Case Applications of CNC Machined Parts
CNC machining is a versatile manufacturing technology used across a wide range of applications. WayKen's CNC machined part examples include products for the aerospace, automotive, medical, robotics, etc.




















CNC Machining Surface Finishing
WayKen provides a full range of surface finishing options for CNC machined parts, from standard as-machined finishes to advanced coatings and platings.
As Machined
As-machined finishes leave visible tool marks straight from the CNC process, with surface roughness between Ra3.2μm and Ra1.6μm. It's the fastest, most economical option, ideal for non-cosmetic or functional parts.
A Quick Guide to Designing CNC Machined Parts
Optimize your designs to avoid unnecessary machining features, limit part complexity, help reduce CNC machining costs and time, and create machined parts faster and more efficiently.
1、 As large an internal radius as possible
Any internal cut will generate a fillet that is half the diameter of the tool used. Milling with smaller tools takes a long time and we recommend that the radius should be greater than 1/3 of the depth of machining. The best bet is to relieve internal corners or allow for as large an internal radius as possible on mating part designs and use the same radius on all inside edges so that the same tool can be used throughout the CNC machining processes.
2、 Avoid overly deep cavities, grooves and holes
The depth of the cavity and groove is usually related to the diameter of the tool used to make the internal fillets, and a good rule of thumb is to keep the cavity depth 3 – 4 times the tool diameter or the groove depth less than 4 times the feature width. Whether blind holes or through holes, the recommended maximum depth is 4 times the diameter and the minimum hole diameter is 1 mm, and it is recommended to design standard size holes. With a standard drill, holes can be machined quickly and with high precision; for non-standard holes, using an end mill will increase costs.
3、 Avoid thin walls
As with tall walls, vibration increases when machining thin features. As a guide, the minimum thickness of thin-walled metal parts should be 0.5-0.8 mm, and the minimum thickness of plastic parts should be 1.0- 1.5 mm. If the walls are for supporting action or taller features, the wall thickness should be increased to avoid vibrations during CNC machining processes.
4、 Avoid small or raised text
You may need to mark parts with part numbers or company names. Adding text looks really cool in the custom CNC machining, but is time-consuming to process; electrochemical etching or laser marking is usually better. If you must cut text, choose recessed rather than raised text whenever possible, keep it simple and large, with a font depth of no more than 0.3mm.
5、 Stick to the standards for threads
Sticking to standard sizes is also important when creating threads. Length should be kept to a maximum of 3 times the nominal diameter of a hole. For blind hole tapping, it is preferable to add an additional length of at least 1/2 hole diameter at the root of the hole. You might also think about using inserts. threaded coils and brass nuts provide longer service life than bare threads, especially in soft materials such as aluminum or plastic, and are easy to install.

CNC Machining Case Study
Electronics Batch Manufacturing of High-End Aluminum Headphone Housings with Custom CNC Machining
WayKen supported a consumer electronics manufacturer in the production of AL6063 headphone housings. By combining 5-axis and 3-axis CNC machining with optimized fixturing and controlled anodizing processes, we ensured precise contours, stable deformation control, and consistent black anodized finishes across 3,000 housing sets designed for high-end headphone products.
Industrial Equipment Precision CNC Mill-Turn Machining for Low-Volume Disc Parts
For a 640-piece order of AL6061-T6 disc parts, WayKen adopted a dedicated mill-turn process to handle six threaded holes, six precision holes, and demanding geometric tolerances. Fine-turning and datum-based machining controlled critical assembly surfaces, achieving 0.001 in flatness and parallelism and 0.0005 in total runout. Specialized inspection fixtures and CMM measurements verified these tight tolerances.

From prototype to production, from 1 to 10,000 pieces, we offer fast turnaround CNC machining of your custom metal and plastic parts with as fast as 3-day delivery.
WayKen has a 35,000-square-foot CNC machining shop. With 70+ skilled employees and 20+ high-performance CNC machines, we maintain 24/7 operations and can deliver over 300 machining projects and 20,000+ machined parts per month in our CNC machining centers.
Our engineering and sales teams will provide one-on-one quote support for your project. Typically, for similar parts, CNC lathes cost 15% less to machine than standard 3-axis CNC milling. In contrast, the cost of 5-axis machining increases, continuous 5-axis CNC milling typically costs over 20% more than an indexed 5-axis machine (also referred to as 3+2 milling), and about double that of a standard 3-axis mill. To achieve the most cost-effective CNC machined parts, larger production runs are recommended to spread the cost of machine setup.
Maximum Dimensions (3-axis milling): 1270×508×635 (mm).
Maximum Dimensions (5-axis milling): 450×680×400 (mm), Worktable Diameter Φ400 mm.
Once the machining process is complete, the CNC parts surface will have slight visible tool marks, called “as-machined” or “as-milled” surface finish. Machined surface roughness (Ra) is standardized at 1.6-3.2 μm, and surface finish requirements can be increased to 0.8-1.6 μm or higher at 0.2-0.8 μm, however, this will require more operating time and higher costs.
In order to provide a meaningful quote, we require the following information:
We accept CAD data in any format, 2D and 3D, including STP, IGES, X_T, DWG, PDF, STL;
The expected quantities, machining processes, and raw materials required;
Any necessary secondary operations, including finishing specifications, heat treatment, anodizing or plating, etc.
Any applicable customer specifications, such as First Article Inspection, PPAP requirements, and required outside process certificates;
Any other useful information, such as target pricing or required lead times.
Designing parts are outside of our scope as a contract manufacturer, but we can provide some guidance on design for manufacturability (DFM). With DFM, we can advise on how to optimize your design and reduce costs while retaining functionality.
In most cases, we will respond to your quote within 1 business day. The best way to help ensure a quick quote is to provide as much accurate and specific information as possible.
In fact, 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 / CMM 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.
