What is CNC machining?

CNC machining is a process that uses computer control to shape metals. The process accurately cuts and shapes plastics too. It relies on a pre-designed model code for precise cutting and manufacturing. Allows the production of complex parts and reduces the probability of risk from human intervention. With the advantages of high precision, high repeatability and high efficiency, it is now widely used in modern manufacturing.

Principle of Machining

The principle of CNC machining realizes a highly automated precision manufacturing process by converting digital information into physical movement. The main process consists of: designing the model – writing the program – setting up the tool path – uploading the program – machining. Each step of the process is closely coordinated to perform accurate material cutting and molding.

CNC Machining Surface Finishes

The fastest solution for turnaround is to machine the parts. Machining produces tool marks, sharp edges, and burrs. By default, we remove them. If you need to keep sharp edges and burrs, please make a note in the 2D drawing. Surface finish equivalent to 125 in Ra. Suitable for metal and plastic processing.

Sandblasting + anodizing is often used for the surface treatment of machined aluminum parts. Anodizing is a process that finishes parts in various colors. The common colors include transparent, black, red, and gold. With sandblasting, a smooth, matte appearance can be achieved.

Metal parts can be treated using anodizing to create various colors. Commonly used colors are clear, black, red, and gold. Additionally, this treatment enhances the surface’s resistance to corrosion. This enhances the life of the part.

The conductive oxidation process generates a thin, corrosion-resistant oxide layer. This layer has a film thickness of about 0.01-0.15 microns. The layer is conductive but not wear-resistant. They are commonly used in electronic components and other conductive industry parts processing.

Black oxide is a type of coating that is applied to steel or stainless steel. It is used to improve the appearance and prevent corrosion. It is a common metal surface treatment. The process is used to make parts for different industries. These include automotive, mechanical, and decorative processing.

Brushing is a method that adds texture to metal parts. It enhances the metallic texture of the product. This method is commonly used in home furnishing and appliance industries.

The surface of a part is cleaned and smoothed to give it a matte, smooth appearance

We offer both high-gloss and matte paint spraying options. A high-pressure spray gun applies paint evenly in small droplets. Surface treatment is common. It is used in smart hardware, home appliances, and plastic parts.

Metal parts are coated with powder coating by electrostatic spraying. This creates a durable coating that resists abrasion and corrosion. The coating comes in high-gloss and matte color choices, similar to spray paint. Widely used in metal products, furniture, automotive parts and other industries.

Electroplating adds a nickel coat to metal parts, protecting against corrosion, oxidation, and wear. The coating starts at a thickness of 0.001. Primarily used in industries such as automotive, aerospace, electronics and medical devices.

Parts are machined with high precision to reduce surface roughness. The standard smooth surface roughness is Ra 1.6 μm (64 μin). The main purpose is to machine surfaces of precision machinery, optical instruments, and medical device parts.

Electrochemical polishing removes excess surface, making parts brighter and smoother. It removes approximately 0.0001″-0.0025″ of metal. Meets ASTM B912-02

It enhances the rust protection of 200 and 300 series steels. It also improves the corrosion resistance of precipitation hardening steels. Negligible thickness, approximately 0.0000001″. Conforms to ASTM A967, AMS-QQ-P-35, MIL-STD-171, ASTM A380, or AMS 2700.

The maximum part sizes differ based on the chosen material. The biggest sizes are for machined aluminum parts (6061 and 7075), as well as milled parts up to 80 x 48 x 24 (2,032 x 1,219 x 610 mm). Turned parts are available in lengths up to 62 inches (1,575 mm) and diameters up to 32 inches (813 mm). If you need larger dimensions, you can contact our engineers online.

We guarantee that all the parts we supply conform to ISO 2768. Machined metal parts conform to ISO 2768-m (medium) or ISO 2768-f (fine). Machined plastic parts comply with ISO 2768-m (medium). Depending on the customer’s needs, we are also able to realize even more demanding CNC tolerances.

Deburring and edge breaking are standard procedures for CNC parts machining. The surface finish standards will strictly follow the set drawings. The drawings will have marks/symbols/specific values to represent the standards. This will ensure that the part meets the specifications.

The factors that impact CNC machining costs include production time, part complexity, machining accuracy requirements, surface treatment, coating, and materials.

The most effective way to reduce machining time is by designing parts that can be machined quickly.

Reducing complexity is possible by splitting complex parts. The parts can then be machined separately and assembled later.

Apply additional surface treatments only where necessary. This can increase manufacturing costs for your part.

When choosing materials for a job, opt for softer metals. Soft metals are easier to machine, which reduces material waste and saves costs.
