Computer numerical control (CNC) machining, also known as precision grinding, is a versatile process in which layers are gradually removed from a piece of material, or “workpiece,” to leave the desired shape for a component or piece of equipment. Recent advances in automation have made this process more popular and widespread than ever before, but many misconceptions about it remain in the public imagination.

What Are Some Common Precision Grinding Myths?

1. Anyone Can Operate a CNC Machine

Increasing automation has led to the belief that anyone can operate precision grinding equipment. However, while automation has significantly reduced costs and cycle times, competency, training, and experience are still vital for successful CNC operators.

Operators must still be capable of loading and unloading workpieces, starting and monitoring cycles, making adjustments, evaluating the acceptability of the finished piece, recognizing and replacing dull tools, and much more.

2. Precision Grinding Is Expensive

The availability of advanced computer-aided design & computer-aided manufacturing (CAD/CAM) software and sophisticated machining parts have actually made precision grinding more affordable than ever.

Built-in features allow operators to quickly set up parts, and high-speed cycle times have made the process less costly for manufacturers and customers as well. While it’s true that parts are more cost-effective to produce in bulk, even limited numbers of specialized parts are more affordable to produce with modern CNC equipment.

3. Precision Grinding Has Limited Design Options

While this may once have been true of precision grinding, increasingly sophisticated technology and multi-axis machining centers offer almost limitless possibilities in creating complex designs. Precise designs can be executed to manipulate tools around a varying number of axes according to predesignated specifications.

Technicians may also make use of electrical discharge machining (EDM) to further refine machined pieces depending on their material qualities, whether they’re metal, plastic, glass, or composite.
