Frequently Asked Questions

What is the difference between CNC and precision machining?

CNC (Computer Numerical Control) machining refers to the automated process of using computer-controlled machines to cut and shape materials. Precision machining is a broader term referring to any machining process that achieves very tight dimensional tolerances. Precision CNC machining combines both—using CNC automation to consistently achieve extremely accurate tolerances, often as tight as +/-.0005 inches, as DM&E delivers.
