What is CNC Machining?

CNC (Computer Numerical Control) machining is a manufacturing process that uses computer-controlled machines to precisely cut, shape, or mill materials such as metal, plastic, wood, or composites. In CNC machining, a computer program guides the machine's movements, allowing for high accuracy and repeatability in creating complex parts and components. This process is widely used for prototyping, custom manufacturing, and mass production, offering benefits such as consistency, efficiency, and the ability to produce intricate designs. CNC machines can perform a variety of tasks, including milling, turning, drilling, and grinding.

Here’s how it works:

CNC (Computer Numerical Control) machining works by using computer-driven machines to automate the process of cutting, shaping, or finishing materials like metals, plastics, and composites.

Design: A part or product is first designed using CAD (Computer-Aided Design) software.

Programming: The CAD design is then converted into a G-code, a programming language that tells the CNC machine exactly how to move and what operations to perform.

Machining: The CNC machine follows the programmed instructions to precisely cut, shape, or finish the material into the desired part.

Finishing: After machining, the part may undergo additional processes like polishing, coating, or assembling.

Frequently Asked Questions

What tolerances can you achieve with CNC machining?

We hold standard tolerances of ±0.05mm for plastic parts and ±0.01mm for metal parts. For critical features, we can achieve up to ±0.005mm (0.0002 inches).

What is the fastest turnaround for a CNC machined prototype?

Simple plastic parts can be machined and shipped in as little as 3–5 business days. More complex geometries or metal parts typically take 5–10 days.

Can you machine both plastics and metals?

Yes. We machine engineering plastics (ABS, PC, Nylon, POM, PEEK, PTFE, etc.) and metals (aluminum 6061/7075, brass, stainless steel 304/316, mild steel, titanium).

What is the difference between 3-axis, 4-axis, and 5-axis CNC machining?

3-axis cuts in X, Y, Z directions – suitable for flat and simple parts. 4-axis adds rotation for undercuts. 5-axis enables complex geometries with a single setup, reducing errors and improving surface finish.

Do I need to provide a 3D CAD file?

Yes, a 3D CAD file (STEP, IGES, STL, or X_T) is required for an accurate quote. If you only have a 2D drawing, we can help convert it to 3D for a small fee.

Can you produce low-volume production runs (100–1000 parts) using CNC?

Yes. CNC machining is ideal for 1 to 10,000 parts where injection molding is not cost-effective. No mold investment required.
