Why Choose Nylon (PA) for CNC Machining?

Nylon, technically known as Polyamide (PA) with the most common grades being PA6 and PA66, is a powerhouse among engineering thermoplastics. While Acetal (Delrin) is stiffer, Nylon is significantly tougher and better at absorbing heavy impact loads without fracturing.

Whether you are designing parts that endure constant friction or heavy mechanical vibration, this material delivers:

Outstanding Wear & Abrasion Resistance: Naturally slick and highly resistant to wear, making it perfect for moving parts, sliding mechanisms, and wear pads.
Extreme Toughness & Impact Strength: Bends and absorbs massive shocks without cracking, outperforming almost all other standard plastics in fatigue endurance.
Excellent Heat Resistance: Nylon 66, in particular, maintains its mechanical properties at high continuous operating temperatures, making it a staple in automotive engine compartments.
High Load-Bearing Capacity: Frequently used to replace heavy bronze or brass bearings, saving weight while providing a self-lubricating effect that reduces maintenance.

As your expert manufacturing partner, XML utilizes specialized chip-breaking strategies and strict thermal/moisture control to machine this incredibly tough plastic with exacting precision.

Nylon (Polyamide) Technical Specifications & Machining Parameters

Mechanical & Thermal Properties	Metric Value	Imperial Value	Test Standard
Density (Specific Gravity)	1.14 – 1.15 g/cm³	0.041 lbs/in³	ASTM D792
Tensile Strength (Yield)	80 – 85 MPa	11,500 – 12,300 psi	ASTM D638
Flexural Modulus	2.8 – 3.0 GPa	400,000 – 435,000 psi	ASTM D790
Impact Strength (Izod Notched)	~ 50 – 60 J/m	1.0 – 1.2 ft-lb/in	ASTM D256
Water Absorption (24 hrs)	1.2% – 1.5% (High compared to Acetal)	1.2% – 1.5%	ASTM D570
Max Continuous Temp	90°C – 100°C	194°F – 212°F	UL 746B
Melting Point	255°C – 265°C	491°F – 509°F	ASTM D3418

Machining Parameters	Technical Specifications
Standard Tolerances	±0.05 mm to ±0.1 mm (Subject to environmental humidity)
As-Machined Surface Finish	Ra 1.6 – Ra 3.2 μm (Smooth, low-friction finish)
Cutting Strategy	High feed rates with moderate spindle speeds; aggressive “peck drilling” and chip-breaking toolpaths to prevent stringy chip wrapping.
Tooling Specifics	Razor-sharp, high-clearance solid carbide end mills to shear the tough plastic cleanly rather than tearing it.
Coolant / Thermal Control	Dry machining with high-pressure air blast. Avoiding water-based coolants completely prevents the material from absorbing moisture and swelling during cutting.
Material Conditioning	Moisture conditioning available post-machining to stabilize dimensions before shipment.
Supported Operations	Heavy-duty CNC Turning (Lathe), 3 & 5-Axis CNC Milling, Gear Hobbing, Drilling & Tapping.

Extensive Industry Applications of Nylon Parts

Aerospace

Nylon’s ability to resist high-frequency vibrations and reduce weight makes it indispensable in flight. We CNC machine wear-resistant aerospace cable pulleys, lightweight structural brackets, and vibration-dampening mounts that survive constant mechanical stress.

Medical Devices

Because it can withstand repeated sterilization and resists chemical degradation, Nylon is trusted in the medical field. We manufacture durable medical instrument handles, custom orthotic joint components, and wear-resistant surgical trays for long-lasting clinical use.

Robotics & Automation

Replacing heavy metal gears with Nylon drastically reduces noise, inertia, and the need for grease. We specialize in manufacturing self-lubricating robotic gears, high-impact automated conveyor rollers, and industrial wear pads that keep factories running smoothly.

Automotive

Nylon 66 thrives in the harsh, high-heat environment under the hood. We precision-machine tough high-heat engine compartment brackets, custom suspension bushings, and durable transmission thrust washers that easily outlast standard plastics.
