Nylon CNC Machining Description
CNC machining nylon (polyamide/PA) is a nylon machining process that uses computer-controlled cutting tools to customize nylon into specific components. Nylon is one of the most versatile of the preferred engineering thermoplastics. It is very strong while remaining lightweight with a combination of wear resistance and chemical stability.
The ideal option for producing prototypes and parts with precision and accuracy at low-to-medium volumes, CNC machining produces nylon parts with tighter tolerances and better surface finishes than those produced through injection molding.

Handling Advanced Nylon Machining Problems
Find out how we assist industry frontrunners with engineering mastery in addressing moisture absorption, tool wear, and accuracy concerns.
Automotive Fuel Components Moisture Absorption
The Challenge
A Tier-1 supplier risked a costly transition to Acetal due to assembly failures with Nylon 66 parts that moisture absorption during transport caused an increase in size by 0.15mm.
Our Solution
We developed a Moisture-Compensated Machining Protocol: conditioning raw stock, predictive CAM scaling moisture absorption, and dry air-blast cooling.
The Result
Optimized the existing Nylon 66 design, the assembly plant achieved a 100% fit rate and the client 35% material cost savings.
Glass-Filled Nylon
The Challenge
A robotics startup was challenged with decreasing the inertia of a high-speed arm. Standard plastics did not sufficient tensile strength and aluminum was too heavy.
Our Solution
Using PCD (Polycrystalline Diamond) tooling to manage abrasiveness, we worked 30% Glass-Filled Nylon (PA6 GF30) to the desired parts and incorporated a stress-relieving annealing cycle.
The Result
The components had a 1.6μm superior finish and were 40% lighter than aluminum, which resulted in a 25% increase in robot speed without losing rigidity.
Burr-Free Micro-Machining for Medical Devices
The Challenge
Defining an intricate FDA Nylon 6 fluid manifold with M2 threads. The preceding supplier left behind cross-hole “stringy” burrs, which are considered a potential contaminant.
Our Solution
Multi-stage are high-rake engineering for clean shear, 5-axis single setup milling, and Cryogenic Deburring (to freeze and remove micro-burrs cleanly) engineering.
The Result
Imparted 500 manifolds. Particulate contamination is 0. Contamination is below the limits of the most stringent bio-burden testing, which allowed them to attain ISO 13485 supplier status.
High Voltage Insulators with Superior Surface Finish
The Challenge
Nylon 6/6 switchgear housings were failing due to electrical tracking. Prototypes had a rough surface finish, which trapped dust moisture causing arcing.
Our Solution
The surface topology was the focus of the engineering by adjusting the spindle speed to 12,000 RPM and using Climb Milling for finishing, achieving a mirrored cut.
The Result
The finish achieved was Ra 0.8μm. There was a 20% improvement in breakdown voltage performance in the smoother parts.

Custom Nylon Prototype Machining FAQs
A variety of items can be made through services of cnc machining of nylon. Some examples are gears, bearings, bushings, spacers, and housings. Also, customized nylon plastic components can be created for distinct fields. Some of the most done grades are regular nylon, nylon 6, nylon 66, nylon 12 and other high-performance nylons. Polyamide mixtures are utilized for parts where dimensional stability, low friction, and wear resistance are important. With CNC milling and cnc turning, you can create components with finished surfaces. A variety of polishing and dye options are available to complete your custom component to your specification.
Some industrial applications use parts of mouth pieces as interfaces with bending, wear and tear, and environmental forces. Examples would be parts of conveyors, guide machines, gaskets, and insulators. Some types of nylon can be used as wear surfaces. Afew properties of nylon are strong against impacts, abrasion, and some chemicals. These properties make nylon useful for parts. Some examples would be in automotive, aerospace, trains, and manufacturing tools. In many situations, stability and ease of machining measure the efficiency of the entire unit.
Compared to other thermoplastics like PEEK or polycarbonate, polyamide, or nylon, offers exceptional combinations of properties including mechanical strength, chemical resistivity, low friction, and wear resistance. In addition, nylon is a synthetic polymer family consisting of nylon 6, nylon 12, and nylon 66, with each variant having a different property set; nylon 6-6, for example, has greater heat resistance and rigidity, while nylon 12 has superior moisture resistance and greater stability regarding dimensional changes. Because of the increased precision and ease with which nylon can be machined, it is a popular choice for many applications of machining.
Definitely. With the correct choice of materials and with the right tool paths and cutting instruments, certain cnc machining of nylon can be done with a high degree of tolerance and consistency in dimension. Even though certain nylon strands can be hygroscopic (which leads to moisture absorption and can affect their uniformity), with proper conditioning, pre-drying, or post-machining, the water can be removed from the strands, and precision can be improved. We have many quality criteria to meet any criteria you have regarding uniformity and detail of the surface.
Depending on the part geometry, both CNC turning and CNC milling can be used for nylon parts. CNC milling is best for nylon due to the ability to work on more complex shapes and features, such as tight tolerances, while CNC turning is more effective on cylindrical workpieces, such as shafts, bushings, and other round parts. Because of nylon’s decent machinability and low friction, there can be high feed rates as long as the appropriate tooling is used. In order to ensure longer tool life and high quality finished parts, tool selection, spindle, and coolant strategies are derived to control temperature and friction in order to minimize surface abrasion and friction.
In many general-use, high-stress applications, nylon does very well due to its high tensile strength as well as its high wear resistance. PEEK, however, does much better than nylon in very high temperatures and more aggressive chemical environments. When it comes to impact resistance and, to a degree, clarity, polycarbonate is a great material to work with. However, it typically does not hold up to abrasion as well as nylon does. In extremely aggressive environments, peek is the best option. But for Typical industrial load applications, often nylon 6-6 or reinforced nylons are the best material used for a budget-conscious, yet highly effective part.
Secondary machining for nylon can also include polishing, dyeing, and tapping for the final surface finishing and for increasing functionality. Surface finishing adds wear resistance and reduces friction for bearing surfaces. Chemical resistance and dimensional stability can be improved with sealing, coating, or annealing. If parts have to be made to specific esthetic or functional requirements, be sure to discuss finishing requirements early so that the machining and material selection align with the desired outcome.
To request the manufacturing of custom nylon parts, you must first assemble the necessary part drawings or use a 3D modeling application to configure your parts. Specify the materials to be used along with their tolerances for the application, ambient conditions, loads, desired surface finish, and other application conditions. Most online shops have systems whereby a quote, or instant quotes, can be generated; if not, please contact us to configure preferred materials (nylon 6, nylon 66, nylon 12, etc.), machining methods (faq milling, faq turning, etc.), and delivery schedules. Custom nylon plastic parts engineers excel in incorporating nylon as the preferred machining polyamide in order to provide a solution that can meet your application needs.
