipbuilding, and industrial development. Customized aluminum products have a wide range of appearance and color options and a complete range of surface treatments, which can meet the needs of different industries.
Stainless Steel
SUS stands out for its impressive strength and corrosion resistance. However, its toughness presents a challenge in machining. It is predominantly used in the medical field for surgical and diagnostic equipment, in food processing machinery due to its non-reactive nature, and in automotive components for durability.
Copper
Copper is another favored material, particularly for its superior electrical and thermal conductivity, paired with ease of machining. This makes it perfect for electrical wiring components, heat exchangers, and decorative items, where conductivity and aesthetic appeal are required.
Tool Steel
This kind of material is known for its exceptional performance and durability, and mo re efficient when precision grind for exact dimensions and surface quality,making it ideal for cutting tools, molds,and CNC machining parts.
Nylon and ABS
These are chosen for their lightweight and flexibility, though they are not suitable for high-temperature applications. Their use is widespread in consumer electronics for non-critical parts and for creating prototypes due to their ease of machining and cost-effectiveness.
Carbon Fiber and Composite Materials
They are often the go-to options. While they offer an excellent strength-to-weight ratio, their machining process can be complex. These materials are widely used in aerospace for structural components, in automotive for high-performance parts, and in sports equipment for durability and weight reduction.
Diverse coatings significantly enhance CNC machined parts，like resistance to corrosion and wear but also enhance their visual appeal. The choice of coating depends on the environmental conditions and functional requirements of the part, ensuring optimal performance and longevity.
Anodizing
Primarily used for aluminum parts, anodizing enhances corrosion and wear resistance while also improving appearance. It allows for a range of color options, making it ideal for both functional and decorative applications. Thickness : Typically ranges from 5 to 25 microns，This coating can be customized for thicker layers in certain applications
Galvanizing
Applied mainly to steel components, galvanizing provides excellent protection against corrosion. It can be implemented through electro-galvanizing or hot-dip galvanizing, depending on the application requirements.
Thickness : Around 5 to 15 microns，Generally ranges from 45 to 75 microns, providing a thicker and more durable protective layer
Nickel Plating
Offers robust corrosion and wear resistance, commonly used in automotive and electronics components. Nickel plating also improves surface hardness, extending the lifespan of the parts.
Thickness : 5 to 500 microns, depending on the required wear resistance and application
Chemical Conversion Coating
This includes chromate coatings on aluminum, enhancing corrosion resistance and preparing the surface for further painting or coating. It's essential for parts exposed to harsh environments.
Thickness :Usually between 0.5 to 5 microns. While thin, this coating effectively protects against corrosion and prepares surfaces for painting
Powder Coating
Known for its tough, durable finish, powder coating is applied to a variety of metals. It enhances both aesthetics and corrosion resistance, suitable for parts requiring a high-quality surface finish.
Thickness :Generally between 40 to 80 microns. This thicker coating provides a robust and durable finish, suitable for a variety of applications
Black Oxide
Used on iron and steel, black oxide provides a certain level of corrosion resistance and reduces light reflection. It’s often used for parts where a matte black finish is desirable.
Thickness : Typically around 0.5 to 5 microns. This relatively thin coating mainly provides an aesthetic finish and some corrosion resistance
Hard Coating
Such as tungsten carbide coatings, which are used to significantly increase wear and scratch resistance. Ideal for parts in high-abrasion environments, ensuring longevity and durability.
Thickness:range of 2 to 10 microns. It is tailored to provide maximum wear resistance for specific applications
Chrome Plating
Often utilized for its decorative and corrosion-resistant properties, chrome plating offers a bright, shiny finish and good hardness. It’s popular in automotive and decorative applications.
Thickness :
- Decorative Chrome Plating Thickness: About 0.5 to 20 microns.
- Hard Chrome Plating Thickness: Ranges from 20 to 50 microns or more, providing a durable surface for wear-prone applications
