CNC milling - WayKen

CNC Milling

CNC milling is a subtractive form of manufacturing that uses cutting tools to moves and rotates to remove material. CNC milling can be used for cutting and machining operations of various plastic and metal materials. It is suitable for any industry that requires precision components and is also an ideal tool for making molds.

CNC Turning - WayKen

CNC Turning

CNC turning removes material by contacting a cutter with the high-speed rotating workpiece, and is usually used to create round or tubular shapes. The CNC turning process allows the generation of complex external geometries and internal holes, including the machining of various threads.

5-Axis CNC Machining


5-axis CNC machining allows complex parts with multiple side features to process up to five sides in a single setup. This can pay big dividends in better machine utilization, reduce setups and cycle times, and improve quality. The ability of 5-axis machining will make our machining shop more cost-effective for a wider range of work.

Design For Manufacturability

A Quick Guide to Designing CNC Machined Parts

Optimize your designs to avoid unnecessary machining features, limit part complexity, help reduce machining time and costs, and create machined parts faster and more efficiently.

  • Avoid thin walls
    WayKen has 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 machining.
  • Avoid small or raised text
    You may need to mark parts with part numbers or company names. Adding text looks really cool, 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.
  • 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.
  • 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 process.
  • 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.

    CNC Machining FAQs

    We offer product developers parts machined from engineering-grade materials that are suitable for functional testing or end-use applications. Get the support you need on CNC machining by reading the FAQ here.

    We do the following services: milling, turning, drilling, threading, tapping, EDM and wire EDM, custom surface finishing, prototype machining, low volume or one-off part machine runs, modification of an existing part, material sourcing assistance, limited material warehousing and parts dispatching.
    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. 

    We have a 35,000 square foot CNC machining shop with 60+ skilled employees, 16 high performance CNC machines, maintain 24/7 operations, and can deliver over 300 machining projects and 20,000+ machined parts per month.

    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% higher 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.

    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 is 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.

    Maximum Dimensions (3-axis milling): 1270×508×635 (mm).
    Maximum Dimensions (5-axis milling): 450×700×400 (mm), Worktable Diameter Φ400 mm.

    For CNC machining, all tolerances for part dimensions will follow the ISO 2768-1 standards. If desired, you can specify tighter tolerances in the part specification, which will require technical drawings. Typically, we can hold a machining tolerance from +/-0.005″ (+/-0.125mm) to +/-0.002″ (+/-0.05mm).
    Tolerances tighter than +/-0.002″ (+/-0.05mm) will be reviewed by our mechanical engineers. Tolerances are greatly affected by part geometry and type of material. Our project managers will consult with you on every part of your project and will provide the highest degree of precision possible.
    It is important to keep in mind that a tighter tolerance can result in additional cost due to increased scrap, additional fixture, and/or special measurement tools. The best way to apply tolerances is to only apply tight and/or geometric tolerances to critical areas, which will help minimize cost.

    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.

    Yes. WayKen combines the machining capabilities of the best combined 3-axis, 4-axis or even 5-axis CNC milling machines. We also have adopted the latest diamond machining technology in ultra-precision manufacturing. This is a technique called Single Point Diamond Machining (SPDM or SPDT) that can match the ability of 5-axis micro-milling to produce a range of lens and light guides types of excellent optical quality in an array or freeform pattern. With the rich polishing experience, we can get amazing appearance on both inside and outside of the parts, providing fully support to clear and optical prototype development projects.

    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.
    Rejected or non-conforming parts will be documented and communicated based on the type of inspection agreed upon with the customer. Typically, for inspection items without a 2D drawing dimensional report, WayKen may ship parts found with minor non-conformances (that cannot be reworked into compliance and are assumed to not impact the fit, form, or function of the part) for customer review. For any orders with formal inspection with dimensional reports, WayKen will acquire customer disposition on non-conformances for all issues that cannot be reworked into compliance prior to shipping. 

    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.
