This document introduces basic knowledge about machining as an introduction to machine processing. It provides detailed information about machine tools such as the "lathe," which rotates materials and uses cutting tools to shape them, and the "machining center," which performs milling operations with NC control. Maruwa Machinery Co., Ltd., which conducts ultra-precision machining at the micron level, as well as the production of various jigs and precision gauges with over 70 different processing machines, has explained this in an easy-to-understand manner for newcomers and beginners. It is a useful reference, so please take a moment to read it.
