What We Good At CNC Machining Processes
CNC Milling
CNC milling is a subtractive manufacturing method that uses a cutting tool to move and rotate to remove material. CNC mills 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 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 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 CNC shop more cost-effective for a wider range of work.

Case Applications Of CNC Machined Parts
CNC machining is a versatile manufacturing technology that can be used for a wide range of applications. Common examples include components for the aerospace, automotive, medical industries and etc.
There are a wide variety of materials that can be machined using CNC technology, our provides CNC machining quotes for more than 30 engineering-grade plastic and metal materials. In terms of finishes, various types of surface finishes can be applied to CNC machined parts.
CNC plastic processing is widely used in many fields. It is suitable for products with high performance electronic insulation requirements and parts with insulation structures in motors and electrical equipment, such as FPC reinforcement plates, PCB drilling pads, electrical (electrical appliances) ) Equipment insulation panels, electronic switch insulation panels, etc. More than 30 engineering-grade materials are available for CNC plastic machining. Machined plastic parts are 100% functional and capable of mechanical testing. In addition, it is also widely used in chemical machinery, anti-corrosion equipment, wear-resistant parts, transmission structural parts, household appliance parts, automobile manufacturing parts and other fields.
CNC metal processing is widely used in aviation, aerospace, automobiles, molds, new energy and other fields. For example, it can be used to process high-precision parts such as aircraft structural parts, engine parts, and turbine blades. Whether it’s a prototype or end-use part, our mastery of CNC metal machining technology helps us achieve tighter tolerances, faster turnaround times and more challenging manufacturing projects. At the same time, higher requirements are also put forward for the performance, accuracy, stability and other aspects of the equipment.
The surface treatment of CNC Machined parts is mainly to increase their corrosion resistance, improve appearance, enhance hardness, etc.
Coating
Surface treatment is a very important part of CNC Machining parts manufacturing. The main purpose is to improve the surface properties of parts, including appearance, corrosion resistance, hardness, lubricity, etc. The treatment method usually depends on the product’s materials, design requirements, usage environment, cost considerations, etc. Common baking methods include liquid baking paint and powder baking paint, anodizing, chrome plating, oxidation, and polishing. Take all factors into consideration to select the most suitable surface treatment method. To meet the design requirements of the product and the needs of the user environment. Therefore, during the spare parts manufacturing process, sufficient attention and attention needs to be given to surface treatment.
Electroplated CNC Machining parts
Through a chemical reaction, a layer of other metal is attached to the surface of the workpiece to achieve a certain beautifying effect.
Polished CNC Machining parts
The surface of CNC Machining parts is made smooth through mechanical or chemical methods to increase its appearance and texture.
sandblasting CNC Machining parts
A process that uses high-pressure airflow to spray abrasives onto the surface of an object to achieve surface polishing or texturing.
Anodized CNC Machining parts
By forming an oxide layer on the surface of CNC Machining parts, it improves its hardness and corrosion resistance.
-Finishes: We support one-stop CNC machining surface finishing to meet the visual and functional requirements of any design. Including sanding, sandblasting, mirror polishing, painting, printing, laser etching, anodizing, electroplating, nickel plating, chrome plating, powder coating, etc.
What kind of surface treatment do you require?
Selecting the appropriate surface treatment method depends on factors such as the CNC Machining part’s use, material and requirements, as well as production costs
Our 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.
Design For Manufacturability
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.
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.
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.
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.
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.
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.

What is the typical cost of a CNC machined part?
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.
What information do you need to quote my part?
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.
I don’t have CAD data, can you help me design the part?
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.
What is your lead time?
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.
What kind of surface finish does CNC machining leave?
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.
