What is CNC?

And what are the benefits of outsourcing CNC machining services? CNC (Computer Numerical Control) machining is a subtractive manufacturing technology: parts are created by removing material from a solid block (called the blank or workpiece) using a variety of cutting tools like a fiber laser cutter, water jet cutting machine, automatic fabric cutting machine.

This is a fundamentally different way of producing compared to additive (3D printing) or formative (injection molding) technologies. The material removal mechanisms have a significant impact on the advantages, limitations and design limitations of CNC. More about this below.

Digital production technology for companies

CNC machining services is a digital manufacturing technology: it produces high-precision parts with excellent physical properties directly from a CAD file. Due to the high degree of automation, CNC is price competitive for both one-off custom parts and medium-sized productions.

Almost any material can be cnc milling turning. The most common examples are metals (aluminum and steel alloys, brass, etc.) and plastics (ABS, Delrin, Nylon, etc.). Foam, composites and wood can also be processed.

The basic CNC process can be divided into 3 steps. The engineer first designs the CAD model of the part. The operator then converts the CAD file into a CNC program (G code) and sets up the machine. Finally, the CNC system performs all operations with little supervision, removes material and creates the part.
