What Contract CNC Machining Services can We Provide for You?
We formulate a reasonable production process based on your drawing plan to ensure that you can get the parts you need as quickly as possible. The following are the high-quality CNC machining service items we can provide you.
We specialize in the milling of various materials and can produce parts with complex shapes. Our factory is equipped with a variety of milling tools, so whether it’s a single prototype or mass production of parts, we can ensure that the part has an excellent surface finish and tolerance control as low as ±0.005mm.
We can manufacture your perfectly round parts with exceptional rotational accuracy, from simple drive shafts and tubular parts to complex bearing journals and rotating assemblies. Diameter tolerance can be controlled within ±0.005mm. In addition, we can ensure fast delivery and more cost-effective costs.
We utilize high-speed CNC drilling technology to ensure the precise location and size of each hole. From micro hole machining to deep hole drilling, we effectively avoid problems such as burrs. We also provide you with automated tapping services to create precise and durable threads.
If standard drilling cannot meet your requirements, our CNC boring services provide you with extreme internal hole precision. We are very skilled at correcting casting hole defects or expanding existing hole sizes to achieve extremely high dimensional accuracy and excellent interior wall finish.
If you need tighter tolerances, we also offer you precision grinding services. We specialize in surface and cylindrical grinding of various alloy materials, ensuring that your parts have the flatness, parallelism, and mirror-grade finish (Ra 0.2 or better) required for critical mating surfaces.
For some parts with complex shapes, the production task cannot be completed due to the physical limitations of the tool. But don’t worry, our EDM service can solve this problem perfectly. With this process, we can machine sharp internal corners, deep narrow ribs, and intricate internal structures.
Our rapid prototyping service can accelerate your product development cycle. We provide fast, no-MOQ CNC prototyping services to help you verify your design before mass production. Additionally, we offer free DFM reviews to help you identify and resolve design issues in advance.
Precision and efficiency have always been your focus. And our 5-axis machining centers can access the workpiece from almost any angle and machine complex organic shapes in a single setup. This not only significantly improves the relative positional accuracy between features but also greatly shortens the machining cycle of precision components.

DSR's Complete Contract Machining Service Process
As for the specific customized processing? Below I will explain more about what you need to do to speed up the overall process and ensure that your parts can be machined and delivered faster.
Upload your CAD and drawing files to let us know the tolerances, threads, shapes, etc. required for your parts.
You need to choose the required materials from more than 50 types of metals and plastics, and tell us the manufacturing quantity, surface treatment options, and other additional conditions.
After we know all of your needs, our engineering team will evaluate the manufacturing price based on your solution, and this evaluation will be completed within 24 hours.
Once you are satisfied with the price, production will start according to the agreed payment method. We will choose the most appropriate machining technology according to the plan and complete the order tasks with high efficiency and high quality.
Contract CNC Machining Services with Strict Quality Control
DSR has a strict quality inspection process. Our professional quality inspectors will conduct quality inspections on each part, measure whether their dimensions meet specifications, and conduct analysis of defects to avoid similar problems in subsequent production. In addition, we have advanced measuring instruments, including CMM, digital micrometers, surface roughness tester, etc. Through these instruments, we can ensure that all parts can meet your needs.
Surface Finishing Options for Contract Manufacturing
DSR provides a wide range of surface treatment projects, and you can choose the appropriate process according to your production needs. And we can also further improve the quality of your parts through surface treatment.
Low cost and fast delivery. We remove sharp edges from parts to ensure they are safe and easy to use. This process can maintain the natural metallic texture and fine knife pattern after CNC machining, making it suitable for components that have no special appearance requirements and only focus on dimensional accuracy.
We will use the Bead Blasting process to process the knife pattern and give the parts a uniform, soft matte surface. At the same time, this process can not only improve the visual effect of the part, but also enhance the anti-slip performance of the surface of the part.
Through the polishing process, we can significantly reduce the surface roughness of the part, up to Ra 0.1μm or less. This makes the parts more aesthetically pleasing and reduces friction loss.
We create directional parallel fine lines on the metal surface through the brushing process, giving the parts a strong industrial texture. The parts processed by this process are both beautiful and practical.
We use electrochemical reactions to create a hard oxide film on the surface of the part, which can greatly improve its corrosion and wear resistance. In addition, we offer Type II for coloring decoration, and Type III for extreme wear-resistant environments.
Stainless steel cleaning and anti-rust process. This process forms a dense protective layer of chromium oxide on the surface of the part to prevent rust. The passivation process does not change the size or appearance of the part and and is very suitable for the medical and food industries.
The most cost-effective anti-rust solution for steel parts. We offer blue and white zinc, colored zinc and black zinc, and can perform trivalent chromium passivation to meet environmental requirements.
Nickel plating has extremely high hardness and chemical stability. Nickel-plated parts are wear-resistant, corrosion-resistant, and also have good electrical conductivity and weldability.
We can make your parts stronger and more durable through the powder coating process. They can achieve better impact resistance and weather resistance. And this process is ideal for components that require long-term wear resistance.
If you need to paint parts or give these parts a better surface quality, then the painting process is the best choice. We provide a variety of textures such as glossy, matte and soft-touch to meet your appearance design needs.
We use processes such as quenching, tempering, or carburizing to significantly alter the physical properties of metal parts. Whether to enhance the wear resistance of parts or to eliminate the internal stress of welded components, we can provide professional heat treatment solutions.
