Precision CNC Machining for Small-Run, Custom, and Unique Components
Introduction
Modern industries increasingly demand flexibility, speed, and precision in part manufacturing, especially for small-run, custom, and unique components. Precision CNC machining is ideally suited to meet these demands. Whether you're creating aerospace brackets in quantities of ten or intricate medical enclosures with ±0.005 mm tolerances, CNC technology ensures consistency, complexity, and customization at scale.
At Neway, our CNC machining services are designed to deliver high-accuracy, short-run metals and plastics components optimized for fast delivery and functional excellence.
Why CNC Machining is Ideal for Small-Run Custom Parts
Unlike mass production methods that require expensive tooling and long setup times, CNC machining provides:
Digital repeatability: CAD/CAM-driven processes ensure every unit meets design specifications precisely.
Quick setup for low volume: Ideal for 1–500 units production runs.
No need for hard tooling: Designs can be changed rapidly without retooling, supporting iteration and customization.
High Precision Capabilities
Precision CNC machining can achieve:
Tolerances: As tight as ±0.005 mm
Surface finishes: As smooth as Ra 0.8 µm
Hole location accuracy: Within ±0.01 mm, critical for assemblies
This level of precision is essential for components in:
Aerospace (brackets, housings, turbine accessories)
Medical devices (implants, enclosures, diagnostic equipment)
Industrial automation (custom jigs, fixtures, and gears)
Electronics (heat sinks, connectors, housing frames)
Material Versatility
Neway machines a wide range of materials to meet application-specific needs, including:
Metals
Stainless steel: 304, 316 for corrosion-resistant medical and marine parts
Copper alloys: C18200, Brass 360 for electrical and plumbing systems
Tool steels: D2, H13 for durable dies and forming components
Plastics
POM (Delrin): Low-friction, high-stiffness parts
PEEK: High-performance, chemically resistant components
Nylon, ABS, PC: Cost-effective engineering thermoplastics for custom housings and prototypes
