CNC Processing Explanation

From a raw metal block to a precision part—this is how CNC machining turns "impossible" tolerances into reality. Let’s speed through the process in 90 seconds.

Step 1: Design and Programming

First, it all starts on a screen. Engineers draft 3D CAD models, defining every groove, hole, and curve. Then, CAM software translates that design into G-code—the "language" CNC machines understand. No guesswork here; every move is preplanned to the millimeter.

Step 2: Clamping and Calibration

Next, the raw material (aluminum, steel, or even plastic) gets clamped tight on the CNC machine. A probe glides over its surface to "find zero"—calibrating the machine so it knows exactly where to cut. One wrong move? Ruined parts. Precision starts here.

Step 3: Machining and Cutting

Now the magic happens. The spindle fires up, spinning a carbide tool at 10,000 RPM. It zips through the material, first roughing out the shape (fast, but not perfect), then finishing with tiny, precise cuts—down to 0.001mm tolerance. Chips fly, but the end result? Flawless.

Last step: inspection

A coordinate measuring machine (CMM) checks every dimension to make sure it matches the design. What started as a hunk of metal? Now a part that powers cars, planes, or medical devices. That’s CNC machining—precision, speed, and possibility.
