CNC Milling
High-precision CNC milling with tolerances down to ±0.001"", fast delivery in as little as 1 day, and cost-effective solutions for every stage of development.
CNC Milling for Every Geometry
From basic 3-axis to high-precision 5-axis CNC milling, we offer full-spectrum capabilities to produce tight-tolerance parts in metal and plastic — ideal for rapid prototyping and end-use production.
3-Axis CNC Milling
Ideal for flat surfaces, slots, and simple contours, 3-axis milling delivers reliable precision at lower costs. It’s the perfect choice for straightforward parts with tight tolerances and consistent quality."
4-Axis CNC Milling
4-axis milling adds rotational capability, allowing access to multiple sides of a part in a single setup. This reduces manual repositioning and increases accuracy — a smart solution for moderately complex geometries."
5-Axis CNC Milling
5-axis milling handles the most intricate, multi-angled components with ease. Capable of creating undercuts and complex curves, it enables unmatched freedom of design and surface finish in one continuous operation."

FAQs About CNC Milling
CNC Milling – Frequently Asked Questions
What materials can Topmetry mill?
We can mill a wide range of metals (aluminum, steel, brass, copper, titanium) and plastics (ABS, POM, PC, nylon, acrylic, etc.).
What tolerances can you achieve for CNC milling?
We typically hold tolerances of ±0.005 in (±0.125 mm) or better, depending on part geometry and material.
How do you ensure precision in multi-axis milling?
We use advanced 3-axis, 4-axis, and 5-axis milling machines, paired with skilled operators and continuous quality monitoring, to ensure accuracy across complex geometries.
Can you finish my CNC milled parts?
Yes. We offer a full range of surface finishes such as anodizing, painting, powder coating, plating, polishing, and bead blasting.
Do you handle both prototypes and production runs for milling?
Yes, our CNC milling services are designed for both rapid prototyping and volume production.
