Customize CNC Machining Parts Solution For Your Project
The name of CNC is computer numerical control machining, which is one of the most precise manufacturing processes currently used for machining parts. It is a subtractive machining method, whereby a block of material is repeatedly removed to create a finished part. This high-precision machining process relies on G-code—a program that precisely dictates machining steps to within fractions of a millimeter. CNC machines execute these commands with minimal human intervention, guaranteeing exceptional accuracy.

Typical CNC Manufacturing Parts and Their Applications
DSR can provide you with a variety of parts and customized machining solutions according to your needs. The following are our most popular CNC machining parts types. If you have any special needs, contact us now, we are ready to provide services for you at any time.
Housings & Enclosures are the most common CNC machining parts in the electronics and industrial industries. They are typically manufactured using CNC milling and turning to achieve high-precision housings, and can also achieve extremely high waterproof ratings through surface treatment.
Brackets and mounts are common features in automation and mechanical equipment areas. They always require exceptional strength and load bearing capacity. DSR is usually milled to a tolerance of ±0.01mm to ensure its installation accuracy.
Fixtures and jigs are commonly used in manufacturing. They are positioning plates and extremely small positioners, which provide accurate positioning for other components and ensure the accuracy of the finished product. After our CNC manufacturing, fixtures and jigs have higher accuracy and provide higher positioning accuracy.
Gears are one of the most representative parts of CNC machining and are also the most common parts in the mechanical industry. They require extremely high dimensional accuracy to achieve a high degree of meshing, and some also require extremely smooth surfaces, which can only be achieved with multi-axis CNC machining machines.
Shafts are one of the core components in the industrial field and are also representative parts of CNC turning manufacturing. Through our CNC machining services, your customized shafts can strictly meet or even exceed high tolerance requirements. From small to large, conventional and threaded shafts can all be achieved through CNC machining.
Valves are used in many fields, but require CNC machining are usually small valves, such as hydraulic valves and pneumatic valves. These valves require smooth inner cavities and high-precision threads, and CNC machining ensures good sealing and reliability.
Heat sinks are particularly common in the field of electronic equipment. They have extremely high requirements for continuous surface manufacturing, and heat dissipation fins also have special designs. Therefore, their complex heat dissipation structures are usually achieved through our milling process.
Medical instrumentation components include shafts, torque shafts, pull wires, and various nickel-chromium components. Due to the special nature of medical equipment, these components require extremely high precision and must meet relevant standards.

Multiple Quality Inspections We Have
When your manufacturing is complete, we will use a 3D Coordinate Measuring Machine to test the dimensions, geometric accuracy, and tolerances of the parts to ensure that each of your customized CNC manufactured parts fully complies with the design and standards. If you need, we can also provide pressure, airtightness, and hardness testing through our Electronic pneumatic meter and Rockwell hardness tester.
Multiple Processes Deliver High-Precision CNC Machining Parts
CNC machines typically use a variety of machining processes when machining your custom parts, such as turning, milling, and more, each of which has unique characteristics.
CNC turning is a manufacturing process in which a bar is clamped and then rotated to remove material. Typically, a turret (shown in the center) moves to the specified bar location for processing. It is also a representative process of CNC as a subtractive manufacturing process. After processing, the material can be formed into squares, hexagons, and other symmetrical shapes, but it is most commonly used for circular workpieces.
Milling is a mechanical manufacturing process that selectively removes material from a piece of raw material. Our composite CNC machining centers typically have more than 5 independent axes of motion, enabling us to manufacture complex parts. Whether the parts have been manufactured or not, we can provide you with the specified shape through CNC milling and ensure high precision.
Drilling is an essential process for machining parts, especially for parts with holes such as pipes and valves. Through a computer to control the drill bit, it is possible to achieve a level of precision and consistency that cannot be achieved by manual operation. This is particularly suitable for industries with extremely high precision requirements, such as automotive, electronics, and aerospace.
As the main process for threaded part manufacturing, tapping is primarily responsible for the internal threading of parts. This is an efficient and simple threading process, especially when you order large quantities of screws (they can also manufacture nuts). Our CNC equipment is usually equipped with manual taps and power taps.
The Various Surface Treatment DSR Deliver
We offer a variety of surface treatments, each enhancing the corrosion resistance and precision of your custom CNC machined parts.
We have specialized grinding equipment that can achieve a tolerance of ±0.005mm on your custom CNC-machined parts.
Your custom machine parts may have edges that may show damage or manufacturing marks. Light sandblasting can smooth them out without affecting part accuracy.
Anodizing will create a ceramic layer on the surface of metal parts, enhancing the durability and corrosion resistance of CNC-machined parts. But Type III is only suitable for pre-coating aluminum and titanium alloys.
Compared to anodizing, powder coating can be applied to any metal CNC-machined part, giving them stronger impact resistance.
