Looking for a competitive advantage, rapid turnaround supplier for your CNC machining project? Conco is an expert in CNC Machining Services in China for both prototypes and machined parts of end-use. Through our wide network of manufacturers, Conco’s CNC machining services can accommodate your needs from prototyping to series manufacturing. Whether your project is big or small, on the simpler side or highly complex, Conco can make it happen.
Our CNC machining services include milling and turning of various materials, as well as drilling, tapping EDM (Electrical Discharge Machining), and wire EDM. Our ISO 9001 certified production process, combined with professional experiences and advanced CNC machines ensures your parts are made right the first time, every time.
Conco standard tolerance is applied to ISO 2768 (medium) for machined plastic and ISO 2768 (fine) for machined metals. Typically, we can hold a CNC machining tolerance from ±0.005″ (±0.125mm) to ±0.002″ (±0.05mm). If tighter tolerances are required, a 2D drawing with complete information will be necessary. Our engineering team will communicate with you the critical dimensional tolerances and provide the highest degree of precision possible.

The two are not the same. Drilling is only suitable for making holes axially. A CNC mill can move laterally to remove material in that way. There are different types of milling tools to either mill axially, laterally, or both ways. Axial cutting needs teeth on the tip of the cutting head. Lateral cutting means that the teeth have to be perpendicular to the circular cutting head.
Conco partners offer state-of-the-art machinery to guarantee great results with precision machining. This includes 5-axis milling equipment as well as live tooling possibilities. Driven tools, or live tooling, significantly reduce production times by making different operations possible without the need for a change of tools.
Conco offers custom CNC milling services for plastic and metal parts. With our multi-axis CNC machining centers, we can produce a variety of simple and complex CNC-milled parts. Whether you need prototypes or product parts, our experienced teams can provide them with high standards and cost-effectiveness.
We also have many surface finish options so that your machined part is exactly what you need it to be.
Add radiuses to internal edges. Most cutting tools are cylindrical, thus achieving internal sharp edges can be tricky. It’s recommended to have internal radii of 130% of the milling tool radius.
Avoid excessively thin walls. Thin features are prone to vibrations and deformations due to heat generated from cutting. This lowers the achievable tolerances.
Specify tolerances only where needed. Adding too tight tolerances will drive up the cost. Standard tolerances according to ISO 2768-m will be applied by default.
Avoid designing unnecessary features and features that can’t be machined. The same goes for really small features, which would need to be micro-machined. Our partners have micro-machining capabilities but this is an expensive process.
Design holes with standard sizes, as these can be machined with standard drill bits. Non-standard holes are treated as cavities and machined with an end mill tool.

CNC turning is the process of removing material from a rotating workpiece using the linear path of tools on a CNC lathe. From a simple perspective, the main elements involved in this process are the rotating spindle in which your work part is clamped and the cutting tool that is mounted on a turret.
CNC turning cuts the shape by spinning the metal part. The cutting tool can move axially in 2 ways – along the side of the part as well as to and from.
Thus, the automated system controls the cutting tool, bringing it into contact with the workpiece, while the part itself is turning. As a result, bits of swarf are cut from the metal to produce the required shape.
Turning can perform many operations like turning, boring, threading, etc. Highly skilled machinists can create precision parts on all types of CNC lathes but contemporary machining centers help to assure a level of similarity close to being identical between the machined parts.
Sliding head turning is also available to lower the production times as well as the final price. Comparing sliding head turning to traditional fixed-head CNC machines, the production cycles are about twice as long for the latter.
Our fast, precise CNC turning services include the provision of extensive guidance and support to clients from the beginning up until the completion of parts in our CNC machining center.
CNC machining is a metal fabrication method where written code controls the machinery in the manufacturing process. The abbreviation CNC stands for computer numerical control.
Contemporary CNC machines are fully automated, eliminating the need for a manual operator to directly control the CNC machine. The code determines everything from the movement of the cutting head and the part to spindle speed and RPMs. All they need is digital files with instructions about cutting trajectories and tooling.
The part’s shape and mechanical properties are defined in a CAD file. This information is then turned into manufacturing directives for CAM (computer-aided manufacturing) software. Lastly, it is transformed into specific commands for a particular machine and loaded onto the CNC machine.
CNC machining is a subtractive manufacturing method. This means that material gets removed during the production process, making it the opposite of additive manufacturing, e.g. 3D printing.
The benefits of CNC machines include great positioning accuracy and high repeatability, so you get consistent results every time. CNC machining is suitable for both rapid prototyping and high-volume serial production.
Although the majority of machining processes in the manufacturing industry are controlled by computers, then in a traditional sense CNC machining refers to only a few of these automated processes, namely milling, turning, and drilling.
The material selection includes metals and plastics, including steel, stainless steel, aluminum, titanium, PE, POM, etc. Wood is not currently available but we are looking to add more materials in the future.
To provide a meaningful quote, we require the following information:
We accept CAD data in any format, 2D and 3D, including STP, DWG, PDF, and STL; The expected quantities, machining processes, and raw materials required; Any necessary secondary operations, including finishing specifications, heat treatment, anodizing or plating, etc.
In most cases, we will respond to your quote within 2 business days. The best way to help ensure a quick quote is to provide as much accurate and specific information as possible.
There is no standard delivery time and we will schedule production based on the current workload. Once your purchase order is received, documentation is completed, and materials are available, we will provide prompt feedback on the exact delivery time, which can usually be anywhere from 3 business days to a few weeks, depending on the complexity of the part and quantities of parts ordered.
If you’re worried about Quality Assurance for international orders, an ISO-9001-certified factory won’t let you down. With dedicated inspection equipment and skilled QC/QA staff, we can provide 2D reports / 3D scan reports to ensure the quality of your parts is within the expected range. 100% of all dimensional tolerances, geometric tolerances, and print notes will be documented according to our MIL-STD-105E-based statistical sampling plan with zero rejects. All dimensional inspection reports will be shipped with your parts.
Complete CNC Machining Services from prototype to production ensure high quality, fast delivery and competitive prices.
