Custom Parts Manufacturing
If you require customized precision machining services, EVERGREEN is the ideal partner for you. With our professional expertise, extensive experience, and advanced skills, we are committed to becoming your most competitive supplier, particularly in terms of professionalism and cost-effectiveness. We strictly adhere to the ISO 9001 quality management system standards, combined with efficient production processes and flexible customization services, enabling us to deliver complex projects on time and provide products of the highest quality.
We can also provide some common surface treatments for your parts, such as sandblasting, shot blasting, polishing, electrophoresis, powder coating, and spray painting.
Prototype CNC Machining
Before manufacturing your customized parts, CNC prototyping is an effective method for validating complex designs and conducting pre-production testing. It helps us identify and resolve issues in a timely manner, ensuring that parts can smoothly transition into mass production.
In the early stages of the project, we will implement precise and cost-effective manufacturing processes to produce high-quality prototype parts for you. Our team of engineers will review and verify every project, analyze your design, and meet any special requirements, such as combinations with welding, EDM, or wire cutting processes. This is the only way to ensure you receive the optimal manufacturing solution.
Materials Suitable for Processing
Aluminum Alloy
Aluminum alloys are lightweight but have strength comparable to steel, making them ideal for use in the automotive and aerospace industries to achieve weight reduction. They also have excellent machinability.
Stainless Steel
The corrosion resistance, high hardness, and high wear resistance of stainless steel make it ideal for applications in industries such as medical devices, marine equipment, and precision bearings, including surgical forceps and chemical valves.
Titanium Alloy
Titanium alloys have exceptional hardness and extremely low weight, and are also resistant to high temperatures and corrosion, making them the material of choice for the aerospace and deep-sea industries.
Copper
Copper has extremely high processing efficiency and a surface finish of Ra0.8μm, making it ideal for small gears. At the same time, copper also offers excellent electrical conductivity and wear resistance.
4 Steps to Improve CNC Part Dimensional Stability
Eliminate material stress
Common methods for eliminating material stress are natural aging or vibration treatment. EVERGREEN first performs rough machining on the parts, then leaves them to age naturally for 2-3 hours before performing precision machining.
Improve the workpiece clamping method
Traditional three-jaw chucks can cause part deformation if the clamping force is uneven. In such cases, we typically switch to hydraulic expansion fixtures or vacuum suction platforms. For irregularly shaped parts, we also develop custom-designed soft jaws.
Improve cutting tool performance
The material and geometric parameters of cutting tools have a significant impact on machining accuracy. Selecting the wrong tool can also cause cutting vibrations, which have an even greater impact on accuracy. Therefore, selecting the correct tool is a critical step in the process.
Choose a reasonable machining process
EVERGREEN’s processing workflow generally consists of rough machining, semi-finishing, corner cleaning, cooling, and finishing. Cooling is an important step, as failure to cool can easily lead to heat accumulation and dimensional instability. For parts with high precision requirements, the number of semi-finishing steps needs to be increased.

Applications
The primary functions of rail vehicles are high speed, safety, and comfort. Therefore, the internal components of rail vehicles cannot function without the support of precision machining. For example, the gearboxes and suspensions inside the bogies of high-speed trains directly affect wheel alignment, requiring large-scale precision five-axis machining centers to ensure accuracy. Additionally, the machining accuracy of rail wheels directly impacts the smooth operation of trains.
In the construction machinery industry, some machinery and equipment face extremely harsh working conditions every day, including high impact and high vibration. This not only requires the materials used to manufacture parts to be of high quality, but also places extremely high demands on the precision of internal core components. For example, in hydraulic systems, even slight dimensional deviations in certain parts can lead to internal leakage, affecting high-pressure sealing and energy conversion. As a result, many internal core components require precision machining, grinding, boring, and EDM.
In the medical equipment industry, precision parts are indispensable. Some imaging equipment, such as CT and MRI rotating frames, slip rings, and precision bearings, require extremely high processing accuracy to ensure clear imaging without artifacts. We not only manufacture precision-machined equipment for the medical industry, but also produce sheet metal products, such as equipment cabinets.
